Procedure 3b – Routine Maintenance
Figure 7
a) After every 1,000ft. roll of ribbon, clean the printhead with isopropyl alcohol and a
cotton swab. Open the printhead via the printhead latch, lower the access door, and
insert the swab from the side. Run back and forth across the printhead surface
completely five (5) or more times to ensure that the printhead is properly cleaned.
o To reduce the amount of cleaning required and prevent unnecessary wear on
the printhead, it is advisable to store heat shrink tubing and ribbons in their
original boxes with their plastic sheeting, if applicable. This will prevent dust
and debris from gathering on the material and damaging the printhead.
b) When performance of the cutter begins to affect printing, refer to Procedure 2a to
inspect, rotate, or replace the cutting block and cutting blade as needed. It is
advised to change out the cutting block after a maximum of four (4) rotations,
cutting on each side and rotating end to end for an additional two times per side as
needed.
Be aware of the following safety protocols:
1. Never operate your SumiMark printer without the clear plastic Cutter Guard in place
2. Never attempt to insert any foreign object into the printer not necessary for printing
3. Always unplug your unit prior to performing any maintenance
4. Always operate the unit with the Tubing Cover closed
5. Never attempt to hold or move tubing as it travels through the printer
6. Ensure that the printer is always connected to a power surge protection system
