If multiple computers are using a printer, the printer may be locked for a period of time. Then you could get the error message “Another computer is using the printer” when you want to print a file with this printer. This means that the previous process did not release the lock.
Press “counter check” button on the control panel. Observe LCD display for information. Select “print list” from the LCD display to get a printed report. Retrieve the report from the printer, scan and email back to us.
Check1 Make sure that the printer is turned on. Check2 Make sure that the Wi-Fi lamp is lit on the front side of the printer. If the Wi-Fi lamp is off, Wireless LAN is inactive.

The easiest way to connect the Canon printer to the computer is via a USB cable. It`s the traditional method of connecting devices. One end of the USB remains connected to the printer, and the other must be connected to the computer`s USB port.
Make sure that the printer`s USB cable is properly connected from the printer to your PC. If your USB isn`t recognized, see Automatically diagnose and fix Windows USB problems. Check the wireless connection (for wireless printers).
This message is nothing to worry about. Windows “manages” your default printer by changing the default printer to the one you use most often. When you set the default printer manually, windows is simply telling that it will not change it automatically.
Make sure that the printer`s USB cable is properly connected from the printer to your PC. If your USB isn`t recognized, see Automatically diagnose and fix Windows USB problems. Check the wireless connection (for wireless printers).
Check Cables and Printer USB Ports

Check all cable connections (including the power cord) on the printer side. If the printer does have power and you`ve properly connected the communication cable, but the printer is still not recognized, try switching to a different USB port on the PC.
