I'm trying to update my PRO-10 with the downloaded Canon utility via USB, but it fails every time. After the fail I get the message below and the amber alarm gives off the 3 flash warning, which is related to jammed paper and print doors being open, none of which are open, jammed or applies here.
I'm running OS Catalina 10.15.7 on a relatively new iMac.
Have tried switching cable to each USB input and restarting printer...no luck.
There are a number of threads on this issue.
Run a nozzle check. If the reported FW is lower than 2.0 you are OK.
