Termination Resistors

For parallel interface configurations, the printer is equipped with 470/1K ohm pullup/pulldown terminating resistors located on the printer motherboard.

Generally, these terminating resistors are suitable for most applications. If, however, the standard terminating resistor pack is not compatible with the particular interface driver requirements of your host computer, other values or combinations of pullup/pulldown resistors may be necessary.

If you are experiencing communication problems between the printer and host; such as double characters, incorrect characters, or loss of data, the cause may be the value of the termination resistors on the motherboard. Contact your authorized service representative for instructions on replacing the termination resistors.
