• 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.
• 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The use of out-of-date ink cartridges leads to head blockages.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.
• 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.
• Are there fingerprints on the printing surface?
→
If oil from the skin is transferred to the printing surface, especially when cut media is being mounted, this may cause
poor adhesion of ink when printing at those places. Care is needed when mounting the media.
• To which printing mode, high quality/normal/high speed, and to which resolution, 360/720 dpi, does this apply?
→
Since image quality will be inferior at high speed and 360 dpi due to their relationship with the plotting pass, please try a
different mode.
• Is the pressure lever fully down?
→
Lower the pressure lever completely.
• In the case of roll media, is the roll shaft housed properly in both the left and right printer shaft support rollers on the main
unit?
→
If it not housed properly, the media will not be fed normally, causing the media to float up and white and black lines to
appear.
• Has the fine adjustment of image quality been made?
→
The fine adjustment of image quality should be made if printed horizontal lines are slipping in the direction of the media
feed, or there is a gap between black and other colors.
• Is the type of media that is being used the same as the type of media that was specified with the printer driver?
→
The printing quality will be affected if the type of media that was specified with the printer driver is not the same as the
type of media that is being used.
Make sure the specification agrees with the type of media that is actually being used.
