The system says that the rear door is open but no matter how many times I open and close it the message still appears. Is there another rear door that I don't know about?

The sensor for the back door is directly located on the underside of the motherboard. Check whether the sensor is dirty or else you might have to replace the motherboard.

Sometimes there is a small bit of paper stuck in there, or even a whole sheet, so check for a paper jam there. Always press start after clearing a jam, especially if you have to open the front cover, remove the drum and put it back in. I found that removing and reinstalling the drum solves a lot of print problems.

How to reset automatic sliding door on chevy venture van


The rear side door actuator control modules monitor the power sliding door positions at all times. Whenever the battery positive voltage supply to a rear side door actuator control module has been removed or the on-board diagnostics have been activated the power sliding door system(s) must be re-initialized. Re-initialize the right or left power sliding door systems using the following steps:
  1. Turn the ON/OFF switch for the power sliding door system to be re-initialized to the OFF position.
  2. Manually open the power sliding door completely.
  3. Manually close and latch the power sliding door.
  4. Turn the power sliding door ON/OFF switch to the ON position.
  5. Open the power sliding door completely using the B-pillar or overhead console OPEN/CLOSE switch.
  6. Close the power sliding door completely using the B-pillar or overhead console OPEN/CLOSE switch.

We keep getting a message -paper jam check open rear door. checked, no paper jam, opening and closing rear door will allow the print job to go through. It will work for a few print jobs, then the same...


It's probably a sensor on the fuser. There are 2 and sometimes they get stuck and just closing the rear door hard will release it. Replace the fuser.

Printing starts..then stops when paper is just appearing.


Replace the exit sensor clipped into the moulding above the fuser. (Very Common)

2004 suburban rear a/c only blows hot air


ase mechanic:
there are separate actuators for the blend doors. one for heat and one for cool. they work opposite and in conjuction with each other, if that makes any sense. ones open, ones close, for each different climate. sounds like the the cold one isn't opening in the rear.

Dome lights intermittently flash on and off in a 1996 Jeep


If it has automatic or a domelight that stays on for a while after you shut the door is on a timer relay and that is probably getting bad. As far as the door ajar message there is a switch in the door jam, look and see if you see it. Take wd40 and try to soak the switch try to get it inside the switch.If its incorporated in the door latch spray back inside the door latch real good. Open and close the door several times and see if it works then.

Error message-Close the back cover


It appears that you have a broken back door have a look on the door to see if there is a broken piece of plastic as when you shut the rear door a tab pushes against a push switch letting the machine know that the door is closed. if you cannot see a broken piece then the switch it faulty try this by push a flat screw driver on the switch and check if the message disappears.

Thanks J

Paper jam. we removed the major portion of it. bit of paper is inside. we can't find out that. display shows 13.20.00. we removed front and back except toner catridge. what we have to do.


Try this linke below.
http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?lang=en&cc=us&taskId=110&prodSeriesId=411171&prodTypeId=18972&prodSeriesId=411171&objectID=c00642524

Or i cut and paste text, but you should view pictures. If you cannot get to it from link. Try typing "Paper jams alternating between front and back door" It should be first link from HP about a 3550.

document.tlSearch.tx.value=unescape("") s.gif s.gif
HP Color LaserJet 3500, 3550, and 3700 Series Printers - Paper Jams Alternating Between Front and Back Door Issue Description Customers may see paper jams error messages with no paper seen in the paper path. The message will alternate between check the front door and the back door. Workaround The release lever engagement tabs on the rear door can be bumped into the in-correct position. The purpose for this tab is to re-engage the fuser release levers as the rear door is closed. When one or both of these are left in the in-correct position the printer goes into a cycle of alternating between a "Jam in the Front Door" message and "Jam in the Rear Door" message. There is no paper present in the paper path when this happens. When a customer gets the "Jam in the Front Door" message and opens the front door, no paper is found. After the customer closes the front door, they get the "Jam in the Rear Door" message. When they open the rear door, find not paper (even pull out the fuser), and close the rear door, they get the "Jam in the Front Door" message. This cycle will continue

Placing both engagement tabs in the "Correct" position solves the problem and allows the print job to continue.for as long as the customer is willing to keep checking.
