STEP PROCEDURE
Refer to Section 4-2 for access to main PCB
1. Connect the power cable. Raise the main cover and load the ribbon and
label stock. Fig. 9-41
2. Turn the power to the ON position.
3. Set the VR2 potentiometer on the main circuit board fully clockwise.
Fig. 9-42 & 9-43
4. Set the digital multimeter to DC voltage measurement mode.
Connect (+) probe of the multimeter to test pin CH8 and the lead from
the (-) probe of the multimeter to test pin labelled CH1 on the main
circuit board. Fig. 9-44 & 9-45
5. For Low level (Label Gap part) adjustment, put label gap part in the pitch
sensor. Then adjust the electrical level with VR2 on the main PCB so that
it will measure +0.8V .
6. For High level (paper part) adjustment, put paper part in the pitch sensor
and check the electrical level. If the level difference is +2.0V more than
the Low level, it is acceptable. If not, return to STEP 5 and readjust.
7. Standard values: Low level (gap or hole part): +0.8V .
High level (paper part): Low level +2.0V or higher
than low level.
If these values do not result, try the following:
a) Repeat the process
b) Clean the sensor
c) Replace the sensor
Additional equipment required: Digital Multimeter
