A:AnswerNo, the printer will not print in black and white if the color cartridges are empty. It gives you an error and you have to replace the empty cartridges.
A:AnswerNot sure about cloud, but if you can display the cloud photo on your device you should be able to print it.
The printer has SD card slots, so Yes you can print from an SD card
A:AnswerTry removing all the cartridges and reinstalling them. If that doesn't work you can do a reset of your machine. Seems I saw the procedure in the tech info.
A:AnswerI have the same issue with mine. When the photo black cartridge is empty, it won't even allow me to print a sheet with just text on it. Really a bummer and I'd love it if someone else has a solution to this. Yes the cartridges are in the right place.
