C2790 - 3551ci

Re: C2790 - 3551ci

Who'd have thought?

Could you have missed a connector to the LSU cleaner motor? =^..^=

I never removed a connector from the LSU unit. I only removed the metal cover to get to the slit glass to clean. I need to double check that nothing came loose when I was cleaning it.

It appears there's a broken pin on the transfer belt connecter but it's really hard to see.

As for pins, try to make a good picture of connector and zoom it to see better.

Re: C2790 - 3551ci

If I did drag it out it wasn't on purpose. I read the manual from the beginning but it was hard to tell if the skew motor was part of the transfer unit or on the rear from. I figured it was on the transfer unit which is why I replaced the transfer belt first. Again, my apologies for the confusion.

FYI you don’t need to disconnect this when just pulling out the transfer unit to access the drums/Devs.
You can just pull it out slightly.

It's been a nightmare and it's still not fixed.


-I found a bent pin on the belt connecter. I replaced the connecter with no success.
- Replaced wiring harness from that connector to the control board with no success.
- Tried multiple transfer belt units with no success.
- Replaced control pwb with no success.
-replaced entire laser unit with no success. (I did that after reading the tech bulletin posted in this thread.)

Surely this is the issue "It appears there's a broken pin on the transfer belt connecter but it's really hard to see."

Yes, I pulled the connector and there was indeed a broken pin. Actually it was smooshed down. Anyway, I pulled a connector from a parts machine and replaced it. Still getting the same code.

Re: C2790 - 3551ci

did you check the machine side connector for the transfer belt. Its not easy to see a bent pin on that connector.
use a loop and a flash light

Surely this bent pin is the cause of your error??????

No, it did not fix my problem. Still getting the same code. When I saw the bent pin, I felt sure this was the problem. But it did not fix it.


PS - I think I bent the pin after I got the error code in the process of swapping transfer units.

Re: C2790 - 3551ci

Here's my latest problem on this damn machine. I tried updating the firmware after replacing the latest Control PWB and I'm getting the following error":


IH Error 0801

Any ideas?

Are you sure this error code is correct?

If it happened after you replaced the control board sounds like you have left a connector off or bent another pin.

Yes, the error code is correct. I'll double check for a connector that is unplugged or a bent bin. Thanks for your help.
