RIBBON SENSOR ADJUSTMENT

This sensor adjustment regulates penetrating ability for ribbon feed. Penetration modification is performed via a potentiometer that is part of the potentiometer complex located behind the access panel on the left side of the printer.

To establish the penetration level, upper and lower limits must be set. 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 sold by SATO America. Refer to the procedure below for directions using the test module.

NOTE: Refer to the RIBBON REFERENCE CHART table above for the assigned potentiometer to be adjusted for to the media used. The table also identifies the relative test module dial setting and the lower and upper limit multimeter requirements.

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

2 Load the printer with ribbon stock.

3 Connect the test module to the available test connector.

4 Connect the multimeter ground probe to the pin identified as GRD on the test module. 5 Connect the multimeter positive probe to the pin identified as SIG

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

7 Rotate the ribbon supply spindle to align one of the slots with the sensor eye. 8 Adjust the relative potentiometer to the required multimeter reading.

9 Rotate the ribbon supply spindle to align one of the tabs with the sensor eye.

10Regard the multimeter reading to determine the difference or upper limit.

11Repeat steps 6 through 10 until the required difference is achieved.

12Begin 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. Refer to the table above to correlate the desired adjustment function with its relative connector pin. Refer to Figures 6-11 and 6-12 for guidance.
