I have a Color LaserJet 2605dn printer, and have just replaced the magenta cartridge - the previous one was leaking toner all over the printer.
The new cartridge does not print evenly. It is at full color in the centre of the page, gradually fading out to nearly nothing at both edges. I have printed several pages, and have given the cartridge a series or good shakes, to no avail. The other cartridges are over half full, and are printing perfectly.
Does this suggest a problem with the new cartridge? Or is there anything else I can try?

Was the leaking toner doing the same? If so that would indicate dirty optics which is common on this series. If not then the new toner may have issues.
Thanks for the reply.
Good thought. Yes, the leaky cartridge is also showing uneven print.
So if there may be dirty optics, where are they located and how do I clean them? It's only the magenta cartridge that has this problem.

Thank you for that comprehensive link. It seems to confirm my symptoms exactly.
As you say, it will be quite a job, but as the alternative is a new printer, I will go ahead and tackle it.

Followed the process with great care, and there was indeed much dust on some of the optics. But upon re-assembly, there is another problem - perhaps not all that surprising given the delicacy of the job.
I am now getting an error message "50-7 Fuser Error", which means "Fuser Open Error" according to my manual. The first time I turned it on, and printed a test page, the page partially printed then jammed. Once I cleared the jam, this fuser error appeared, and now I get it immediately following the "Ready" indication every time I turn on.
Is this error likely to be related to all the unplugging and plugging back of all the connections that were required during the cleaning process? I have been very careful, and have since repeated the disconnection and re-connection process, made sure no pins were bent or wires broken, and that all plugs were properly seated: it all looks good now. Which connector is likely to be the culprit?
Or is it possible that there is a genuine Fuser problem somewhere? If so, where do I look, how do I know what to look for, and is there any obvious remedy?

Thanks for the reply, and aploogies for the delay.
I am attaching as requested a picture of the error message in the 2-line LCD display - it doesn't come out very clear, as the contrast is low, but it says "50.7 Fuser Error. Turn off then on". My manual has errors 50.1, 50.2, 50.3, 50.7, 50.8, 50.9 listed, and the description for 50.7 is "Fuser Open Error" - see copy of manual entry.
I also attach a picture of the DC controller board, and I have double-checked that all of the connectors shown are fully seated. I don't see any unconnected wires. Now, when I removed the connectors to get at the optics, some were difficult to remove and I had to be very careful to avoid damaging the wires into them, but as far as I can tell they all seem OK (but hard to tell for sure).

I suspect that the issue might not be with connections to the DC formatter: this is the sequence after I completed the cleaning of the optics and re-assembly:
- Printer came up normally, and gave the "Ready" prompt.
- I printed a test page, which started to print, but the paper jammed - concertina-ed up against the upper rollers.
- Cleared the paper jam, and immediately got the Fuser Error message.
- Now I get the fuser error every time I power on, and the printer will not accept any print jobs or test pages. The fuser error is also reported in the printer web page accessible from the computer.
Since the printer did start up normally once after re-assembly, it suggests that the re-assembly was correct. So I would like to see whether the Fuser Error is a genuine fuser fault. So my question is: exactly what is the Fuser, where is it, and how can I test it for the "Open" condition that the fault code is reporting?
Any help would be appreciated.

The fuser is too complex to evaluate whether it is at fault, or whether the issue is on the logic board. I am not willing to replace the fuser with no certainty that it's the problem. Still got that Fuser Eror message and no printing.
So it looks like I will have to give up on this printer and replace it, but when I started this that was always a risk. That's life, I guess.
