Chapter 1: General Description
• Load the paper with the side that does not have green lines facing up.
• Use mirror printing to print or copy the image onto the T-shirt transfer.
• If the T-shirt transfer is curled, flatten it by curling it in the opposite direction.
General print media guidelines
• Paper types you cannot use
Do not use the following:
–Creased print media
–Curled print media
–Wrinkled print media
–Moist print media
–Print media that is too thin (It should be at least 64 g/m2 or 17 lb.)
–Print mediathat istoo thick(Itshouldnot bemorethan105g/m2 or 28lb.,exceptfor Canon
print media.)
–Print media with holes (e.g. punched holes)
–Postcards with photographs or stickers adhered to them
• Hold the print media as closely as possible to its edges and try not to touch the printing
surface. Printing quality will deteriorate if the printing surface is damaged or becomes.dirty
• Do not touch the printing surface until the ink has dried.
• Some print media may curl and the printing surface may smudge if you have used a large
amountof inkfor printing. If this occurs,move thepaper thickness lever to theright.
Paper that tends to curl is not recommended for printing photographs or graphics. Use for
printing mainly text.
• Do not use print media that is in bad condition. If the print media is curled, uncurl
it before printing.
• Place the print media you have not used back into its packet and store out of direct sunlight
in a place where temperature and humidity is low.
• Photo Paper Pro guidelines
–Do not touch the printed surface until the ink is fixed (approx. 30 minutes). Colours in dark
images may appear indistinct at first, but will become clearer after about 30 min.utes
–Images may smudge if you place them in an album before the ink is completely dry. It is
recommended that you allow the ink to dry for 24 hours.
–Do not attempt to dry the ink with a hairdryer or by exposing printed sheets to direct
sunlight.
–Do not store or display printouts in hot, damp, or humid conditions. Never expose them to
heat or direct sunlight.
–Storeprintoutsin photo albums,photo frames,orpresentation binders to protect them from
direct exposure to air or sunlight.
–Donot mount printouts in anadhesive-type albumasyoumaynot beableto remove them.
–Be aware that some types of clear plastic folders and albums may cause the edges of the
paper to turn yellow.

Chapter 2:Technical Reference
3.1.1 Carriage
The carriage holds one BJ cartridge in place. The carriage belt driven by the carriage motor (DC motor)
moves the carriage horizontally back and forth across the paper.
Regarding the carriage's position control, the initial position is detected when the carriage goes against
the right wall which is the home position.
After that, the carriage position is detected by reading the pulse from the encoder film.
The paper spacing position is read from the carriage position when the carriage goes against the left wall.
3.1.2 Purge section
The purge section, driven by a dedicated purge motor, consists of the wiper, pump, cap, and carriage
lock.
The wiper maintains the head face surface to ensure high-quality printing. The ink suction feature
enables the ink to be readily ejected from the nozzles.
When the BJ cartridge is not in use, the nozzles are protected by a cap, and the carriage is locked in
place.
The motor's running direction controls the ink suction operation or capping/wiping/valve open/closing
operation.
3.1.3 Paper feed section
The paper feed section consists of the paper feed components, paper transport section, and paper
discharge section.
Paper feed
Paper is picked up automatically from the auto sheet feeder.
The feeder is designed to accommodate various sizes of paper (as large as LGL), picking up individual
sheets and forwarding them to the feeding block.
Paper transport section
The paper feed section, driven by the paper feed motor, keeps the sheet of paper flat and horizontal on
the platen and rotates the feed roller to move the paper horizontally to and beneath the print head.
Paper eject section
After printing, paper is ejected onto the discharge tray by the eject rollers.
After the sheet of paper leaves the paper feed rollers, the eject rollers take over to eject the paper.

3.2 Paper Feed Section
3.2.1 Paper feed components
The auto sheet feeder separates recording paper by rotating the separation roller in the opposite
direction of pickup. Compared with other auto sheet feeders, it shows better separation performance.
Pick up roller
[One sheed sending]
[Sparation]
Separation roller
Figure 2-6 Paper Feeding
The pickup roller receives a rotating force in pickup direction, whereas the separation roller receives it
in the opposite direction of pickup through a torque limiter. The rotating force acting on the separation
roller is weaker than that acting on the pickup roller, causing it to rotate in pickup direction.
As long as pickup is normal, the rotating force acting on the separation roller is weaker than the friction
between the recording paper and the separation roller, thereby permitting the separation roller to
forward the paper to the feeding block.
If double-feeding occurs, however, the force acing on the separation roller will be stronger than the
friction between the paper and the separation roller, thus rotating the separation roller in the opposite
direction of pickup and, consequently, forcing the second sheet back to the recording paper tray and
forwarding the 1st sheet to the feeding block.

