I am installing a new Envy 7855 and the printer does not recognize the cartridges.

Have already attempted a hard reset and it still does not recognize them

Welcome to HP Support community

I would like to help

Please try these steps

- Turn on the printer.
- Wait until the printer is idle and silent before you continue.
- Disconnect the USB cable from the rear of the printer. If your printer has a network or wireless connection, leave it connected.
- Remove the ink cartridges from the printer and clean the electrical contacts with a lint free cloth
- With the printer turned on, disconnect the power cord from the rear of the printer and from the wall outlet or power strip.
- Wait at least 60 seconds.
- Plug the power cord back into the wall outlet.
NOTE: HP recommends connecting the printer power cord directly to a 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.
- Reinsert the ink cartridges, and then close the ink cartridge access door.

1. Turn on the printer.

2. Load plain white paper in the input tray.

3. Open the ink cartridge access door.

   

4. Wait until the carriage is idle and silent before you continue.

5. Lightly press down on the ink cartridge to release it, and then pull the ink cartridge out of its slot.

   

6. Remove the new ink cartridge from its package. Be careful to only touch the black plastic on the ink cartridge.

   

7. Remove the plastic tape.

      CAUTION: Do not touch the copper-colored contacts or the ink nozzles. Do not replace the protective tape on the contacts. Handling these parts can result in clogs, ink failure, and bad electrical connections.

   

8. Hold the ink cartridge by its sides with the contacts toward the printer, insert the ink cartridge into its slot, and then gently push the ink cartridge until it snaps into place.

   NOTE: 

   Install the color ink cartridge on the left and the black ink cartridge on the right.

   

9. Repeat these steps to install the other ink cartridge, if necessary.

10. Close the ink cartridge access door.

Also ensure the printer has the latest firmware. Link: https://support.hp.com/in-en/document/c02919168
