Hi @Dottybates2003,

Welcome to The HP Support Community.  

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

I understand you are getting the "E0" error on the HP DeskJet 2842e typically indicates an issue with the ink cartridges. Since your account was canceled, and you're using replacement cartridges, here are steps to resolve the issue and information about returning unused ink:

Resolve the E0 Error:

Check Cartridge Compatibility:

• Ensure the cartridges you're using are compatible with the HP DeskJet 2842e.
• For this printer, the required cartridges are usually HP 67, HP 67XL, or HP 67XXL.

Reinstall the Cartridges:

• Turn off the printer and unplug it from the power source.
• Open the ink cartridge access door and remove the cartridges.
• Inspect the cartridges for protective tape over the nozzles and contacts. If present, carefully remove it.
• Reinsert the cartridges firmly into their respective slots (color on the left, black on the right).
• Close the access door and reconnect the printer.

Clean the Contacts:

• Power off the printer.
• Use a lint-free cloth slightly dampened with distilled water to gently clean the gold contacts on the cartridges and inside the printer.
• Let them dry before reinserting.

Perform a Reset:

• Unplug the printer while it’s on.
• Wait 60 seconds, then plug it back in and turn it on.

Update Firmware: Update the firmware on an HP printer

• Ensure your printer has the latest firmware. Use the HP Smart app to check for updates.

Test the Printer:

• Perform a test print. If the issue persists, the cartridge might be defective or incompatible.
