1. Precautions
1-1. General precautions
* Unplug the power cord from the AC outlet before performing maintenance.
* Be careful to avoid getting neckties, clothing, or long hair tangled in moving parts.
* If you must perform work while the machine power is on, exercise the utmost caution.
* Never perform maintenance while the machine is operating.
- Be caution about the automatic descent operation of the transfer unit.
- After predetermined time, the descent operation of the transfer unit to the standby position and
the sliding operation of the cleaning unit to ink heads position are automatically performed.
- Be caution not to turn ON the machine and be injured by pinching hands or arms when covers
are removed for maintenance work.
* Work carefully to avoid injuring yourself on the sharp edges of metal sheets or springs.
* When a wrist watch, a ring, etc. become the obstacle of work, work by removing it.
1-2.Special precautions for color inkjet printers
* Maintain the device to keep it free of dust (including paper dust).
- Dust and paper dust adhering to the nozzles of the print heads may result in a misre.
- Clean internal paper paths with a vacuum cleaner to remove dust (including paper dust) at
eriodic intervals - for example, when replacing waste ink tanks (periodic inspections). Clean more
or less frequently, depending on your specic operating conditions. The amount of paper dust
that accumulates in the machine will depend on the type of paper used.
- Never use an air duster, since doing so will raise paper dust and causes misres.
* Ink storage
- Store ink cartridges in the specied conditions. Follow the [rst in, rst out] principle when
removing ink cartridges from storage, and use ink promptly.
- Do not store ink cartridges in environments that may degrade the ink. Degraded ink is more likely
to cause nozzle misres and other problems.
* Precautions for use of inks
- Do not shake the ink cartridges before using.
Shaking the bottle will generate air bubbles into the ink solution, making nozzle misres more
likely.
- Do not rell with ink.
- Check ink left unused for extended periods after ink cartridges are opened to make sure it
remains usable.
Ink left in ink cartridges for extended periods after the cartridges are opened will oxidize and
degrade. Try to use up ink as quickly as possible after ink cartridges are unsealed.
Using degraded ink may result in problems that require the replacement of the print heads or
other ink-handling parts (misring nozzles).
* Precautions for anticipated periods of extended disuse
- Ink in the internal ink passages may degrade or dry out over the time, resulting in nozzle misres
and other problems. In the worst cases, misring nozzles will require replacing the print heads.
- To avoid these problems, we recommend operating the printer now and then.
* Precautions for use of the printer after long storage
- If print head cleaning is not performed before use, misring nozzles or other printing problems
may occur.
Start by checking for any misring nozzles.
- If the nozzles are misring, perform head cleaning.
In some cases, the head cleaning procedure will need to be repeated several times to clear the
print head nozzles.
- If the nozzle condition does not improve after the nozzles are checked for misring and strong

ComColor Series (Revision 2.4)
[ 1-6 ]
Maintenance
cleaning is repeated several times, the print heads may need to be replaced.
* Differences between display and print colors
- The colors on prints may differ slightly from the colors seen on your display device.
- The difference in the colors may be attributable to various factors, including differences between
RGB and CMYK color systems, the RIP color system, display device settings, etc.
* Never touch the surfaces of the print head nozzles.
- Scratching the print head nozzle surface or dust adhering to the print head nozzle surface may
cause printing problems. Never wipe the print head nozzle surface.
- In the worst cases (misring nozzles), such problems may require replacement of the print heads.
To prevent problems, avoid touching print head nozzle surfaces during machine maintenance. Be
careful to avoid scratching print head nozzle surfaces with tools or parts when working near the
print heads.
* Protect the print heads from any physical shock.
- The print heads are extremely fragile. Handle them carefully, and avoid dropping or striking them.
* Selection of paper type
- Use only the specied paper type. Using the wrong paper may result in poor adhesion of ink to
the paper.
- If you choose to use a paper product not specically recommended by the manufacturer, rst
perform a printing test. Papers producing paper dust will cause misres.
- Ink that fails to adhere to the paper may be left on the transport roller or transfer belt, smudging
subsequent prints.
- Internal parts contaminated by ink may require more frequent maintenance. To avoid these
problems, select your paper carefully.
* Maintenance of proper operating conditions
- Ink viscosity affects the ink ejecting performance of inkjet printers.
- Ink viscosity increases with lower temperatures, making ejection problems like nozzle misres
more likely. Use the printer only under the specied operating conditions.
* Cleaning wipe
- To wipe off ink from the printer, use the Kimtech or Kimwipe products manufactured by CRECIA
Corp. or similar dust- and ber-free materials. Never use ordinary tissue paper.
- Fibers and paper dust from cleaning materials may cause nozzle misres and other problems.
- Never wipe the print head (the head surface). Let the machine clean the head by itself.

1-3.Other precautions for inspection and maintenance
Precautions for inspections
* If a defect or abnormality is found during inspections, correct the problem and replace parts, if
necessary.
Precautions for parts removal
* When ascertaining the location of a problem, also determine the cause of the problem. After
determining whether it is necessary to remove parts or disassemble the machine, perform the
required repairs according to the procedures given in the technical manual.
* Watch for ink leaks when disassembling ink-handling components.
* Don't apply power beyond necessity with the ink tube junction. Moreover, work, being careful for
the ink tube junction not to disconnect accidentally.
* When disassembling a component consisting of many parts, similar parts or symmetrical right
and left parts, organize the removed parts to ensure proper reassembly.
1) Set aside and arrange removed parts.
2) Clearly identify which parts are to be replaced and which parts are to be reused.
3) When replacing screws or other fasteners, use only parts of the specied size.
Precautions for reinstallation and reassembly
* To reassemble or reinstall parts, follow the disassembly or
removal sequence in reverse, unless otherwise specied.
* If parts have protrusions and indentations for positioning
(half pierced), align them carefully to ensure proper installation.
* When you attach the ink tube, attach after wiping off nely,
when the inner side of the ink tube or ink tube junction is dirty
with ink.
Precautions for electrical work
* If bundled wires have come loose, use a cable tie or band to hold them together after nishing
the work.
* When installing parts, be careful to avoid pinching or damaging electrical wires.
* Replace blown or defective fuses with fuses of the specied capacity rating.
In addition to equipment damage, using a fuse with a rating above the specied value may result
in re.

Maintenance
1-4.Sensors
* Be sure to turn off power before disconnecting or connecting sensors.
Photosensor types
* In general, photo sensors can be divided into four types: the interrupt type (U-shaped), the
actuator type, the reection type, and the transmission type.
Magnetic sensor types
* Some magnetic sensors use Hall ICs, while others use magnetic reed switches.
Switch types
* Microswitches use either N.O. (Normally Open) contact or N.C. (Normally Closed) contact.
* The N.O. contact closes when the switch actuator is pressed.
* The N.C. contact opens when the switch actuator is pressed.
