Contents
| JAM type | Misfeed at ADF section |
| Detection timing | The original does not block the paper interval sensor (PS103) even after the lapse of a given period of time after the original feed is started. |
| The original does not block the registration sensor (REYB100) even after the lapse of a given period of time after the original blocks the paper interval sensor (PS103). | |
| The duration between the original's blocking and unblocking of the paper interval sensor (PS103) is shorter than a given period of time. | |
| When the preceding page of the original blocks and then unblocks the registration sensor (REYB1009), the subsequent page of the original does not block the paper interval sensor (PS103). | |
| The original does not block the registration sensor (REYB100) even after the lapse of a given period of time after the original is fed again. | |
| The original does not block the before read sensor (REYB101) even after the lapse of a given period of time after the original blocked the registration sensor (REYB100). | |
| The original blocks the before read sensor (REYB101) longer than a given period of time. | |
| When the power switch is turned ON, the registration sensor (REYB100), before read sensor (REYB101), or paper interval sensor (PS103) is blocked. | |
