DRUM: Index not detected (error number 6013)

Applies to

VLF Platesetter
VLF Trendsetter

Description

Solutions

See Drum: Position Error - drum rotation blocked or PID gain settings wrong (6024).
See General VLF drum drive, encoder, and PLL troubleshooting

Notes

If none of these solutions fixes the problem, the cause could be bad encoder electronics casting
machining, excessive encoder disk face runout or a damaged disk (this is less likely).

Adhesive has been found on one encoder disk. It did not clean off with isopropanol and interfered with the indexing.
