CHAPTER 1
I. FEATURES
1. High-speed printing
Although compact in design, the Printer is a high-speed printer capable of generating 20 pages per
minute.
2. Various sources of paper with the addition of options
In addition to the cassette and the multifeeder that come as standard, the Printer may be com-
bined with three 250-sheet paper feeders (PF-65; hereafter, paper feeder) to enable 5-way pickup,
each source with different types of paper.
3. Continuous printing of large volumes of work
As many as three option paper feeders may be installed to the Printer. Combined with the stand-
ard cassette and multifeeder, a maximum of about 1,100 sheets of paper (64 g/m2) may be accom-
modated for continuous, large-volume printing work.
4. Power saving, toner saving design
The printer is designed to enter sleep mode (power saving mode) after remaining in standby mode
for a specific period of time, thereupon automatically cutting the power to the fixing heater and
ultimately limiting the total consumption of power.
The printer is also able to print in toner save mode, in which it prints using less toner (lighter
output) to save on toner.
5. Auto interface switching mechanism
In addition to the parallel interface (Centronics compatible) and USB (V1.0 slave only) that come
as standard, the printer allows the connection of a build-in print server (option; 10Base-T/100Base-
TX). Depending on which interface board to use, the Printer will automatically switch among
parallel, USB, and Ethernet (option) interfaces.
6. Auto emulation switching
This printer supports the Hewlett-Packard’fs PCL5e and PCL-XL printer language. Also, Adobe
PostScript 3 can be provided by installing the optional Canon Adobe PostScript 3 Module A-65.
This enables auto emulation switching for PCL and PostScript based on the received data.

CHAPTER 1
III. SAFETY
A. Safety of the Laser Unit
Although invisible, laser light is used inside the laser/scanner unit. Do not disassemble the laser/
scanner unit, as exposure to laser light can damage your eyes.
The Printer’s laser/scanner unit is not designed for adjustment in the filed. The following shows
the label attached to the cover of the laser/scanner unit.
Figure 1-3-1
B. Safety of Toner
Toner is a non-toxic material composed of plastic and small amounts of colorings. If your skin or
clothes came into contact with toner, remove as much of it as possible using dry tissues; then,
rinse with cold water. (Do not use warm water. The toner will turn into jelly, and will not come off.)
Do not bring toner into contact with vinyl material. They tend to react with each other.
C. Safety of Ozone
The Printer’s charging roller generates a minute amount of ozone gas (O3) because of corona
discharge (only when the Printer is in operation).
The Underwriters’ Laboratory (UL) provides standards for amounts of ozone discharge, and the
Printer is verified to satisfy the requirements at time of shipment from the factory.

CHAPTER 1
V. INSTALLATION
A. Points to Note About Installation
The Printer is thoroughly adjusted and inspected at the factory before it is packed and shipped.
Installation work is important in that the Printer must perform in the field as it did when it passed
the factory inspection.
The service engineer must have a full understanding of the machine, and install it in an appro-
priate site using specific steps, following up the work with a thorough inspection.
B. Selecting the Site
The site of installation must meet the following requirements; if possible, visit the site of installa-
tion before the Printer is delivered.
1. Power supply
The power supply must satisfy the following:
• AC: ±10% of ratings
• Frequency: 50/60 ±2 Hz
2. Operating environment
The site must satisfy the following:
• Its floor must be level.
• Its temperature and humidity are as follows:
Ambient temperature: 7.5ºC to 32.5ºC (45.5 to 90.5ºF)
Ambient humidity: 5% to 90% RH (There must not be condensation.)
• It must be well ventilated, without accumulation of heat.
Avoid the following areas:
• subject to direct rays of the sun; as necessary, provide thick curtains to block out the sun.
• subject to magnetism (magnet, magnetic filed).
• subject to vibration.
• subject to dust.
• near a source of fire or water.

CHAPTER 1

CHAPTER 1
C. Unpacking and Installing
When a piece of metal is brought in from a cold to warm place, droplets of water can develop on its
surface. This phenomenon is known as condensation, and the use of an LBP suffering from con-
densation can cause various printing faults.
If the Printer has been brought in from a cold place, leave it alone for at least one hour before
unpacking it.
1. Unpacking the printer
1) Unpack the Printer.
2) Check to make sure that none of the following is missing:
1. power cord
2. toner cartridge
3. dust cover
4. CD-ROM
5. documentation
3) Remove the plastic bag used to cover the Printer, and check to make sure that the covers and
the like are free of image and deformation from transportation.
4) Slide out the cassette, and move the Printer to the site of installation.
5) Place the Printer at the site of installation. (Take care.)
• If the Printer is to be laid on a paper feeder, be sure that the position pins on the paper feeder
fit into the openings in the Printer’s bottom.
6) Remove the tape used to keep the parts in place.
7) Open the multifeeder tray, and pull the open/close lever to the front to slide out the front
cover.
8) Remove the protective tape used to keep the transfer charging roller in place.
9) Lock the open/close lever, and close the front cover and the multifeeder tray.
10) Slide in the cassette.
2. Unpacking and installing the cartridge
1) Open the bag used to pack the cartridge, and take out the cartridge.
2) Holding the cartridge as shown in Figure 1-5-13, shake it gently up and down about 5 to 6
times so that the toner inside it will be even.
3) Place the cartridge on a level surface. While holding the top of the cartridge with one hand, pull
the tab carefully with the other hand; then, pull straight out the sealing tape.
4) Open the multifeeder tray, and pull the open/close lever to the front to draw out the front
cover.
5) Holding the cartridge with both hands, fit it in the Printer. At this time, be sure to slide in the
cartridge carefully until it butts against the rear of the Printer.
