Step before Replacement
Select “List Output” from the Service Mode Menu and produce the following lists: “Image
Processing” and “Counter.”
NOTE
Check the settings of the following functions and make a note of them before replacement,
as no lists will be produced for them.
Setting 1: CH Cleaning, A6 Card Margin (4 × 6 Paper Margin)
Setting 2: Paper Kind, Admin. Mode, RD Mode, Orig. Detect Sensor
Machine Adjust 1: Fuser Temp.
In addition, the settings in the User’s Choice of Utility are not printed. Check and make a
note of these settings, too, as may be necessary.
Steps after Replacement
1. Clean the optical parts (PH Assy, Original Glass, lens, mirrors, Lamp).
2. Add fuser oil up to the required level.
3. Replace the Toner Collecting Box with an empty one, or dump toner from the Toner Collecting Box.
4. Remove the Rear Cover to prevent predrive from being initiated.
NOTE
Since the new Backup Memory RAM has no old developer data, the copier may detect a
malfunction as it relates to the Developing Unit if predrive is initiated.
5. Using Touch Panel Correct, correct the position of the keys on the Touch Panel.
6. On the list of “Life 3 (Others)” available from “Counter” of the Service Mode Menu,
select “Toner Collect” and press the Clear key.
7. Since the Touch Panel language is English, select “Language” of “User’s Choice” available from Utility and change the setting as necessary.
8. Select “Marketing Area” of “Setting 2” available from Service Mode Menu and select the
same marketing area as that before the replacement.

(3)Writing upon Replacement of IR Control Board/Master Board
• If the IR Control Board or the Master Board is replaced individually, load the memory
card in the board that has been replaced for data writing.
• If both the IR Control Board and the Master Board are replaced at the same time and if a
single memory card is to be used, start writing the data with the Master Board side.
The copier does not rewrite data if an attempt is made to write data first for the IR Control
Board.
(4)Action to be Taken When Data Transfer Fails
When the message “Engine: N.G” or “IR: N.G” appears on the Touch Panel, it indicates that
data has not been properly rewritten. In this case, perform the following steps.
If two memory cards have been used, only the specific board with which data transfer failed
is displayed.
1. Perform the data rewriting procedures again according to the above steps.
2. If the sequence is not normally terminated, change the memory card for a new one and
try another rewriting sequence.
3. If the sequence still fails, replace the Master Board or IR Control Board and then try
another rewriting sequence.
If the message “Engine: N.G” appears, replace the Master Board.
If the message “IR: N.G” appears, replace the IR Control Board.
