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.

1. Visually check the by-pass tray pick-up, feed, and separation rollers.
2. 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

1. Remove the paper feed unit.
2. Loosen screw [A].
3. Push the motor [B] toward the tray side, then tighten the screw [A].
4. Loosen screws [C] and [D], let the spring move the unit to the correct position, then tighten the screws.

Symptom 3: Other

1. If none of the two symptoms 1 or 2 applies, do this procedure.
2. Use SP7504 to check the jam counts and find which SPs have high counts.
3. From the table and illustration below, find which gears must be replaced. Example: For tray 1, if SP7504-012 is high, replace gear A, or if SP7504-008 is high, replace gear B.

   Tray	SP7504 12	SP7504 8	SP7504 9	SP7504 10	SP7504 11
   Tray 1	Gear [A]	Gear [B]
   Tray 2		Gear [A]	Gear [B]
   Tray 3			Gear [A]	Gear [B]
   Tray 4				Gear [A]	Gear [B]

4. Clean the shafts and replace the necessary gears.
5. Replace a gear if its cutout and arrow are not in the same position.
   
6. When you replace Gear [A] or Gear [B], be sure to put the metal face on the outer side, and the arrow must be in view.
7. If a replacement gear is not available, do this as a temporary procedure:
   1) Remove the paper feed unit.
   2) Remove the gear.
   3) Clean the gear shaft and inside the gear.
   4) Attach the gear.
