This explains how to check DC power supply, I-Mark
sensor level, Gap/center hole sensor level, ribbon sensor
level, side hole sensor level, R-corner hole sensor level
and jump hole sensor level. Ensure printer power is OFF.
Then remove the VR cover on the back of the printer and
perform the following steps.

STEPS

1 Attach the connector from the TP T est Module to the

test port on the MAIN PCB. Note correct positioning
of connector. Nibs on the connector are placed down
on the PCB in the forward position.

2 Attach the ground probe of the Digital Multimeter to

the TP T est Module ground pin (GND PIN).

3 Attach positive probe of the Multimeter to the +SIG

PIN on the TP Test Module terminal.

4 Turn printer power on and rotate the dial to a dial

POS on the TP T est Module. Record the values from
the Multimeter.

5 Confirm voltages are corre ct. If not, then replace

parts or adjustment sensor level. Refer to Check and
Adjustm ent chart.

6 Afte r performing test, pu t the VR cover back to

the printer.

Low level (Set the no eye-mark point

in the sensor’s) = Less than +0.5V

High level (Set the eye-mark in the sensor’s)

= Low level plus more than +0.9V

High level (with eye-mark point) - Low level

(without eye-mark point) = +0.9V

Low level (S et the label backing liner or centre

hole tag in the sensor’s)

High level (Set the label and tag in the

sensor’s) = Low level plus more than +0.1V

High level (printing point) -

Low level (gap point) = +1.0V

= Less than +0.5V

(VR2 is used for adjusting the

light reception flow. If there is

difference between the high and

low level, adjust VR2 to allow

some level difference.)
