| Trouble type | C0211: Manual feed up/down abnormality |
| Rank | B |
| Trouble detection condition | – The bypass upper limit sensor (PS35) is not turned ON (blocked) even after the bypass lift-up motor (M28) rotates for a given period of time after the position is switched from stand by position at paper lift-up plate to the feed position. – The bypass lower limit sensor (PS36) is not turned ON (blocked) even after the bypass lift-up motor (M28) rotates for a given period of time after the position is switched from stand by position at paper lift-up plate to the feed position. |
| Trouble isolation | Manual |
| Relevant electrical parts | – Bypass lift-up motor (M28) – Bypass upper limit sensor (PS35) – Bypass lower limit sensor (PS36) – Bypass set sensor (PS30) – Paper feed/transport drive board (PFTDB) – CPU board (CPUB) – Base board (BASEB) |
Procedure
- Check the connector between M28-relay CN195B-PFTDB CN9 for proper connection and correct as necessary.
- Check the connector of M28 for proper drive coupling and correct as necessary.
