CLEANING THE PRINT HEAD AND PLATEN CL408e and CL412e
Supplies needed: SATO SA070 Cleaning Kit
Cleaning the Print Head
1. Turn the printer off and
remove the power cable
and open the Top Access
Door.
2. Open the Print Head
Assembly by rotating the
green Head Latch
counter-clockwise. The
Print Head Assembly is
spring-loaded and will
automatically open as
soon as the Head Latch
is disengaged. Remove the
ribbon.
3. Apply SATO 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 (you may
need to move the ribbon out of the way to do this).
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 ribbon is changed and more
often in harsh environments.
Cleaning the Platen
1. Turn the printer off and remove the power cord.
2. Open the Print Head Assembly by rotating the green Head Latch
counter-clockwise. The Print Head Assembly is spring-loaded and will
automatically open as soon as the Head Latch is disengaged. Remove the labels.
3. Apply SATO Thermal Print Head Cleaner to one of the cotton swabs.
4. The Platen is the rubber roller directly below the Print Head. It should be
cleaned of any ribbon or label residue.
5. Repeat if necessary. The platen and rollers should be cleaned whenever foreign
matter such as dust or adhesive is present.
