Replaced Count (Unit2) to Replaced Count (Unit5) are used by the

Table 5-202
After changing the value, select the [Set]
button or [All Set] button at the right side of
each item to apply the changed value.
To close the screen, select [Close].
These values are changed when the
control PCB is replaced. After the replacing
the control PCB, the values need to be input.
If you don't know the values before
replacement, you can input estimated
values.
If you replace the control PCB or change
the [Total Count], then the counter for
[Current Rollers] on the user maintenance
screen 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 Rollers] may take on
an invalid value, you should check the
counter for the [Current Rollers] after exiting
service mode and reset it if it is invalid.
Note: The count for the current rollers is the
value that subtracted the total sheet
fed count at the last reset from the
current total sheet fed count.
