4.4 Ribbon Rewind Spindle Encoder Replacement

The encoder is installed on the gear box of DC motor, and is used to detect if the ribbon

is unerringly rewound by the spindle. The encoder is connected to JP6 on the

mainboard. Please switch the printer to thermal transfer mode. The multi-meter is used

to measure the voltage of Pin2 (+5V). If the voltage changes continuously from 0 to 5

volts DC, the encoder is in condition. Otherwise, please follow the steps below to

replace the encoder PCB.

2. Remove the two flat tap screws and cable tie.

3. Replace the Encoder PCB.
