93-10 (bizhub C759/C659)
Contents
| JAM type | Misfeed at duplex transport section | |
| JAM code | 93-10 | |
| JAM detection timing | The ADU paper passage sensor/2 (PS48) is not turned ON (unblocked) even after the set period of time has elapsed after the ADU paper passage sensor/1 (PS47) turns ON (block) by the paper. | |
| – | Paper jam of a sheet of paper left at the duplex transport section results, if the ADU paper passage sensor/1 (PS47) is turned ON (blocked) or the ADU paper passage sensor/2 (PS48) is turned ON (unblocked) when the main power switch is turned ON, a door is opened and closed, or a misfeed or malfunction is reset. | |
| – | When the main power switch is turned ON, residual paper detection starts between each sensor. Paper jam of a sheet of paper left at the duplex transport section results, if the ADU paper passage sensor/1 (PS47) is turned from OFF (unblocked) to ON (blocked). | |
| – | When the main power switch is turned ON, residual paper detection starts between each sensor. Paper jam of a sheet of paper left at the duplex transport section results, if the ADU paper passage sensor/2 (PS48) is turned from OFF (blocked) to ON (unblocked). | |
