4.4.3.2 PF Loop Scale ASSY Affixing Procedure

When assembling the PF loop scale unit, the following exclusive tool should be used.
Exclusive tool No.#F731
The assembly procedure is given below.
1. Set the PF loop scale ASSY's double sided tape side on the grid roller side, align the
internal diameter of the PF loop scale with the left end of the grid roller (PF roller) and
set it lightly.
At this point, the PF loop scale ASSY should not be fitted on the
C A U T I O N
grid roller as far as it can go. If the PF loop scale ASSY is placed on
the grid roller by hand, it could damage the PF loop scale ASSY's
internal diameter and the distance from the center of the grid roller
to the scale reading part would not be the same all around any
more, resulting in a drop in the encoder sensor's reading accuracy.
2. Press the exclusive tool #F731 against the PF loop scale ASSY from the outside, then
insert the grid roller in as far as the base plate carefully, and affix it.
