1-3-1 Paper misfeed detection
(1) Paper misfeed indication
When paper jams, the machine immediately stops operation and the occurrence of a paper jam is indicated on the copier
operation panel.
To remove the jammed paper, lower the intermediate tray or open the duplex unit.
To reset the paper misfeed detection, detach and refit the intermediate tray to turn the tray open/close switch off and on or
open and close the duplex unit to turn the duplex open/close switch off and on.
