11.6 Cleaning the Print Head and Platen
Use the following procedure to manually clean the print head:
11.6.1 Toggle the power switch to
O
(OFF) and disconnect the power cord from the rear of the Unit.
CAUTION
Take caution when opening the left side door. Refer to “Installation” section
for details on how the left door opens and the space required.
11.6.2 Unlock the door on the left side of the Unit and swing it open.
11.6.3 Back the ticket card stock all the way out of the transport mechanism.
11.6.4 Dampen a foam swab in a 99% Isopropyl Alcohol cleaning solution and apply it to the flat burn-line surface area of
the print head. This is the area that normally contacts the print head platen. Move the swab back and forth across
the print head until it is clean.
11.6.5 Dampen a lint-free cloth with a 99% Isopropyl Alcohol cleaning solution.
11.6.6 Hold the cloth firmly against the print head platen while using your other hand to turn the knurled knob in a
clockwise direction. While holding the dampened cloth against the platen, gradually move it back and forth across
the width of the platen, cleaning the entire platen surface. The cloth will be discolored from the dust buildup on the
platen.
11.6.7 Dampen another area of the cloth and repeat this process until the cloth no longer discolors. This will indicate the
platen is clean.
11.6.8 After all cleaning is complete, plug the power cord back into the rear of the Unit, toggle the power switch to
I
(ON),
and reload the ticket stock. Refer to the “Basic Unit Operation and Setup” section.
