Re: HP Photosmart 5520 - HP update via wifi has caused blank printing issue

, Welcome to the HP Support Community!

Apologies for the inconvenience caused. Let us try these steps to resolve this issue:

Reset the printer

1. With the printer turned on, disconnect the power cord from the rear of the printer.
2. Wait at least 60 seconds.
3. Reconnect the power cord to the rear of the printer.
4. Turn ON the printer, if it does not automatically turn on.
5. Wait until the printer is idle and silent before you proceed.

Note: HP recommends connecting the printer directly to a wall outlet rather than a surge protector or a power strip.

Clean the printhead

1. From the control panel home screen, touch the Settings icon , and then touch Tools.

2. Touch the Down Arrow , and then touch Clean Printhead. The printer cleans the printheads, and then prints a test page.

3. If the print quality on the test page is unsatisfactory, perform a secondary cleaning of the printhead.

   If the printhead is badly clogged, it might require another cleaning cycle. If so, wait 30 minutes after the last cleaning stage to start the first stage of the cleaning process over again.

Also, perform step 9 mentioned in this document.

Try printing.

Let me know how this goes.
