DOES anyone know how to fix this code?Pcu's and dv's are not old.Thanks

[rsyarcia]

what is the model?

[Polarbear]

Please supply the model number of the machine that is causing you this hardship, as it could be caused by several things depending on machine model.

[Hemlock]

Addendum: Put the model number in the title - always.

This is what Goose's Guide suggests:

Drum/dev bias error - replace paper transfer unit

Drum/dev bias error - replace high voltage supply unit

Drum/dev bias error - replace drum unit(s)

[nmfaxman]

High voltage power: Drum/ development bias output error
An error signal is detected for 0.2 seconds when charging the drum or
development.
􀂃 High voltage leak
􀂃 Broken harness
􀂃 Defective drum unit or development unit
􀂃 Defective high voltage supply unit
491 D
1. Check or replace the harness.
2. Replace the drum unit or paper transfer unit.
3. Replace the high voltage supply unit.

Can't we just delete such time-waster topics if people aren't qualified enough to start threads with some kind of minimum informations we need in order to give support, like:

- model?
- what issue/symptome?
- is it permanent/sporadically?
- already performed measures?
- PM status of the machine (in case it might be relevant)

Maybe, after some public brainstorming, a mod can write a little guide and make it sticky somewhere so at least we don't need to teach pre-school basics and re-invent the wheel all the time. Maybe it's just me thinking that these insufficiant threads are a growing phenomenon.
