Chapter 5 Terminating Resistor Configurations

Terminating Resistor Configurations

The factory equips the printer with several resistors that are used for parallel interface configurations and are suitable for most applications. These 470 ohm pull-up and 1K ohm pull-down terminating resistors are located at RP1 and RP2, shown in Figure 45.

If the values of these terminating resistors are not compatible with the particular interface driver requirements of your host computer, you may need to install resistors with different pull-up and pull-down values.

RP1 Default: 470 ohm

Alt 1: 220 ohm

Alt 2: 1K ohm

RP2 Default: 1K ohm

Alt 1: 330 ohm

Alt 2: none
