Retrofit Information
The following is the procedure for judging whether the pressure roller is still usable or
not, by making a black copy.
1. Access SP mode with the steps below.
Press the Clear Modes (C) key, Plus (+) key, Minus (-) key, Clear/Stop key, and
Clear/Stop key (hold down for longer than 3 seconds) in order.
2. Select Lamp Off Mode, using the following steps.
a) Confirm that the "Lead Margin" indicator lights to allow an SP number to be input.
(If the "Lead Margin" indicator does not light, pressthe Function Select key until
it lights.)
b) Select "-51" by pressing the Minus key. ("-51" is the number to select Lamp Off
Mode.)
c) Press the Function Select key until the "Paper Length" indicator lights.
d) Select "1" by pressing the Plus key. ("1" is the number to set Lamp Off Mode.)
e) Press the RF Select key to confirm Lamp Off Mode.
3. To prevent paper misfeed, make some white area at the leading edge, using the
steps below.
a) Press the Function Select key until the "Lead Margin" indicator lights.
b) Continue to press the Plus key until "99 mm" or "4.0 inches" (max. value) is
indicated.
4. Make a copy using a less fusible kind of paper, like film, translucent paper or
thicker plain paper with the vertical grain direction.
Note: Before making a copy, set the fusing temperature setting to the mode which
is one step lower than the proper setting for the particular kind of paper (ex.
If the proper setting is Mode 3, select Mode 2 for this test). (Refer to RTB
No. 005 about the proper settings for some particular types of paper and the
adjustment procedure for non-listed papers.)
5. Scrape some black areas on the copy using a cotton cloth 5 times.
6. Check whether the toner is peeled off on the areas that correspond to the
scratched parts of the pressure roller, and check if white lines or bands appear. If
so, the pressure roller should be replaced.
7. Before turning the main switch off to reset the SP mode, reset "Lamp Off Mode",
"Lead Margin" and "Fusing Temperature Setting" back to the original settings.
