Paper Jams; Serial Interface Operation Precautions - Citizen Systems CT-S251 Benutzerhandbuch

4.6 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.

4.7 Serial Interface Operation Precautions

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.
