Printer is in "single cartridge mode" - how to change this?

[Aardvark1]

Hi @betty341. 

Welcome to the HP Support Forums. I understand that your printer is stuck in single cartridge mode. I would like to help.

Normally the printer will exit single cartridge mode when it detects the second ink cartridge.  It seams that the printer is currently not detecting both ink cartridges. 

Try this: 

Remove the ink cartridges from the printer. 

With the printer turned on, disconnect the power cord from the rear of the printer.
Unplug the power cord from the wall outlet.
Wait at least 60 seconds.
Plug the power cord back into the wall outlet.

Reconnect the power cord to the rear of the printer.
Turn on the printer, if it does not automatically turn on.
The printer might go through a warm-up period. The printer lights might flash, and the carriage might move.
Wait until the warm-up period finishes and your printer is idle and silent before you proceed.

If you are still having a problem, try this document. HP Inkjet printers - Ink cartridge errors and HP OfficeJet Printers - 'Incompatible' or 'Defective Cartridge' message 

Let me know if those steps worked for you. If they did, that’s awesome! Give us some reinforcement by hitting the solution and kudos buttons, that’ll help us and others see that we’ve got the answers!

unfortunately this did not solve the problem.  When I check ink levels, both cartridges indicate more than 1/2 full.  But the alignment page is incomplete - only shows blue, red and gray.

The "solution" was to remove the black cartridge which was more than half full and had been working prior to replacing the color cartridge and REPLACE it with a new cartridge.  Is there any way to recoup that cartridge that still has ink in it?  

I also have questions about how to recoup several cartridges which now say "incompatible" on them.  They worked on an Envy printer which uses the same cartridges as the Officejet.   There is a lot of money involved in these cartridges.
