Contents
| Trouble type | Sheet feeder up/down drive failure (lower) | |
| Trouble code | C1124 | |
| Rank | B | |
| Detection timing | <When FS-535+PI-505 is installed> The tray upper limit sensor /Lw (PS209) or tray lower limit sensor /Lw (PS210) are not turned ON even after the set period of time has elapsed after the tray lift motor /Lw (M202) is energized. | |
| Trouble isolation | Post Inserter | |
| Relevant electrical parts | • Tray lift motor /Lw (M202) • Tray upper limit sensor /Lw (PS209) • Tray lower limit sensor /Lw (PS210) • PI drive board (PIDB) • FS control board (FSCB) |
(2)Procedure
| Step | Action | Control signal | Location of electrical components |
| 1 | Check the connector between M202-relay CN206-PIDB CN56 for proper connection, and correct as necessary. | – | – |
| 2 | Check the connector of M202 for proper drive coupling, and correct as necessary. | – | – |
| 3 | Check the connector between PS209-relay CN237-PIDB CN53<A> for proper connection, and correct as necessary. | – | – |
| 4 | Check the connector between PS210-relay CN236-PIDB CN53<A> for proper connection, and correct as necessary. | – | – |
| 5 | PS209 I/O check, sensor check | PIDB CN53<A>-8 (ON) | PI-505 8-C to D |
| 6 | PS210 I/O check, sensor check | PIDB CN53<A>-11 (ON) | PI-505 9-C to D |
| 7 | M202 operation check | PIDB CN56-5 to 6 | PI-505 7-C to D |
| 8 | Replace M202 (Part# A10YA6560) | – | – |
| 9 | PIDB ICP2 conduction check | – | – |
| 10 | Replace PIDB (Part# A10AH01001) | – | – |
| 11 | Replace FSCB (Part# A2Y1H10002) | – | – |
