发明名称 Image forming apparatus with sheet jam detection
摘要 An image forming apparatus includes an image forming unit which has a rotating photoconductor, and a transfer unit disposed adjacent the photoconductor which retains an image-formation sheet on its circumferential surface. It further includes a sheet feeding path for feeding a sheet to the transfer unit, a sheet discharging path for discharging a sheet from the transfer unit, a first sensor for detecting a jammed-sheet condition in the sheet feeding path, a second sensor for detecting a jammed-sheet condition in the sheet discharging path, and assume function which assumes a paper jam in the transfer unit in conjunction with the determination of the first detecting sensor and/or the second detecting sensor. Accordingly, the apparatus does not neglect to cope with a sheet remaining on the transfer unit under a halt condition due to the sheet-jam. Thus obstruction to a following copying operation by a sheet remaining on the transfer unit is averted after the jammed-sheet condition is remedied.
