Fix: Canon Scan Error Code 2,140,21

This is the error code which i received  while setting up a customer’s scanner. The solution and fix that worked me is very easy and simple, but before i discuss the fix i would like to brief the readers  on the back ground of this issue.

The customer intended to set his scanner up so that he could use the scanner to scan multiple  documents into a single PDF.

This was a canon multi-functional printer, initially connected  via USB. And to make things easier i wanted the customer to use the Canon IJ Scan utility because it had great features to achieve what the customer wanted.


So i instructed the customer to connect the printer to his wireless router, which was successful.

Then we ran the printer software from the Canon site to download and set the printer up on the PC. (Windows 8.1/64-bit).

Then we downloaded the IJ Scan Utility and attempted to scan multiple documents which resulted in error 2,140,21, 2,140,21

So what we did to fix the issue was to hold down the stop button on the printer for 10 seconds and then released it which immediately fixed the issue.
