TASKalfa 2554ci Color defects

[axtolf]

I have a customer with a used TASKalfa 2554ci
(40000 pages), the printer just arrived. We realized there is a problem with colors, yellow and magenta are not printer well. We tried all the maintenance operations possible, included several drum cleaning. We also tried to change the cartridges, but the defect remains.
About the defect please see the attached image (the black lines were added to hide a couple of personal information). IMG-20240203-WA0003.jpg
I tried with the color color registration correction and the chart seems to partially missing the yellow and the magenta:

That's definitely yellow and magenta developer issues. It sounds like you're an enduser. You'll want to have a tech install new yellow & magenta developing units, and then perform the color calibration again. Make sure that you're using genuine Kyocera toner (aftermarket toner can cause this). =^..^=

Thank you very much for the answers. I'm quite surprise we already need to change DV units, I think they are designed to last more than 40.000 copies but most probably who owned the printer before did something wrong (like using not original toner as you already suggested). I was hoping it was something that can be fixed before replacing parts, but thats it...
Yes not exactly enduser, It professional but not working on printers.

One last question, based on your experience, is it possible that this is due to damage during the movement of the printer from one place to another ? Only for my curiosity...

Do you know if it sat in storage for an extended period before it was purchased?
Was it climate controlled storage?

It was in another office, not being used for some months as I know.

Developer needs to be stirred regularly to maintain it's integrity. Based on your counts (90% K, 10% color), it could have very well been put away months ago with this defect. The more that you use color, the more yield that you'll get from the components.

Equally likely the machine could have sat unused for a long time. Either one could cause the same effect. =^..^=

Thank you very much

If you're going to spend money anyway, you've got nothing to lose by letting the machine sit idle while turned on for a while and then print out a couple hundred of color pages to see if it recovers.
