Envy 4520 has ink but won't print

[dlanderson]

Both colour and black ink cartridges are 75% full. I have run diagnostics, cleaned printer heads etc. It goes through the motions of printing but the pages come out blank. Any ideas?

@dlanderson,

Thank you for posting your query on HP Support Community,

Are you using genuine HP Ink cartridges or refilled ink cartridges.

Have you tried manually cleaning the area near the ink nozzles.

Let's these steps here: 

Perform a Hard reset on the printer and make sure that the printer is connected directly to the wall outlet and not to the surge protector.

Remove all the ink cartridges and then try to perform a hard reset on the printer.

With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.

Remove USB cable, if present.

Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.

Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord and then plug back the power cord to the printer.

Turn on the printer and wait till warm-up period finishes and the printer is idle.

Now insert the ink cartridges and then try to print a test page and check if it works.

Let’s first try and make a “photocopy” to determine whether the issue is with the printer or not. Place a document on the scanner glass and choose “Copy” option. If the printer is making a good copy, then the printer hardware is fine.

If the copy comes out bad then I would suggest you follow these steps from this support document for - HP Printers - Black or Color Ink Not Printing, Other Print Quality Issues
