INTRODUCTION
This Service Manual provides basic facts and figures needed to service the laser beam printer LBP2000 (hereafter, the Printer), performed to ensure initial product quality and performance.
The following options may be used in combination with the Printer:
•Universal Cassette UC-65
•Paper Feeder Unit PF-65
•Hard Disk HD-65
•Ether Board EB-65
This Service Manual also covers these options. For others, see their respective Service Manuals.
This Service Manual consists of the following chapters:
Chapter 1, ‘Product Outline,’ introduces features and specifications as well as how to install and
use the Printer.
Chapter 2, ‘Operation,’ explains the principles of operation used in the mechanical/electrical
systems of the Printer according to function as well as timing at which associated
mechanisms operate.
Chapter 3, ‘Mechanical System,’ shows the mechanical construction of the Printer and how to
disassemble/assemble and adjust its components.
Chapter 4, ‘Troubleshooting,’ indicates how to correct various faults and make checks/adjust-
ments, and provides standards to follow.
APPENDIX contains a general timing chart, general circuit diagrams, and list of signals.
Changes made to the descriptions because of product improvement or the like will be commu-
nicated in the form of Service Information bulletins as they occur.
All service persons are expected to go through this Service Manual and Service Information
bulletins for a full understanding of the Printer while equipping themselves with skills and knowledge used to identify and correct faults in the Printer.
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.

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.

CHAPTER 1
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]
[2]
[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.
