Safety Information

To prevent possible accidents during maintenance work, strictly observe the WARNINGs and CAUTIONs described in this manual. Never attempt to perform dangerous operations or any other operations which depart from the descriptions and procedures in this manual. Other than the cautions and warnings stated below, there are many other situations and circumstances that could result in serious bodily injury . Always pay enough attention to secure safety when working with the printer.

Power Supply

Before starting any service procedure, turn the printer power off and unpl u g the power cord from the wall outlet.When the power supply cable must b e connected, b e aware of the potential for electrical shock and do all tasks by following the procedures in this manual.

W A R N I N G

 Do not touch any live parts other than the required parts while

the printer is on.

 As the LVPS ASSY (power supply section) is live even when the

power is off, never touch the live parts.

 Do not touch any live parts unless instructed to do so.

Mechanical Components

When servicing any driving assembly (e.g., gears), first turn the power off and unplug the power cord, and then manually rotate the assembly.

W A R N I N G

Do not touch the driving part (e.g., gears) while the as sembly (printer) is operating.

High Temperature Assembly

When working with hot parts (FUSER etc.) make sure to turn the power off, unplug the power cable, and leave the printer until it cools down sufficiently to work with to prevent burn injury.

W A R N I N G

As the inside of the printer is high-temperature state immediately after the operation, leave it more than 40 minutes before working.

Laser Beam

W A R N I N G

C H E C K

P O I N T

 Letting a laser beam get directly into your eyes could result in

loss of vision.

 Never open the Cover where the Warning Label about Laser

Beam is affixed.

 Before disassembling or assembling, be sure to turn the power

off.

 If you need to work on the printer with power applied, strictly

follow the instructions in this manual.

 Und erstand hazardous nature of the laser beam, use extreme

caution to avo i d i n jury of yoursel f and anyone around you.

 Sin ce the laser beam has a narrower frequency band and more

coherent phases than any other light (sunlight, electric light), the beam has excellent monochromaticity and convergence, thus it reaches long distances.

 Because of these characteristics, the laser beam converges into

one point, causing high density and high temperature, which is harmful to the human body.

Reference: The laser beam in this printer is invisible.

Cautions relating to Toner cleaning

Storage of Paper

 To prevent ignition, explosion, burn, injury, etc., do not use a general vacuum

cleaner for cleaning dropped toner. (To do so may cause the toner to catch fire by sparks in the vacuum cleaner.)

W A R N I N G

Do not pick up dropped toner with a general vacuum cleaner. To do so may cause ignition .

Damp papers could cause printing quality troubles. To keep papers in their best condition, store them wrapping tightly with packing material or putting them into a plastic bag.
