Resistors, Terminating
For parallel interface configurations, the printer is equipped with 470 ohm pull-
up terminating resistors and 1K ohm pull-down terminating resistors on the
controller board. These are suitable for most applications. (See Figure 38,
page 236.)
If the standard terminating resistor pack is not compatible with the interface
driver requirements of the host computer, other values of pull-up and pull-
down resistors may be required. 220 ohm pull-up and 330 ohm pull-down
alternate terminating resistors are provided with the printer. If you install the
220 ohm pull-up resistor, you must also install the 330 ohm pull-down resistor.
Possible terminating resistor combinations are shown below.
Removal
ATTENTION
To prevent electrostatic damage to electronic components, wear a
properly grounded static wrist strap when handling circuit boards, the
shuttle frame assembly, and any other electronic component.
1.
Prepare the printer for maintenance (page 152).
2.
Cabinet Model: Remove the paper guide assembly (page 229).
Pedestal Model: Remove the top cover assembly (page 204).
3.
Locate the terminating resistor packs. (See Figure 38, page 236.)
4.
Using a chip puller, remove the packs.
Installation
ATTENTION
To prevent electrostatic damage to electronic components, wear a
properly grounded static wrist strap when handling circuit boards, the
shuttle frame assembly, and any other electronic component.
1.
Using a chip installation tool, install the resistor packs in the correct
socket. (See Figure 38, page 236.)
2.
Cabinet Model: Install the paper guide assembly (page 229).
Pedestal Model: Install the top cover assembly (page 204).
3.
Return the printer to normal operation (page 153).
