Introduction

Thank you for selecting the Martin Yale Model 959 Folder. Your folder and all the components were 100% tested at our factory.

We folded, perforated, and scored paper, performing over 100 individual functional checks on this folder.

Please read and understand this manual completely before attempting to operate the folder. This will prevent most common prob-

lems and eliminate operator-associated errors. Most performance related problems are due to inexperience with the wide range of

machine adjustments which are available to you. Understanding these instructions is vital to years of excellent performance by a

time-tested machine.

WARNING! This machine contains moving parts. Never connect power to the machine until you are

ready to set up and operate the folder. During setup, operation, and maintenance keep hands, hair,

loose clothing, and jewelry away from all moving parts. Serious bodily injury could result. Service,

or disassembly of side covers should only be attempted with the power disconnected and locked

out. The AC outlet must be nearby and not blocked.

1.0 Nomenclature

The nomenclature below will be used to describe accessories and

parts of your folder found in Fig. 1:

2.0 Basic Set-Up

Un-pack the folder and save all the packaging. Inside the main

carton, locate a box containing the 2 fold tables and box contain-

ing the feed table, exit table, these instructions, and a bag con-

taining 3 allen wrenches and the handwheel. Remove the card

board pad (s) from the bottom of the folder and place the

machine on a sturdy, flat table or bench.

CAUTION: Do not plug the power cord in until

the basic set-up is complete.

Begin the basic set-up as follows:

Handwheel: Install on the main roller shaft (Fig. 1).

Feed Table: With the allen wrench provided, loosen the guide

fingers and rotate them up and

away. Insert the front end of

the feed table onto the locator

pins near the 1st roller and

gently lower the back end

down onto the back pins (Fig.

2).

Note: Turn the handwheel counter clockwise while lowering the

table to easily engage the feed drive gears. Never drop or force

the table down, as this may result in damage to the drive gears.

Fold Tables:

Install the fold tables onto the locator pins with

the folding (open) end towards the rollers (Fig. 3 & 4).

Note: Turn the

handwheel counter-

clockwise while

lowering the table

onto the back pins

for easier insertion.

Turn clockwise

when removing the

tables. Be sure the

tables are fully

seated on the pins.

Exit Table: Install exit

table by engaging tabs into

slots provided on the con-

veyor table (Fig. 5). Lower

into position as shown in

Fig. 1.

Accessory Shaft Journals:

Located on the side oppo-

site the handwheel are two

accessory shaft journals

(Fig. 6). These journals are factory installed. Due to vibration in

shipment, they may come loose. Check that the journal shafts are

pushed into the accessory shafts place and rotated clockwise to

lock in place. Test by pulling on the journals; they should not

come out.

2.1 Retarder Adjustments

Loosen 2 socket head set screws on retarder assembly and rotate

until retarder wheel is centered over feed roller. Use the retarder

template shown in this manual (cut out along line), place bottom

edge of the template on feed table and over rollers until the angle

of the template meets the retarder assembly. Rotate retarder until

it is parallel with retarder template, making an angle of 83

degrees. Tighten the two socket head set screws on retarder. See

Fig. 7.

2.22 Guide Finger Adjustments

The height adjustment of the guide fingers should be approxi-

mately 1/32" from the surface of the feed table. See Fig. 7A.

This guides the paper more evenly and accurately into the rollers

for folding. The angle of the guide fingers should be approxi-

mately 90 degrees to the feed table surface. See Fig. 7A. This

will reduce the possibility of paper lifting too high, thus wrin-

kling the paper and possibly causing the machine to jam.

Connect the power cord to a properly rated and grounded outlet.

This concludes the basic set-up of your folder. This does not in

any way indicate that the folder is ready for use. You must com-

plete the Operation section of this manual before turning the unit

to the ON position.

3.0 Operation

When the folder has been properly adjusted and turned to the

ON position, the stock to be folded is placed upon the feed table.

The stock is then automatically fed into one or both of the fold

tables, depending on the type of fold or folds desired, and the

folded sheets are delivered onto the exit table in an overlapping

row.

3.1 Adjust Retarder

Directly above the feed roller is the retarder, mounted in an

adjustable housing. This retarder permits automatic feeding of

various stock thicknesses when adjusted properly. The thumb

screw control raises and lowers the retarder. Place a sheet of

paper to be folded between the feed roller and retarder roller, and

while the folder is running, hold the sheet firmly to prevent it

from feeding into the rollers. Rotate the thumb screw clockwise

to increase pressure or counter-clockwise to decrease pressure.

