Red light is on

My Instax 7s won’t take any pictures only make a click noise goes blank then The red lights starts blinking I have brand new batteries and new film in what else should I do ?

I got mine to work by changing the port from USB001 to USB002 prints great now, there is problems with installing on windows 8, you have to disable driver verification or the driver won't install.

Good printer don't give up on it.

Check the red ink printer cartridge. also check the settings

If the round red light you describe is a circle of dots that indicates a developer change is due. This needs to be done by a technician but the machine should work fine without doing the developer change.

It's possible magenta ink to be finished, or the print head is dirty and it has dry ink on it. You must clean it with hot water. You must use the printer from time to time to avoid to dry the ink cartridge or print head.

The lights continually flashing indicate a paper jam or the printer being out of ink. Check/clear any paper jam and verify the ink cartidge is set correctly.
