Sprocket studio starts to print a photo, whirrs for a minute or so, then displays flashing red light and app shows an error message “replace cartridge” but the cartridge is stuck in the machine. Pressing the release tab only allows it to move 1/2 in. The cartridge was only half used previously,
Power cycling to reset printer just causes the same cycle to be repeated.
With more force, the cartridge was removed and replaced. The same cycle repeats. it was then replaced with a brand new cartridge, and the same happened again. So it seems to have ruined two good cartridges. It looks as though there is a drive roller pressing against the coloured film in the cartridge that is making it difficult to remove.
