How to Fix Canon Printer Error Codes?

There is a long list of Canon printer error codes that you may encounter while using it. If you are a regular user, you must know about these errors to resolve them within minutes. Here, we are going to explain each code with its causes and solution. This way, you will be able to understand the main reason why it occurs. Let’s get started!

Error Code B200


This error occurs because of a faulty or worn-out printhead.

Way to Fix the Error

You can execute the printer’s ability to clean the printhead. The option can be found in the maintenance section of the setting menu. Once done, take the printhead out and use an alcohol solution and cotton swabs to clean every connector and contact point. Let the printer rest without power for at least half an hour. Place the printhead back in its original position. It will remove any software glitches and error caches.

If the error persists, replace all the ink cartridges and install a newer version of the driver software. If the problem remains unchanged, your printhead is beyond repair; you need to replace the printhead.

Error Code B203


This error is relatively standard and hard to pinpoint; it may require expensive repair jobs and components.

It indicates that the printhead has lost communication with the control board.

Way to Fix the Error

As the problem is a little tricky and hard to pinpoint, good timing is required to solve this issue and will only work with the primary causes of B203 errors. First, turn off the printer and unplug the power cord. Let the printer rest for 15 minutes. After 15 minutes, turn on the printer while randomly opening and closing the lid of the printer. By doing this, you may be able to resolve the error, at least temporarily. You need to use a quality set of ink cartridges to avoid this error.

Error Code B504


This is one of the rare errors that are related to the printer itself. This error occurs when the printer’s protective mechanism fails to protect the sensitive components, such as resistors, from overheating. Because of it, the nozzles of the printhead get clogged, and the printer won’t be able to function normally.

Way to Fix the Error

Turn off the printer, unplug the power cord, and open the front cover. After opening the front cover, the printhead carriage will be visible. You can move the printhead carriage by hand, but you must be gentle. Due to overheating, the ink cartridges may not work. Use rubbing alcohol and cotton swabs to clean the nozzles and the connector of the printhead. Place new ink cartridges in the printhead and reassemble the printer.

Error Code C000


This error occurs due to three reasons.

  • Incorrectly installed ink tanks.
  • Obstruction in the paper feed path.
  • Packing materials such as tape or propylene are not disposed of properly.

A specific orange tape is used during shipping to hold the ink inside the ink tank. It is one of the most common causes, so you must remove the orange tape before heading to the printing job.

Way to Fix the Error

You must take out the ink cartridges and place them correctly back in their original position. While pulling out the cartridges and putting them back, don’t use excessive force. Lastly, open up all the covers in the front and back of the printer to check if a paper is stuck in the printer or any other moving part. You can use your hands to remove that jammed paper.

If everything fails, the printer may require a hard reset; you need to turn off the printer and unplug the power cord. When you plug the power back in, keep pressing the power button for the printer to initialize itself.

Error Code E03


This error pops up when a paper gets stuck in the printer.

Way to Fix the Error

To fix this issue:

  1. Turn off the printer and unplug all the cables.
  2. Check the Canon Printer User Manual to get an idea about all the possible locations where the paper can get stuck.
  3. Open up all the covers protecting the rollers.
  4. When you locate the jammed sheet, pull out the paper gently so that the paper won’t get torn.

Error Code E04


The error occurs when an incorrect ink cartridge is installed or placed in the printer.

Way to Fix the Error

You have to follow the same process as mentioned earlier. You need to turn off the printer and unplug all the cables. After removing all the papers from the paper tray, open up the cover protecting the ink cartridge. Remove the cartridges one at a time. If you have recently replaced the ink cartridges, the chances are that the ones you have installed are incompatible with your printer. Next time double, check the new ink cartridges.

Error Code E05


This error occurs when the printer cannot recognize one or all the cartridges.

Way to Fix the Error

This error is somewhat similar to error E04. The first thing you need to check is whether all the ink cartridges are correctly installed or not. Pull them out and place them back. You will hear a click when you put the ink cartridges back.
