Have canon mg7520 pixma printer with error message 1660

[Lwjacobs1]

After replacing the yellow ink cartridge, the printer says it cannot recognize it. I have tried all of the suggestions that I have seen posted. Removing the ink cartridges and unplugging the printer. But nothing has worked. And it won't print. Please help.

Hi Lwjacobs1,

The 1660 error is an indication that your PIXMA MG7520 does not recognize the ink tank, in this case, the yellow ink tank.

Please make sure there is no packing material left on the ink tank, as this will cause the 1660 error.

Reseating the ink tank and resetting your PIXMA MG7520 should have cleared this error.  Because it did not, please contact our support group using the following link:
