Scan and Copy All Black

[CLatt]

My ENVY 7855 will print fine, but every scan and copy comes out a full black sheet. All HP suggested fixes have done nothing.

Hi@CLatt, 

Welcome to the HP Support Community! I'd like to help!

I see you are experiencing issues with the HP ENVY Photo 7855 All-In-One Printer scan and copy is not working correctly.  

I have a few recommendations 

• Fix printing and scanning problems with HP Print and Scan Doctor, a free tool for Windows.
• If your printer is failing to copy and there is no response at all from your HP Envy when you attempt to run the copy, this generally indicates a hardware failure with the scanning/copying assembly built into your printer. Two things generally cause this failure: a power issue, or a programming issue.
• There are numerous possible causes for a printer that's randomly producing blanks. The most common ones are empty ink cartridges, improper cartridge installation, and congested nozzles. Driver and software issues can sometimes cause this problem as well.

Hope this helps! Keep me posted.

I tried the print and scan doctor and it didn’t find any issues.

And the machine does actually respond when a copy is made. It doesn’t produce a blank page but instead a fully black printed sheet of paper. As if the machine can’t read the page it’s copying and thinks it’s a black sheet of paper. But the lighted bar does move across the glass when attempting to copy.
