I have a Office Jet Pro 7740 printer and had to replace the Cyan cartridge. When I installed a new Cyan cartridge with warranty date of 2025/11, it started telling me that there is a supply problem with Cyan and also started complaining about Magenta cartridge not being compatible. I've tried all the tricks from other posts like pulling power cord and waiting 60 seconds and plugging back in, resetting the printhead at least 3 times and tried other brand new in box HP cartridges. Any help would be appreciated.

Hi @BradleyGZ,
Welcome to the HP Support Community.
I'd be glad to help you!
I understand that you are having issues with the cartridge error.
Perform the following tasks in the order given. Use the printer after each task to see if the issue is resolved.
Check the cartridge numbers- Make sure the cartridge numbers are compatible with your printer and country/region.
- Open the door or lid to the cartridge access area. Wait until the carriage stops moving before continuing.
- Check the cartridge labels and compare with the list of compatible cartridges for your printer in Which cartridges work with my HP printer?.
- Compare the labels on the cartridges with the labels on the carriage to check that all cartridges are in their correct slots.
- If you saw the error after moving your printer from one country/region to another, you might not find ink cartridges with the number you used to buy. In some cases, you need to contact HP Support for a regionalization reset.
- If your printer is enrolled in Instant Ink, the cartridges should be marked Instant Ink. The numbers may be different from the cartridges available from retailers, but your printer is designed to work with Instant Ink cartridges. See Solve problems with Instant Ink cartridges and enrolled printers for more help with Instant Ink cartridge errors.
- If you have an HP+ printer, see Can't print on an HP+ or Instant Ink enrolled printer for more help.
Note: HP+ printers require Original HP cartridges.
Make sure all the cartridges are firmly seated. If a cartridge is sticking out farther than the others, press it in.
Replace any incompatible cartridges. Go to the HP Store to purchase compatible cartridges.
