• Ink cartridges may contain dye inks or pigment inks. Each type of ink comes in four colors. Are they all genuine Mutoh car-
tridges?
→
Replace them with genuine Mutoh ink cartridges.
• Are the ink cartridges past their effective limit?
→
The effective life of an ink cartridge is two years after manufacture if unopened, or six months after opening.
The use of out-of-date ink cartridges leads to head blockages.
❈
Replace with new cartridges.
• Cartridges must be inserted in the right direction. Are they mounted correctly?
→
Check the direction and mount them correctly.
• Are the ink cartridges pushed right to the back?
→
Make sure they are inserted properly.
• Is media recommended by Mutoh being used?
→
No guarantee can be given if the media is causing the problem and it is not media recommended by Mutoh. Please use
media recommended by Mutoh.
• Does cleaning restore normal operation?
→
Carry out two successive cleanings.
• Is printing being done immediately after initial filling?
→
On rare occasions, printing immediately after initial filling may produce unstable printing quality.
In that case, wait for at least 30 minutes with the power switched off before printing again.
• If the symptoms occur after cartridges have been replaced or after cartridges have been removed and reinstalled, check
whether any of the following circumstances 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 stor-
age 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 is 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 not be removed from the slot and reinserted until "No Ink" appears and it is to be replaced.
Otherwise normal printing may become impossible even though there is ink remaining in the cartridge.
If a cartridge has been removed and reinstalled, cleaning will be needed and for recovery it may be necessary to replace
the cartridge with a new one.
4. If dew has condensed on a cartridge that has been brought into a warm place from a cold place, leave the cartridge for
at least one hour at room temperature until the dew has disappeared before using it.
