Laser Printer Service Manual

magicolor 330 - Base Engine Service Manual 1-3

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

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 these directions:

• Before starting any service procedure, switch off the printer power and unplug the power cord from the wall

outlet.

• Do not disassemble the ROS Assembly or any laser component that displays a Laser Warning Sticker.

• Use caution when you are working around the ROS Assembly or when you are performing laser related trou-

bleshooting or repair procedures.

• Do not disassemble the printer in such a way that the laser beam can exit the print engine during a print cycle.

Fuser Components

This printer uses heat to fuse the toner image to a sheet paper. The Fuser Assembly is very

hot. Switch off printer power and wait at least 45 minutes for the Fuser to cool before you

attempt to service the Fuser Assembly or adjacent components.

Safety Components

Make sure interlock switches, covers, and panels are all functioning properly after you have reinstalled or replaced

them. If you bypass an interlock switch use extreme caution when working on or around the printer.

Warning Labels

Throughout the printer, warning labels are displayed on potentially dangerous components. When you service the

printer, check to make sure that all warning labels are in place.

Most importantly, read and obey all posted warning messages.
