My HP DeskJet 3755 printer is displaying a low ink light.  I replaced both cartridges with new ones supplied by HP, but the light is still blinking and refuses to print.

Hi @Diane416,

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 Product. Not to worry I will help you to get a resolution to resolve the issue.

If the low ink light is still flashing even after replacing the cartridges, there could be a few possible issues:

• Cartridge Installation: Ensure that the new cartridges are properly installed. Remove them and reinstall, making sure they click into place and are seated correctly.
• Ink Cartridge Protection Tape: Verify that all protective tapes or covers have been removed from the new cartridges. Sometimes, leftover tape can prevent proper cartridge function.
• Printer Reset: Try resetting the printer. Turn it off, unplug it from the power source for about a minute, then plug it back in and turn it on.
• Ink Levels: Check the ink levels using the HP Smart app or printer control panel to confirm that the printer recognizes the new cartridges.
• Printer Maintenance: Perform a printer maintenance routine. This may include cleaning the printhead, which can sometimes resolve issues with cartridge recognition. Refer to your printer’s manual for instructions on how to do this.
• Firmware Update: Check if there are any available firmware updates for your printer. Sometimes, an outdated firmware can cause such issues. Update the firmware on an HP printer
• Cartridge Compatibility: Ensure that the cartridges are compatible with your specific printer model. Using incorrect cartridges can sometimes lead to these types of issues.
