This is Canon’s first bubble-jet printer for use with a set top box (STB).
The design is a complete departure from conventional printers geared for personal
computers. The printer is designed to resemble an AV component to match the living
room interior.
It also has a MODE SELECTION switch, ink-low warning, and other functions which
are required as a non-PC printer. The large-capacity ink cartridges also make ink
cartridge replacements less frequent.
Part 1: Product Outline

1.2 Features
1) The printer is connected to the TV via the STB to enable images from the Internet to
be printed. It can also be used as a PC printer.

2) By using a paper cassette and the operation panel on the front of the printer, frontend operation is easy.
3) The printer uses three types of BJ cartridges: Black, color, and photo color.
The black and color cartridges use large-capacity ink cartridges to make ink cartridge
replacement less frequent.

2.2 Cautions for Disassembly and Reassembly
2.2.1 Cautions for ink stains (ink path/ink mist)
During servicing, be careful not to touch the ink path and get ink stains on the
printer, work table, and your hands and clothing.
The ink path includes the BJ cartridge’s ink cartridge supply inlet, the BJ cartridge’s
ink filter, the ink nozzles and maintenance jet receptacle, head cap, wiper, and waste
ink absorber.

Maintenance
Although the ink does not contain anything harmful to humans, it does
contain organic solvents.
Black ink:
Glycerin 56-81-5, ethylene glycol 107-21-1, isopropyl alcohol
107-21-1
Color ink:
Isopropyl alcohol 67-63-0
Photo ink: Glycerin 56-81-5, ethylene glycol 107-21-1, isopropyl alcohol
67-63-0
Be careful not to get the ink in your mouth or eyes.
If ink gets into your eyes, wash with lots of water and see a doctor. If you
consume a large amount of ink orally, see a doctor promptly.
Since the ink contains dyes, it will permanently stain clothing and other
materials.
Part 2: Maintenance
LR1
The BJ cartridge ejects ink onto the paper to print. After a long period of time or
heavy-duty use, ink mist created by loose ink droplets and ink bouncing off by the
paper will soil the platen, inside the cartridge cover, and around the purge section.
These soiled parts can soil the paper and your hands and clothing. To prevent this,
use a soft, damp cloth to wipe these parts clean.
When cleaning the purge section, be careful not to touch the cap or wiper
section.

2.2.2 Damage by static electricity
Due to the rubbing of clothing, static electricity can build up within the human body.
Static electricity can damage electrical components or alter the electrical
characteristics of components.
Never touch the contacts on the carriage and the BJ cartridge.
Handle the control board, sensor board or operation panel board with care not to
break them by static electricity.
2-4
Part 2: Maintenance
LR1
2.2.3 Preparation for transportation
While moving or transporting the printer, either leave the BJ cartridge in the printer
or keep it in the storage box. This is to prevent the ink from leaking and the BJ
cartridge’s ink nozzles from drying up.
(1) Carrying the printer
Before carrying the printer while the BJ cartridge is still installed, follow the
procedure below.
1) Turn off the printer by pressing the POWER button.
3) Disconnect the interface cable.
4) Disconnect the AC adapter’s DC plug from the printer.
Disconnect the AC adapter’s AC plug from the power outlet.
If you turn off the power by disconnecting the AC adapter or if you carry or
transport the BJ cartridge without putting it in the storage box, ink may
leak and the nozzles may dry up.
(2) Transporting the printer
Before transporting the printer, follow the procedure below.
1) Follow the procedure above for “(1) Carrying the printer” to turn off the printer and
disconnect the interface cable and AC adapter.
2) Pack the printer and AC adapter in their original packaging.
If you do not have the original packaging, use enough shock-absorbing material to
pack the printer.
2-5
Maintenance
2) Check that the BJ cartridge is at the capping position (right end of printer). If it is
not at the capping position, turn the printer on and off by the POWER button so that
the carriage is moved to the capping position.
Part 2: Maintenance
LR1
2.3 Disassembly and Reassembly
Cautions for disassembling and reassembling the printer are stated below.
As for the disassembly procedure, refer to the Parts Catalog. The illustrations in the
Parts Catalog are numbered according to the order of disassembly.
2.3.1 Removing plastic parts
The printer has many plastic parts. When disassembling the printer, be careful not to
break or bend the plastic hooks. For details on disassembly and reassembly, refer to
the Parts Catalog.
Some plastic parts contain glass fiber to improve the rigidity for better
precision. Since these parts are less flexible, their plastic hooks are
especially easy to break. During disassembly, do not exert excessive force
on plastic parts with a screwdriver or other instrument.
2.3.2 Removing and installing tap screws
The printer uses tap screws to fasten the upper and bottom cases, the control board
and bottom case, the pick-up unit and bottom case unit, and the chassis platen unit
and bottom case. The removed tap screws will have residue from the mold in which
the internal thread was made. Since the residue may crush the screw threads, clean
off the residue from the tap screws before re-installing or use new tap screws.
2.3.3 Cable positions
Lay the cables connecting the motors, sensors, and control board according to the
stipulated position.
For positioning the cables, refer to the Parts Catalog.
2.3.4 Deformation of spur tips
Be careful not to deform the spur tips.
The spur contacts the paper after the printing.
If the spur’s tips are deformed, the contact area with the paper will become larger,
increasing the amount of ink on the paper transferring onto the spur tips which will
soil paper with dotted lines.

