Hi, Joe3!

So that the Community can help you better, we will need to know whether your computer is the only one with access to the printer or if there are other computers/mobile devices trying to access it. That, and any other details you'd like to give will help the Community better understand your issue!

If this is a time-sensitive matter, our US-based technical support team is standing by ready to help 24/7 via email at http://Canon.us/SupportCF or by phone at 1-800-OK-CANON (1-800-652-2666) weekdays between 10 AM and 10 PM ET (7 AM to 7 PM PT). We also encourage you to check out our Knowledge Base at that same link for answers to common questions.

Thanks and have a great day!

I am the only computer user on the network! Canon printers are no bargin if they canot recognize or "count" the number of computers on a given network.

Hi Joe3,

Resetting your network may resolve the issue being experienced. To do this, please follow these steps:

1. Turn off the printer and unplug the power cord, then turn off your computer.

2. Unplug your wireless router for at least 60 seconds, then plug it back in.

3. Wait 5 minutes, then plug the printer back in, and turn it and the computer back on.

Please attempt to print again. If you still experience difficulty, we ask that you please contact a Canon technical support representative here for further assistance. A representative will be happy to assist you free of charge.
