Part 7 Troubleshooting
- When faint vertical lines of grime are visible in the blank
areas of the media when continuous printing is performed
Depending on the media, heat may build up in the printing
heads, making ink prone to sticking to blanks areas outside the
printed areas. If this happens, switch off the machine and open
the front cover for about 30 minutes to allow heat to dissipate.
- Are the cleaning pads dusty or damaged?
If the cleaning pads become dust or damaged, they may destroy
the printing heads. Clean away any adhering dust or grime. If the
cleaning pads are damaged, immediately replace them with new
cleaning pads.
See -> "6.1 Cleaning" - "Cleaning the Cleaning Pads"
- Have the cleaning pads deteriorated?
Continuing to use degraded cleaning pads may impair printing
quality. As a general guide, replace the cleaning pads with new
ones after around 50 meters of roll media have been printed.
See -> "6.1 Cleaning" - "Cleaning the Cleaning Pads"
- Is the media dirty?
Does the media show printing grime, dust, scratching, or
the like?
Dust or scratches on the dust of the media or perspiration or oils
transferred to the media during handling can cause printing to be
absent or blurry, making attractive printing impossible.
If the media is dirty, then before you load it on the machine,
clean it using rubbing alcohol.
When you load the media after cleaning it, be careful not to let
any soiling adhere to the printing area.
Also, media that is dusty or scratched may not only make
attractive printing impossible, but may even damage the printing
heads. If media becomes damaged, replace it with fresh media.
Be careful to keep media from becoming dusty or damaged
during storage.
- Are you using media that has been allowed to become
sufficiently acclimatized to the environment?
The media absorbs moisture from the air, making it expand or
contract. Printing may be misaligned if the media expands or
contracts during operation.
Pull out from the roll media the length of media you intend to
use, then allow it to stand for about 30 minutes to an hour. The
time required to acclimatize to the environment varies depending
on the type of media.
- Was a used-up ink ribbon turned upside down or
rewound and reused?
Once an ink-ribbon cartridge has been used up, you cannot turn
it over or rewind the ink ribbon and reuse it. Replace with a new
ink-ribbon cartridge.

- Are the ink-ribbon cartridges installed correctly?
Correctly install the ink-ribbon cartridges in the ink-ribbon
cartridge holders. Also, looseness of slack in the ribbon can
impair attractive printing.
See -> "3.3 Installing Ink-ribbon Cartridges"
- When color darkness is different after changing an ink-
ribbon cartridge
Ink-ribbon cartridges may show slight variations in color. When
you replace an ink-ribbon cartridge while printing in progress,
the deepness of the color after changing the ink-ribbon cartridge
may be different.
- During printing, did the ink ribbon in the ink-ribbon
cartridge installed in the carriage become slack and come
loose from the printing heads?
The ink-ribbon cartridge returns to the ink-ribbon cartridge
holder when you stop printing and turn off the machine, so
reinstall all the ink-ribbon cartridges. When you do this, take up
any slack in the ink-ribbon cartridges before you install them. If
the problem occurs with a particular color, replace it with a new
ink-ribbon cartridge.
An ink-ribbon cartridge doesn't leave the
carriage.
When printing finish, the ink-ribbon cartridge normally returns
from the carriage to the ink-ribbon cartridge holder.
The [error] light flashes if an ink-ribbon cartridge remains in the
carriage for some reason after printing ends. If this happens,
follow the steps below to remove the ink-ribbon cartridge from
the carriage.
1
Press the [power] button to turn off the printer.
2
Press front-cover eject button and open the front cover.
3
Remove all ink-ribbon cartridges from the five ink-ribbon
cartridge holders.
4
Close the front cover.
5
Press the [power] button to turn on the machine. When the
power comes on, the machine performs the operation to return
the ink-ribbon cartridge in the carriage to the ink-ribbon
cartridge holder. The [power] and [ready] lights illuminate
when it returns normally.
* The [error] light flashes if the ink-ribbon cartridge does not
return to the ink-ribbon cartridge holder.
6
Press the front-cover eject button and open the front cover.
7
Check to make sure the ink-ribbon cartridge that was in the
carriage is now in the ink-ribbon cartridge holder.
