MX-5141N Depleted Cyan Developer After Replacement

[Mike557]

Looking for a little help on our Sharp MX-5141N machine. We were overdue for color developer replacement, at the same time Cyan developer became depleted and started causing stripping on the prints. Replaced all CYM developer and performed recommended sims. Worked great for about 2000 pages, however the Cyan developer is now depleted again. Anything I should check or replace to find the root of the cyan developer depleting so quickly? Thanks for your help!

Unfortunately this is a known issue, Start by replacing the drum and charge and see if that helps, we had two 4141 machines doing this and this fixed one of them and the other we ended up replacing the MFP power board.

Hello, thanks for the info! So I could replace the MX-5141N OPC Drum Unit and is it correct that the main charge unit is built in or is that separate? Also, do you know if there is any way to get just the Cyan developer, or is only sold in complete kits? Having a hard time finding just Cyan developer!

Just replace the unit or rebuild with the charge kit and drum. the developer only comes in the three pak .

Thanks for the reply again! Okay great, I will give that a shot. Might just swap the whole thing out. I am the unofficial office printer and copy machine technician, along with my full time job... My theory is the color developer is all the same and some guy in finance at Sharp suggested they put a little of each color toner in it, so it is no longer interchangeable!

if you are an end user there are steps you need to go thru when you change the developer that a tech needs to do.

Yes I followed the service manual and confirmed the clearances and performed the recommended sims. I assume that is what you are referring to?

The toner is in there because it is the perfect amount,when the developer and toner mix in the augers they create a electricity and when you run the sims with the new developer it is setting the toner sensor to that perfect amount of toner and then the machine maintains that level as you make copies. I have not done it but others will use whatever color developer they have. The copies will be off color for a while until the toner is used and the correct toner is cycled in. It will gradually go back to normal.

Also make sure to replace the waste toner container!!! What happens is that the waste toner is not replaced causing the foam seals on it to get smashed down, and deformed. This results in waste toner/developer getting "blown" back into the PCU, hence you get a build up on the charge grid. This causes the developer to be sucked out of the developer unit (the charge grid arcs to the drum). This is why you MUST replace developer, PCU (or rebuild) and waste toner container together when this happens. If you just do one or two of these 3 things, you are not fully rectifying the whole problem.

Thanks for the information. Was planning on replacing the container as well and have one on order. Will all be here Monday so I will know if that fixes the issue. Thank you all for the help!

If you have a yellow developer you can use it. Put it in the DV unit and run 25-2 as normal. Then run sky shots until the yellow toner that is in the developer is replaced with cyan. Then go back in and run your normal calibration procedure. Takes a bit but saves lots of cash.

Yes, I actually have an extra yellow developer and was planning on trying this before breaking down and buying a whole set. Thanks for confirming it should work!

You are welcome. I have done this with the other colors but it takes longer.

Our company stayed away from this series because of this issue,however, it was not as bad on the 41 series for us, but the 51 series, forget about it. Our company placed most of the clients in other series because of this issue, Sharp made some attempts to try to resolve it, updated drum units, waste toner containers, etc, but they still suck toner and developer if not maintained regularly. If we have a client that is still has a 5140/5141 we just do courtesy calls if we are in the area, to prevent this from happening, even though we have provided all of Sharp's updates. Again make sure you are following proper procedure in service manual ( 1-C), no toner installed, door open, updated parts, current firmware, etc.

Replaced the whole drum unit, waste bin and used the yellow developer we had on hand. Took about 75 pages front and back to get the yellow to green. Good enough to start printing our user manuals again as it continues to transition to blue. Much cheaper than buying a whole developer set. Thanks for your help. Ill let you know in a week or two if this fixed the depletion issue. Thanks again!
