Pixma MG7720 ink lamp won't light up with Canon ink cartridge

On my MG7720, I got error 1660 for not recognizing an ink cartridge. I re-installed the (official Canon brand) ink cartridge and noticed the ink lamp doesn't come on when it's fully installed (it clicked in and all). Anyone know what the problem is? Is it the carriage? It's done this with multiple cartridges. Does anyone sell replacement carriages / how much do those cost / are they difficult to replace?

It seems to me like the two left pins (of the five) on the PGBLK aren't pushed down enough. If I put a lot more pressure on it, the lamp does light briefly. Makes me think it's the carriage.IMG-2797.jpg

Thanks!

Hi Nieb626,

The pins should retract when the ink tank is inserted.  Because they are not, it would appear that your PIXMA MG7720 would require service.  If your PIXMA MG7720 was purchased less than a year ago, please contact one of Canon's Technical Support Representatives via phone or chat to obtain your in warranty options.
