    Maintenance EPL-3000 /ActionLaser 13(UI Service Manual 6.1 MAINTENANCE The EPL-3000 and ActionLaser 1300 are page printers that use an electrophotographic printing method. Unlike most impact or ink-jet printers, the key components in the electrographic process are integrated into an expendable cartridge (the imaging cartridge). Therefore, periodic replacement of the imaging cartridge is essential to ensure high-quality output.
