7 B Envelop print start
position shifts at top
edge.
<Supplement>
The top margin becomes
short. In the worst cases,
printing is performed
onto the platen. When printing is conducted to the
top edge of the printable area.
<Supplement>
Remarkable in the DL envelope. The paper feed roller slips on the paper at
paper feeding.
Note: Depending on the paper lots. Increase the top margin. -Print position shifts
-Smear on the backside
8 B Paper jam.
<Supplement>
The problem occurs just
after paper feeding,
without printing. The problem may occur in
continuous printing of special
paper (approx. 100 pages or
more).
<Supplement>
The problem may occur with the
SP101/PR101 series. Just after the LF roller starts feeding the
paper, the load at the LF motor increases,
causing the out-of-phase of the LF motor. 1. Press the RESUME
button to deliver the
paper.
2. Remove the jammed
paper from the paper
pick-up or output tray
side. -Paper jam error
-Paper cannot be fed
-Cannot print
9 B Smearing on printed
side. The paper curl is substantial.
<Supplement>
-The problem may occur with the
DL and COM#10 envelops.
-The problem may occur in the
address side of KH201 (after
continuous borderless printing to
the message side), in the high
temperature and high humidity
environment. The edge of paper rises due to the large
amount of curl, causing the print head to
rub against the printed surface of paper,
resulting in smearing. 1. Correct the paper curl.
2. Recommend the user
to conduct printing in the
print quality assurance
area. (In the i320, the
head-to-paper distance
cannot be changed.)
Note: In borderless
printing (to postcard,
L-size, 4X6), correct the
paper curl. -Smear on the printed side of
paper
-Cannot print properly
-Paper edge crease
