Troubleshooting. JAM. 6. Misfeed at tray 5 paper feed section
Contents
| JAM type | Tray 5 feed section misfeed |
| Detection timing | The leading edge of the paper does not block the tray 5 vertical transport sensor (PS55) even after the set period of time has elapsed after the tray 5 starts to feed paper. |
| For paper fed from the tray 5, image write start signal permit continues to be disabled for a predetermined period of time after the timing of image write start signal output. | |
| The tray 5 vertical transport sensor (PS55) is turned ON when the power switch is turned ON, a door is opened / closed, or jam/trouble reset is done. | |
| In case paper position is detected as locating properly after power switch is turned ON, door is opened / closed or jam/ trouble reset is done, it is regarded as paper jam at tray 5 feed section. | |
| Misfeed processing location | • Tray 5 right door • Tray 5 |
| Relevant parts | • Tray 5 vertical transport sensor (PS55) • Tray 4 vertical transport sensor (PS45) • Tray 3 vertical transport sensor (PS18) • Registration sensor (PS1) • PC Control board (PCCB) • Printer control board (PRCB) • Tray 5 paper feed motor (M51) • Tray 5 vertical transport motor (M52) |
