How Do I Solve the Canon Printer U140 or U150 Error


No technical device is free from technical glitches, and this applies to Canon printers as well. One of the most common problems that you face while using the Canon printer is the error problem – the U140 or U150 Error. This error message is an indication that there is something wrong with the Canon printer cartridge. Here, let us try to find out the causes of the error and how to fix it.


  • The U140 or U150 error appears when the printer is not able to read the cartridge installed in the device. It means “The ink cartridge cannot be recognized.” Usually, this happens when a non-Canon ink cartridge is used. The Canon printer is programmed to protect the printer from low-quality cartridges.
  • You can also face this problem when the gold contacts on the front of your cartridge are blocked by ink or dirt.
  • The error message also appears when the cartridge is not installed properly.

How to fix the Canon Printer U140 or U150 Error?


  • Open the cover and remove the relevant cartridge
  • Turn off the power of the printer
  • Check whether the correct cartridge is installed or not
  • Or Clean the gold contacts on the front of the cartridge using a dry tissue
  • Put it back on the correct slot and put the power on

If the message still appears, then try the following solutions:

Method 1

  • Open the output tray
  • Turn on the printer
  • Open the scanning unit
  • The cartridge carriage will move towards the center
  • Now you open the inner cover. Remove all the cartridges.
  • Take the problematic ink cartridge from the printer (This you know because the cartridge with the problem will remain off)
  • Now remove the protective film. You need to peel or tear off the orange tape along the dotted line.
  • Now put back the ink cartridges in the correct slots. You will see a red indicator light showing that they are properly inserted
  • Close the inner cover
  • Close the scanning unit
  • The Canon printer will start a print head cleaning cycle on its own
  • When the cleaning cycle is finished the printer is ready to use

Method 2

  • Install a new cartridge
