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
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
