4.7 Operating Precautions for Serial Interface

White stripes may appear in the printout or the paper may not feed, depending
on the printing conditions, when using a serial interface. To prevent this, change
the memory switch settings shown as below.
1. Increase the transmission speed of the MSW7-1 (serial port).
2. Lower the MSW10-2 (print speed) level.
CAUTION
The transmission speed of the serial interface, ambient temperature, print data duty,
and other printing conditions may cause these problems even after doing the above
settings.
