FEDERAL COMMUNICATIONS COMMISSION NOTICE

This equipment has been tested and found to comply with the limits set for a Class B digital device, as

stated in Part 15 of the FCC rules. These limits are designed to provide reasonable protection against

harmful interference in a commercial installation. This equipment generates, uses, and can radiate radio

frequency energy. If not installed and used in accordance with the instructions provided, this equipment

may cause disruptive interference to nearby radio and television communications. Even if the equipment

is installed according to the instructions, there is no guarantee that interference will not occur in a par-

ticular installation. If this equipment does cause disruptive interference to nearby radio and television

reception, switch the equipment off to determine if it is the true cause of the interference. If the equip-

ment is the cause of the interference, the user should try to minimize the interference by using one or

more of the following actions:

• Either re–orient or relocate the radio/television receiving antenna.

• Increase the separation between the equipment and the radio/television receiver.

• Connect the equipment to an AC outlet that is not on the same circuit as the radio/television

receiver.

• If the previous solutions fail to bring results, you should consult either your equipment dealer or an

experienced radio/television technician.

For more information on interference, refer to the Federal Communications Commission’s booklet “How

to Identify and Resolve Radio-TV Interference Problems”. This booklet is available from the U.S. Gov-

ernment Printing Office, Washington D.C. 20402, Stock No. 004-000-00345-4.

CLASS 1 LASER PRODUCT

This Laser Printer is certified to comply with the Class 1 laser product performance standards as set by

the U.S. Department of Health and Human Services. This class of laser product has an enclosed laser

system that keeps all laser energy safely inside the fully assembled and closed printer.

The laser and output of the laser scanning unit produce a beam that, if viewed, could cause serious eye

damage. Service procedures must be followed exactly as written. Use of controls, adjustments, or proce-

dures other than those specified in this manual may result in exposure to hazardous laser radiation.

Safety information

Follow all safety instructions to prevent accidents while servicing this laser printer. Always be aware of the potential

dangers that are present when you are working with electrical or mechanical equipment.

Power supply and electrical components

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

you must service the printer with power applied, be aware of the potential for electrical shock.

Do not touch any electrified component unless you are instructed to do so by a service pro-

assemblies while any printer motor is running.

WARNING

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.
