Contents
| Trouble type | Sheet feeder up/down drive failure (upper) | |
| Trouble code | C1125 | |
| Rank | B | |
| Detection timing | <When FS-535+PI-505 is installed> The tray lower limit sensor /Up (PS205) or tray upper limit sensor /Up (PS204) are not turned ON even after the set period of time has elapsed after the tray lift motor /Up (M201) is energized. | |
| Trouble isolation | Post Inserter | |
| Relevant electrical parts | -Tray lift motor /Up (M201) -Tray upper limit sensor /Up (PS204) -Tray lower limit sensor /Up (PS205) -PI drive board (PIDB) -FS control board (FSCB) |
(2)Procedure
| Step | Action | Control signal | Location of electrical components |
| 1 | Check the connector between M201-relay CN203-PIDB CN54 for proper connection, and correct as necessary. | – | – |
| 2 | Check the connector of M201 for proper drive coupling, and correct as necessary. | – | – |
| 3 | Check the connector between PS204-relay CN235-PIDB CN55 for proper connection, and correct as necessary. | – | – |
| 4 | Check the connector between PS205-relay CN235-PIDB CN55 for proper connection, and correct as necessary. | – | – |
| 5 | PS204 I/O check, sensor check | PIDB CN55-8 (ON) | PI-505 5-C to D |
| 6 | PS205 I/O check, sensor check | PIDB CN55-7 (ON) | PI-505 6-C to D |
| 7 | M201 operation check | PIDB CN54-7 to 8 | PI-505 4-C to D |
| 8 | Replace M201 (Part# A10YA6560) | – | – |
| 9 | PIDB ICP2 conduction check | – | – |
| 10 | Replace PIDB (Part# A10AH01001) | – | – |
| 11 | Replace FSCB (Part# A2Y1H10002) | – | – |