3.2.2 Paper transport section
In the printing block, the gap between print paper and the print head is kept at a specific distance by
forcing the paper against the platen between the pressure roller and the paper feed roller and also
between the spurs and the eject roller.
When the paper has been moved as far as the print start position, printing starts on the platen.
3.2.3 Paper discharge section
After printing has taken place, the paper is discharged by the drive of the eject roller with the sharp-
edged spurs forcing themselves on the printed side against the platen, while making sure that the
printed face will not be soiled.
The delivery block consists of an eject roller and spurs. As soon as printing ends, the paper moved by
the work of the paper feed roller and the pinch roller is discharged using the rotation of the eject roller
and the spurs.

3.3 Ink residual quantity detection
The machine is not equipped with a sensor used to detect the level of ink remaining in its tank.
The absence of such a sensor is made up for by counting the dots in a deposit. When these dots reach a
specific number, the LCD will indicate a message alerting the user that the ink is running out and
prompting replacement of the tank, which must be replaced when the output starts to show fuzzy images or
becomes blank.
When the ink tank has been replaced, the LCD indicates a message, asking if the ink tank has been
replaced. Select 'Yes' in response. (Selecting 'No' will do away with resetting the ink counter, which
prevents correct detection of the level of remaining ink.)
The level of remaining ink may be checked by selecting 'INK VOLUME' from a menu.

3.4 Purge Section
3.4.1 Purge section functions
In order to maintain good printing quality, the purge section maintains the BJ cartridge's nozzles. The
purge section's functions consist of capping and cleaning.
a) Capping
The purge unit's cap is pressed against the print head's face to protect the nozzles from dust, etc., and to
prevent the nozzles from drying out. To prevent the capping position from shifting, the carriage is
locked in place at the same time.
When the cap is open while the printer is on standby for printing and a certain period of time elapses ,
the print head will be capped automatically. You can also cap the print head by pressing the ON/OFF
button to turn off the printer.
b) Cleaning
Cleaning executes the following operations:
Wiping: Paper residue and dried ink on the print head's face plate are wiped off.
Suction: The ink is sucked out of the print head to refresh the nozzles 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.
Cleaning is performed at the times below to ensure that the head produces high-quality printing.

Chapter 3: Assembly and Disassembly
1. ATTENTIONTO BE PAID DURING ASSEMBLY/ DISASSEMBLY
1.1 Safety Cautions
Electrical shock
In order to prevent any risk of electrical shock, always be sure to check that the power cord and modular
jack have been removed. Also, remove all cables connecting to the computer. When conducting service
that requires the main unit to be powered on, be sure to wear some kind of earthing, such as a wrist strap,
etc. Otherwise, there is a danger of conduction and electrical shock.
Parts which are generally likely to cause electrical shock are as follows.
• Power supply unit primary (supplied with AC voltage)
• Telephone line primary
• LBP engine high voltage contacts (for high voltage during developing and transfer)
Hightemperature
In order to prevent burns during disassembly, allow at least ten minutes, after the power has been switched
off, for the high temperature components to cool down.
General high temperature components are as follows.
• Motors
• Power supply unit
• Elements on driver ICs, etc., on PCBs (in particular, ICs with heatsinks)
• BJ cartridge aluminium plate (for BJ cartridge engine models)
• Fixing unit and peripheral covers (for LBP engines)
BatteryReplacement
The batteries must be replaced correctly to avoid explosion. Do not replace any battery with one not
indicated for the machine, ie., use one of the same type or equivalent. Be sure to dispose of used batteries
according to local laws and regulations.
Fire
It is dangerous to throw lithium batteries and parts and components containing flammable substances,
such as cartridges, etc., into fire. Such parts and components must be disposed of in accordance with local
laws and regulations.
Ignition
When using solvents such as alcohol, etc., while conducting service, there is a danger of fire igniting from
heat from internal circuitry and from sparks. Before using any such solvents, be sure to switch off the
power and allow time for high temperature parts to cool down. Make sure that there is sufficient
ventilation when working with solvents.
Movable parts
In order to prevent accidents with movable parts, be sure to remove the power cable when conducting
service that requires disassembly. Also, take care that personal accessories and hair, etc., are not caught in
any moving parts.

