[Error Code] Error Code F2-40 on Sharp MX 2700N

[rightbrained]

I recently rebuilt the black drum on my Sharp MX-2700N. The rebuild was for the green roller only - I did not get the blade. When I rebooted the machine, it worked fine - the issue I was having with back ghosting was gone. However, there was a streak running down the middle of the page.

I pulled the black drum out to discover a piece of the protective paper from the factory jammed in there. I pulled it out and was very happy that I had solved my problem.

However, when I rebooted, I received error code F2-40, which I take to understand is a black toner supply problem.

I cannot recall, but there is a possibility that I may have forgotten to turn the screw to the "U" shaped opening the last time I pulled the black drum.

Could this have caused the black drum to fall out of alignment some how?

Or is there another issue I need to look for?

Of course, I am extremely behind my printing schedule after waiting for the rebuild kit and a day lost doing the above described.

Remove the toner cart and run SIM 25-1. If the K value is below 25, you have too much toner in the DV unit; skyshots or DV change to remedy.
If the K value is above 231, you do not have enough toner in the DV unit; clogged toner feed pipe or bad toner cart.

Thank you for your insightful reply. I'm sure you know exactly what you're talking about. However, I don't. I'm a print shop owner trying to maintain my own equipment. Is there somewhere I can download a true service manual for this model so I know what you mean when you say to run certain tests? I have several manuals I've found online, but they don't offer service codes. I've picked up a few here and there on forum sites such as #*C* 14 to clear a service code, but otherwise, I am at a loss. I'm fairly tech savvy and know my way around my own particular copier model.

Otherwise, you could take a moment and explain running SIM 25-1. I understand that is asking a lot of your time and if you're busy, I will understand.

Thanks

25-1 is a service simulation you use #*C* but instead of 14 you use 25 then press either copy key, After this you press 1 and press either copy key. Then press execute. The TCD_K value is as mojorolla has described.

Thanks to Mojorolla and Sharphead for their assistance in this issue. Apparently the K toner running out right after I rebuilt the drum was a coincidence and had nothing to do with each other.

I would still like a list of service/technician codes and their applications for my model (Sharp MX-2700N) if anyone can help me.
