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.
