My HP Photosmart 5520e printer has started to print 2mm lighter (not white) horizontal lines every 1.5cms, particularly noticeable in blocks of colour; (e.g. lighter yellow in yellow block). I have used HP's Printer Doctor, aligned print heads & cleaned print heads using the printer's screen and a lap top using 'HP Printer Assistant' wired to the lap top (after each of which the print outs show the problem continuing), manually checked the HP original cartridges are clean, and the printer states that the cartridges have plenty of ink left. I have swapped cartridges with another printer which prints fine. Those also do not solve the problem in this printer. I have been on HP's help sites, all to no avail. The problem is less obvious when using the high quality print option, rather than normal quality. It is particularly noticeable in yellow, getting less pronounced as the base colours get darker through Magenta, Cyan and Black when running the Print Quality Diagnostic. The lines show when printing and when copying. I am not aware of any changes made to the printer. The only other recent changes were a first time connection from an Apple MacBook Pro although printing was fine for a few days afterwards. Prior to that the Printer had fed off a lap top with Windows 7. I am currently using another lap top with Windows 10. Since I am also running some print commands directly from the printer (e.g. cleaning including print reports) I doubt it is to do with the lap top set ups. The printer has a wired connection. Does anyone know of any other quick fix ideas short of perhaps changing print heads or more likely at the price the whole printer? Thank you and apologies for the long note.
