If you own a Canon printer with an operational panel, you might have encountered the frustrating 1240 error. This error often occurs when printing documents without properly following Canon’s recommended instructions. However, fear not! In this guide, we will explore how to resolve and prevent the 1240 error on your Canon printer.
Follow the Instructions on the Printer Screen
The first and easiest solution to the 1240 error is to follow the instructions displayed on your printer’s screen. By performing the following steps, you can often resolve the error quickly:
- While the printer is powered on, lift the operational panel until it is parallel to the printer’s body. You will hear a click indicating it is in the correct position.
- Pull the output tray completely outside the printer. Avoid partial extension, as it may result in a “1259 output tray error”.
- Lift the paper support located at the edge of the output tray.
- Raise the support extension as well.
- Tap the OK button on the printer’s screen.
- If the error persists, try restarting your printer and repeat the process.
Clean the Sensor
Sometimes, the 1240 error occurs due to a clogged sensor underneath the operational panel. Paper dust or debris may hinder the sensor’s ability to detect the panel’s position accurately. To resolve this issue, follow these steps:
- Look for a small plastic lever, typically white in color, below the operational panel on your Canon printer.
- Clean the sensor area using a soft lint-free cloth, ensuring there are no foreign objects obstructing the sensor’s movement.
- Move the operational panel up and down several times to ensure it moves freely. The lever should be attached to the operational panel when it is opened.
Remove the Sensor to Bypass the 1240 Error
If the previous methods fail to resolve the 1240 error, you can bypass it by removing the sensor. However, proceed with caution, as this method should only be employed if necessary. Here’s how to bypass the error:
- Lift up the operational panel and access the lever.
- Use an X-Acto knife or a household knife to carefully remove the lever from the printer. Take care not to damage the printer or injure yourself.
- Close the operational panel and press the OK button on the printer’s screen.
- With the sensor removed, you can print normally without lifting the operational panel.
Note: Use this method only when printing on plain papers. Attempting to print on thicker papers with the operational panel closed may result in paper jams and potential damage to the printer. Removing the sensor will also void the printer’s warranty, so proceed at your own risk.
Conclusion
By following the steps outlined in this guide, you can effectively address the 1240 error on your Canon printer. Start by following the instructions on the printer screen, cleaning the sensor area and, if necessary, bypassing the error by removing the sensor. Remember to consult a printer professional or reach out to Canon Support if you encounter any difficulties. Enjoy hassle-free printing with your Canon printer!
