SATO 10e service manual Ribbon Sensor Replacement

Section 7: Replacement Procedures

NOTE: It is recommended that the screw be applied to the sensor board and held into place with the driver using one hand. Align the screw with the mounting orifice while looking through the glass window from above. Focus on getting the screw started without consideration of the sensor board’s orientation. Once the screw is started, the sensor board may be properly positioned and the screw tightened.

NOTE: A properly oriented sensor will be mounted so that the screw is on the left end of the board, the connector is oriented downward, and the two sensor eyes may be seen through their respective ports in the rack plate.

12Connect wiring harness (A) to sensor connector (A).

13Apply left guide plate (4) to rack plate (5) and secure using thumbscrew (3).

NOTE: When repositioning the left guide plate for mounting, ensure that it is inserted under the stay bar across the rear of the printer.

14 Install media and test cycle to ensure a proper function.

NOTE: Figures 10-1 and 10-2 of the Diagrams & Schematics section provides guidance on housing cover and media installation.

15Secure stay bar (2) to printer frame using two screws (1) on each end.

16Install right, left, front, and top housing covers.

RIBBON SENSOR REPLACEMENT

The ribbon sensor detects the depletion of ribbon supply by monitoring the movement of a toothed wheel facing the sensor eye. The sensor is located behind the right housing cover and secured to the exterior of the ribbon spindle bracket. Refer to Figure 10-4 of the Diagrams & Schematics section of this manual for a visual image of sensor location.

1Switch off the printer and disconnect the power supply cord.

2 Remove the top, front, and right housing covers.

NOTE: Figure 10-1 of the Diagrams & Schematics section provides guidance on housing cover removal.

3Remove screw (1, Figure 7-18) securing sensor (2) to ribbon bracket (3).

4Disconnect sensor wiring harness (A) from sensor connector (A) on sensor (2).

5Connect sensor wiring harness (A) to replacement sensor connector (A).

6Secure replacement sensor (2) to ribbon bracket (3) using screw (1).

NOTE: A properly installed sensor will be oriented so that its sensor eye faces the white plastic toothed wheel when the mounting orifices are aligned.
