Jams
Handling Paper Jams
What Happens When a Jam Occurs
When a jam occurs open the cover at the jam location, remove the jammed paper and close the cover.
However, the operator should be cautioned about opening the top cover of the bookbinder.
• The top cover should be opened when only absolutely necessary.
• Opening the top cover can disturb paper that is already on the stacking tray.
When a Jam Occurs at Power On
A jam alert will occur at power on if there is paper or a signature in the horizontal paper path, vertical
path, signature path, inserter path, or on the stacking tray. Open the cover at the jam location, remove the
jam, and close the cover. If the signature jams beyond the stacking tray, recovery processing executes
automatically and upstream sheets are output to the stacking tray and stop there. However, if one of the
aforementioned jams occurs in the paper path at power on, recovery processing does not execute until
after the jam has been removed.
Power Loss During Glue Application
If the system is turned off while glue is being applied to a signature:
• The gluing unit begins to warm the glue after the power is turned on.
• After the glue has been warmed up, the glue vat returns to its home position.
• The bookbinder enters recovery mode automatically and paper once again starts exiting the signature
path to the stacking tray.
When an Error Occurs
Low Performance Mode
Cycling the system off/on usually restores the bookbinder to full operation after a jam has been removed.
• If an error occurs and cycling the machine off/on does not solve the problem, then the service
technician must release the grip unit in the service mode, turn the bookbinder off, and then remove
the jam.
