Laser Components This printer generates a laser beam as part of the printing process. The laser beam is a con- centrated narrow beam of light that produces extreme heat at its focal point. The laser WARNING beam in this printer is invisible. Although you cannot see the beam, it can still cause severe damage. Direct eye exposure to the laser beam may cause eye injury or blindness. Never place a mirror or a reflective tool or object in the laser beam path. To avoid permanent eye damage, follow the

Fault Isolation Procedures General Notes on Using FIPs 1. FIPs assume there is no malfunction in the printer Controller (ESS). If you are unable to fix a problem using the FIPS, we recommend that you replace the printer Controller. 2. FIPs frequently use new or "known good" components as troubleshooting tools. We recommend you carry a spare Fuser Assembly, MCU PWB, Controller PWB, LVPS, and Xerographic Cartridge. 3. Unless indicated otherwise, the instruction "switch ON printer main power" means
