HP7740 setup - not recognizing color inks

[Jopageri]

Two issues.

1) My new printer (7740) is recognizing the black ink, but not the cyan, magenta, or yellow.  They don't seem to "click" in all the way and it keeps telling me to check them for leaks.  These are the inks that came with the printer, so are genuine HP inks.

2) I just checked online, and it says the warranty expired a month before I purchased it.  Not sure what this means?

Hi @Jopageri,

Welcome to the HP Support Community. 

I'd be happy to help you! 

I understand that you are facing issues with printing in color.

Perform the following tasks in the order given. Use the printer after each task to see if the issue is resolved.

Clean the printhead

• Use an automated tool to clean the printhead to restore print quality.
• Load plain white paper into the tray.
• On the printer control panel, swipe down on the touchscreen to open the Dashboard.
• Touch the Setup icon .
• Touch Printer Maintenance, and then touch Clean Printhead.

Check for issues with the ink cartridges

• Very low ink levels and using non-HP cartridges can cause print quality issues.
• Replace any non-HP or refilled cartridges with genuine HP cartridges. HP supplies are available from the HP Store and local retailers.
• HP cannot guarantee the quality or reliability of non-HP or refilled cartridges. Go to HP Anti Counterfeiting and Fraud Program for more information.
• On the printer control panel, swipe down on the touchscreen to open the Dashboard, and then touch the Ink Level Indicator icon .
• Check the ink levels and replace any low or empty cartridges.

• Rough handling of cartridges during transport or installation can cause print quality problems. Wait a few hours for the automatic servicing routine to complete, and then try to print again.
• If you have a defective HP cartridge, it might be under warranty. Go to About Original HP Cartridges for page yield and HP Limited Warranty information.
