help!!! I have a canon pixma mg3510 and those 3 little orange lights blink 5 times: alert, cl and bkI already pressed the stop button for more than 20 seconds and nothing. I already refilled the black and color cartridge and nothing. clean the chip that connects the two cartridges with the printer and nothing.worst of all is that the cartridges have always been empty since I bought it but it has only been a month and it won't let me scan anything !!! This has never happened before. and I think I will have to buy new cartridges to see if it works but first I need to try everything.WHAT DO I DO ??
