SAFETY INFORMATION

In order to prevent accidents from occurring while maintenance is being carried out, all warnings and precautions should
be strictly observed while work is being carried out. Never attempt any kind of dangerous procedure when servicing this
machine.
The precautions noted below only cover a few of the situations which could foreseeably occur during maintenance
operations. Please make sure every safety precaution is observed while work is being carried out.
2-1. Power Supply
In order to prevent electrical shock, burns, damage to the equipment and other problems, always make sure the power
supply is turned off and the power supply cable has been unplugged before maintenance work is carried out.
If the power must be left on in order to measure voltage or for other reasons, make sure sufficient precautions are taken
to prevent electrical shock, and follow the procedures laid down in this manual.
2-2. Drive Parts
Inspection of drive section parts such as sprockets and gears should be carried out using a hand crank.
DANGER: Never inspect these parts while the equipment is in operation!
2-3. Safety Devices
Thorough consideration should be given to safety devices designed to prevent accidents (fuses, interlock switches, etc.)
as well as those handled by the user in the course of operating the equipment (covers, panels, etc.), in order to make sure
they fulfill their function as safety equipment.
DANGER: In order to prevent exposure to the laser beam contained in the printer, the following precautions must
always be strictly observed.
Exposure to the laser beam can result in blindness.
• Never open a cover (ROS assembly) that has the label shown in figure 1-3 on it.
• When disassembling and adjusting the equipment, always make sure the power supply has been
turned off first.
• This equipment is provided with a two-stage safety switch function, so that it can be operated even
with the covers removed, by pressing the interlock switch. When using this method of operation, never
short the other switch at the same time (the second switch is pressed when the actuator at the back of
the EP toner cartridge attachment section is pressed).
• When servicing the printer's optical system, be careful not to place screwdrivers or other reflective
objects in the path of the laser beam.
Be sure to take off accessories, such as watches and rings, before working on the printer. A reflected
beam, though invisible, can permanently damage your eyes.
Because the laser beam is invisible, be especially careful when servicing the optical system.
