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.
