CHAPTER 5 TROUBLESHOOTING
13. Counter
b. Change
This mode is used to display/change
the sheet fed count and the number of
paper jams.
These values are changed when the
control PCB is replaced. After the
replacing the control PCB, input the same
values as before the replacement. If you
don't know the values before the
replacement, input the estimated values.
Note:
Do not change the value of each
item by mistake. Change it only if
necessary.
After changing the value, select the
[Set] button at the right side of each item
to finalize it. Pressing the [Set] button in
the lower right portion of the screen
finalizes values for all items. Note that
[Roller Count] has a [Reset] button instead
of a [Set] button. Click this [Reset] button
to set the value to “0 (zero)”. Do not click
the [Reset] button by mistake because it is
linked to the operation of the [Replace
Rollers] counter for the user.
a. Message
On the service screen, select
[Counter] to display the [Counter] screen.
[Total Count]
Total sheet fed count

[P01 Jam Count]
Number of documents jams in the

[P02 Jam Count]
Number of residual jams
[P03 Jam Count]

If you replace the control PCB or
change the [Total Count], then the counter
for [Replace Rollers] is also updated.
Since the [Replace Rollers] message may
be displayed the next time the user turns
the power on or the counter for the
[Current Roller] may take on an invalid
value, you should check the counter for
the [Current Roller] after exiting service
mode and reset it if necessary.
[Roller Count]
Sheet fed count of the roller being
used (Number of feeds after reset)
