Hi @al814,

Welcome to The HP Support Community.  

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

I understand you are facing an issue with your HP ENVY Photo 7155 printer, where the cartridges are not communicating correctly with the printer after cleaning the surfaces with alcohol. This type of problem may arise due to contact point issues or cartridge alignment problems. 

Here's how you can try to resolve it:
 

Steps to Troubleshoot Cartridge Communication Errors:

Turn Off and On the Printer:
Start by turning off your printer, unplugging it from the power source for a few minutes, and then powering it back on. This can reset the connection between the cartridges and the printer.

Check the Cartridges:

• Remove the cartridges and inspect them carefully. Ensure no residual alcohol or debris is left on the copper contacts.
• Ensure they are dry before reinstallation.
• Gently wipe the copper contacts again using a clean, lint-free cloth slightly dampened with water (not alcohol this time), as alcohol might leave behind a residue or affect the sensors.

Inspect Cartridge Slots:

• Look inside the printer where the cartridges are installed. Use a dry, lint-free cloth to gently clean the cartridge slots.
• Avoid using excessive force or liquids to clean inside the printer.

Reinstall the Cartridges:

• Reinstall the ink cartridges one by one, ensuring they are securely placed in the correct slots (black or tri-color).
• Listen for a click to confirm they are properly seated.

Check for Firmware Updates: Update the firmware on an HP printer

• Make sure your printer's firmware is up to date. Sometimes communication errors are caused by outdated firmware.

Reset the Printer:

• Perform a printer reset to clear any error states. This can usually be done via the control panel or settings menu, or consult the user manual for specific reset instructions.

Replace the Cartridges (If Needed):

• If the issue persists, try replacing the cartridges with new, genuine HP cartridges. Sometimes communication errors are related to damaged or incompatible cartridges.

Additional Notes:

• Avoid using alcohol on electronic contacts in the future, as it can sometimes damage sensitive surfaces or leave a film that interferes with electrical signals.
• If your printer continues to show a communication error, running a printhead cleaning cycle through the printer’s maintenance menu might help.
