Requests for Care and Maintenance
This machine is a precision machine equipped with extremely fine mechanisms. Especially, the nozzle surface of the heads from
which the ink is discharged is affected even by a slightest attachment of dust or paper powder and the proper printing results
could not be obtained. With a view to using this machine in a better condition, we would like to recommend performing the
following care and maintenance on daily basis.
Maintenance Precautions
• This machine includes parts that must be replaced periodically. We therefore recommend taking out a maintenance
contract. Carry out maintenance periodically and replace consumable items to prevent quality defects and
accidents.
• Clean periodically. Debris and dust will accumulate on electrical components when the machine is used for
extended periods. There is a risk of failure, electric shock, or fire due to current leakage.
• Do not clean by blowing—e.g., avoid using air blowers. Doing so may lead to failure, electric shock, or fire involving
the machine if airborne debris or dust gets inside electrical components. Wipe using a soft cloth soaked in diluted
neutral detergent and thoroughly wrung out. A vacuum cleaner may also be used for cleaning.
• Do not allow liquids to get inside the machine. Otherwise there is a risk of failure, electric shock, or fire.
• For heavy soiling, wipe using a soft cloth soaked in diluted neutral detergent and thoroughly wrung out.
• Pay close attention to ventilation and be sure to wear safety glasses, gloves, and a mask when handling ink,
maintenance liquid, waste ink, or other solutions used with the machine. Leaking ink may adhere to the skin or get
into the eyes or mouth.
• Never touch the print head nozzle surface. Do not allow water or alcohol to come into contact with the print nozzle
surface. This will increase the risk of machine failure or ejection failures (e.g., nozzle clogging or deflection).
• Do not use cotton swabs to clean around the head or carriage. Fibers from cotton swabs may adhere to the head
nozzle surface and lead to ejection failures (e.g., nozzle clogging or deflection).
• Do not splash ink or maintenance liquid on the covers. Exposure to splashing ink or maintenance liquid may
damage or deform the cover.
• Do not use benzine, thinner, or any chemical agent containing abrasives. Use of these chemicals may result in
damage to or deformation of parts.
• Do not move the carriage by hand. To move the carriage, use the carriage out function on the menu.
