KX-MC6020HX

Case 1) Exchange Service

This service sends the replacement unit to customers first. Then the broken unit is sent to the service center.

1. Install dummy cartridges, which are used for toner leak prevention, before shipping the replacement units.

• This prevents leaking of the waste toner from the accumulator unit.

2. Request customers that install dummy cartridges, preliminarily installed in the replacement unit, to the broken unit and send it

to the service center.

3. Request customers to reinstall currently used toners and drums to the replacement unit.

Caution:

If the broken unit is shipped without dummy cartridges, the waste toner leaks into the inside of the units as shown below so that
it becomes unrepairable.

*Dummy cartridges are provided as Service parts. (P/N: PNZE2MC6020M) (Refer to 

FIXTURES AND TOOLS

 (P.485).)
