Retrofit Information
The following platinum corona wires have been registered as service parts. The tungsten
corona wires are currently being installed on the assembly line, but they may be replaced
in the field with the platinum corona wires, if desired.

Description Current Tungsten Corona P/N
FROM:Copier Technical Support Section
MODEL: F20
The platinum and the tungsten corona wires are fairly similar in performance and handling;
however, there are the following differences:
Point 1
During the copy cycle, less foreign matter (toner, dust, gas) will build up on the surface of
a platinum corona wire than on a tungsten wire. Consequently, platinum corona wires do
not need to be cleaned as often to maintain copy quality. This is true for both these
platinum corona wires and the third vendor’s platinum corona wires.
Point 2
Negative charges cause portions of the surface of a platinum corona wire to break off,
affecting the copy image and requiring replacement of the wire. A platinum wire cannot be
used as a negative charge corona. (A tungsten wire can be used as a negative charge
corona wire.) This is true for both these platinum corona wires and the third vendor’s
platinum corona wires.

--When to install the platinum corona wires-
The platinum corona wires do not have to be cleaned as often as the tungsten wires
(point 1). For this reason, the platinum corona wires are most suitable in cases where a
machine is installed in a relatively inaccessible location (far from a service center) and
service calls are difficult to make.
The platinum wires can be installed in the field on the following models:

When installing the platinum corona wires, please take the following actions:
1. Clean the corona casings, end blocks, and new platinum wires with damp cloth.
2. Confirm VSG.
Note 2
#A0079540 can also be used as the F90 main corona wire.

Retrofit Information
This RTB clarifies installation of the sorter, sorter stapler, and connector units on the F20,
F21, and F22. Both 20bin and 40 bin systems are covered.
Because the F20, F21, and F22 copy at different speeds, the main PCB ROM on the old
sorter or sorter stapler must be replaced on some types of systems. Therefore, please
read this RTB carefully for F20/F21/F22 system installation.
