6.1  Overview
This section gives information necessary for maintaining the printer in its optimum 
condition.
In maintenance and checks, never fail to observe the following precautions.
W A R N I N G
 To prevent an electric shock, burn, injury, etc., always turn 
the printer off and unplug it from power outlet before 
starting maintenance work.
When the power supply cable must be connected to measure 
voltage or for any other task, use extreme caution in working 
on electronic components.
 While the printer is operating, never inspect the drive areas 
such as the motor, sprockets and gears.
 Weight: Since this printer is heavy (about 25kg,
consumables not included), it should be moved by two or 
more people and lift it with your legs not with your back.
 Safety devices: Special care must be taken to maintain safety 
devices such as fuse, INTERLOCK S/W, which are provided 
to prevent the printer from malfunction and accidents, and 
also carefully check the parts such as panel, covers, which are 
directly operated by the user. 
 Immediately after the printer has stopped operating, do not 
touch the FUSER ASSY (Fuser unit) as it is hot.
 Pay attention to the following when turning the printer back 
on after servicing. 
• Be careful not to get your hands and clothes caught up in 
the rotating parts (various rollers and cooling fans) of the 
printer.
• Never touch the electrical terminals and high-voltage 
components. (HVPS or LVPS unit, etc.)
 To avoid dust explosion or ignition, never bring any 
consumables close to flame or throw them into fire.
W A R N I N G
 Take extra care not to let the laser beam get into your eye, or 
it could cause loss of sight.
 While servicing the laser printer, never open any cover on 
which a Warning Label for Laser beam is attached.
 Use extreme caution to avoid injury of yourself and anyone 
around you with a clear understanding of hazardous nature 
of the laser beam. 
 When you need to work on the hot part or unit (Fuser Assy, 
for example), make sure to unplug the printer from power 
outlet in advance. And do not start the work basically until 
the part or unit cool down sufficiently to avoid burn injury.
 This printer produces a laser beam when the following 
conditions are all satisfied.
• The printer turns on. 
• The interlock switches are OFF.
 Do not use a general vacuum cleaner to clean spilt toner. To 
do so may cause the sucked toner particles to catch fire by 
sparks of the electric contacts. If the toner has spilt on the 
floor, etc., clean it with a broom or wipe it with a cloth 
moistened with neutral detergent. If it is necessary to clean a 
lot of spilt toner with a cleaner, use a cleaner exclusively 
designed for toner.
