Explanation
Purpose of the Bottom Mylar
Paper particles (coating material) accumulate on the edges of the middle and bottom
Mylars when coated thick paper stocks are fed. The bottom Mylar was attached to cover
the edges of the top and middle Mylars, to prevent the piled up coating materials from
scraping off the coated layer at the entrance of the PTR nip, causing the image quality
issue known as "white streaks". However, due to the paper jams caused by this bottom
Mylar, this Mylar was eliminated.
Feed performance / Image quality when feeding without the bottom Mylar
No particular problems were observed in the test conducted with the bottom Mylar peeled
off from the PTR entrance guide plate. However, if removing the bottom Mylar results in
image quality problems (white streaks), please contact your service supervisor, and
procure a modified PTR entrance guide plate, which will be supplied upon request.
RCL is currently reviewing whether this modified PTR entrance guide plate will be stocked
at each regional SPC.
Modification / Actions Required in the Field
While the PTR entrance guide plate is planned for a modification, RCL requests you to
peel off the bottom Mylar from the guide plate for machines having already been installed
in the field. RCL is now investigating the serial numbers of the affected units, which will be
announced in the revised version of this bulletin. Until then, we sincerely apologize for the
inconveniences caused by the extra work, but would appreciate your cooperation in
peeling off the Mylar by checking the ITB unit for each unit.
