Routine Cleaning
Printer parts accumulate residue, especially those in direct contact with the
thermal transfer ribbon. To maintain clear, crisp printing, clean the printer
regularly. Cleaning after using a full roll of thermal transfer ribbon is
recommended.
To clean the printer:
1 Remove the printhead cams and the drive roller cam by flipping each
cam open to relieve pressure. Do not lock printheads into the up
position.
2 Press the silver clip holding each cam, pull the cam completely out, and
set aside.
1. Silver retaining clip 3. Cam lever
2. Outer thumbwheel
3 Remove any label media and thermal transfer ribbon from the print path.
4 Use a cleaning pad, a cotton swab, or a soft lint-free cloth wet with
isopropyl alcohol and run it on underside of each printhead, especially
on the hairline rows of print elements and along the edge of the struts.
5 Also clean the platen rollers, guide rollers, film guide shafts, pressure
rollers, and drive rollers.
