2-82 Service Manual
Duplex option service check
Messages displayed when a 23x Duplex Paper Jam displays.
If sheets have been accumulated to be stapled or offset when the jam is detected, the printer alternately flashes
the primary and secondary messages to indicate that all accumulated sheets should not be removed during the
jam clearance procedure. Obviously, if no sheets have accumulated for stapling, then no message flashing
occurs and the primary message is used.
When the secondary message is posted, if accumulated sheets are removed during jam clearance, the printer
does not reprint the removed sheets. Furthermore, after the printer resumes printing and the print job is
completed, the portion of the job printed after the jam is not stapled.
