JUMP HOLE SENSOR ADJUSTMENT

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.

Perform the steps below using the test module and refer to Figure 6-11 for visual assistance.

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

2Adjust the VR7 and VR11 potentiometers fully counter clock-wise.

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 7 position.

7Physically place side hole media’s reference point over the jump sensor.

8Adjust the VR7 potentiometer until the multimeter displays a value less than +0.5V.

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

10Regard the multimeter to determine the second measurement is greater than +2.0V.

11Repeat steps 6 through 10 until a minimum difference of 1.5V is achieved.

12Connect the multimeter positive probe to TP3 connector and the negative probe to TP4.

13Adjust the VR11 potentiometer so the multimeter display indicates a nominal voltage value.

NOTE: The VR12 potentiometer establishes the threshold value which is the nominal value (midway between the lower and upper values).

14 Begin 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 5B. Refer to Figures 6-11 and 6-12 for visual assistance.
