I have Color LaserJet Pro MFP M277dw and I'm getting blue dots printing on every page - spaced 1 inch or so apart down center of page. Any help or guidance on this?

Hi,
First try running Cleaning Mode and see if that may help, to do so go to Setup > Service and then select Clean Mode / Clean Page.
Next select Setup > Reports and select Supplies Status Report, then evaluate the printed report.
If you see any defects on this report then please scan the printed report and add it to your post to get a better idea of any possible cause.
If the page is clear try pritning from your computer and check if the clean page may helped.

Hi SFPineSt,
Yes, replacing the cyan toner will eliminate the issue.
Consider buying a full set of toners since your other toners are very low. Thus, you will get a better price rather than buying them seperately.
I hope this will help you,
Cheers!

Hello all. I'm experiencing the same issue. Blue dots down the right side of the page. I've changed the cyan cartridge twice with original HP cartridges. I've run the cleaning function twice and have blown out the inside with compressed air. Still, the issue persists. Are there any other things I can try? The model is m477fnw. Thank you for your help!

I too have an HP Printer MFP M477fdn exhibiting the same blue dots. I have run the cleaning solution and the dots persist (see attached scan of the supplies run after the cleaning).
Can you provide a solution other than replacing the Cyan Cartridge as still have 1000 copies left in this cartridge and they are expensive to replace. (unless HP is willing to send a free replacement?).
