Setting the Page Count

The printer page count can be changed using the Diagnostics menus. This menu is used
by the CE to reset the Page Count setting whenever the engine card is replaced. The
engine card contains the printer NVRAM memory. When Page Count is selected from the
PRINTER SETUP menu, the current page count is displayed:
Page Count
=1234567*
The leftmost digit ('1' in this example) blinks, indicating it is the first digit to be changed. To
change the value, press Menu until the value you want is displayed. Press Select to
move to the next digit. The next digit ('2' in this example) blinks. Continue modifying each
digit using this method. To skip a digit (that is and keep its current value), press Select.
