Product: HP OfficeJet Pro 7740 Wide Format All-in-One Printer
Operating System: Microsoft Windows 11

Officejet 7740 ... first page prints beautifully, regular letter size.  After that, every page has a black vertical down the left hand side.  I've ran the Print and Scan Doctor, I use only HP cartridges and paper, I've run the realign and other 'maintenance' tips.  I've unplugged it to clear anything 'stuck' in its little memory banks to no avail.  Suggestions?  I have 6 days until my warranty expires so I need to resolve before then.  Lol  I did have a few days that a bunch of odd letters and numbers came up, printer would shut off and then come back on with no problems.  Not sure if that was a sign of something coming.  Did not write the screen items down ... happened twice.  I want to say they were different each time, but I could be wrong.
