Use the following procedure to manually clean the encoder drive rollers:
11.5.1 Toggle the power switch to

(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 and right side doors open and the space required.
11.5.2
Unlock the door on the left side of the Unit and swing it open.
11.5.3
Back the ticket card stock all the way out of the transport mechanism.

Dampen a lint-free cloth with a 99% Isopropyl Alcohol cleaning solution.
11.5.5
Hold the cloth firmly against one of the bottom drive rollers with one hand while turning the knurled knob
clockwise with the other. Turn the knob a few times and remove the cloth. The cloth will be discolored from the
dust/ink buildup on the roller.

Dampen another area of the cloth and repeat this process until the cloth no longer discolors. This will indicate the
roller is clean. Repeat until all bottom drive rollers are cleaned.

knurled knob clockwise with the other. Turn the knob a few times and remove the cloth. The cloth will be
discolored from the dust/ink buildup on the roller.

Dampen another area of the cloth and repeat this process until the cloth no longer discolors. This will indicate the
roller is clean. Repeat until all top idler rollers are cleaned.
