I solve mine (4 Yellow Flash + 1 Green) by pushing on the white gear, located at the end right inside, where the cartridges are cleaning. This help the movement of the gear, it was stuck or gem. Do this when you just turning on the printer, then you ear the cycle noise, Your fingers will sense the movement of the gear. Tips: Push the cartridges block to the left to let you enough space to put your hand inside.Now it work normally.

The user guide for that product says that 7 flashes means the printhead is defective and that you should contact Canon's customer care. If you've recently replaced the print cartridge(s), try putting the old one(s) back in. If the printhead is truly defective, there may be no choice but to contact Canon or replace the printer.

pls replace the colour catridge. bye