Chapter 3: Assembly and Disassembly
1.2 General Cautions
Damage due to electrostatic discharge
This machine contains contact sensors and printed circuit boards that use ROMs, RAMs, custom chips and
other electronic components that are vulnerable to damage by electrostatic discharge.
Be careful to avoid any damage from electrostatic discharge when conducting service that requires
disassembly.
Static electricity warning
Electrostatic discharge can destroy electronic components and alter electrical
characteristics. Plastic tools and even your hands, if they are not earthed, contain
sufficient static electricity to damage electronic components.
The following materials may be used as countermeasures against electrostatic discharge:
• an earthed, conductive mat,
• an earthed wrist-strap,
• crocodile clips for the purpose of grounding metallic parts of the main unit.
For service conducted on the user’s premises, etc., where such countermeasure materials are not available,
the following countermeasures may be employed.
• Use anti-static bags for the storage and carrying of PCBs and electrical elements.
• Avoid silk and polyester clothing and leather soled shoes, favouring instead cotton clothes and rubber
soled shoes.
• Avoid working in a carpeted area.
• Before beginning the work, touch the grounded earth terminals of the main unit in order to discharge any
static electricity.
• Use a wrist-strap and earth the metal parts of the main unit.
• PCBs and electrical elements must lifted around the edges and their terminals must not be touched.
Caution against electrical shock while working with power on
In cases where service must be carried out with power on, via a connected power cable,
be sure to wear an anti-static wrist-strap or other earth, in order to prevent an electrical
path being created through your body.
Application of grease
Grease must not be applied to any parts that are not so designated. If grease comes into contact with the
rubber cap of the purge unit or wire, the BJ cartridge nozzle may become blocked and the cartridge
rendered unusable. Also, never use any other than the specified type of grease. Otherwise, plastic parts
and rubber parts may melt or be otherwise deformed.
Attaching and removing cables
Attaching and removing cables with the power still on may cause breakdowns and should be avoided. In
particular, flat cables are likely to cause short circuits. When attaching or removing cables, always be sure
to turn the power off.

Chapter 3: Assembly and Disassembly
1.3 Product-Inherent Cautions
Prevention of ink-soiling
Be careful when handling the BJ ink cartridge nozzle, the ink pad, head cap, head wiper and waste ink pad.
Residual ink may soil the main unit, working surfaces, your hands and clothes, etc. The ink is water-
soluble, but because it contains pigments, it will not wash out of clothes.
The ink does not contain any substances that are harmful to humans, but does contain organic solvents
(isopropyl alcohol 67-63-0, diethylene glycol 111-46-6, glycerin 56-81-5 and ethylene glycol 107-21-1).
If the ink should accidentally get into someone’s eyes, rinse the affected eye with plenty of clean water
and seek medical attention. If a large quantity of ink is accidentally swallowed, seek medical advice
immediately. In such a case, let the doctor know exactly what is written on the BJ cartridge label.
Conductivity of the ink
The ink used in the BJ cartridge is conductive. This means that, if the ink leaks, mechanical parts should
be wiped with a dampened paper towel or similar and electrical circuits wiped with tissue paper so that all
ink is removed from below the IC chips.
If power is switched on while ink is leaking on the electrical circuits, the circuitry may short out and be
damaged. If ink is leaking, the power must be switched off.
1.4 Action in the Event of Abnormality (All Clear)
In the event of extreme noise or shock, etc., in very rare cases, the display may go out, and all the keys
become inoperable. In that case, perform an All Clear. This operation returns all values and settings to
their default settings. However, as all settings, such as received images and user data, service data, etc.,
will be re-initialised, be sure to note down any settings that you will need to re-enter later.

1.5 Transporting the machine
If you must transport the machine as when returning it after repair work, be sure to perform the following
work:
(a) Mount the BJ cartridge (printer head) to the carriage.
(b) Turn off the printer so that the carriage locks at the home position.
If the BJ cartridge (print head) is not on the carriage, the ink may dry and harden. So even
while transporting the printer, leave the BJ cartridge mounted on the carriage. Also, if the
carriage is not locked at the home position, it will move while the printer is being
transported. This may strain the paper feed encoder film.

