(7) Choice of securing fusibility
• Sets whether or not to conduct printing wait for ensuring fusibility in low-temperature/low-humidity environments.

ON
(8) Choice of unit simultaneous replacement promotion
• To set whether or not to enable "Controlling printing prohibition of life values."
Switch No. 14
OFF
ON
(9) Choice of main scan direction white line correction
• When printing is continued with lower coverage, filming may occur to the transfer belt which may cause the main scan direction white
lines.
• By setting this ON, the toner will be supplied to the transfer belt by the toner patch during image stabilization to prevent white lines to
occur.
• The toner consumption increases by using this setting. Choose the setting suitable for the user.

NOTE
▪ To reflect the adjustment value after change, make sure to exit from the Service Mode.
▪ The adjustment value is not reflected when turning off the power without exiting from the Service Mode.
(10) Transfer belt free rotation option
• Rotates the transfer belt under predetermined conditions to prevent whiteouts and black lines that develop when the machine has not
been used for long time.
Switch No.23
OFF
ON
NOTE
▪ To reflect the adjustment value after change, make sure to exit from the Service Mode.
▪ The adjustment value is not reflected when turning off the power without exiting from the Service Mode.
(11) Choice of ACS parameter
• It sets the black printing quantity threshold until switching the transfer belt from all press to K press when a few pages of black printing is
included in color printing.
• With the initial setting, print productivity has the priority and printing is conducted with all press (the transfer belt being pressed onto the
color photoconductors) even when the specified quantity of black printing is included. In that case, the color photoconductors rotate
unnecessarily. The color photoconductors deteriorate by the amount of rotation.
• When this setting is ON, black printing quantity threshold until switching to K press (release of color photoconductors) becomes smaller.
• This setting is to be used when the degradation control of the color photoconductors should have priority over printing productivity.
