(23)If the PF encoder disk needs to be replaced, peel it off from the PF roller gear L.
Note: Once removed, the PF encoder disk will become unusable and a new disk will have

Performing steps (24) through (28) requires removing the PF encoder disk, so make a new disk
ready for use.

Assembling Note: When attaching the PF encoder disk to the PF roller gear L, using a spatular
tool makes the job easier. Put on clean gloves to protect the disk surface from dust or
fingerprints.
