This corresponds to "pages since last maintenance" on the configuration page. Editing this number is similar to editing the PAGES item (see table 24). If the printer has not reached the first maintenance interval (for example, 150,000 pages), then set the maintenance count equal to the page count. The maintenance page count should be reset only after a maintenance kit has been installed. This resets the maintenance counter so that the message PERFORM PRINTER MAINTENANCE appears after another 150,000 pages have been printed (default).
Hold down the [-ITEM] and [-VALUE] keys.
Turn the printer on.
Wait for RESET MAINT COUNT to appear and then release both keys. MAINTENANCE INTERVAL in the service mode menu sets the page count interval at which the next service is due for the printer. This is set initially at the factory to 150,000 pages. (For example, the message appears at 150,000 pages. If the printer maintenance kit is installed at, and the counter is set to, 150,114 pages, then the message appears 150,000 pages later, at 300,114 pages.) Editing this number is similar to editing the PAGES item (see table 24). Serial number If a formatter is replaced, then the serial number must be recorded. Editing this number is similar to editing the PAGES item (see table 24). Chapter 3 Printer operation 61
