Maintenance
The LaserWriter 12/640 PS is designed for trouble-free service. Maintenance
involves little more than putting in a new toner cartridge every 6,000 pages
or so and performing a few minor cleaning tasks. The recommended service
interval is 120,000 pages to check and service wear on the rollers and fuser.
This service can be arranged through an Apple-authorized dealer.
