7.0 Maintenance and Adjustments
Your Lemur-ERAM flight strip printer is solidly constructed and has been designed for high volume use. It
requires minimal care to provide maximum service.
WARNING: The appearance of this symbol indicates the proximity of an
exposed high voltage area. Please follow all directions carefully for your
personal safety. You must read the following safety information carefully
before working on the printer.
This section provides an overview of printer maintenance, including part alignments, adjustment and replacement.
For discussion purposes, the printer consists of three major modules or assemblies:
• Paper guide and print head assembly
• Cutter assembly
• Logic board assembly
As a safety precaution, all service to the printer should be done by qualified persons with
power off and the AC cord unplugged from the printer. Following any procedure requiring the
removal of covers and/or doors, please verify that they have been properly attached and
fastened prior to operating the printer.
7.1 Paper Guide and Print Head Assembly
The principal function of this assembly is to guide the flight strip stock to the thermal print head where thermal
printing takes place. Additionally, this assembly houses the drive platen and flight strip positioning sensors. If
necessary, the total assembly may be removed from the unit. All replacements and adjustments of the
components on this assembly may be done without removing the total assembly. The most common
adjustments and replacements regarding this assembly follow:
The above photo shows the cover removed from the printer. The cover is held onto the printer via Velcro and
may be removed by pulling straight up on the cover.

14
7.1.1 Cut Opto Assembly
There is one optical sensor (opto) mounted on an adjustable aluminum bracket. The opto controls
the cut or tear position. Removal or adjustment of the opto should be done without removing the
bracket from the paper guide. The opto position is factory set and adjustment should not be
necessary.
Note: Before making any opto adjustments make sure your ticket stock was manufactured to proper
ticket specifications.
To adjust the cut or tear position, physically adjust the opto mounting bracket forward or backwards to
achieve the desired cut or tear location. On a Lemur with auto cut the cut position should be a 1/16”-
1/8” away from the ticket perforation. On a Lemur without auto cut the ticket perforation should line
up with the edge of the cabinet or top plate.
Minor adjustments (no greater than 3/16”) to the cut or tear position may also be done via the control
panel by changing the INC/DEC CUT1/2 settings. (See 6.0 Control Panel Options). For this printer
the INC value should not exceed 55. Going beyond these values will cause reliability issues.
If you are not able to get the desired cut position, make sure your ticket stock was manufactured to
proper specifications.
Once a year the opto eye should be blown off with air. This interval will vary depending upon the
environment and the quality of the ticket stock.

7.1.2 THERMAL PRINT HEAD
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 following needs to be done with the printer powered off and unplugged from the AC source.
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 plate) to remove pressure from the thermal
head.
4. Position the cam lock level as far forward as possible.
5. Flip the head back toward the rear of the printer. Denote what slot the print head was taken out of. Below photos
show the different type of head mounting plates used through the production history of the Lemur series printers.
Cam Lock
Lever

6. Lift the print head mounting plate straight out.
7. Clean the thermal print head surface (the side that makes contact with the paper) with isopropyl alcohol & paper
towel.
8. Install the head mounting plate by reversing the above procedures. Make sure the print head mounting plate tabs
are in the back slot of the print cage slots.
9. Restore pressure to the head by pushing down on the cam lock assembly.
10. The printer in now ready for operation. If the print quality is still poor then the thermal head needs to be replaced.

7.1.3 THERMAL PRINT HEAD REPLACEMENT
The following is done with the printer powered off and unplugged from the AC source.
1. Remove the print head mounting plate from the printer (Refer to section 7.1.2 THERMAL PRINT
HEAD).
2. Once the head plate has been removed; loosen the two Philip head screws until the thermal print head
disengages from the head plate. Take care not to lose lock and flat washers.
3. Gently unplug the cable from the old print head and plug it into the new print head. If your print head
has two cables then this should be done one cable at a time so not to mix them up. The cables are
keyed (see examples below). The keyed position must be lined up while plugging the cable into the
print head. You should not have to use excessive force to do this.
4. Install the print head back onto the print head mounting plate.
5. Install the head mounting plate/ thermal head back into the printer.
