I have the same exact issue but with the Pixma Pro 100
B200 error and got a new printhead and it doesn't move
I believe we talked on another forum several months ago about this haha
Finally got a new printhead
I assume the same steps once I get the covers off?
Have disassembled several printers...
I've used this printer about 6-7 times only since I got it
It usually sits at a location plugged in
I just tried using it about a week ago after it sitting about a couple of months and when I pressed the power button it started doing those lights since
Tried different power sockets and cables...
