Troubleshooting. JAM. 5. Misfeed at the image transfer section
Contents
| JAM Type | Detection timing | Relevant electrical components |
|---|---|---|
| Paper image transfer section misfeed detection | • The exit sensor (PS3) does not turn ON even after the lapse of a given period of time after the registration sensor (PS1) turns ON. • The registration sensor (PS1) does not turn OFF even after the lapse of a given period of time after the PS1 turns ON. • The registration sensor (PS1) turns OFF before the lapse of a given period of time after the PS1 turns ON. • While the main motor (M1) is rotating, the machine cannot detect that the registration sensor (PS1) does not Keep ON continuously for the given period of time. |
• Registration sensor (PS1) • Exit sensor (PS3) • Registration clutch (CL1) • Main motor (M1) • MFP board (MFPB) |
| Size error detection | The registration sensor (PS1) does not turn ON even after the lapse of a given period of time after the PS1 turns OFF. | |
| Detection of paper left in image transfer section | • The registration sensor (PS1) turns ON and exit sensor (PS3) turns ON at timing when the power switch is turned ON, the door and/or cover is opened and closed, or a paper misfeed or malfunction is reset. • While feeding the paper, paper misfeed or malfunction occurred or the paper is left by opening the door or the cover, and the exit sensor (PS3) does not turn ON even though the registration sensor (PS1) turns ON. |
