TAG 130: Diskette/Disk Drive Malfunction
Error Code: 130, 131, 133, 134, 450, 451, 572-576, 586
Symptoms: Test prints do not run
Possible Defects: Diskette
Disk drive assembly
Connectors or wiring

Electrical problems on wires J/P31 to J/P79 and J/P31 to ground may cause diskette and
disk drive malfunctions. If this TAG does not correct the problem, suspect an intermittent
failure from the disk drive to the IGS board cable and replace the cable from J/P31 to J/
P79 to J/P30.
The causes of error code 574 or 576 may alter the information on the diskette. You may
have to replace the diskette with another known to be good.