Caution When Replacing SPCNT Board
To replace the SPCNT board, perform the following:
a) Caution before replacing
NOTE
You will need to execute 'all clear' at the end of replacement. As necessary, print out the
following data:
a-1) Image Data in Image Memory
The image data stored in image memory will be lost when the power is turned off.
Before turning off the power, check to make sure that all images have been printed
out.
a-2) Data on the Amount of Waste Ink in the Absorbent and the Print Position
AdjustmentData
The EEPROM on the SPCNT board is used to remember the amount of waste ink
collected by the absorbent and print position adjustment data. Be sure to replace the
waste ink absorbent at the same time whenever you are replacing the SPCNT board.
After replacement of the board, be sure also to enter '0' as the amount of waste water in
the new waste ink absorbent and adjust the print position.
a-3) Service reports
Select service mode, and select 'SERVICE REPORTS' using the </> button. Press the
OK button; then, select the type of list to generate using the </> button.
b) Replacing the SPCNT Board
(1) Remove the existing board.
(2) To prevent exhaustion of the battery otherwise occurring in storage, the jumper
plug (JP3) of the service SPCNT board (if new) is not shorted. Be sure to short the
plug before use.
(3) Mount the new SPCNT board, and put back all parts you may have removed.
(4) Turn on the power, and execute 'all clear'. For details, see the instructions to follow
in response to an error (See this Chapter 1.4 Action in the Event of Abnormality (All
Clear)).
(5) After executing 'All Clear', enter the data you have previously printed out as
necessary (battery backup).

Replacement of waste ink absorbers
The waste ink absorbers are designed to sop up any excess ink ejected during the
cleaning operation or during ink squirting for maintenance, in order to maintain the
good printing quality of the BJ cartridge. The volume of ink absorbed is counted and
these data stored in the EEPROM on the SPCNT board. Once the volume is judged to
have reached 100%, the message "CHECK PRINTER" (error code ##343) will be
displayed, and printing will stop, in order to ensure that the volume of ink absorbed does
not exceed the allowed limit. To clear this error, you need to replace the waste ink
absorbers and reset the waste ink volume counter. Refer to Chapter 4, 4.2.2 error code,
Action for ##343, for details on how to reset the waste ink volume counter.

Installing and removing the carriage encoder film
The carriage encoder film is fixed in place and held taut by the torsion spring.
When you install or remove the carriage encoder film, you have to stretch the torsion
spring. Be careful not to pull the torsion spring too much in the direction of the arrow.
Otherwise, you will not be able to properly install the carriage encoder film the next
time.
Therefore, when installing or removing the carriage encoder film, be very careful not to
pull the torsion spring too much.
Figure 3-12 Encoder Film
Handling encoder film
(1) Be careful not to get any grease on the encoder film
If grease gets on the carriage encoder film, the film's slits will not be read correctly,
resulting in error. If grease gets on the film, use alcohol to wipe it off completely.
(2) Do not fold or scratch the encoder film.
If the film is folded and a white line is created or if a slit is scratched, replace the
encoder film.

Automatic adjustment of CS LED lights-on duration
The CS LED lights-on duration, which can be adjusted via button operation, is also
adjusted automatically in the following cases:
NOTE
• When power is turned ON then SRAM data is corrupted
When this product is shipped, after factory adjusment of the CS LED light-on
duration, the exposure control data is stored in SRAM. Because this data is preserved
by the Lithium battery even if the power supply is shut off, further adjustment is
unnecessary in almost all cases. When the machine’s power switch is turned on, the
data stored in SRAM is checked for correctness by Checksum, and if any data in
SRAM has been lost, adjustment of CS-LED lights-on duration is automatically
performed at that time. At first, a check is done for the presence/absence of a
document, and if there is no document, exposure control is performed automatically.
Exposure control data measured after this is stored in SRAM. When a document is
present, scanning is done in an error condition, an abnormal image is output, and the
contact sensor is aware that there is an abnormality.

3. ADJUSTMENT
3.1 CS LED Lights-on Duration Adjustment
a)Overview
This adjustment is used to eliminate uneven scanning which can result from variations in light intensity
between individual LED’s. Performing the adjustment will therefore have an effect on scanned and
copied images.
The adjustment value is registered in an SRAM IC which has lithium battery back-up and will not be lost
even if power is turned off. However, the SRAM data can become damaged, for example by battery
depletion. In this case, the machine checks the data’s validity the next time power is turned ON. If the
data is invalid, the adjustment is made automatically. Because the user is automatically prompted, it is
almost never necessary to perform this adjustment during normal use. However, if the SPCNT board,
Contact sensory ass’y, or lithium battery is replaced, be sure to perform this adjustment. Also, if the color
or brightness of scanned or copied images is faulty, performing this adjustment may correct the problem.
b) Procedure
(1) Check that the pressure plate is closed correctly, then perform the adjustment by following the steps
described below.
