Supply problem for magenta ink cartridge for HP 7740 printer

[Varina11]

How do I fix a supply problem error message for my HP 7740 printer for my magenta ink cartridge? I have replaced 2x with a genuine HP 952 magenta ink cartridges. I’m ready to change brands because this makes no sense. Has anyone gotten past this error message?

We're thrilled to have the opportunity to assist you and provide a solution.  

If you are encountering supply problem error messages for the magenta ink cartridge in your HP OfficeJet Pro 7740 printer, follow these troubleshooting steps to try and resolve the issue:

Check Cartridge Compatibility: Ensure that you are using the correct cartridge model, which for your printer is HP 952 magenta ink cartridge.

Verify the Cartridge: Make sure the cartridge is genuine and not damaged. Fake or damaged cartridges often cause error messages.

Reinstall the Ink Cartridge: Sometimes removing and reinstalling the cartridge can fix the error. Follow these steps:

• Open the printer cover.
• Remove the magenta ink cartridge.
• Check that the cartridge and its contact area inside the printer are clean and free of any obstructions.
• Reinsert the magenta cartridge firmly into its slot.

Clean Cartridge Contacts: Clean the electrical contacts on the ink cartridge and inside the printer.

• Turn off the printer and unplug it.
• Remove the ink cartridge.
• Use a lint-free cloth moistened with distilled water to gently wipe the contacts on the cartridge.
• Use a clean and dry lint-free cloth to wipe the cartridge contacts again.
• Let the contacts dry completely before reinserting the cartridge.

Update Printer Firmware: Sometimes an outdated firmware version can cause cartridge recognition issues. Update your printer’s firmware:

• Visit HP Software and Drivers and search for your printer model.
• Download and install the latest firmware update available for your printer.

Reset the Printer: Conduct a printer reset to clear any existing errors.

• With the printer turned on, unplug the power cord from the printer.
• Unplug the power cord from the outlet.
• Wait for about 60 seconds.
• Plug the power cord back into the outlet and then back into the printer.
• Turn on the printer. 

Hope this helps! 

Take care, and have an amazing day!

I have done this 3 times. I only use genuine HP cartridges and this far I have used 1 magenta cartridge purchased as a single cartridge to replace- no success and then a color pack of 3 cartridges. I continue to get this message. I spent a lot of money for the printer and the genuine HP cartridges. 

What else can you suggest to fix this issue?? I’m thinking HP is no longer providing a quality product or helpful tech support without charging extra.
