This chapter describes routine cleaning procedure.

4.1 Cleaning

To maintain print quality and prolong the printer's life, you need to perform
routine maintenance. Daily maintenance should be done for high volume
printing, and weekly for low volume printing. Use a cleaning kit to clean the
printer regularly. You can purchase a cleaning kit from a SATO reseller or
technical service center.
Caution: 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 will 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 finished 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 Isopropyl alcohol (≥99%).
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.