2.3.5 Feed gear cautions
When disassembling or reassembling the printer, do not touch the gears of the at
paper feeding section. Note that even a slight scratch on the gears will cause irregular
paper feeding during high-quality printing.

2.6. Spur Cleaner
If the tips of spurs become dirty with ink, spur marks can be left on the print images.
In such case, clean the spurs by using the spur cleaner (QY9-0055-000). The spur
cleaner can be used until it loses its intended effect.
2.6.1 Usage
1) Moisten the fabric part of the spur cleaner with approx. 5 cc of water.
Moisten the fabric with water, as shown below, so that the fabric absorbs enough
water from end to end, especially the areas that will contact the spurs.
Be careful not to moisten the fabric with too much water. In case too much water
is used, there is a possibility that water will be squeezed from the spur cleaner
when passing through the paper feed roller, spread inside the printer, and cause
failure.
Be careful that the water
is absorbed by the fabric
from end to end.

If possible, print out the nozzle check pattern with paper fed from the cassette.
If you must feed the paper manually to print out the nozzle check pattern, follow the
procedure below:
1) Without setting any paper in the manual-feed slot, and the paper cassette try to
print out the nozzle check pattern. A paper-feed error will occur.
2) Insert one sheet of paper into the manual-feed slot, then press the RESUME button.
The paper-feed error will be canceled and the nozzle check pattern will be printed.
1.3.3 Resetting the dot counter
After replacing the ink cartridge or BJ cartridge with a new cartridge, follow the
procedure below to reset the dot counter.
1) Open the cartridge cover. The cartridge will move to the center.
2) Check that the ink cartridge whose dot counter is to be reset is installed. (The dot
counter reset will be enabled only for the cartridge installed.)
3) When resetting the dot counter for the black ink cartridge, press the “BLACK”
COUNTER RESET button. To reset the dot counter for a color ink cartridge, hold
down the “COLOR” button and release when the beeper sounds.
After replacing the ink cartridge or BJ cartridge to a new one, be sure to
reset the dot counter. If the dot counter is reset without the ink cartridge
being replaced or if the dot counter is not reset after the cartridge is
replaced, the remaining ink amount detected will not be correct.

