HP Photosmart C4580 print cartridge(s) missing or not detected

Actually you can try to convince the printer that the cartridge is ok by entering the service mode. To do that press buttons in the following sequence:

• Power and Cancel simultaneously, then
• Blue, Green, Gray buttons, in turn.

Congrats! You entered the service mode. Now you can read and edit some of the printer settings. Watch the LCD display, it should say sth like:

Now, the color buttons mean:

• Blue: next
• Gray: previous
• Green: enter

Which allow you to browse the menu and options.

In order to cure your cartridge press Blue once. You will see Information Menu displayed. Enter the menu by pressing Green. Go to Pen supply, level of Ink (LOI) submenu by pressing 11 times Blue and enter it by pressing Green. Then you can see some ink levels on the display. At this point your job is done. Press Cancel 3 times – it will quit the service mode. And you will notice that the nasty message about the cartridge being missing is gone.

Putting it all together, to reset the message press:

• Power and Cancel simultaneously,
• Blue, Green, Gray, in turn,
• Blue
• Green
• 11 times Blue
• Green
• 3 times cancel.

I found these service codes on the web and accidently i figured out that viewing the ink level resets the nasty message. The drawback is that you need to reset the printer pretty much every print job.

Process worked except for the button functions. The "Enter" command is located on the "OK" button and not on the green. Once I figured that out, I followed the rest of the instructions and "viola", problem solved! Thank you very much!

You Rock!! I'm a homeschooling mom and I desperately needed my new printer cartridges to work. For some reason I had to follow the steps twice, because it reverted back to the error after a couple seconds, but now it is as good as gold! I'm impressed, to say the least!

Thank you very, very much.  Worked fine, but had to do the full procedure 3 times to clear the error.
