Fatal Error Code 17: PC Driver Error
This error occurs when the Mechanism Control ASIC detects that a
single phase of the Perforation Cutter (PC) Motor was energized for
longer than the allowed period of time. This indicates a malfunction of
either the PC motor, or ROM Board PC motor driver circuitry, or both.
Check the following in the order below, testing functionality at each
step. If either the PC motor or driver circuit on the ROM Board have
failed, always check both before installing the replacement part.
1. Check the PC motor connector on the Sensor Board. See
on page 140.
2. Check the PC motor, and the driver output signal on connector
CNSEN2 on the ROM Board. See
3. Replace the Perforation Cutter Unit, or
both.
Fatal Error Code 18: PC Error
This error is indicated when the reference position is not detected in a
perforation cutter operation.
Check the following in the order below. Do not replace the PC Unit until
the driver circuit on the ROM Board has been tested and you are sure it
is functioning properly.
1. Check the fuse on the +37 V line.
2. Check the ROM Board connectors CNSEN1 (signal input from the
reference position sensor), and CNSEN2 (drive signal output). See
Figure 4-10 on page 137.
3. If the driver circuit (ROM Board) tests OK, replace the PC Unit.
