There are several reasons why a Canon printer may go offline:
Connection issues: The most common reason for a printer to go offline is due to connectivity problems. This could be due to a loose USB cable, a disconnected Ethernet cable, or a weak Wi-Fi signal.
Paper jams: A paper jam or other hardware issues can cause the printer to go offline. Check for any error messages or blinking lights on the printer to identify if this is the case.
Driver issues: If the printer driver is outdated, corrupted, or not installed correctly, the printer may not be able to communicate with the computer, resulting in it going offline.
Printer settings: Incorrect printer settings, such as incorrect paper size, print quality settings, or tray selection, can also cause the printer to go offline.
