Symptom
The High Capacity Stacker (SK5010) could exhibit the following symptoms if it is of the initial
production and configured with the Pro C901/C901s mainframe:
A) Shift Tray Jams
B) Roller Marks on Coated Paper
C) Tray Elevation Gear Slippage
Cause
A) Shift Tray Jams Caused by Static Electricity
Static electricity causes the first sheet to stick to the shift tray in low humidity & low temperature
environments, especially with coated paper.
B) Roller Marks on Coated Paper
The flange of the paper exit drive roller generates the roller marks. (It is more noticeable on
coated paper)
C) Tray Elevation Gear Slippage
The tray belt tension allows a max load capacity of 100kg. But the load could exceed this max
capacity when coated thin and heavy paper is fed from the Pro C901/C901s, resulting in
slippage of the gear.
Solution
A) Shift Tray Jams Caused by Static Electricity
Attach Mylars to the surface of the shift tray to prevent static electricity.
B) Roller Marks on Coated Paper
Modify the paper exit drive/driven rollers.
C) Tray Elevation Gear Slippage
Apply higher belt tension, add a timing pulley and modified tension spring.
