PIXMA MG3620 Green and orange warning lights blinking

[Kat5]

When I turn on printer, the green & orange warning lights blink one after another. It does it 2x & then happens all over again. Please help me trouble shoot. Thanks a lot.

Hi Kat5,

To resolve this error, please clean the encoder/timing strip inside of your PIXMA MG3620.  To do this, please follow the steps outlined in this Knowledgebase article:

Thanks so much for that tip- Patrick, that worked!! I will try printing now and hopefully everything works out. Thanks again.

Just had this same issue, linked knowledgebase article resolved issue. Appears just a tiny tiny smudge will cause this problem.
