Originally the machine had grinding coming from the Black developer unit and it was packed with toner. I removed all developer and replaced with new then I had CE40 and I ordered and replaced the black developer unit assembly (NEW) installed and ran 05 - 2404 which it set up fine and then printed 15 pages. I shut the machine down and powered up and it came back up with error C380. What can it be? Was I supposed to run something else within setup for a new developer unit assembly? Thank you in advance for any help.

I don't know how important it is, but I always clear the appropriate counters before running developer stir and calibration. You also have color calibration to do.
In my experience C380 codes are usually caused by seized or seizing developer bearings, or stripped developing unit gears (as a result of that developer leaking). On this series of machines it is common for the air duct under the mag roller to fill up with developer. As part of your developer cleanout, you should have removed the bottom shield and vacuumed all the developer out of the air duct, and removed and wiped the surface of the toner sensor. If you are careful, you may be able to recover this situation by carefully tipping the developing unit onto it's back, cleaning the duct and toner sensor, close it back up, and pour any spilled developer back into the developing unit. Re-run the developer stir.
You might look at the primary charge grids also. On older Toshibas, if the grid comes loose and lays against the drum, You'll get images that immediately de-tone the developer (yes, even new developer). =^..^=If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

Thanks for your reply Blackcat, after the attempt first to change the developer from the OLD unit I then replaced the whole developer unit and setup using 05-2404, this is when I now get a hard fail C380 after the machine boots up. It did work for 15 prints in black at first, then I got the error. C380 constant now.Comment

Could it be the wrong part number developing unit? That doesn't discount an issue with the charge grid either. It should have been 6LJ54251C00 DEV-UNIT-H210-HLK, and there are three previous changes. They are not the came as color developing units, but if someone were to swap around the front pieces that interlock with the frame, it works.
I've had a few developing motors go bad on Masherbrum Series, but never on Weisshorn High. Does the developing roller turn manually? Does the motor attempt to turn? Those are all pulse motors, so you can put a fingertip on the motor counterweight and rotate the drive to see if it's too difficult or too easy to turn. I don't remember how hard it is to detach that motor, but that's another test you can do. Remove the motor, leave the wires connected, and power up to see it it tries to turn. Do all the door interlocks close? If the last thing the machine saw was C380, that's all you're going to see until all the door interlocks close. The manual lists Logic Board, but I'll rate that unlikely, unless of course your new developing unit had a dead short and damaged the logic board. The manual also lists a primary transfer belt unit failure. I can't see how that would be the cause either.
Try some things, and I'll think on it.If you'd like a serious answer to your request:

Check 05-2405 sub code 3 (the adjustment value for the K ATS), if it is less than 100 or more than 140 then the auto adjustment failed and the reading from the ATS is out of spec.
There are three possibilities, the mixing motor for the developer is not stirring properly (or the rubber wiper on the auger is missing/damaged, I have had this on a new developer before), there may be a high voltage leakage from the main charge assembly (charge grid, needle electrode, or a dirty/damaged cleaning rod), or it could actually be a faulty logic board.No, I will not send you Manuals, Software or your own little repair Genie to fix all your problems for you.

BTW I was not able to get back into 05 service mode ever since the C380 error?? I went back and removed the transfer belt assembly and all developer units and drums and cleaned the inner cavity of the machine. The machine warms up until "Ready" but won't print anything (Print total counter) and is stuck on the counter screen, no sound or reaction, when I try to copy nothing happens. The green start button is not lit green also. No error messages at all. Ready still shows up on the upper left corner of touch screen like all is normal, hmm? Also I still Can Not get into 05 mode but strangely I can get into 6S or 08 mode fine.
When I did setup the new developer unit I had 143v for the end reading.
I'm going back today to look again at the drum primary charge grids and also the logic PCB connections. The place this machine is in is filthy office in a manufacturing machine shop facility. Dog hair and so on. No one cleans in this place. Lol

Dirty manufacture places can be challenging.
I had one of these near a door that was almost always open to the plant, and they used a lot of welding equipment. Had to routinely remove the HV board and everything from there to the any of the HV connections and scrub them clean from time to time or the machine coded with various HV, toner density..etc.. codes as we all as just eating developer all the time. Also had lots of plastic deterioration around anything dealing with the HV like the corona units...Comment
