Constant code during the warm up process. The HV/2, separation blocks, transfer rollers, separation plate and PRCB has been replaced. I checked for arcing no visible signs or smell of arcing.The machine only has 500K on it. This one is kicking my butt!

This is what the manual says:
When the second transfer was
ON, second transfer abnormality
detection signal was continuously
detected for the specified
time.
High voltage unit/2 (HV/2)
Second transfer roller

Any ideas?

Is the machine earthed?

Is that that little brass/copper earth connection on the transfer roller in good condition?

Also check on the secondary Tx roller that the hole on the shaft is toward the back of the machine.....

Yes its clean and in good condition.

The problem was resolved today, I replace the HV/2 again!
According to tech support another guy had to replace the HV/2 twice also.

One done, one million to go!

Good info.

Sometimes we need to remind ourselves that even brand new parts can have defects...even if it is counter-intuitive

indeed...... some of us have learnt the hard way.
