estudio 230 C970

[mrfuser]

Okay, new drum, blade, developer, fuser, etc.

Machine goes into a C970. Charge corona looks just fine, it is the sawtooth type of corona with a grid. Drum will go completely black with toner when try to run a copy so obviously something is wrong with charge, but what?

Ever seen this?

Thanks

Did you check transfer corona?
I had same problems when transfer corona wire got broken.

[mrfuser]

No broken wires. Would not this cause NO TONER on drum?

cut three turns off m/c spring. If so, need new spring. Happened a ton on e450 series, (along with multiple mods also)

[mrfuser]

okay, but spring is pulling the sawtooth corona, not a standard wire. Would this make a difference? Also when we go into service mode and do an 03-252 to turn on the corona it immediately pops the C970 code. Sounds like a buzzing from inside, must be a short somewhere in there, just having a lot of fun trying to find out what it is arcing on!

Any tips are appreciated!

yes, happened to me on the 230 series a few times. Also check on the machine where the m/c goes into, I have had that fall apart.

The connector at the rear of the machine was out of place. What a job to get to it! Sheesh, could Toshiba bury it any deeper?

I got this trouble few months ago.., Check the side cover if there is broken or parts from it.., the two important parts for this trouble C970 are rear main charge corona terminal if broken and the side cover can take this trouble.
