HP LaserJet 5000 Service Manual - Page 77

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: [Select] [Value+] [-Value] 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. 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. 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. Table 3-12 shows the sequence of keystrokes used to change the page count from a value of 000000 to a value of 0010480. 3-32 Printer Operation EN