The retarder is properly set when you have a noticeable drag on

the paper, yet not so tight that you cannot prevent the paper from

being fed. The paper should separate and feed one sheet at a

time. If two or more sheets are fed together, turn the thumb

screw on the retarder assembly clockwise slightly to increase

pressure.

WARNING: Please be sure to adjust the allen screws 1/4 turn

past snug. DO NOT OVERTIGHTEN. Doing so could

damage the Retarder Assembly.

Note: When changing to a different weight of paper, this setting

must be altered. The retarder roller may be rotated to get a new

surface as the old one wears. Loosen the screw and nut and

rotate the retarder to a new position. Retighten screw and nut.

3.2 Folding

The fold tables can be installed with either end in the machine.

One end is a deflecting end, and the other is a folding end. See

Fig. 3. When the deflecting end is in the machine, the sheets

cannot enter the fold table. They simply continue along the paper

path. If the folding end is in the machine, the sheets enter the

fold table to become folded before continuing along the paper

path. The location of the fold is determined, for any given

length of sheet, by the location of the adjustable paper stop. This

location is read directly from the fold rulers, which are located

on either side of the fold tables.

3.2.1 To relocate a paper stop:

Loosen the thumb knobs on top of the paper stop assembly

about two full turns (counterclockwise). A spring under

each nylon split-nut helps to disengage the split-nut from the

micrometer rod threads.

Place the thumb on top of the left and right locking knobs

and with your fingers grasp the split-nut for control. Slide

the paper stop assembly parallel along the micrometer rods

to its required position. Turn the thumb knobs clockwise to

lock paper stop into its new position.

Make test fold and check fold accuracy. Fold corrections

can be made by loosening the thumb knob 1/4 - 1/2 turn.

The micrometer wheel can now be turned, moving the paper

stop for fold corrections. Re-tighten thumb knobs. Repeat

step three until folded material is acceptable.

Note: Rulers are only approximate. Adjustments will have to be

made for various papers, speed of machine, out-of-square paper,

etc.

(4)

3.3 Single Folds

See Fig. 8. The single fold can be made with

either fold table. The selected fold table

should be inserted folding end inward, and

the other table should be inserted deflector

end inward. Single-folding in the 1st fold

table provides better results when light-

weight paper stock is used, and it generally results in greater

accuracy.

Single-folding with the 2nd fold table will facilitate stacking and

minimize curl when heavier stocks are run. Crushed folds are an

indicator that folding should be done with the 2nd fold table.

3.4 Double Folds

To make the standard double folds in sheets sizes of 6" x 9", 8

1/2" x 11", 1 1/2" x 14", and 11" x 17", refer to the simplified

fold chart on the receiving tray to find the rule settings for the

paper stops. When double folding, the folding end of both fold

tables must be installed with the folding ends inward. For sheets

of other sizes, manually fold a sheet in the desired fashion and

measure the folded sheet to determine approximate fold table

rule settings. Final adjustments can be made by running a sheet

through and readjusting

as necessary with the

micro adjustment. See

Fig. 9 for common

double folds.

Note: The folder

should be run at the same speed during set-up as it will be dur-

ing production to guarantee folding precision.

3.5 Folding Pre-folded Sheets, Bulletins &

Booklets

French or Baronial folds can be made by refolding the folded

stock. See Fig. 10. To fold a pre-folded sheet in half for a French

fold, set the folder up the same way as for a single fold. For a

Baronial fold, set the folder up as for a double fold. Be sure to

adjust the retarder for thickness of paper.

Note: Greater

accuracy will

result if the paper

is scored during

the first folding

operation. This

does not require an extra operation.

3.6 Folding Stapled Sets

We do not recommend folding stapled sets as it shortens the life

of rubber rollers. However, if necessary, we suggest the follow-

ing:

1. Adjust retarder to thickness of stapled set.

Do not attempt to fold more than three (3) sheets at one

time.

Use two (2) staples (one on each side of the feed roller) in

staggered locations.

4. If the above does not work, raise the retarder to maximum

opening, and hand feed individual sets.

3.7 Set The Stacking Wheels

The function of the stacking wheels, which are located on the

conveyor table, is to arrange the folded sheets into an overlap

ping stack. Position the stacking wheel assembly so that the

leading edge of a folded sheet touches the wheels when the trail

ing edge just falls onto the exit table.

