This is how to fix it. Please comment if I have helped you.
One of my client’s printers is a bit faulty and the HP repair centre couldn’t repair it. So I am going to take it upon myself to follow instructions from another blog on how to clean the laser lenses… updates will follow….
Here is the first update: Found the original blog, and an HP support forum both mentioning the same issue.
The issue is the MAGENTA colour printing faded colours.

I put in double links because sometimes the thumbnails don’t generate…
UPDATE:
I opened up the machine I had and fixed the issue. A little bit of dust on the lens and mirror was the culprit.
On the Reeves link, it took the guy quite a while, I managed to get it all done in under two hours. Also, you don’t necessarily need to take off the side panels – I did do it, but one could probably get away without taking them off.
Marking of the cables is important, I just used a fine tipped permanent market to colour the cable corresponding to the positioning. I counted positions 1 to 6, and then made the mark on the relevant cable.
I added the quote from HP’s official repair place. The quote is higher than the price of a new printer. And it was for something that isn’t even broken!
