CAUTION
This product is a class 1 laser product that complies with 21CFR 1040.10 and 1040.11 of the CDRH standard and IEC825. This
means that this machine does not produce hazardous laser radiation. The use of controls, adjustments or performance of
procedures other than those specified herein may result in hazardous radiation exposure.
This laser radiation is not a danger to the skin, but when an exact focusing of the laser beam is achieved on the eye’s retina, there
is the danger of spot damage to the retina.
The following cautions must be observed to avoid exposure of the laser beam to your eyes at the time of servicing.
1) When a problem in the laser optical unit has occurred, the whole optical unit must be exchanged as a unit, not as individual
parts.
2) Do not look into the machine with the main switch turned on after removing the developer unit, toner cartridge, and drum
cartridge.
3) Do not look into the laser beam exposure slit of the laser optical unit with the connector connected when removing and
installing the optical system.
4) The middle frame contains the safety interlock switch.
Do not defeat the safety interlock by inserting wedges or other items into the switch slot.

1. GENERAL
1.1 Main features
The d-Copia 12 copier has the following major
characteristics:
-High-speed laser copying
· Since warm-up time is zero, copying can be started
immediately after the power switch is turned on.
· First-copy time is only 9.6 seconds (normal mode).
· Copying speed is 12 copies/min. which adapts to busi-
ness use, allowing improvement of working efficiency.
-Digital high-quality image
· High-quality image copying with 600 dpi can be per-
formed.
· In addition to the automatic exposure mode, the manual
exposure can be adjusted in five steps.
· The photo mode copying function which allows clear
copying of delicate halftone original images such as
monochrome photos and color photos can be used.
-Substancial copying functions
· Zoom copying from 50% to 200% in 1% increments can
be performed.
· A maximum of 99 copies can be selected.
· Toner save mode for reducing toner consumption by
approximately 10% can be set.
-Environmentally friendly design
· Paper output tray is housed in the copier for space
saving.
· Preheat mode and auto power shut-off mode are provid-
ed to reduce power consumption in standby mode.
-Printer feature
· This copier is also a laser printer.

2. UNPACKING AND
INSTALLATION
2.1 Copier installation
Improper installation may damage the copier. Please
note the following during initial installation and whenever
the copier is moved.
Caution: If the copier is moved from a cool place to a
warm place, condensation may form inside the
copier. Operation in this condition will cause
poor copy quality and malfunctions. Leave the
copier at room temperature for at least 2 hours
before use.
Do not install your copier in areas that are:
• damp, humid, or very dusty
• exposed to direct sunlight
• poorly ventilated
• subject to extreme temperature or humidity
changes, e.g., near an air conditioner or heater.
The copier should be installed near an accessible
power outlet for easy connection. Be sure to connect the
power cord only to a power outlet that meets the specified
voltage and current requirements. Also make certain the
outlet is properly grounded.
Be sure to allow the required space around the machi-
ne for servicing and proper ventilation.
2.2 Cautions on handling
Be careful in handling the copier as follows to maintain the
performance of this copier.
Do not drop the copier, subject it to shock or strike it
against any object.
Do not expose the drum cartridge to direct sunlight.
Doing so will damage the surface (green portion) of the
drum cartridge, causing poor print quality.
Store spare supplies such as drum cartridges and TD
cartridges in a dark place without removing from the package
before use.
If they are exposed to direct sunlight, poor print quality
may result.
Do not touch the surface (green portion) of the drum
cartridge.
Doing so will damage the surface of the cartridge, cau-
sing poor print quality.