1.3.4 Cleaning the pick-up roller
When dust and paper bits adhere to the pick-up roller, the paper feeding becomes less
efficient. In such a case, use a cleaning sheet to clean the pick-up roller as described
below.
Use the exclusive cleaning sheet included in the pack of high-resolution paper.
1) Put the cleaning sheet in the paper cassette.
Peel off the cleaning sheet’s backing. Lay the sheet with the sticky side facing up.
Set the sticky side toward the claw.
2) Open the rear cover.
3) Hold down the RESUME button and release it when the beeper sounds once.
The cleaning sheet will be fed into the printer and discharged out the back of the
printer. The error indicator will light.
4) Take out the cleaning sheet and close the rear cover. Press the RESUME button.
You can also clean the pick-up roller with the printer driver if the printer
is connected to a personal computer. See 1.2.1 Function settings with the
printer driver on page 3-6.
The printer has an auto power on/off feature.
Upon factory shipment, the printer is set as follows:
Auto power on: Enabled
Auto power off: Enabled, 30 min.
To disable the auto power on/off, hold down the POWER button and release after the
beeper sounds the stipulated number of times.

2.2 Printing the EEPROM Data
The EEPROM records various data such as the settings, total page count of each BJ
cartridge, total waste ink absorption amount, and the dot counter for each ink
cartridge. The data in EEPROM serves as a general guide to how much the printer has
been used.

2.3 Setting the Waste Ink Amount
The printer detects “waste ink full” based on the total waste ink absorption amount
recorded in the EEPROM. Thus, after you replace the waste ink absorber, you must
also reset the total waste ink absorption amount.
Also, after replacing the control board, you must reset the new control board’s
EEPROM and set the waste ink absorption amount for the waste ink absorber installed
in the printer base unit.
1) After replacing the control board
Before replacing the control board, visually check the waste ink absorption amount in
the waste ink absorber in the printer base unit.
After replacing the control board, set the waste ink absorption amount you found out
visually to the EEPROM.

2) After replacing the printer base unit (waste ink absorber)
After replacing the printer base unit, set 0% as the waste ink absorption amount to
the EEPROM (EEPROM reset).
The EEPROM contains various data such as the settings, total page count for each BJ
cartridge, total waste ink absorption amount, and the dot counter for each ink
cartridge. When the EEPROM is reset, all those data will be reset as well.

1. TECHNICAL REFERENCE
1.1 Description of Paper-feed Section
1.1.1 Construction of paper-feed section
The printer’s paper-feed section consist of the pick-up section, transport section, and
paper delivery section. The function and construction of these components are
described below.

• Positioned to pick up the paper from the casette.
Figure 5-2 Pick-up Section
5-1
Appendix
The pick-up roller picks up the paper from the cassette and the ASF rollers deliver it
to the transport section.
(During manual feed, the pick-up section is not used since the paper is inserted
directly to the transport section through the manual-feed slot.)
The pick-up unit has a pick-up roller, driven by the pick-up motor, and ASF rollers.
When the printer receives a printing command or pick-up command, the pick-up
roller rotates once to deliver the paper to the ASF rollers and paper guide rollers.
When the ASF rollers grab the paper, the pick-up roller rotates to its initial position so
it does not obstruct the paper transported by the ASF rollers. (Fig. 5-2a)
The ASF rollers transport the paper up to the transport section’s paper feed roller.
When the paper feed rollers grabs the paper edge, the ASF rollers move to its standby
position. The paper is thereby freed from the ASF rollers, and the transport section
does not obstruct the paper transport. (Fig. 5-2b)
Part 5: Appendix
LR1
1.1.3 Transport section
The transport section consists of the paper feed roller driven by the paper-feed motor
and the pinch roller. After these two rollers take the paper through the printing
position, they deliver the paper to the paper delivery section.
(1) Cassette feeding
When the paper delivered from the pick-up section turns on the paper-end sensor,
the paper-feed motor starts up and drives the paper feed roller.
After the paper feed roller first rotates in reverse to fix the skewed sheet (see “1.1.7
The form alignment function”), it rotates forward until the paper reaches the printing
start position.
If the paper-end sensor does not turn on even though the pick-up section executed
the pick-up operation, a paper-feed error will result.
(2) Manual feeding
When the paper inserted in the manual-feed slot turns on the paper-end sensor, the
paper-feed roller rotates to feed the paper. When the front edge of the paper is
detected by the paper delivery sensor, the paper-feed roller rotates in the reverse
direction and sends the paper back to the starting position for printing. The
operation then stops.
When the paper does not turns the paper delivery sensor on under the rotating the
paper-feed roller, the paper feed motor rotates to send the paper to the manual-feed
tray for discharge. Then, the failed manual feed warning is indicated.
Paper-feed roller
Paper-end sensor
Paper
Paper delivery sensor
Figure 5-3 Paper Path for Manual Feeding
1.1.4 Paper delivery section
The paper delivery section discharges the paper with the eject roller (driven by the
paper feed roller’s rotation) and spur.
To avoid soiling the printed side of the paper, the spur presses the paper against the
eject roller while the paper is discharged.
If the paper delivery sensor detects that the paper was not discharged after printing, a
paper jam error is indicated.
5-2
Part 5: Appendix
LR1
1.1.5 Remaining paper indication function
The printer can indicate the amount of paper remaining in the cassette. When the
paper-loaded cassette is installed in the printer, the stack of paper pushes up a lever
which indicates the remaining amount of paper.
The drum has white and black sections. The amount in the white section can be
checked through the window at the front of the printer.

