Hi @5487LSA,
Welcome to the HP Support Community!
I understand you're facing issues with your HP OfficeJet 8015e All-in-One Printer, specifically error code 71.02.4A, which usually points to an ink system issue. Since you've already tried troubleshooting for this error and are now seeing a cartridge error, let's go through some steps to help resolve it:
Troubleshooting Steps
🔹Restart the Printer– Turn off the printer, unplug the power cord, and wait for about 60 seconds. Then, reconnect the power cord and turn the printer back on to check if the error persists.
🔹Reinstall the Cartridges– Open the printer cover, remove the ink cartridges, and reinstall them securely. Ensure they click into place properly.
🔹Remove Protective Tape– If you're using a new cartridge, make sure the protective tape or seal has been removed before installation.
🔹Check for Damage– Inspect the cartridges for any visible damage. If you notice any leaks, cracks, or defects, replacing them may be necessary.
🔹Update Printer Firmware– Ensure your printer’s firmware is up to date. You can check for updates on the HP Support website.
🔹Clean Cartridge Contacts– Power off the printer, unplug it, and remove the cartridges. Using a lint-free cloth, gently clean the gold-colored contacts on the cartridges and inside the printer. Avoid touching the ink nozzles.
🔹Perform a Hard Reset– While the printer is still on, unplug the power cord from the back of the printer. Wait for 60 seconds, then plug it back in and turn the printer on.
