C970 is a main charge leak problem.try removing a loop from the charge wire spring or putting a damper on the charge wire.Also would'nt hurt to check the end blocks

Re: c970

the key to most 970 codes is the vibration of the main chrge wire. The newest wire springs are heavier and pull the wire tighter. I've had really good success with them. I have also cut a couple loops off the original spring with good success as well.

C970 can also be T/S corona wires. We starting stringing our own with Katun wire, and have not had a problem since.

Re: c970

AS stated C970 can be Transfer /Sep corona or Main Charge, must say I've never noticed one with vibrating wires, though I can quite believe it. In my experience the most common issue after the old foreign object in the corona assembly trick, or broken component is arcing of the corona end blocks. I keep clear nail varnish in my tool bag, pull the whole unit apart and varnish the end blocks where they come into contact with the tray. Lasts for years, if necessary.

Re: c970

The calls for 970 code have gone way done since I started stringing the wires. It took some practice but it is worth it. I have also used white out on the end blocks.

Re: c970

I do encounter C970 due to main charger wire dirty... After cleaned, it can work nicely... But i found that some machine the wire get dirty easily... even after changed whole main charger unit, it will happen again...
