Hi @Yeltneb81,

Welcome to The HP Support Community.  

Thank you for posting your query, I will be glad to help you.

I understand your HP ENVY 4520 only prints the top half of the page and your serial number is being rejected, 

here are a few steps you can try to address both issues:

For the Printing Issue:

Check Print Settings:

• Ensure that the print settings are configured correctly in your printer software. Look for options like "Fit to Page" or "Shrink to Fit" that might affect the print area.

Update Printer Firmware: Update the firmware on an HP printer

• Check if there are any available firmware updates for your printer. Updating the firmware can sometimes resolve printing issues.

Clean the Printheads:

• Perform a printhead cleaning cycle from the printer’s maintenance menu. Sometimes, clogged nozzles can cause incomplete prints.

Check Ink Levels:

• Ensure that all ink cartridges have sufficient ink and are properly installed.

Perform a Printer Reset:

• Try resetting the printer to its factory settings. This can sometimes resolve issues with print quality.

For the Serial Number Issue:

Verify Serial Number:

• Double-check that you are entering the serial number correctly. Ensure there are no extra spaces or typos.

Check for Regional Differences: Refer to this document for steps to find the product details.

• Sometimes, serial numbers are region-specific. Make sure you are entering the serial number on the correct regional HP support site.
