Removal and Installation - Encoder Disk and Encoder Sensor

Encoder Disk and Encoder Sensor

The only differences between the T1120/T620 and T1100/T1100ps/T610 service parts is the

cable connection and analog encoder pca.

Removal

1. Remove the Left Cover on page 6-30.

2. Remove the Electronics Module Main PCA

and PS

U. See page

6-202or 6-205

depending on the printer model.

3. Remove the

Left Spittoon on page 6-214.

4. Remove the Encoder Disk straight off

Media Advance Roller spindle, lift it

straight out of the printer.

The Media Advance Roller

spindle is delicate. Remove the

Encoder Disk gently.

Switch off the printer and remove the power cable.

If you have a T1120/T1120ps, never replace the Encoder Disk and Encoder

Sensor at the same time as the Formatter/Hard Disc Drive. If you must

replace both parts, always replace one, restart the machine, and then follow

the procedure to replace the other.

If you have a T1120/T1120ps, never use a previously used Encoder Sensor

PCA. This can cause serious problems, and may make the printer unusable.

For more information, refer to page Replacing the PrintMech PCA, Media Advance

Encoder PCA and Formatter on page 2-3.
