Firstly you would need to check on wether the printer will print with any cartridge. Remove both cartridges and power the printer off from the center button at the back. Then insert only the black cartridge, wait for a solid yellow light and then raise the tray to print position and run a print. Does it print?
If yes repeat the procedure for the color. If you print with both then the machine just needed a restart. If you are still unable to print then please contact technical support at *Emails are not allowed*
