Canon Printer Cannot Communicate With Printer

by

When your Canon printer shows the error “Cannot communicate with the printer”, it means your computer is unable to establish a connection with the printer. This issue is common in both USB and wireless setups and can be caused by driver errors, network problems, offline status, or incorrect configurations.

This guide provides step-by-step solutions to resolve this error on Windows and macOS.

Determine the Connection Type

USB Connection
  • Direct cable from the printer to the computer.

WiFi or Network Connection
  • Both the printer and computer must be on the same local network.

Ethernet Connection
  • The printer is connected via LAN cable to a router or switch.

Basic Checks

Power and Status
  • Ensure the printer is turned on and not showing any errors on the screen.
  • Check for blinking lights, paper jams, or ink warnings.

Restart Devices
  • Turn off your printer, computer, and router/modem.
  • Wait 30 seconds, then restart everything.

Fix USB Communication Issues

Check the USB Cable and Port
  • Use a different USB cable and port.
  • Avoid using USB hubs-plug the printer directly into your PC or Mac.

Reconnect the Printer

Windows:

  • Go to Control Panel > Devices and Printers.
  • Remove the Canon printer, unplug the USB cable, then reconnect it.

macOS:

  • Go to System Settings > Printers & Scanners.
  • Delete and re-add the Canon printer using the + button.

Fix Wireless Communication Issues

Confirm Printer Is Connected to WiFi
  • On the printer screen, go to Settings > LAN Settings > WiFi Status.
  • Print a Network Configuration Page to confirm the IP address.

Make Sure Computer Is on the Same Network
  • Ensure the PC/Mac is connected to the same WiFi network as the printer.
  • Avoid using guest or isolated networks.

Ping the Printer
  • On Windows, open Command Prompt: 
    ping [printer_ip_address]
  • On Mac, open Terminal and do the same.
  • If it fails, the printer is not reachable-reconnect it to the network.

Reinstall or Update Printer Drivers

Download the Latest Drivers
  • Go to Canon Support.
  • Enter your printer model and download drivers compatible with your OS.

Remove and Reinstall the Printer

Windows:

  • Control Panel > Devices and Printers > Remove Device.
  • Reinstall using Canon setup software or manually add it.

macOS:

  • System Settings > Printers & Scanners > Remove Printer.
  • Re-add it using the + button, and select the correct Canon driver (not AirPrint if advanced features are needed).

Set the Correct Printer as Default
  • Make sure you’re sending documents to the correct Canon printer, especially if you have multiple installed.

Windows:

  • Settings > Devices > Printers & Scanners > Set default.

macOS:

  • Printers & Scanners > Default printer dropdown.

Clear Print Queue and Offline Status

Windows
  • Go to Devices and Printers, right-click the printer > See what’s printing.
  • Cancel all print jobs.
  • In the same window, click Printer and make sure “Use Printer Offline” is unchecked.

macOS
  • Go to Printers & Scanners, open the queue, and cancel all print jobs.

Disable Firewall or Antivirus Temporarily
  • Security software can block printer communication.
  • Temporarily disable firewall/antivirus to test.
  • If it works, add the printer software to your firewall’s exception/allow list.

Use Canon Utilities

Canon IJ Network Tool or IJ Printer Assistant
  • Detects and configures Canon printers.
  • Can fix IP conflicts, reconnect the printer, and run diagnostics.

Canon PRINT App
  • Use on iOS or Android to check printer status, reconnect to WiFi, and manage print jobs.

Reset Network Settings on Printer
  • On the printer screen, go to:
    Settings > Device Settings > Reset Settings > LAN Settings Only
  • After reset, use Wireless LAN Setup or Easy Wireless Connect to reconnect to WiFi.

Firmware Update
  • Outdated firmware can cause communication failures.
  • Download and install the latest firmware for your model from Canon’s website.

When to Contact Canon Support
  • If none of the steps resolve the communication issue.
  • If the printer has hardware issues (e.g., broken USB port or WiFi module).
  • If error messages like B200, Support Code 6000, etc., appear.
  • Canon support can assist with diagnostics, warranty service, or repairs.