1.1.6 Pick-up retry function
The pick-up retry operation is executed if the paper-end sensor cannot detect the
paper after the pick-up operation. The pick-up is tried again. If the pick-up retry is
executed once and the paper pick-up still does not work properly, a paper-feed error
occurs.
1.1.7 The form alignment function
Even if the paper is skew when it is picked up, the paper is aligned by the transport
section. The paper feed roller rotates in reverse and the paper is set against the
pressure roller so that the paper edge becomes parallel to the paper feed roller.

1.2 Purge Section
To maintain printing quality, the purge section maintains the BJ cartridge’s nozzles.
1.2.1 Cleaning function
Cleaning is performed to prevent defective printing caused by improper ejection of ink
by the BJ cartridge head. The cleaning operation combines purging, wiping, and
maintenance jet. It executes the following operations:
• Suction:
The ink is sucked out of the head to refresh the ink in the head
with new ink.
• Maintenance jet: To eliminate any air bubbles in the head’s nozzles and to remove
waste particles near the nozzle openings, ink is ejected from the
nozzles onto the cap and maintenance jet receptacle.
• Wiping:
Wipe off paper bits and dried ink on the head’s face plate.
Depending on the BJ cartridge type and the printer’s condition, the cleaning time and
combination of cleaning operations will differ.
Cleaning is performed at the times below to ensure that the head produces highquality printing.

1.2.2 Description of Purge Section
Cleaning is done by the printer’s purge section. When the carriage moves to the right
from the home position, the trigger gear attached to the paper-feed gear will start
turning. The paper-feed motor’s driving force is thereby conveyed to the purge
section’s gear and cam to drive the cap, wiper, cylinder, and pump.

b) Suction
The purge section’s cap is connected to the pump. The piston in the pump is
coupled to the cylinder gear which is driven by the pump gear. Ink is drawn from
the head to fill the cap when the piston moves to the right to seal the pump. Then
the piston is moved to the left to open the pump. The ink in the cap is then drawn
into the pump and absorbed by the waste ink absorber via the ink absorber.
c) Wiping
The wiper is set or released by the carriage’s wiping hook. When the carriage moves
to the right from the home position, the wiper touches the head’s aluminum plate
and any dirt on the wiper is removed before the wiper proceeds to wipe off ink on the
face plate. Also, when the wiper goes down, ink falls off toward the gear. (Wiping)
After the wiping operation, when the carriage moves further to the right, the
carriage’s hook lever pushes down the latch lever so that the wiper goes down.
(Wiper released)
5-5
Appendix
a) Capping
Capping resolves or prevents improper ink ejection due to a dried-out face plate on
the head. Since the pump arm moves via the pump gear’s cam, the cap moves up
and down for capping.
When the carriage goes to the home position, the cap is pushed onto the head’s face
plate to cap it.
Capping is done at the following times:
1. When the power is turned off with the POWER button.
2. When the data is not received within the stipulated time during printing.
Part 5: Appendix
LR1
Next, when the carriage moves to the left, the carriage’s hook lever pushes down the
wiper lever so that the wiper goes to the wiping position again. (Wiper ready
position)
Wiping is executed at the following times:
1. During printing, when the printing dot count or printing time exceeds the
stipulated value.
2. After purging.
3. Before capping.

