PIXMA TR7020a Support code 7700

[Ccampbe1]

I have gotten an Support code 7700 on my Canon 7020a. It says I'm supposed to turn off the machine and contact the service center.  How do I do that and what is this code?

This sounds just like the "ERROR" I got on my MG2522.  I've had two of em - both threw the same B200 "error" message to take it to a service shop.  Every shop I call says "it aint worth repairing", and you cannot buy whatever part to fix it yourself - Canon won't sell you the part. I have a hunch it isn't actually a failure - it's a firmware built-in  "F YOU" after so many pages to force buying another.  I won't - I'm informing all friends and family DO NOT EVER BUY A CANON HOME PRINTER!
