DEVELOPMENT
6.9.2 DEVELOPMENT UNIT
Replacing Units
Each new development-unit spare part contains an empty dummy toner cartridge.
The dummy toner cartridge does not have a memory chip.
When you replace the development unit with a new spare part development unit,
the machine cannot detect the toner cartridge because the dummy toner cartridge
does not contain a memory chip. But the toner cartridge in the used development
unit may still be usable. Because of this, remove the dummy toner cartridge from
the new development unit. Then install the toner cartridge from the old
development unit.
After you install the new development unit, do the SP mode for development
initialization (toner supply & process control) (SP3-929-001 to –004: Development
unit Replace).

NOTE: B051 is shown on CMY development units for both models. But the units
are not interchangeable.
Memory chip
Each toner cartridge contains a memory chip, which contains information about
which machine it can be used in. If a toner cartridge for the B051 series is installed
in this machine, the machine will not detect the toner cartridge.