1.3 Description of Carriage Section
1.3.1 BJ cartridge mounting function
The carriage holds the BJ cartridge and locks it in place mechanically. When a BJ
cartridge is installed on the carriage, the carriage ribbon cable’s contact is pressed
against the BJ cartridge’s signal connector to enable printing signals to be
transmitted from the control board.
While the printer is turned off, the carriage is locked at the capping position. On the
back of the carriage are wiping hooks which release the wiper or sets it to the ready
position. It also has a home position edge which blocks the home position sensor on
the chassis.

Figure 5-8 Carriage Section Structure
1.3.2 Carriage drive control

Appendix
The carriage is driven by the carriage motor via the carriage belt. The carriage
position is controlled by the MPU sending a stepping pulse to the carriage motor.
The carriage position is detected by the home position sensor (on the chassis)
detecting the carriage’s home position edge.
The mechanical shifting that occurs during bi-directional printing is corrected
automatically by detecting the carriage’s home position in both directions and shifting
the printing starting position with software. A shift correction is made for the
initialization after the power is turned on or when the printing starts after the printing
mode has been changed.

1.4.3 USB interface
With USB, up to 127 peripheral devices can be connected to the computer. It is a
serial interface with a high-speed transmission rate of 12 Mbps. It also enables
devices to be hot-swappable which means they can be connected or disconnected even
while the computer and printer are on. Each device is connected via a port on a hub.
The hub tells the computer which ports are connected or unconnected.
Data transmission
With USB, data is transmitted in transfer units called frames which are divided into 1
ms. A series of frames constitute the transmission.
To synchronize with the local clock, all packets start with the SYNC field and end with
the EOP (end of packet) field.
The frame string starts with the SOF (start of frame) packet. The SOF consists of the
PID (packet identification field) which indicates the packet’s type and direction, the
frame No., and CRC (cyclic redundancy check) for error checking.
After SOF, the frame contains a token packet and a handshake packet that indicates
the status of the data and flow control.
The token packet consists of an address field that can specify PID and 128 addresses,
an ENDP (end point) field, and CRC.
The data packet contains PID, data field, CRC, and EOP.
The handshake packet contains only PID.

Figure 5-11 USB Data Transfer
Data encoding and decoding
The USB data transfer string is ultimately codified in the NRZI (Non Return to Zero
Invert) format. When the original data bit is 0, the transmission data bit is inverted.
When the original data bit is 1, the transmission data bit is maintained as is.
If the transfer data’s level does not change for a long time, the data’s receiving end will
be unable to acquire the data’s sample position synchronization. This may cause the
bit to shift. This is prevented by a method called bit stuffing. The original data before
NRZI codification has bit 0 added one time after six consecutive bit 1’s.

1.4.4 Automatic interface switching
The printer has an automatic interface switching feature.
When there is no printing from either the USB or parallel interface, printing can be
started from either interface.
After printing starts and ends with one interface, the interface cannot be switched
until the receiving buffer becomes empty.

1.5.3 BJ cartridge printing drive control
The black BJ cartridge executes the same printing drive control as the BJC-85.
1.5.4 BJ cartridge identification
The printer detects the bubble jet head’s board signal via the cartridge signal contact.
It thereby detects the type of BJ cartridge installed and the head rank.
For details on the signal contact, see page 5-17 (Table 5-4 HEAD INSTALLATION STATUS
AND SIGNAL DETECTION).
All BJ cartridges are divided into one of thirteen types in accordance with the
production irregularities of the bubble jet head’s heater characteristics. While
compensating for these irregularities, the printer executes optimum ink ejection
control.
