Replace Transfer Roller Error Message Will Not Reset After Replac

I have a Dell 5100cn that was reading 'Replace Transfer Roller'. The machine would still print, albeit poorly. I replaced the Transfer Roller and the print was somewhat better but with the same error message. I issued the command to clean the magenta color (as I recall) and at the end of the cycle the machine still had the error 'Replace Transfer Roller' but now does not print at all.
Advice for troubleshooting this unit and resolving the issue is hard to find. The only solution that I have found resolves the issue by replacing the Machine Control Unit. This is a costly repair if it does not solve the problem.
What can I do to narrow the solution to a the correct part?

    I have reset the print count. The problem was resolved by cleaning the optical sensor that reads levels of the transfer roller waste tank. I used canned air to blow out any toner particles and the machine began to print again. But the print is poor. A test print of pur black shows a light area, maroon in color, on one side of the page and has two horizontal lines approximately 8 px high, also maroon in color. A print of a mostly black image show horrible maroon discoloration on one side of the print and smudges throughout. What's next?

    Although this post is ancient, I am glad I stumbled across it because you are absolutely correct. Once I popped the white tab over and pulled the transfer roller out, I shook the cartridge inside a garbage bag and it prints just as good as day one now! Thanks!

The transfer roller on this machine comes as an assembly consisting of a waste toner tank and a transfer roller. The message you are getting pops up when this tank is full, regardless of the transfer roller's useable life. There is a window on the back that when blocked by toner, cuts off an optical sensor to tell the machine that the waste toner is full. Just unclip the roller from the side, pop it out, and dump the toner out. Careful though, it's a messy job and you might want to wrap the assembly inside a trash bag while emptying it out.

I took the transfer roller out of the printer and subjected it to compressed air from my compressor in the garage. Do this outside, as you'll find that toner streams out all over the place. I was able to force air into the roller in certain areas that appeared to force the plastic out enough for the toner trapped in the transfer roller to escape. I think that, in my case, magenta toner got oversupplied and filled up the transfer roller, as that is what came out when I forced compressed air through it. I also blew out the inside of the printer to make sure any optical sensors were not covered with toner. Had to power the printer off and on after replacing the transfer roller to get rid of the error message.

Right now the printer seems to be working well.

Replace Transfer Roller

If the printer still says to replace transfer roller even after it's replaced, then remove transfer roller and manually turn the gears on the transfer roller a few times. It must get stuck or something. Then replace the transfer roller and it should work.

Replaced transfer roller and now the printer makes a ticking noise

What you are hearing is actually the transfer roller.

As the printer is moving paper thru the machine, the transfer roller is also moving.

There is a clear lucite/plastic window on the transfer roller unit.

There is a sensor that reads light through that window. when the transfer roller fills up with waste toner, the light no longer can pass through this window, and you get that "change transfer roller" message.

Prior to "filling up", that window is kept clean of dusty toner by a small plastic " flapper" that goes round and round, flapping that window clean.

That is the noise you hear. It is not going to harm your printer in any way, however, you just happened to get a noisy unit.

If this is a brand new, genuine Dell replacement part, I would contact Dell and have them send you another one, telling them that the new one is defective and excessively noisy.

If it is an after market, or refurbished replacement, you probably got it at a discount, and as I said, it will not hurt your printer, it is just going to be a little noisy

Buying and replacing just the transfer roller on a Dell 5110cn

Maybe if you call you can order just the transfer roller. You could try removing it and cleaning the ends (to provide better electrical contact). You could also try wiping the roller itself with a lint free dry cloth - but do so at you own risk and never touch the roller with your fingers!

Pop the lens cover off of the transfer roller, clean all the toner debris out of there and replace the lens, put clear tabe on it, and you are good as new!

010 397 Error Message on Dell 5100cn

The following steps are the troubleshooting steps that should be followed for error code 010 397.
First, the definition of the failure is <IOT Fuser Failure>, and means a Fuser Error is detected.

1) With power off, reseat the fuser by physically removing it from the printer, then reinstalling it and locking it in place. Turn the power back on. ( if the error is still present, proceed to step 2 ).

2) If reseating the fuser did not resolve the problem, Replace the fuser with a known good fuser.
( if problem is not resolved, proceed to step 3)

3) Replace the LVPS ( low voltage power supply ). ( if problem not resolved, proceed to step 4 ).

4) Replace the PWBA MCU ( printed wiring board assembly - machine control unit ).

END of troubleshooting.........

In most cases, the fuser itself is the problem. If you tried to reseat or replace the fuser while power was still on, the LVPS could have been damaged just as if there were an electrical storm.

Hopefully this helped.
