7.3.3 Pen Trace Troubleshooting

Procedure
Table 7-3 explains how to troubleshoot a pen trace problem.
Step
Check the ink cartridge for proper
1
installation.
Check that the chart agrees with the
2
actuation type and chart set up.
Check the pen alignment.
3
Look at printed circuit assembly (PCA) for
4
the pen to see if the red* LED is lit. This
LED is lit when the PCA failed a self-
diagnostic, or an out-of-range input has
been detected. (Flashing green LED is
OK, it indicates that the processor is
active.)
5 Check the sensor for the proper type and
its ability to function.
Replace the servo plate assembly.
6
7 Replace the printed circuit assembly for
the pen with the problem.
