mx452 stops scan in middle of job code 2.157.50

[BC9392]

I have MX452 Printer.  It's connected to laptop through usb cable. 

IJ Network Scanner Selector Ex is disabled so I do not scan over the network.

Everything works fine.BUT

It starts scanning documents fine but halfway through a large document scan it says:

       Can not communicate with scanner for these reasons:

             Scanner is turned off  (it's not)

             It is disconnected from LAN    (How do I know)

              Signal strenth is poor   (I'm not using wireless network)

              Network connection prohibited by security software  (NO - why does this happen in mddle of scan job)

              Different scanner on networkis selected.  (this only scanner)

 Code is 2.157.50

Canon does not support MX452 printer anymore even though this code is relevant to other printers and canon says call customer support.

Any suggestions on troubleshooting.

Hi BC9392,

To better assist you additional information is needed. Please respond with the information below:

• How long is the USB cable that's going from the printer to the computer?
• What version of Windows are you running on your computer?
• When scanning are you using the operation panel of the printer or the IJ Scan Utility on the computer screen?
• With the IJ Scan Utility program open what does it say next to Product?
• What type of security or anti-virus are you running on your computer?
