•
Are there fingerprints on the printing surface?
→
Especially when cut media is being mounted, oil from the skin may be transferred to the printing surface causing poor adhesion of ink
printed at such places. Care is needed when mounting the media.
•
Are the ink cartridges past their effective limit?
→
The shelf life of an ink cartridge is two years after manufacture if unopened, six months after opening. Using out-of-date cartridges leads
to head blockages.
❈
Replace with new cartridges.
•
Is media recommended by Mutoh being used?
→
If the media is causing the symptoms, and it is not recommended media, the results cannot be guaranteed. Please use recommended
media.
•
Was the printing done immediately after initial filling?
→
Wait at least 30 minutes after initial filling before printing. Otherwise printing quality can not be guaranteed.
•
When there are satellites, whiskers, blurring, etc. in the printing, first check the following two points:
1. Is the test pattern printed normally? (Refer to PAT1000)
→
Carry out a cleaning if there are breaks in the printing of the nozzle check pattern.
2. Was cleaning done three times in succession?
→
For details of how to clean, refer to “Direct Key Explanation” in the Operation Manual.
•
If the symptoms occur after cartridges have been replaced or after cartridges have been removed and re-installed, check whether any of
the following items apply:
1. Ink cartridges are kept in a cool, dark place but they will freeze if they are stored for a long time below -18°C. Avoid storage below
freezing point.
If the ink has frozen, leave it for at least three hours at room temperature (25°C) and use it after it has thawed.
2. The seal should not be opened until just before the ink cartridge in inserted in the slot. If an ink cartridge has been left unsealed for a
long time, the printing will be faint and cleaning will be required.
3. An ink cartridge should be removed and reinserted until "No Ink" is displayed otherwise normal printing may not be possible even
though there is ink remaining in the cartridge.
If it is removed and re-installed, cleaning will be needed and for recovery it may be necessary to replace the cartridge with a new one.
4. If a cartridge has been brought from a cold place into a warm place, dew may condense on the cartridge and it will need to left for at
least one hour until the dew has disappeared before it is used.
•
Is the printer installed within the guaranteed working temperature range for the print head, as stated in the Operation Manual and has that
environment been maintained in a stable condition for two hours?
→
It may not be possible to obtain good printing results in an environment which is outside the guaranteed working temperature range or
where there is a sudden rise or fall of temperature.
Check the environmental conditions and try again within the specified range.
