Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
I would rather not recommend anything, until I can be sure of what problem the printed pages show.
Can you post a scan of a typical affected page, please?
Also - Does a photocopy (if your model of LaserJet does photocopying) show the same effect?
I am not affiliated with HP.
I had an internet access outage - please pardon the delay.
If you should wish to continue, a scan of the affected document page, can be attached to your reply using the paperclip icon.
Or send it to***@******.***
and they will pass it to me.
