Canon Pixma Pro 100, flashing yellow light, getting B200 support code message

Purchased printer over 3years ago.  Only printed a small handful of things.  All images came out great. Didn't really have a need for printing anything since then until today. 

I plugged in, powered it on, my Windows 10 PC recognized printer...everything looked good up to the point I noticed the yellow light flashing non-stop. So, I decided to open the top tray to examin the ink cartridges.  Anticipated ink tray would move to center position...but never does.  Infact, the entire printer is silent after I power it on.

Does ink bind up over time in these printers?  Will issues arrise for not using a printer for a long time?  I did move into a new home.  Not sure if rattling/vibrations from a moving vehicle can cause some issues internally.

Is my printer doomed?  Anyone have any suggestions?  I imagine servicing this thing is too costly and would be cheaper to buy a new one...which I don't really want to do.

Update...I can't believe this worked, but I turned it off and unplugged it and then plugged it back on/powered it on several times...and it magically started working again. 

Printing now...now to see if ink somehow held up over the years.

-edit-

amazing, it works great still.

This worked for a short while. But the yellow flashing happens more frequent now. The ink cartridges are lit red indicating needing replacement even though they are full. Does anyone have a suggestion? Thank you in advance.
