Inkjet printer TxF150-75/TxF300-75
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.

Performing Maintenance
Maintenance should be performed regularly or based on how often the machine is used, in order to maintain printing accuracy
and ensure long-term use.
This is a precision machine with extremely delicate mechanisms. In particular, the head nozzle surface from which ink is
discharged may be affected by even the slightest amount of adhering dust or paper dust, which may prevent achieving optimal
printing results.
To keep the machine operating in good condition, we recommend the following routine maintenance.

Examples of Printing Issues
The following are typical examples of head (nozzle) ejection failure caused by dust or other factors that affect printing. To avoid
using the nozzles in this state, check the nozzles regularly before and during printing. Nozzle status can be checked by using the
machine's test printing function.
Recovering from nozzle ejection failure
If the machine is idle over an extended period, or under certain ambient temperatures, discharging from nozzles may become
unstable. The following nozzle recovery is available.
For symptoms in figures 1–4 above
1. Routine maintenance
Clean the areas described in this manual.
2. Perform head cleaning (normal/hard)
If the nozzle dropout does not recover after repeating the normal cleaning
several times, perform the hard cleaning.
Check results of test printing
If this does not alleviate nozzle clogging or other issues
3. Perform an ink filling (normal or hard)
If it does not recover with cleaning, perform normal or hard cleaning. Check results of test printing
If this does not alleviate nozzle clogging or other issues
4. Wash the head nozzles
Perform head nozzle washing. Set the leaving time for head nozzle immer-
sion in maintenance liquid to one minute.
Check results of test printing
If this does not alleviate nozzle clogging or other issues
5. Wash the head nozzles again
Set the leaving time for head nozzle immersion in maintenance liquid to 10
minutes.
