PITCH SENSOR ADJUSTMENT (EYE-MARK MEDIA)

Unit 6: Maintenance

PITCH SENSOR ADJUSTMENT (EYE-MARK MEDIA)

This sensor adjustment regulates penetrating ability for media referencing. Penetration modification is performed via two potentiometers that is part of the potentiometer complex located behind the access panel on the left side of the printer.

To establish penetration, upper and lower voltage levels must be set and the difference between the two voltage levels should be maximized for optimum performance.

These activities require the use of a multimeter and may be perfomed with or without the assistance of the SATO Test Module. The test module is a purchase option..

Refer to the procedure below for directions using the test module and Figure 6-11 for visual assistance.

1 Detach the access panel located on the left side of the printer.

2Adjust the VR8 potentiometer fully counter clock-wise and the VR2 adjusted center scale.

3Connect the test module to the available test connector.

4Connect the multimeter ground probe to the pin identified as GRD on the test module.

5Connect the multimeter positive probe to the pin identified as SIG.

6Turn the printer on and rotate the test module dial to the 4 position.

7Physically place the media’s reference point over the pitch sensor.

8Adjust the VR8 potentiometer until the multimeter displays a value less than +0.5V.

9Relocate the media so the paper portion is oriented over the pitch sensor.

10Regard the multimeter to determine the second measurement is greater than +1.5V.

11Use the VR8 potentiometer for fine adjustment as necessary.

12Repeat steps 6 through 11 until the required difference of 0.9V is achieved.

13Begin normal printing to ensure proper adjustment.

Multimeter Alone

Sensor adjustment may be performed by using a multimeter without the assistance of the test module. To perform this task the multimeter probes must be attached to the correct connector pins of the test connector. Connect the multimeter positive probe to pin 1A and the negative probe to pin 2B. Refer to Figures 6-11 and 6-12 for visual assistance.
