3-34 Printer Operation
Page Count
The page count stored in NVRAM and displayed on the Configuration
Page printout represents the number of pages which the printer has
printed (excluding engine test prints). If it becomes necessary to
repair a printer by installing a new Formatter, the page count must be
reset so that it represents the age of the printer’s engine rather than
the age of the Formatter.
The page count value is changed using a different method than is
used for other Control Panel values. Instead of increasing the entire
value by increments, each digit can be selected and modified
individually. The following Control Panel keys are used to modify the
page count value:
Table 3-14 shows the sequence of keystrokes used to change the
page count from a value of 000000 to a value of 0010480.
[Select] Enters any changes to the current digit and advances the
cursor one digit to the right. If the last digit is currently
selected, pressing the [Select] key wraps the cursor
around to the first digit.
[Value +] Increases the value of the currently selected digit by one.
Pressing [Value +] when 9 is the value of the currently
selected digit will change the value of the digit to 0.
[– Value] Decreases the value of the currently selected digit by one.
Pressing [– Value] when 0 is the value of the currently
selected digit will change the value of the digit to 9.
