Paper Jams; Serial Interface Operation Precautions - Citizen CT-S851 II User Manual

4.8 Paper Jams

Take care to avoid obstruction of the paper outlet and paper jamming around the
outlet during printing.
If paper cannot get out of the printer, it can roll up on the platen inside the printer and
cause an error.
If the paper wraps around the platen, open the paper cover and carefully pull the
paper out.
4.9 Serial Interface Operation Precauti ons
While using the serial interface, certain printing conditions can cause white stripes in
printouts and feed failure. To avoid these problems, change memory switch settings
as described below.
1. Change MSW7-1 (serial baud rate) to a faster baud rate setting.
2. Change MSW10-2 (print speed) to a lower level.
CAUTION
Depending on the serial interface transmission speed, ambient temperature, print data duty,
and other factors, changing the above settings may not eliminate the problems.
