Message: The printhead appears to be missing , not detected, or incorrectly installed

[Katarzyna77]

I have an HP Officejet 6600 printer.  Serial number [edit].  I was getting a message stating " The printhead appears to be missing, or not detected, or incorrectly installed".  I replaced all cartriges, but message still pops up.

Hi @Katarzyna77 ,

Welcome to the HP Support Community.

I'd like to help!

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

Reset the printer

Reset the printer to recover from printer errors or failures.

1. If your printer has a rechargeable battery, remove it.

2. Press the power button to turn off the printer. If the printer does not turn off, disconnect the power cord from the printer.

3. Unplug the power cord from the power source.

4. Wait 60 seconds.

5. Connect the power cord directly to a wall outlet and to the printer.

6. Turn on the printer to complete the reset.

Update the printer firmware

HP regularly releases new firmware versions with printer enhancements or issue fixes. Update firmware on a regular basis to make sure you are getting the most out of your printer.

• Update from the printer control panel: Many HP printers with touchscreens or menus can connect directly to HP to find and install updates. Make sure the printer is on a network with an active Internet connection. If the printer is connected with a USB cable, use one of the other options.

  On the printer, locate the Product Update or Check for Updates menu by pressing the HP ePrint icon or button (

   or 

  ). Or open the Setup, Service, or Settings menu, select Preferences, Printer Maintenance, or Tools, and then select Web Services, Printer Update, or LaserJet Update.

• Download updates from HP Customer Support: With the printer turned on and connected to the computer or a network, go to HP Software and Driver Downloads to check for and install available updates listed under Firmware.

• Install updates through the HP Smart app: Open the HP Smart app, and then create an account or sign in. If you do not have HP Smart, download it from 123.hp.com or your app store. After adding the printer, click the printer image, click Printer Home Page (EWS) or Advanced Settings, click Tools or Web Services, and then click Printer Updates.

  Click here for the remaining steps.
