Question about HP Photosmart 8450 InkJet Printer

1 Answer

My HP Photomart 8450 prints in black sporadically.

I have an hp Photosmart 8450 printer which I bought 2/7/05. Over the last two years the print on black has been deteriorating. At first it was just on 'fast/economical' but now on 'general'. It is rather random, two whole lines out of ten or the first line out of 16, but it is by line. I have gone through the processes listed in the book: cleaning and aligning. The print will improve for a couple of prints and then go back to the problem. This happens daily. I paid a lot for this machine and am very frustrated.Joan

Normal 0 Driver could be corrupt.
Normal 0 Disconnect the printer or at least be sure it is turned off. I'd do both and reinstall the CD software program that came with the printer. When the software program asks you to connect the printer to the USB port, do so and it should again work properly.
Hope this helps. Bud

This is a long shot but have you recently installed new ink? I have seen a lot of people mentioning a similar problem since the newer ink cartridges.
If yes, then print an alignment page and go through the instructions, it shouldnt (fingers crossed) happen again after that. Let me know how you get on :)
