Door open error even thou door is closed - HP LaserJet 1300 Printer

There is a black sensor that detects when the door is closed, and an actuator that the sensor either sees or doesn't see. If this sensor is dirty, it might not be seeing the actuator. It could also be broken or knocked out of place.

Sometimes Door open error shows in printer even if it is closed .

Follow This steps to Fix Open Door Error Message:-

*Close the cartridge access door completely.
*Check the cartridge door for obstruction.

*Restart the Print Spool Device.
*Restart the computer.Restart the Printer.And If you are using Brother Printer And You Encounter With Brother Printer In Error State Windows 10 Issue then Read The Blog I Am Mentioning above.

This could be caused by a wiring mistake when the alarm was put on.
yes it can be something to do with your alarm.

There is a switch that should "close" when the door closes.
But, that switch either is damaged, or it is not sending the "now closed" signal to the printer.

Check that there is no obstruction blocking that switch, nor any dust plugging it up.

Hi

Error CL appears when the dishwasher control detects door switch is open or door is open. You'll have to open the door and check the continuity of the door switch. If the door seems to be closed then it is the control has detected an issue with the door latch. Check the door latch & seals to make sure door is closing fine. Unplug the dishwasher from power outlet and wait for 10-15 minutes. Restart the dishwasher and check if the error is still there. If error still appears then you'll need to repalce the door switch/door latch. Hope this helps... Please post back for further assistance.

How do I resolve the error message "Printer Access Door Open" (error code 3501 or 3609)? Published 08/25/2010 11:38 AM ' Updated 01/07/2011 08:40 AM ' Answer ID 1467 How do I resolve the error message "Printer Access Door Open" (error code 3501 or 3609)? To resolve this error, close the printer access door. The printer will not operate while the door/cover is open.

If the error continues even after you close the printer access door, power cycle the printer:

1. Turn off the power (press the On/Off button on the printer).
2. Unplug the printer power cord from the back of the printer.
3. Wait approximately 30 seconds.
4. Plug the printer power cord into the back of the printer.
5. Turn on the power to the printer.

i also have the same problem, anyone know the reason? thanks

Hi there
This is only the sencor or a switch needs cleaning or replacing just have a look how it closes there be a sencor or a switch.

The problem here sounds like the door switch, located in the door jam. It is fairly easy to replace, with usually one or two screws holding it to the body. Once removed, you'll see the two wires connecting it to the electrical system. To verify this is the problem, short the two wires together and see if it the problem clears up. If so, replace the switch and enjoy not having a passenger door warning anymore! :)

I hope this helps, and please let me know if you need any further assistance in this matter. :)

A simple test is to place a piece of bread in the microwave ( it heats up very fast) and then if your microwave was actually ON and generating RF, the bread would get hot very fast.. If it remains cool then only the fan is on. It appears that you may have a faulty door switch thou because once you open the door, your microwave should be off..

Are you sure the VENT is not on? That blower will operate regardless of the door open or closed so you must switch it OFF.