For most folds, the deflector faces upward (in a non-functional

position). To eliminate nesting and to improve the stacking of

very short folds, the deflector may be positioned to face down

ward. This is accomplished by removing the spring-loaded

stacking wheel assembly and turning the deflector to a down

ward position. The height of the deflector is also adjustable by

means of slots on the deflector. The deflector (plate only) may

be removed from the assembly when it is necessary to mount

strippers while perforating. Two sets of holes are provided for

positioning the stacking wheels. The front set will position the

deflector closer to the exit for short folded stock.

A stacking wheel hook hangs from the 1/2" tie rod in the exit

area to elevate the stacking wheel assembly, if necessary, for

proper delivery of large sheets. Simply rest the stacking wheel

axle in the curved section of the hook.

3.8 Loading Paper

Adjust the paper guides’ inner edges to the width of the

paper (a ruler on the feed table is provided for easy adjust

ment). Avoid crowding the paper as well as adjusting too

loose. Allow 1/32" of play.

Take a stack of paper about 1/2" to 3/4" in height and jog it

to align the edges.

Place the stack between paper guides. Turn the folder on

and adjust the speed.

The paper should separate and feed one sheet at a time. If

two or more sheets are fed together, turn the thumb screw on

the retarder assembly clockwise slightly in increase pres

sure.

While the folder is operating, more sheets may be added to

the stack on the feed table, but do not overload the stack.

Continue this procedure until the run is complete.

3.9 Speed Control Adjustment

The control knob is a combination On-Off switch and variable

speed control. Turn the knob clockwise to reach the ON position,

and continue to turn clockwise to increase the speed.

(5)

Every stock has an optimum folding speed. Slower speeds are

recommended for lightweight stocks and higher speeds for heav-

ier weight stocks. Note: Changing the speed may alter the fold

dimensions. You can compensate by making a micro adjustment

to the setting of the paper stop. If a jam occurs, turn the machine

to the OFF position immediately and follow the jam clearing

procedure.

3.10 Clearing A Jam

When the folder is properly set up, the chances that a jam might

occur are minimal. If a jam should occur, proceed as follows:

1. Turn the machine to the OFF position immediately.

2. Remove the paper stock from the feed table.

3. Remove the fold tables if necessary.

4. Remove jammed paper by manually rotating the handwheel

to clear the machine. The machine must be cleared of

jammed paper before it is turned to the ON position again.

5. Replace the fold tables that were removed, and resume

operation.

6. If the jam was severe enough to have stalled the motor,

the circuit breaker may have opened. In this case, allow

several minutes for the breaker to cool, and then push the

reset button.

7. See Trouble-Shooting Guide for possible causes of jams.

3.11 Perforating, Scoring and Slitting

Note: Slitter is optional and not supplied. Perforating, scoring

and slitting operations are performed by means of certain acces-

sory attachments fastened to the accessory shafts, which are

located in the exit area of the machine. For slitting or perforat-

ing, the appropriate accessory attachments (slitter or perforating

cutter) must be positioned against the lower backup hub(s) not

in the slot (Fig. 11). For scoring operations, the upper brass

roller must be centered to prevent cut-

ting through the paper. Make sure the

rubber guide rollers are positioned out-

side the attachments and inside the paper

margins. Guide rollers should be posi-

tioned with the outer edges of the rollers

approximately 1/4" from the paper mar-

gins. Both the guide rollers must make

contact with the paper passing through.

Always keep the guide rollers in contact

with their backup hubs on the lower

accessory shaft.

Special Note: The rubber guide rollers should always be adjust-

ed so they contact the paper. This should be done even if your

are not slitting, scoring, or perforating. The rubber guide rollers

help to control the paper exiting from the folding rollers.

3.12 Positioning The Attachments

1. Mark a sheet of paper at the point to be perforated, scored or

slit.

2. Use the handwheel to turn the rollers and pass a sheet

through the machine by hand until it makes contact with the

accessory shaft.

3. Remove the 1st fold table for easier access.

Using the allen wrench supplied, loosen the set screw in the

backup hub and slide the hub on the lower shaft so that the

ground face of the hub coincides with the marked point on

the paper. If scoring, the”V” slot of the lower backup hub

must coincide with the marked point. Position the set screw

over the flat on the shaft. Tighten the set screw. Be sure not

to tighten the set screw against the round surface, as this

will cause burrs and prevent the accessories from sliding

freely.

