Symptom

Soiling at back of sheet (Staple Finisher-D1/Booklet Finisher-D1)

[ Manual-related ]
Description
In a machine with Staple Finisher-D1 or Booklet Finisher-D, soiling at the back of the sheet [A] may occur
when shift mode or staple mode is used.
Cause
When shift mode or staple mode is used, paper alignment is performed in the Process Tray Assembly of
the Finisher. During paper alignment, the upper paper and the lower paper rub against each other at the
portion [E] sandwiched between the Stack Delivery Upper Roller [C] and the Stack Delivery Lower Roller
[D], and toner on the paper on the Stack Delivery Upper Roller side stick to the lower paper.
[Reference] This symptom occurs more frequently when paper having higher friction coefficient is used. It
is assumed that when a mixture of sheets of coated paper and sheets of plain paper is used, toner on the
plain paper stick to the coated paper, thereby soiling the back side of the paper.
Field Remedy

Service mode > SORTER > Option > SLD-BCK (Setting of bleed-thru prev mode)
Setting values:
