Unable to print

[ConnieNi]

Hello,  my 2018 HP Envy 4520  Printer displays the message:  "Incompatible Cartridges.  The indicated cartridges are not intended for use in this printer."  However, these cartridges were sent  to me  from  the HP Instant Ink program.     Can someone please advise?   Thank you.

Welcome to the HP support community

I understand that you are getting a cartridge error, I a glad to assist you.

Reset the printer

• Reset the printer to recover from printer errors or failures.
• If your printer has a rechargeable battery, remove it.
• With the printer turned on, disconnect the power cord from the printer.
• Unplug the power cord from the power source.
• Wait 60 seconds.
• Reconnect the power cord to a wall outlet and to the printer.
• NOTE:HP recommends plugging the printer directly into a wall outlet.
• Turn on the printer to complete the reset.

Clean the ink cartridge and carriage electrical contacts

• Remove any debris or buildup from the contacts on the cartridges and in the carriage.
• Open the door or lid to the cartridge access area. Wait until the carriage stops moving before continuing.
• Remove the cartridge indicated in the error message from the carriage.
• Carriages with cartridge latches: Open the latch, and then pull the cartridge up and out of the slot.
• 
• Carriages without cartridge latches: Gently press down on the cartridge to release it, and then pull it out of the slot.
• 
• Holding the cartridge by the sides, remove any protective tape that still might be on the contacts.
• CAUTION: Do not touch the ink nozzles or the copper-colored electrical strip. Touching or trying to remove these parts can result in clogs, ink failure, and bad electrical connections.
• 
• Lightly dampen a lint-free cloth with distilled water, and then wipe the copper-colored contacts on the cartridge.
• 
• Lightly dampen a lint-free cloth or swab with distilled water, and then clean the electrical contacts in the carriage.
• 
• Wait 10 minutes for the contacts to dry, and then reinsert the cartridge into its color-coded slot.
• Repeat these steps for the other cartridge if it was indicated in the error message.
• Close the door or lid to the cartridge access area.
