Question about HP LaserJet 4350 Printer

Where are the paper path sensors?

We are having the same problem and when we send them in for repair they charge us lots of money to "Release the sensor".... Can we do this ourselves? Where are the sensors located. the error is 13.2.
Thanks

ITS RIGHT IN THE MIDDLE WHERE THE PAPER EMERGES FROM A ROW OF ROLLERS TO TRAVEL UNDER THE DRUM/TONER CARTRIDGE. FLAG IS A VERY LITTLE BLACK PLASTIC LEVER IN THE CENTER THAT IS GENTLY SPRING LOADED TO POP BACK UP AFTER THE PAPER PASSES BY. USE A FLASHLIGHT.

    SHOOT THE SENSOR AREA WITH A CAN OF AIR TO CLEAR TONER. MAKE SURE THE PLASTIC FLAG MOVES FREELY AND SPRINGS BACK.

Paper jam 13.20 in tray 2 in printer hp 4015


Thank you for contacting FixYa with your printer inquiry.


This error message prompts when paper or obstruction holds a sensor switch or toggle open in the paper path. Paper can jam a sensor and make it think there is a jam when there isn't one.


Action:

  1. Start printer and listen for motor startup noises.
  2. Open top cover and remove toner cartridge and thoroughly check for small pieces of paper parts. Also locate the plastic sensor and inspect for proper movement.
  3. Open the back cover and remove the fuser by pinching on the blue release catches and pulling the fuser out. Should have an exit sensor - check for proper movement and/or obstructions.
  4. Remove tray 2 and make sure the paper adjusters are set to the paper size being used. Many times they go out of adjustment when paper is changed. Do not set to any.
  5. Fold a legal size or bond sheet of paper in half and then again the long way. We now have a tool that we can floss the paper path. Thread it through from above the tray 2 pickup and reach it from the top. Work it up and down while sliding it forth and back along the path. It should dislodge and clear the mystery obstruction.


It's possible the fuser has been changed out and the incorrect replacement has been installed. You will want to confirm the part numbers if so.


If the DC Controller has been changed you will want to confirm connections.


Hope this helps. Please keep us updated and remember to rate this answer.

A paper is stuck how do i release it?h


This error message is displayed by the printer when paper is jammed in one or more locations. In such a case, users are recommended to remove the jammed paper from the specified location. The entire paper path must be checked for any pieces of paper. To stop the message, open and close the top most cover of the printer. Lastly, verify the flags and the sensors. If the problem persists, the cause of the error message could be a broken sensor or sensor lever.

Troubleshooting paper jam


You probably have a small piece of torn paper jammed right up against the paper jam sensor. You'll need to open it up and check the entire paper path for it. Even a small piece of paper can trip the sensor if it's in the right place. If you can't get at the entire paper path, you may need to take the printer to a qualified computer repair shop and have it done. Most shops won't charge you a lot for this job, and it can usually be done while you wait.

My canon MP620 Paper Jam Pull out the Jam Paper Al


There are pieces of paper stock on the sensor, when the paper jam happened then you pull out the paper did you get the whole page of the paper or have missing pieces? open the paper guide, turn off and on the printer and observe the unusual objects in the roller, this error is caused by objects in the sensor.

Back cover alert keeps flashing


The black lines sound like it may be a contaminated fuser roller. Surface of one of these rollers is a Teflon coat. In time this wears away and the end result is toner build up that eventually transfers to the paper.A Photo Sensor is a switch that monitors the path of the paper thru the cycle of paper pick up all the way to exit of the paper from the out put. These switches open and close. when there is a paper jam and not all of the paper is removed fragments of the removed paper can be left behind. this can actually trigger an error of door open/close cover. The mentioned "two blue tabs" are the release point of the fuser upper roller that you toggle to move the roller up or release the downward pressure from the bottom roller. These are used to clear a paper jam . If you have access to a small flash light, look carefully in that area for fragments of paper. The "yellow triangle " is part of the warning label of the fuser cover stating that this is an extremely hot in temperature piece and to handle with care or touch with the power off and wait to cool prior to any inspection,. If there is no signs of fragments of paper in the area, a "sensor" flag might be stuck and blocking the photo sensor's light path, triggering the " Back Cover open" error.....hope this helps,Steve
