22) Develop Roller Counter Reset (For the starter toner cartridge)
23) Develop Roller Counter Reset (For the standard toner cartridge)
24) Develop Roller Counter Reset (For the high-capacity toner cartridge)
Since print density is likely to become darker as toner is getting older, the developing
bias is lowered by degrees according to the number of prints so that an almost fixed
density can be maintained from the start of the use of brand-new toner to the end of it.
(The value of the developing bias is printed on the Maintenance sheet.) The developing
bias is a parameter which depends on the toner cartridge, so it needs to be reset when
the toner cartridge is replaced. (Usually, it is reset automatically.) At that time, the
develop roller counter reading is also reset. This mode is to enable to execute these
operations (equivalent to those done when the toner cartridge is replaced) manually from
the service mode.

Switch the setting of USB FULL Fixing/Automatic switching (High/FULL). Whenever you

You can verify the setting change by LEDs when releasing the [Go] button. When the
