How to clean HP CP2025 printer?

[buttonsrtoys]

I'm getting blue and yellow splotches on my pages. I opened my printer (CP2025) and saw lots of toner deposits, likely because I've been using cheap clone cartridges (learned my lesson!). The prints are still crisp and line-free, I'm just getting the random blotches.

Is this something a cleaning would solve? I so, how do I do it? I tried removing the cartridges and blowing compressed air through, but it seemed to make the problem worse. 😕

BTW, I should've mention that I did a clean thru the system menus and it helped a little, but the blotches are still pretty bad (sometimes dozens per page, about the size of this letter oh: "o", in random places). I'm thinking I need to clean some parts or maybe replace something?

Bad toner cartridges that should be replaced.

Empty the waste toner first if you can maybe it can be cured otherwise they have to be replaced.

Thanks @East2100! That solved my problem!! I took the two end caps of the yellow cartridge and the waste container was overflowing. I dumped it out and cleaned it with some air. The rest of the cartridge looked good to my untrained eye, so I put it back together and now it's printing beautifully again. I can't believe it. Was simple to do and now I have my printer back again. I'm indebted.
