Cleaning
To maintain print quality and prolong the printer’s life, you need to perform some
routine maintenance. Daily maintenance should be done for high volume printing,
and weekly for low volume printing.
Warning
Always turn off the printer before cleaning.
4.1.1
Printhead
It is essential to keep printhead clean if you want the best print quality. We strongly
recommend that you clean the printhead when you load a new media roll. If the
printer is operated in critical environment, or the print quality declines, you need to
clean the printhead more frequently.
Keep in mind these things before you clean:
Keep the water away in case of corrosion on heating elements.
If you just finish printing, wait until the printhead cools down.
Do not touch the printhead with bare hands or hard objects.
Cleaning steps:
1.
Moisten a soft cloth or a cotton swab with ethyl alcohol.
2.
Gently wipe the printhead in one direction. That is, wipe it only from left to right
or vice versa. Do not wipe back-and-forth, in case dust or dirt attaches to the
printhead again.
Note
Printhead warranty becomes void if printhead’s serial number is
removed, altered, defected, or made illegible, under every circumstance.
