CLEANING THE PRINT HEAD, PLATEN AND ROLLERS
Cleaning the Print Head
1. Before starting, get ready an approved cleaning kit from your
SATO dealer or the kit supplied with the printer. Make sure the
printer is OFF, and remove the power cable.
2. Lift up the Top Cover and locate the Print Head Assembly which
is mounted under the cover.
3. Apply Thermal Print Head Cleaner to a cotton swab.
4. The Print Head faces downward along the front edge of the
assembly. Pass the end of the dampened swab along the entire
width of the Print Head.
5. Check for any black coloring or adhesive on the swab after cleaning.
6. Repeat if necessary until the swab is clean after it is passed over the head.
7. The head should be cleaned at least every time the label roll is changed, and more often in harsh
environments.
Clearning Stubborn Debris on the Print Head
1. If certain stains on the print head cannot be removed easily with
cotton swabs dabbed in cleaning solution, obtain cleaning
sheets designed for cleaning print heads (for such supplies,
contact your SATO dealer).
2. Load the cleaning sheet with the rough side facing the print
head. Follow any other instructions or precautions printed on
any leaflet that may accompany the cleaning sheet.
3. With the printer turned OFF, and the Top Cover closed, slowly
pull the cleaning sheet outwards. Repeat the process until the
print head is clean.
