SUBJECT: HC FINISHER
[Brief]
With reference to the limited capability of HC Finisher on our HC Technical Bulletin HCT-024,
some rollers have been modified to reduce "paper-feeding-marks (ink-marks)" on the printed
documents.
The new roller is a ceramic coated roller which has ceramic tips on the surface of rubber.
This coating will prevent the roller from catching ink on surface, and reduce a transferring back
on the paper.

[Application Tips]
Please remind that a level of "ink-marks" will be still vary depending on paper type / type of
original / and type of finishing function.
There are two types of possible marks, Paper-feeding-marks and Paper-folding-marks.
1) Paper-feeding-marks:
This modification will be reduced "paper-feeding-marks" on the printed documents.
If you annoy "paper-feeding-marks" problem, please try to replace 7 rollers with the new type
rollers by following attached instruction of "HC FINISHER Roller Replacing Procedure".
(It will be takes about three (3) hours to replace the rollers.)
2) Paper-folding-marks:
Paper-folding-marks will be not removed completely by this modification.
There fore, slight roller marks may appear even though replacing the rollers.
Measures to reduce roller marks:
1. Use "RISO IJ Double-sided Matte Paper".
2. When making booklet, print the cover page in advance and dry it for 30 minutes.
Then set the cover pages into the Cover-sheet-tray (of the finisher), and print the inside
pages of the booklets. (Folding marks do not appear in the inside pages.)
We recommend you to check its performance on your side before installing new rollers on user's
machine.
