Owner`s manual

The new logic board supports both paper

sensors and has:

•

A selector switch that allows this board to be used

with both the mechanical and the optical paper

sensor (Figure 6, #1). If a mechanical paper sensor

is installed, the jumper should be on pins 1 and 2. If

an optical paper sensor is installed, the jumper

should be on pins 2 and 3. An extra connector

CN1

1, that is used for the optical paper sensor

(Figure 6, #2). Connector CN9 is used for the

mechanical paper sensor (Figure 6, #3).

• A new ROM version that supports both paper

sensors.

FIGURE 6

The old logic board only supports the mechanical

paper sensor unless it is modified. See the

Optical Sensor Kit Assembly procedure, which

follows.
