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.
