Perfect Binding
Perfect binding is a binding method that applies heated glue to printed sheets to form a book block, encloses the book block in a cover sheet, and trims away excess paper to create neat edges.
You can specify the perfect binding settings using the display panel or the printer driver.
To specify the settings using the display panel, see "Basic Copying", Copy and Document Server Reference.
To specify the settings using the printer driver, see the printer driver Help.
Book blocks must be loaded in the
orientation, and cover sheets must be loaded in 
orientation. For details, see About This Machine.If the machine is being used for perfect binding, some functions might not be available. If another job cannot be performed on the machine, wait until the perfect binding job is complete, and then try again.
When specifying perfect binding, make sure that the number of printed sheets is not smaller than 10.
Perfect binding is possible within the following limitations:
Book block size
10 - 200 sheets (paper weight: 64 - 80 g/m2, 17 lb. Bond - 20 lb. Bond)
10 - 150 sheets (paper weight: 81 - 105 g/m2, 20 lb. Bond - 28 lb. Bond)
10 sheets (paper weight: 106 - 163 g/m2, 28 lb. Bond - 90 lb. Index, slip sheets only)
Book block paper type
Plain Paper, Middle Thick Paper, Color 1, Color 2, Yellow, Green, Blue, Purple, Ivory, Orange, Pink, Red, Gray, Special, Letterhead, Preprinted, Coated
Spine thickness
Up to 23 mm (0.9 inch)
If the spine of the book block exceeds maximum thickness (23 mm) during binding, the machine stops. Printed sheets are left inside the binder and must be removed by hand.
Perfect bound booklets are delivered to the lower left tray. Up to seven booklets (of 100-sheet book blocks) can be stacked on the tray.
The glue requires time to heat (six and a half minutes maximum) before binding can begin. To begin binding quickly, be sure to press the glue temperature adjustment key in advance.
Printing cannot start while the glue temperature adjustment key is unlit or flashing.
If you press the delivery key before binding finishes (before the status indicator goes off), the lower left tray will not open. Press the delivery key during binding (while the status indicator is blinking) to set the tray to open automatically when binding finishes.
While “Perfect Binder Lower Left Tray is full. Remove the paper.” is displayed, you cannot perform perfect binding. Remove booklets from the lower left tray.
When removing booklets, be sure to clear the lower left tray completely. You cannot perform perfect binding if there are booklets remaining in this tray.
Do not print anything on the inner side of the cover sheet (the area glued to the book block). Doing so can prevent the cover sheet and book block from adhering properly.
If you open and close the front right or front left cover to remove jammed paper, binding will be suspended. To resume binding, close the front covers and wait a few minutes. Binding will restart automatically.
If a misfeed occurs during perfect binding, you cannot open the front right and front left covers. Wait until the bound booklet is delivered to the lower left tray, and then open the covers.
Waste paper produced during perfect binding might collect around the lower left tray. If this happens, clean the area when removing booklets from the lower left tray.