Note: Only one side or edge of the backup hub is sharpened and

is to be used. The ground side of the backup hub is opposite the

“V” slot (Fig. 11).

Move the accessories into place on the upper shaft. The

proper positions of attachments are relative to the backup

hubs as shown in Fig. 11.

If the accessories are difficult to move or if it is necessary to add

accessories or change their position on the shaft, the journals

(extending out from the ends of the shafts) can be removed to

loosen the accessory shafts.

6. Turn the journals counter-

clockwise and pull them out.

If either one is difficult to

remove, place a pin through

the hole in the journal and

rotate (Fig. 12).

7. Adjust the accessories as

necessary.

8. Replace the journals and

rotate them clockwise until they are locked.

9. Install the stripper if necessary. The stripper, which resem

bles a large safety pin, is found hanging from the 1/2" tie

rod in the

exit area. It

is designed

to keep

lightweight

paper from

wrapping

around the

perforator.

The strip-

per should be installed in the manner shown in Fig. 13.

10. Replace the 1st or upper fold table.

Remember:

If paper is not to be folded, insert the deflector

(closed) ends of the fold tables into the machine.

Note: This concludes most normal operating procedures.

However, there are several adjustments which are not covered in

the operation section. These will be covered later, so please con-

tinue to familiarize yourself with these instructions.

4.0 Maintenance

WARNING! Rotating parts and electrical circuits will

be exposed when side covers are removed. Always

turn the machine completely off and disconnect all

power sources when servicing this machine.

Your folder is a precision machine that has been designed to pro-

vide dependable performance over many years. But, like your

automobile, proper maintenance is important for good perfor-

mance. Read this section carefully for helpful hints to keep your

folder operating at peak efficiency.

4.1 Rubber Folding Rollers

The rubber folding rollers on your folder are made of a special-

ly-formulated compound which will provide accurate, reliable

performance over a long period of time PROVIDED THEY

ARE KEPT CLEAN.

During the course of operation, the rollers tend to pick up ink,

lint, talc, powder, and coatings from paper stock. If left to accu-

mulate on the rollers, these substances can cause the rollers to

become slick and hard. HARD, SLICK ROLLERS ARE THE

MAJOR CAUSE OF FEEDING AND FOLDING PROBLEMS.

This causes: inconsistent folding, inconsistent feeding, wrin-

kling the paper, paper coming out of fold table, gaps between the

rollers, and frequent jamming. If your folder shows any of the

above symptoms, the cause is usually DIRTY ROLLERS.

4.1.1 How To Clean Folding Rollers

It is important that you clean your rollers THOROUGHLY. It is

INSUFFICIENT to just clean the surface. You must get the

ground-in foreign matter out of the rollers.

Note: Use Martin Yale Rubber Roller Cleaner and Rejuvenator.

Do not use detergents, blanket wash, or any abrasive cleanser.

Use of any non-recommended cleaning material may deteriorate

the rollers and void your warranty.

Clean the rollers as follows:

1. Disconnect the power supply cord.

2. Remove the feed table and fold tables to gain easy access to

the rollers.

3. Liberally spray Martin Yale Rubber Roller Cleaner and

Rejuvenator across the rollers.

4. Using a clean cloth or soft nylon brush, press hard, moving

back and forth across each roller. You will see the accumu-

lated ink begin to appear on the cloth or brush. Use the

handwheel to turn the rollers. Continue to apply the roller

cleaner to the entire surface of each roller and clean until no

ink appears on the cloth or brush.

WARNING! Failure to thoroughly and immediately

clean off all residue and cleaning solvents may result

in rollers bonding to each other. This potentially can

lead to damage of the rollers, your machine’s drive

system, and/or the motor.

When your rollers are clean, they should be soft and not hard or

slick to the touch. Regular cleaning will add years of life to your

rollers and will assure you of optimum performance.

4.2 Lubricating Folder

Your folder should be properly cleaned and lubricated EVERY

25 HOURS OF USE to make sure that all moving parts continue

to operate properly.

1. Disconnect the power supply cord.

Remove any accumulated lint and paper dust from the ends

of the rollers and bearings with a 1" paint brush.

Place one drop of light machine oil in the oilite bearings

located at the ends of the roller shafts.

