Troubleshooting. FREQUENT PAPER JAMS
If there are frequent paper jams, check SP7504 in section “Service Tables”. If these locations have frequent jams, do the procedures described below.
Symptom 1: Jams when paper is fed from a by-pass tray that is not used frequently
If the customer does not use the by-pass tray frequently, the rollers can become worn.
- Visually check the by-pass tray pick-up, feed, and separation rollers.
- If these rollers are paler than the rollers in paper trays that are more frequently used, replace the rollers in the by-pass tray.
NOTE: For more details, see 3. Replacement and Adjustment, “3.11.12 By- Pass Tray Rollers.”
Symptom 2: Jams with noise from the paper feed unit
- Remove the paper feed unit.
- Loosen screw [A].
- Push the motor [B] toward the tray side, then tighten the screw [A].
- Loosen screws [C] and [D], let the spring move the unit to the correct position, then tighten the screws.
Symptom 3: Other
- If none of the two symptoms 1 or 2 applies, do this procedure.
- Use SP7504 to check the jam counts and find which SPs have high counts.
