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 com­bined 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 stand­ard cassette and multifeeder, a maximum of about 1,100 sheets of paper (64 g/m
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/100Base­TX). 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.

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 (O
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.

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 installa­tion 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

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 con­densation 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.

CHAPTER 1

6 . Points to note when using the printer

1. When turning on the power switches, be sure to start with the external devices and then the
Printer. To turn off the power switches, be sure to start with the Printer and then the external
devices. If you turn on/off an external device while the printer is ON, noise can be introduced
to the Printer through the cable connecting the device and the Printer, causing an error in the
Printer.

2. Whenever connecting the Printer with an external device, be sure to turn off the power switches
of both and disconnect the power cords from the outlets. A fault can occur if the connector is
connected or disconnected while the power switch is ON.

3. Be sure to turn off the power switch of the Printer before installing or removing the following:
flash memory (option), Adobe PostScript Level 3 Module (option), expansion RAM DIMM (op­tion), hard disk (option), built-in print server (option).

4. Be sure to use a shielded cable when connecting the Printer’s parallel interface connector and
an external device. Moreover, make sure that the parallel interface cable is no longer than 3 m.

5. Be sure to use a twisted-pair LAN cable of Category 3 or higher when connecting the Printer’s
10Base-T/100Base-TX port and an external device to a 10Base-T network environment.

6. Be sure to use a twisted-pair LAN cable of Category 5 when connecting the Printer’s 10Base-T/
100Base-TX port and an external device to a 100Base-TX network environment.

7. Be sure not to touch the metal area of the connector before connecting or disconnecting the
USB cable while the power switch is ON.

8. Be sure to use SHUT DOWN MENU to shut down the printer if the optional Hard Disk HD-65
has been installed.

D. When Storing or Handling the EP-65 Cartridge

The cartridge is subject to the effects of the environment it is in whether it remains packaged or
installed in the Printer, and it takes on changes over time regardless of how many pages it has
printed. The rate of change depends on the site of installation or storage, requiring full care when
handling and storing it.

a. Before taking out of the package (removing the signal)

When storing the cartridge in a warehouse or a workshop, be sure that the environment meets the
requirements in Table 1-5-1; in addition,

1. Avoid direct rays of the sun.

2. Avoid a place subject to vibration.

3. Avoid shocks as by hitting or dropping it.

CHAPTER 1

b. After taking out of the package (removing the seal)

The photosensitive drum is made of photoconducting material (OPC), and tends to deteriorate
when exposed to strong light. The toner is also kept inside the cartridge, requiring care after the
cartridge has been taken out its the package. Advise the user to take full care when handling/
storing the cartridge.

1 . Storing the cartridge after taking out of the package (removing the seal)

1. Be sure to keep it in a protective bag.

2. Avoid areas exposed to direct rays of the sun or near windows. Do not leave it in side a car for
a long time, as the rise in temperature can be extreme.

3. Avoid areas subject to high/low temperature/humidity or areas subject to extreme changes in
temperature or humidity.

4. Avoid areas subject to corrosive gases (e.g., insecticide) or areas subject to briny air.

5. Make sure that the temperature is between 0ºC and 35ºC.

6. Avoid CRT displays, disk drives, or floppy disks.

7. Keep it out of reach of children.

2 . Effective period

The cartridge is verified to remain good for 2.5 years after the date of manufacture, indicated on its
body using an abbreviated notation. For the user, the period is indicated on the package and the
packing boxes (year, month; 2.5 years after the date of manufacture).

The use of a cartridge after the date indicated may not bring about expected print quality,

making it desirable to use it up before the date indicated.

c . Points to note when handling

1. When fitting a new cartridge, or if some areas of the output image show white spots because of
an uneven level of the toner inside the cartridge, hold the cartridge as shown, and shake it
carefully to the left and right [1] about 5 to 6 times then up and down [2] about 5 to 6 times to
even out the toner.

[1]

Figure 1-5-13

2. When transporting the Printer after taking out the cartridge from it, be sure to secure the
transfer charging roller in place for protection. Keep the cartridge in a protective bag to avoid
light. (See VI. ‘Relocating the Printer.’)

3. Do not place the cartridge near a CRT display, disk drive, or floppy disk. The magnetism from
the cartridge can damage the data.

4. The photosensitive drum is vulnerable to strong light. Avoid subjecting it to direct rays of the
sun or light 1500 lux or higher in strength. When exposed, it can produce images with white
spots or black bands. (If they occur, leave the machine alone for a while to correct the faults. If
the exposure is long, however, white spots or black bands may continue.)

1 - 19

CHAPTER 1

5. Do not attempt to touch the surface of the photosensitive drum of the cartridge. Further, do
not clean the photosensitive drum.

Drum

Figure 1-5-14

6. Do not place the cartridge upright or turn it over. Be sure it is laid with the label surface facing
upward.

7. Do not disassemble the cartridge.

Reference: If the photosensitive drum is exposed to light of 1500 lux (general lighting) for 5 min

and then left alone in the dark for 5 min, the faults can be corrected to a level satis­factory to practical uses. It is nevertheless important to avoid direct rays of the sun,
which is about 10000 to 30000 lux in intensity.

CHAPTER 1

VI. RELOCATING THE PRINTER

If the Printer must be relocated after installation by truck or other means of transportation, take
note of the following:

1 . Moving the printer with the cartridge removed

Once the cartridge is removed, the transfer charging roller can become displaced. Secure the
transfer charging roller in place using tape as follows before starting to move the Printer:

• If shipping tape is used, be sure to attach it so that the tape protection is over the gears and
the bushings, thus protecting the gears and the bushings of the transfer charging roller from
adhesive.

• If common tape is to be used, be sure to put a protective material (e.g., lint-free paper) between
the tape and the gears/bushings, thus protecting the gears and the bushings of the transfer
charging roller form adhesive.

Note: If the adhesive of the tape came into contact with a gear or a bushing, be sure to clean it

before using it.
