Offset Paper Ejection - Riso ComColor X1 series Technical Manual

Face Down Offset Stapler
●Explanation
1. Paper Feeding
Feeds the paper from the printer into the Face Down Offset Stapler via the Transfer Roller 1.
The paper speed is equivalent to the printer ejection speed.
2. Paper Acceleration
Transfer roller 2 accelerates the paper speed to 700mm/second.
3. Paper De-acceleration
The paper is de-accelerated to the ejection speed of 632mm/second.
4. Ejection Roller
The Ejection roller with the drive elevates up-and-down mechanically against the driven roller positioned
nderneath. During the non-offset paper ejection, the Ejection roller is positioned down, nipped against the driven
roller for continuous paper ejection.
5. Rake Roller
This roller also has up and down position. For stapling job, the roller is positioned down to stock the papers in
the staple area. For non-staple jobs the Rake roller is raised in the up position.
6. Paper Stacking Tray and Reverse Roller
The ejected paper onto the Paper stacking tray slides down along the declined angle of the tray back towards the
eject side.The Reverse roller assists the paper to come back all the way down against to wall to align the papers.

2-2-2. Offset Paper Ejection

The prints are offset ejected out onto the Paper Stacking Tray between sets or between jobs, according to the
selection by the printer driver.
The offset amount is 30mm fixed.
●Explanation
Paper Stacking Tray
1. The movement of the equipment is exactly the same as when ejecting the papers onto the Paper stacking tray
with non-offset function.
2. After each set of prints are ejected out on the Paper stacking tray, the tray is offset 30mm to the other side to
receive the next set of the prints. This is repeated through the print job.
