Safety Information
To prevent accidents during a maintenance procedure, strictly observe the Warnings and Cautions and never depart from the instructions given in this document. Do not do anything that is dangerous even if not specifically described in this manual.
In addition to the descriptions below and those given in this manual, there are many situations and circumstances that are dangerous. Be aware of these when you are working with the printer.
Power Supply
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 when the power is applied, be aware of the potential for electrical shock and do all tasks by following the procedures in this manual.
WARNING Do not touch any live part unless you are instructed to do so by a service procedure. The power supply switch/inlet part (MAIN POWER SWITCH & INLET) is live even when the power switch has been turned off. Do not touch any live part.
Mechanical Components
If you service a driving assembly (e.g., gears), first turn off the power and unplug the power cord. Then manually rotate the assembly.
WARNING Do not touch the driving part (e.g., gears) while the assembly (printer) is being driven.
GN006EA
GN005EA
Safety Components
The printer is equipped with safety components (e.g., interlock switches, fuses, thermostat) and safety switches for protecting users and service personnel from injury and the equipment from damage. Never handle the printer in such a way that the normal functioning of the safety components is disturbed.
The major safety devices which this printer is equipped with are the following three interlock switches:
FRONT COVER OPEN SENSOR
When the Front Cover opens, the FRONT COVER OPEN SENSOR turns off to cut off +5VDC supplied to each color LDD PWB of the ROS.
INTERLOCK SWITCH
When the Left Cover of the printer main unit opens, the INTERLOCK SWITCH turns off to cut off +24VDC supplied to the DRIVE ASSY MAIN, HVPS, GATE SOLENOID and DUPLEX PWB.
LH COVER INTL SW
When the Left Cover of any additional tray opens, the LH COVER INTL SW turns off.
INTERLOCK SWITCH |
FRONT COVER OPEN SENSOR |
LH COVER INTL SW (Tray Module)
Laser Beam
The printer has an interlock switch (FRONT COVER OPEN SENSOR) to prevent exposure to a laser beam from the laser beam output unit (ROS ASSY). This switch turns off when the Front Cover opens. (For details of the switch, refer to the “Safety Components” in the previous section.)
During your maintenance work, never turn on this switch forcibly by other than ordinary operation since doing so may cause the laser beam to be emitted.
WARNING |
Exposure of your eyes to a laser beam may lead to |
|
blindness. |
|
Never open the Cover where the Warning Label About |
|
Laser Beam is affixed. |
|
If you disassemble or assemble the printer, turn off the |
|
power. |
|
If you need to work on the printer with power applied, |
|
strictly follow the instructions in this manual. |
|
Understand how the laser beam functions and take |
|
maximum precautions not to injure yourself or anyone |
|
around you. |
CHECK |
The laser beam has a narrower frequency band and more |
POINT |
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. |
|
Therefore, a laser beam is harmful to the human body. |
|
The laser beam in this printer is invisible. |
Warning Label
(Refer to “Warning Label About Laser Beam”)
ROS ASSY
High Temperature Assembly
To prevent you from becoming injured or burned, do the following: Before working with a high temperature assembly (e.g., Fuser unit), be sure to turn off the power, unplug the power cord and wait until it cools down adequately.
CAUTION The high temperature assembly is very hot immediately after any printer operation. Wait at least 20 ~ 30 minutes,
until the printer cools down adequately.
Caution Label
(Refer to “Caution Label About High-temperature Surface”)
Fuser unit
GN004EA
Ozone
Because of the printing principle of laser printers, this machine emits a very small amount of ozone in the process of printing. (The exhaust air may smell of ozone.) This printer generates only a very small amount of ozone that never exceeds the safety permissible value (0.1 ppm / 0.2 mg/m3) in the normal work environment. Avoid operating the printer under any of the following conditions:
Any ambient conditions other than specified for use of this printer Use of two or more laser printers in a small room
Use in a place where sufficient ventilation is not available
Especially, continuous operation for an extended period of time under any of the above-mentioned conditions
Warning/Caution Labels
Warning labels and caution labels are affixed to this printer for accident prevention.
CHECK |
In maintenance work, check that the labels are free from |
POINT |
peeling and soiling. |
|
|
Warning Label About Laser Beam
Stuck on the top of the laser beam emitting unit (ROS ASSY) to warn the maintenance personnel of danger of exposure to the laser beam.
(Refer to “Laser Beam”)
Caution Label About High-temperature Surface
Stuck on the side wall of the Fuser unit, which becomes hot, in order to warn the user of danger of suffering a burn.
(Refer to “High Temperature Assembly”)
Warning Label About Toner
Stuck on the Waste toner collector and Toner Cartridge to prevent dust explosion caused by toner. This Warning Label prohibits you from throwing toner into fire.
Parts
To prevent you from becoming injured, keep the following in mind:
When handling a heavy part (device included), pay careful enough attention to your working posture to prevent back pain.
CAUTION Handle a heavy part with extreme care. Handling it in an inadvertent posture may put a load on your back or cause
you to drop the part.
Be careful not to injure yourself with the sharp edges of the parts.
Do not work with wet or oily hands-you may drop a part or injure yourself. Dry your hands first.
When pulling out a part (including a harness), do not use too much force. Pull out the part carefully and slowly step by step.
Consumables
Understand the following explanation and handle the consumables carefully.
Some parts may cause a particulate explosion or fire if handled improperly. Do not handle these parts near fire or throw into a fire.
Some materials, especially toner, may cause bodily injury. Do not swallow or inhale such materials or allow them to come in contact with the eyes. Help to protect those around you and follow the prohibitions against swallowing or inhaling such materials. Be careful to protect the eyes at all times.
Place a sheet inside or under the printer so that the floor or workbench is protected.
If the Developer or Fuser Oil gets on your clothing, dry it with a cloth and wash with clean water.
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.)
WARNING Do not pick up dropped toner with a general vacuum cleaner. To do so may cause ignition.

Improper Printer Use
Modifying, revising, tampering with the printer, especially to the safety mechanism, is strictly prohibited in all circumstances.

Other Precautions
Paper Storage
When paper is not loaded in the printer, enclose it in a packing material or put it in a plastic or similar bag to prevent dehumidification/moisture absorption in order to optimize print images.
Opening and Closing of LH ASSY during Work
If you have opened and closed the LH ASSY with the printer off, always power on the printer after closing the LH ASSY to warm it up, and then finish your work.
If you do not warm up the printer, the BTR Drive Gear is left in improper engagement and the BTR Roll will be deformed, affecting the print quality.

PRINTING SPEED MODE |
|
Full speed mode |
: Prints at the fastest speed of the main unit when |
|
printing plain paper, recycled paper, and fine paper. |
Low speed mode |
: Feeds paper at reduced speed to prevent loss of |

PRINTING MODE BY PAPER TYPE
The main unit has 24 modes for the various media. Modes are switched by instructions from the controller. The engine determines the combination of modes corresponding to simplex/duplex printing and the media, and sets the process speed to one of 2 levels, full speed and low speed, as shown in the following table.
