Note on reassembling:
• Media-path left-edge alignment when assembling the Plate
Peeler SA:
When assembling the Plate Peeler SA, align the arrow mark
on the Plate Peeler SA with the media contacting surface of
the Head Wire Cover as shown.
Also, when you stick a new Mark Label, align its arrow mark
with the media contacting surface of the Head Wire Cover.
(When assembling the Mechanism Unit, the media guide end
of the Head Wire Cover should be aligned with the chassis
plate of the Main PCB Block (as explained in 3-5-13
“Mechanism Unit”). Then, the media-path left-edges are
aligned on the basis of the Mark Label.
