We have an HP Color LaserJet 5550dn printer that is displaying colour problems.
I was called to it when output appeared to be lacking any magenta tones. Although the magenta cartridge appeared not to be empty, the user had replaced it.
When I print test pages, the full area of the pages have a pink tinge to them, where they should just be plain white. It now appears that the printer is printing too much magenta colour, casting it over the full area of the paper.
I have tried the available diagnostics and searched the HP knowledgebase but to no avail.
Has anyone experienced this before? Can anyone explain what is happening? Can anyone recommend a solution?
Many thanks. Colin.