TAKE CARE NOT TO DROP OIL ON THE RUBBER

ROLLER. Oil can make the roller swell and cause folding prob

lems. IF ANY OIL DROPS ONTO THE RUBBER ROLLERS,

WIPE IT OFF IMMEDIATELY.

4.3 How To Clean Feed Tire

The feed tire should be cleaned with a damp cloth with soap and

water or a mild detergent. Do not saturate the feed tire with any

liquid. If unable to remove ink from feed tire, a very small

amount of Martin Yale Rubber Roller Cleaner and Rejuvenator

may be put on a cloth and used to remove the ink. DO NOT

SPRAY OR POUR ANY CLEANER ON THE FEED TIRE.

4.4 Parts and Service

Contact your Martin Yale representative for parts and service.

Include the machine model and serial numbers when ordering.

5.0 Adjustments

Described below are several adjustment which are available to

you on your folder.

5.1 Angular Control Adjustment

This adjustment is factory set and will only be required if the

roller springs are worn, a gap exists between the 1st and 2nd fold

rollers, or you cannot perforate or score parallel to the edge of

your stock. DO NOT MAKE THIS ADJUSTMENT until you

are sure that the paper guides are perpendicular to folding rollers

and that paper is cut square. A crooked fold can be compensated

for by adjusting the paper stops on the fold tables.

Paper pulling to one side after contacting the 1st fold roller can

be corrected by increasing or decreasing the fold roller tension.

Insert the allen wrench provided into the hole in the side cover

near the speed control (Fig. 1). Clockwise rotation of the set

screw inside will result in paper pulling more to the operators'

side (side with handwheel). Counter-clockwise rotation of the set

screw will result in paper pulling more to the side away from the

operator. (Fig. 14). Adjust the screw about 1/8” turn at a time

and test. Do not exceed 1/2” turn in either direction, as it is inef

(7)

fective beyond that. Take care

not to back out the screw too

far as it could fall loose inside

the frame.

5.2 Folder Belt

Tension

Warning! Disconnect the

power cord before making

this adjustment.

Remove right side cover, hand-

wheel, circuit breaker, speed control knob and nut. Check belt

tension on motor timing belt. It should deflect approximately

1/4" - 3/8". If loose, adjust by loosening the four motor screws

and relocate the motor. Reassemble side components.

5.3 Paper Guide Adjustment

Place the paper to be used on the feed table, between the paper

guides. The guides should be placed so that the center of the feed

roller is aligned approximately with the center of the paper. The

guides should be adjusted to allow the paper to move freely

down the feed table without angling to one side or the other.

Paper to be fed into the machine should always be jogged and

aligned to enter the fold tables squarely. The paper guides can be

adjusted to the proper width by loosening the adjustment screw

located underneath the feed table and sliding the rod clamps

sideways. The paper guides are mounted to the feed table with

an adjustment bar. This adjustment bar is fixed on one end and is

adjustable with a 1/4 - 20 lock screw on the other end. To adjust,

place a square against the folding rollers and one paper guide,

loosen the lock screw and move the shaft to square the guide to

the rollers. Lock the screw tightly in place.

6.0 Troubleshooting Guide

Listed below are possible problems with the most likely

cause and recommended solutions. Refer to maintenance

as applicable.

6.1 Machine Will Not Run Or Runs Slow Or

Intermittently

No Power

Check building power supply outlet, fuses, and/or cir -

cuit breaker.

Folder Circuit Breaker Tripped

Allow to cool, then reset by pushing the button in until

it stays. A tripped breaker indicates a more serious

problem such as seized bearings, paper jam, tight

drive belt, or low building supply voltage.

Tight Or Seized Bearings

Check for lack of cleaning and lubrication. Replace if

worn or over-heated (dis-colored). See section 4.2.

Loose Wiring

Due to vibration or improper handling when removing

the control side cover, wire connections may have

become loose or disconnected. See the wiring dia

gram.

Loose or Broken Belts

Adjust or replace as necessary.

Failed Electrical Component

Check speed control, circuit breaker, and motor.

Replace if necessary.

6.2 Paper Will Not Feed

Retarder Adjustment Too Tight

See Section 3.1.

Retarder Roller Worn Out

A flat spot may wear on the bottom of the

retarder roller

after some period of use. To correct, loosen the nut

and bolt that locks the roller from turning. Reposition

the roller with the flat spot facing the

folding rollers.

