NOTE: The “Top Mylar” is not shown in the diagram above.
The bottom Mylar wears out in the location where it is in contact with the corner of the
middle Mylar, positioned immediately above. The bottom Mylar is squeezed between the
corner of the middle Mylar and the paper passing beneath, and this pressure and abrasion
damages and thins down the bottom Mylar.
Damage to the bottom Mylar is prominent when fed “Heavy” and “Large Sized” paper
stocks. Paper of “Weight 4” or heavier will tear away the bottom Mylar.
Required Action
Peel off and remove the bottom Mylar from the PTR entrance guide plate when making
new customer site installations by referring to the procedures described hereafter.
This rework will take approximately 10 minutes.
Please be noted that labor fee will not be compensated for this rework.

abrasion
Breakage
Friction from feeding and pressure from
the middle Mylar and paper causes to
abrade the bottom Mylar.
Thinned down areas and holes cause
to tear apart the bottom Mylar.
Continuous abrasion thins
down and eventually creates
holes on the bottom Mylar.
