HP 6600 printer issue

[DavidP52]

Ink support system failure, print head missing or not detected, or incorrectly installed.  Unit stopped midway during print job with this error message.  Changed all ink cartridges to new ones, cleaned print heads with isopropal alchohol, still same error message.

Welcome to the HP Support community.

Remove and reinsert the ink cartridges

1. Open the door to access to the ink cartridges.

2. Wait until the carriage stops moving before you continue.

3. Push the ink cartridge to remove it, and then push it into its slot until it snaps into place.

   

4. Repeat these steps for the other three ink cartridges.

5. Close the ink cartridge access door.
