Blurred printing unless word document?

[leothetiler]

I have an HP F4580 and recently changed an ink cartridge. I did all the normal bits and bobs like the alignment, but whatever I do the printing is blurred. (they are official HP cartridges)

It seems to be both the inks that are blurred, and I only replaced the colour. Beforehand everything was fine.

I have since printed a word document and it was perfect, so I am now a bit stuck as to what the problem is. Any ideas please?

Disconnect printer from computer. Open control panel and select printers. Delete the printer. Now select File>Server Properties>Drivers. Remove the existing drivers. Reboot. Download fresh drivers from HP website (try and stick with PCL5e drivers if possible). Extract drivers to folder on hard drive. Connect printer back to PC, when it asks for drivers point it at the location of the extracted drivers. Test print

Thanks for the advice, I did everyting you said. Got my hopes up when I printed the test page but just the same. Any other ideas, I am at a loss as word documents print fine!
