Hello HP users,
Can anyone tell me why my DESKJET 3720 is printing with a banding fault please? Black and white prints look like a zebra crossing and colour prints look like the black is not pricing at all. Ink levels are fine and I've tried cleaning the heads.
Thank you in advance.

@DAVEtheTOG, Welcome to HP Support Community!
Are you able to make photocopies on the printer without any PQ issues?
What is the paper type and size used on the printer?
You can try updating the printer firmware. HP regularly releases new printer firmware versions with product enhancements or issue fixes. Depending on your printer, apps on the printer control panel might also receive updates. Update firmware and apps on a regular basis to make sure you are getting the most out of your printer. Refer to this link for help.
Keep me posted for further assistance.
