• Selectors 5 and 6: Assurance print 1 and 2
Enabling assurance print 1 or 2 causes the machine to mix black ink (pigment-
based) and a little of cyan ink (dye-based) to use in monochrome copy or in
monochrome FAX reception and list output, respectively.
If black ink is not jetted out normally, cyan ink can be substituted for black ink in
printing. This ensures that in list printing (in which data once printed will be
deleted) the data will be preserved as a printout.
• Selectors 7 and 8: Workaround for false jam detection (Functional restriction on the paper width
sensor)
The setting made by these selectors applies to the FAX, list, index printing and test
printing.
When colored recording paper is used, for example, the paper width sensor might
misdetect the paper present state as "no paper loaded" due to the recording
paper's color. Limiting the paper width sensor functions with these selectors avoids
detecting such a false paper jam.

• Selector 6: Registration time offset to slipping in plain paper feeding
Enabling the registration time offset with this selector increases the registration
time (during which the paper feed roller rotates in the reverse direction), avoiding
the occurrence of a paper feeding timeout error even if the paper cannot reach the
registration sensor actuator within the predetermined registration time due to
slipping of the paper pull-in rollers against paper in the paper tray.
Selecting the "Fast" print quality disables the registration time offset even if it is
enabled with this selector.
Note: Selecting the "Glossy paper" automatically enables the registration time
offset.