Tighten the nut and bolt securely to prevent it from

turning.

Excessive Ink Buildup On Feed Tire

See Section 4.3.

Feed Roller Clutch

Turn the machine to the OFF position. The feed roller

should spin freely forward by hand but not backward. If

the feed roller rotates both ways or does not turn for

ward easily, replace the clutch.

Paper Guides Too Tight

See Section 3.8 and 5.3.

6.3 Length of Fold Varies

Speed Adjustment

The length of fold will vary slightly with speed changes.

When adjusting fold table stops, make final setting at

the speed you intend to fold.

Loose Screws On Fold Table Paper Stops

Tighten bolts on bottom of split-nut and eliminate any

excess free play between micro adjustment nuts.

Buildup On Folding Rollers

See Section 4.1.

6.4 Paper Jams or Tears

Double Sheeting

See Section 3.1.

Worn out feed roller rubber: replace as necessary.

Speed Too High

Lightweight stock may require a slower speed.

(8)

6.5 Wrinkling Paper

Retarder Adjusted Too Tight

See Section 3.1.

Feed Roller Clutch

See Section 6.2.

Worn Folding Rollers

Remove the feed table and the fold tables. Rotate the

handwheel slowly and visually inspect for gaps

between all the rollers. Any gap between the 2nd and

3rd or 3rd and 4th rollers indicates worn-out rollers or

worn-out folding roller springs. A gap on the operators'

side between the 1st and 2nd roller may only indicate

the need for Angular Control Adjustment, see section

5.1.

6.6 Paper Jams On Exit Table

Stacking Wheels Seized

Insure that wheels rotate freely.

Stacking Wheel Or Deflector In Wrong Position

See Section 3.7.

Accessory Shaft Guide Rollers

See Section 3.11.

Conveyor Belts Not Turning

Check conveyor drive belt and belt tension rollers.

Stacking Wheel Mis-adjusted

This is characterized by a jam on the exit conveyor

that backs up into folding machine. See section 3.7.

Paper Sticks To Perforating Wheel

Install stripper provided and illustrated in Fig. 13.

See Section 3.12.9.

6.7 Paper Folds Are Crooked

Paper Out Of Square

The fold table paper stops can be adjusted to compen-

sate for slightly out-of-square paper. See section

3.2.1.

Paper Guides Loose

Adjust opening until a single sheet of paper has no

more than 1/32" clearance when placed at the bottom

of paper guides.

Paper Not Cut Parallel

Lay a single sheet of paper at the bottom of paper

guides, and adjust one paper guide to compensate for

this.

Note: One paper guide must be kept perpendicular to the fold-

ing rolls.

Dirty Rollers

See Section 4.1.

6.8 Poor Perforating, Slitting or Scoring

The Cutting Wheel Is Not Tight Against Or Is On The

Wrong Side Of The Backup Hub.

See Section 3.12.

The Cutting Wheel Or Backup Hub Is Dull.

Replace parts if necessary.

The Accessory Shaft Spring Is Worn Causing Shallow

Perforations.

Replace spring if necessary.

The Accessory Shaft Journals Are Not Properly

Installed

See section 2.0.

The Accessory Shaft Guide Rollers Are Improperly

Located

See section 3.11.

Scoring Cuts Through Paper -

Caused by the scoring roll

too sharp (sand lightly) or by the scoring roll not centered

in the groove of the backup hub.

6.9 Perforating, Slitting or Scoring Not

Parallel with Edge of Paper

See Section 5.3.

The Paper Is Not Cut Square Or Parallel.

The paper guides are not perpendicular to the fold

roller.

The Paper Guides Are Too Loose.

See Section 3.11.

Accessory Feed Rubber

Rollers are worn or are not contacting paper as it

passes between accessory shafts.

The Fold Roller Angular Adjustment Is Off

See Section 5.1 (Fig. 14).

6.10 Marks On Paper

Excessive Dirt or Ink On Machine

Insure that no ink or dirt buildup exists on feed roller

rubber, folding rollers, or rubber guide rollers on

accessory shaft.

Ink Is Not Dry

Paper printed with rubber-based inks and glycerin-

based fountain solutions that do not require overnight

press clean-up generally will not fully dry for some

period of time. Wet ink will “smudge” as the printed

stock is rubbed against each other at the retarder roll.

Proper ink chemistry and drying time can reduce this

problem. Also, humidity greatly affects drying time.
