Error Message:

DRUM: Hall velocity error - more than 20 percent during drum init.

Applies to:

• All

Service Information:

This error is reported if the drum velocity as read by the encoder differs by more than 20% from the targeted drum init velocity, i.e. gross velocity error. This may be caused by setting drum hppr incorrectly. Also loose drive belt, loose pulley, damaged motor ( try "drum spin 60 c" ), grossly out of calibration drum amp (do "drum cal" and save it), faulty drum amp control/data cable.

Operator Action:

Resume and report to Creo Response center. Also note velocity error message on diagnostic monitor if possible.

Cause:

• drum hppr set incorrectly
• Loose pulley
• Damaged motor
• Grossly out of calibration drum amp.
• Faulty drum amp control/data cable.
• Bad encoder
