Differences between the MT-C3.5 and MT-C3

Overview

The MT-C3.5 (D052/D053/D054) is basically the MT-C3 with some minor changes applied.

The mechanical parts, controller, and machine layout are the same. There are only four

differences, which are listed below:

1. CPM

Each version of the MT-C3.5 is five copies/minute faster than its MT-C3 predecessor. This

was achieved not by increasing the printing speed, but by reducing the paper interval

(firmware modification).

The following table shows the paper intervals when continuously printing A4/LT-LEF

sheets on each model, along with their printing speeds:

(A4/LT)

Type a 55 270mm/sec 81.9/75.9mm 60 270mm/sec 57.8/57.5mm

Type b 65 362mm/sec 121.6/115.6mm 70 362mm/sec 98.1/92.1mm

Type c 75 362mm/sec 77.7/71.7mm 80 362mm/sec 59.8/53.8mm

2. Cleaning brush rotation speed

The number of rotations is the same on the MT-C3.5a/b, but on the MT-C3.5c, the rotation

speed was increased by 50%. This was in order to prevent blurred images caused by OPC

filming. As a result, the brush can more easily wipe foreign particles off the drum surface.

The increase in speed was achieved by modifying the mainframe gears (MT-C3.5 Parts

Catalog, pg. 121, items 14 and 16).

Note: The differences between the mainframe gears on the MT-C3.5a/b and MT-C3.5c

are the color and P/N.

-MT-C3.5c: White AB011507, AB017760

3. Elimination of the fusing lamp for side heating

The lamp for side heating (listed in the MT-C3 Parts Catalog on pg. 99, item 28) was

eliminated on the MT-C3.5c. This is because the warm-up time on this model (60 sec.) is

30 seconds slower than on the MT-C3 (30 sec.), and as a result, there is no need to

provide additional heat to the roller ends. It has been confirmed that eliminating this lamp

does not affect image quality. This change will make it easier to replace/install fusing

rollers in the field.

4. Firmware modifications

It is possible to use the same firmware on both MT-C3 and MT-C3.5 models, except for

the Engine firmware (the MT-C3 and MT-C3.5 both have their own unique Engine

firmware).
