Changed item: Glitch corrections
1. We have corrected the problem of rare paper jams (APPD2_SMF) that occurred when
manually feeding the paper.
2. We have corrected the problems that caused the transport roller to stain the rear face of
the first page and at 25mm from the bottom of the second and following copies when
printing two or more copies of A3 or 11 x 17-size paper using the Saddle Stitch or 2-
point Staple mode in double-side print mode.
3. We have improved the SPOD_N jam and problem of misaligned edges of copies.
4. The magnification changeover of the scan speed has been changed as follows in order
to improve the blurring generated when executing scanning with 200% magnification
with the OC mode of the scanner unit.
5. We have corrected the problem that keeps the SPF motor running after all documents
have been discharged when continuously feeding mixed-size documents of special-size
paper from the SPF. (Small-sized paper such as sales vouchers and B4-size paper in
this case: a different length but the same width.)
