The “Reset Roller Count” button：
After scanning over a recommended number of pages (refer to
subsequent section 7.4 Replacing the ADF Roller) through the
ADF, the ADF roller may be worn out and you may experience
problems with document feeding. In this case, it is highly
recommended to replace the ADF roller with a new one. (Note
the replacement of the ADF roller has to be performed only by
authorized service center. Therefore, please return your
scanner for roller replacement.) After replacing the ADF roller,
click the “Reset Roller Count” button to reset the roller count.
Note：
The lifetime and the replacing procedure vary based on type of
scanner.
