Canon Error 1403 — What It Means & How to Fix It
Updated July 2026 · Independent PrinterCare USA support guide
Canon error 1403 is one of the most frustrating messages you can see because it often appears after you have just replaced cartridges or performed maintenance. This error specifically tells you that the printer's internal sensor cannot verify the print head type matches what the printer expects, which usually means either a compatibility issue or an improper installation.
The good news is that this error is almost always fixable without calling Canon directly or buying new equipment. In most cases, you are dealing with a simple installation issue or a temporary communication glitch between the cartridge and the printer's logic board. This guide walks you through the real solutions that technicians use every day.
How to fix it — step by step
- Power cycle your printer completely. Turn off your Canon printer using the power button and unplug it from the electrical outlet. Wait for at least thirty seconds to allow the internal capacitors to fully discharge. Plug the printer back in and power it on, then wait for it to complete its startup cycle before attempting to print.
- Remove and reseat the print head cartridge. Open your printer's access panel or cartridge door according to your specific model's manual. Grasp the print head cartridge firmly and pull it straight out toward you until it is completely free. Inspect the cartridge contacts for any dust, debris, or ink residue, then carefully reinsert the cartridge in a straight line until you feel it click or lock into position.
- Check cartridge compatibility with your model. Verify that the print head cartridge you installed is the exact model number recommended for your specific Canon printer model. Visit Canon's official website and enter your printer model to confirm which cartridge types are compatible. If you are using a third-party or refurbished cartridge, cross-reference the part number to ensure it matches an authentic Canon specification.
- Clean the cartridge contact points. Remove the print head cartridge again and use a soft, lint-free cloth slightly dampened with distilled water to gently wipe the metal contact points on both the cartridge and the printer. Do not use rubbing alcohol or tap water, as these can cause electrical corrosion. Allow the contacts to air dry completely for two minutes before reinserting the cartridge.
- Run the printer's cleaning cycle. Access your printer's maintenance menu through the control panel or your computer's printer settings dialog. Select the option for head cleaning or cartridge maintenance and allow the cycle to run completely without interrupting it. This process can take several minutes and will help establish proper communication between the cartridge and the printer.
- Check for firmware updates on your printer. Visit Canon's support website and search for your printer model to download any available firmware updates. Follow the on-screen instructions carefully to install the update, which often includes fixes for sensor recognition errors. Your printer will restart automatically after the update completes.
- Verify the cartridge is the correct color or type. For color printers, confirm that you have installed the cartridge in the correct slot position for its color designation. Some printers will reject a magenta cartridge installed in the cyan slot, triggering this exact error. Cross-check your cartridge colors against the label diagram inside your printer's access panel.
- Consider professional remote diagnostics if the error persists. If you have completed all previous steps and error 1403 still appears, a remote technician can connect to your printer remotely to read detailed error logs that will pinpoint the exact cause. Many professional repair services offer this diagnostic service for around $49 and can often resolve the issue during that same remote session.

Frequently asked questions
Does error 1403 mean my print head is broken?
Not necessarily. Error 1403 is almost always a recognition or communication issue rather than physical damage to the print head itself. The error indicates that your printer's sensor cannot verify the cartridge type, which is usually caused by improper installation, incompatible cartridges, or dirty contact points. Physical print head failure would typically produce different error codes or fail during the actual printing process.
Why does my Canon printer show error 1403 after I bought a refurbished cartridge?
Refurbished or third-party cartridges sometimes use slightly different electronic chips that do not match your specific printer model's sensor expectations. Check the cartridge packaging to confirm it is designed for your exact printer model and not a similar model number. If the refurbished cartridge is incompatible, you will need to purchase the correct genuine or certified compatible replacement cartridge.
Can I fix error 1403 without removing the cartridge?
In some cases, a full power cycle of your printer while completely unplugged for thirty seconds can reset the cartridge communication without touching anything inside. However, if the error persists after a power cycle, removing and reinstalling the cartridge is the next required step. This gives you the opportunity to clean the contact points and ensure the cartridge is fully seated in its slot.
What should I do if error 1403 appears on multiple cartridges?
If the error occurs with multiple different cartridges, the problem is likely with your printer's sensor or internal logic board rather than the cartridges themselves. Try running a full cleaning cycle and updating your printer's firmware first. If error 1403 persists across several cartridges, contact a professional repair technician or Canon support, as the printer may require internal service or replacement.
