21) Developer Roller Counter Reset 3 (For the 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. At that time, the developing 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.
