6.9.2 DEVELOPMENT UNIT
Replacing Units
Recovery: Each new development unit spare part contains a starter toner cartridge.
When the machine detects the memory chip on the new starter cartridge, it will
clear the development unit end condition. The memory chip on a normal toner
cartridge cannot clear the development unit end condition.
A starter toner cartridge has more paddles on the toner cartridge agitators than a
normal toner cartridge does. This is to transport toner more quickly from the
cartridge into the toner hopper.
When a development unit has to be replaced, use a starter toner cartridge in the
development unit even if toner remains in the used normal toner cartridge. After the
toner in the starter toner cartridge is all used up, the normal toner cartridge can be
loaded into the development unit.
Memory Chip
Each toner cartridge contains a memory chip, which contains information on
whether the cartridge is “new” or “not new”.
