PAPER GUIDE SLIDER BAR
Confirm that the slider bar on the paper path is properly adjusted for the width stock being used. If
the slider bar is adjusted too far away from the ticket it may cause crooked printout or the printer to
skip tickets.
To adjust the paper path for use with a different ticket width, adjust the slider bar to the fully open position.
Insert your ticket stock into the paper guide. Adjust the slider bar down to the proper ticket width, making sure
the bar is not too tight against the ticket. The ticket should move freely in the paper guide.
The slider bar would be Slider Bar. Stock must go

The following is done with the printer powered off and unplugged from the AC source.
THERMAL PRINT HEAD CLEANING PROCEDURE
The print head should be cleaned periodically to prevent debris from building up on the print element. The
required cleaning interval varies greatly depending on the quality of the ticket stock and the amount of dust
entering the print area. Excessive dirt build up on the print head will result in reduced quality. Continuing to
run the print head in a dirty condition will reduce its life expectancy, as it is unable to diffuse its heat properly.
The thermal print head can be removed for cleaning or replacement, as follows:
1. Make sure power is off and the AC cord is disconnected from the printer.
2. DO NOT UNPLUG CABLE FROM PRINT HEAD.
3. Lift up on the cam lock assembly (located above the head mounting block or plate) to
remove pressure from the thermal head. Photo A
4. Lift up on the head mounting plate/thermal head to remove. Photo B
5. Clean the thermal print head surface (the side that makes contact with the paper)
with isopropyl alcohol. Photo C
6. While the print head is removed move forward with cleaning the platen and load opto (if present).

PLATEN CLEANING PROCEDURE
The Platen (rubber drive roller) should be cleaned once a year to prevent paper dust from building up on the
roller. (NOTE: The platen may require more frequent cleaning in dusty environments or when using inferior
ticket stock.)
1. With the print head still removed, clean the platen.
2. Apply a small amount of Isopropyl alcohol onto a paper towel to clean the rubber roller.
3. Clean only the part of the rubber roller where the ticket stock makes contact with.
4. Rotate the rubber roller clockwise a little and repeat step 4; continue in the same manner for one full
revolution of the rubber roller.
5. Move onto cleaning the SQ load opto if the printer has one.
Platen
Platen size may vary from what is shown in the photo.
Clean SQ Load Opto if printer has one
A printer built after August 2014 may have a load SQ opto that is responsible for letting the printer
know when it has paper stock loaded in the printer. Printers with s/n 310327 or higher.
1. Using inert dusting gas (canned air) or equivalent blow air over the opto eyes (see photo
below).
2. Once the opto eye is cleaned, install the head by reversing the steps that was done The
Thermal Head Cleaning Procedure Section.
3. Restore pressure to the head by pushing down on the cam lock lever.

OPTICAL DEVICES CLEANING PROCEDURE
Blow air in this area
Above image is of a standard 422264 opto Above image is of a SQ opto
There is one optical device (opto) mounted on a black plastic bracket beneath the paper guide. The
opto controls ticket cut/tear position. Over a period of time there may be an accumulation of ticket
dust on the opto eyes themselves. This paper dust could cause erratic operation of the printer.
1. Using inert dusting gas (canned air) or equivalent blow air over the opto eyes (see above
diagram).
The printer is now ready to be put back in service.
