ERROR MESSAGE
PROBLEM
SOLUTION
Any floppy or hard drive error
message
May be a problem with the
diskette, the drive, the cable,
etc.
Refer to Appendix K.5 and
K.6 for drive-related
troubleshooting dialogues.
System Startup State 4, 12,
13, or 14.
The “I” (film wedge) and “J”
(glass wedge) motors or
associated assemblies are not
operating properly.
Print out the system log.
Normally, numerous other
error messages indicating
either the “I” or “J” wedge will
be seen. Determine which
wedge is causing the Startup
State error.
Check for any mechanical
rotation problems. Verify that
the wedge passes freely
through the edge detector.
Ensure that the film wedge is
not slipping off the brass hub
that it is mounted on.
Check for any scoring marks
on the wedge’s opposing
brass hub. If scoring marks
are present, the pin on either
wedge, aperture, or color
wheel hub may be too long,
causing them to be incorrectly
positioned.
Check the ease of rotation on
the opposing wedge hub.
Remove the aperture or color
wheel as required to clean the
shaft and bushing.
Verify the functionality of the
appropriate edge detector and
motor.
Check for proper alignment
along the entire projection
path.
