Hinge and paperfeed

The rear L.H.S hinge has broken . Also when it tries to print, it makes a load "grinding" sound followed by jamming the paper. When I remove the toner, the paper is concertina-ed. Any assistance is appreciated.

    Thanks for your response.. it is appreciated
    What is the fuser's part number; or can the gear be repaired? Is it worth repairing?

  • etcetc914 Aug 25, 2009

    OK I have now replaced the gear and the hinge. The grinding noise is gone. When trying to figure out how to get to it, we removed the sides, PCB etc. etc [I now know that this was unnecessary]. Problem is I now get the "PLS open cover" error message. If I open, and remove the cartridge etc, replace, I still get the error message. I found a manual which told me to go to "maintenance" menu :- MENU,*,2,8,6,4. Unfortunately when I press * I get double beeps, indicating it is not accepting it. Please advise. I suspect once in maintenance mode, I need to enter 8,2 to get the actual error. Your assistance is appreciated

    Seems that your comment was incomplete... Please advise

  • etcetc914 Aug 27, 2009

    I really appreciate your responses!!!. When I enter the code, it tries to go to the menu; ie It double beeps on what it considers to be wrong [eg '*'] and accepts those digits which it considers valid.. the result, I end up in the menu somewhere, not in Maintainence Mode. [even though I enter the digits in less than 2 secs]. I have tried it numerous times, without success. I wonder whether being in Australia, there is different firmware and a different code.

    I finally managed to get it into Maintainence Mode. The machine had the "PLS Open Cover" error message, and whilst that was there, it would not enter the mode. However, if I opened the cover, I could get it into the mode, by entering the code. Of course, the error code as a result of the "82" was "A1" [front cover opened] so, what I did, was to leave it in maintenance mode, and close the cover and entered "82" again and got "Machine Error 72" which is "cannot detect Beam detect signal" ..check scanner motor; check MP tray open sensor. Is this error likely due to the removal of the fuser, or is it from when we incorrectly went around the machine, pulling it apart, trying to figure how to get the fuser out?

    All working!!!!! Thanks!!! The error was caused by a small flat ribbon cable be inserted upside down/back to front.... THANKS HEAPS!!!!!!!!!

You need a new hinge, #LP2403001, and the grinding is because the fuser has a broken gear.

    You have the right info for maint mode and 82..just ignore the beeps while entering the menu * 2 8 6 4, and also check the sensor arm that is mounted on the fuser, and make sure that it enters the side of the printer without rubbing on the frame and when you actuate it manually it is free to move thru the sensor.

    After each try, you have to press the stop key and try again, ignore the beeps and display and just hit the keys in order...Brother assures me you don't have a different code, even after entering the codes give it a few seconds and no matter what the display says if the fax, copy and scan lights are blinking you're in the maint. mode...

    Probably not the fuser, but going around the machine, on the left side there is a lever that opens the laser shutter, sounds like it somehow got out of position, it connects to that front cover to make sure no laser light can come out when the cover is open. The laser is directly over the drum assembly and the lever is at the top left of the door, with the left cover off you can see all the things actuated by the front door.

How do I get rid of paper jam that stays on even if nothing jammed


My guess is that there is a piece of paper somewhere blocking a light beam or in a contact switch.
Try a little air if you can't manually feed a sheet of paper. Use the heaviest bond you have.

Left hinge broke on lexmark pro 905


Not a perfect fix, but this is what I did: There are 2 spring-loaded pistons located on the printer side of the hinge that cause this problem. I think there should be another piece of plastic that holds the top of the printer hinge down on these springs, but when this hinge is gone, the top of the printer is held upward by them. If you use some pliers to gently pull these spring-loaded pistons upward, you can easily pull them out, followed by the springs they cover. Once removing these, the top of the printer lies flat. The top is still unstable, but mine will now feed paper just fine and closes. Hope this helps! WebRepOverall ratingThis site has no rating(not enough votes)

Ricoh SP C410 DN jam from bypass


If you can take off the bypass unit, two screws and a harness, you may be able to check the shaft, bushings and rollers. Sometimes removing jammed paper cause parts to get out of normal position. The grinding noise for example, gears not meshing together correctly. If it worked before the jam, then that is where I would look.

Check document error, no paper jam


It may be a bad hinge on the document feeder. I have seen several times where the left hinge ( when looking at machine from front) does not close all the way. Close the adf and look at the gap between the copier and the adf. The gap should be the same from the front to the back. If the gap is bigger at the rear ( when looking at the left side of the machine) then you need to replace the left hinge. You can also try pushing down on the document feeders' left side as it feeds the paper. if it works while pushing down, then it is the hinge.

Paper gets jammed everytime it copies, it would not go through. There's no paper stuck either. Canon MF6530


I am assuming its jamming in the ADF when you are attempting to make a copy, if so open the top lid of the scanner and check both hinges and make sure they are not broken or cracked. The slightest crack in a hinge will offset the paper path and cause jams. If the hinges look good check for a clear plastic mylar strip under the lid, it will be on the left side. If that plastic strip is missing that will also cause jams.

Brother 8820d MFC auto doc feeder does not work...


You need a new hinge so the cover will sit down properly, or paper will jam anyway, but it sounds like there is still a scrap of paper on one of the sensors inside the ADF, you need to look with a flashlight down thru where the paper goes and also look up thru the slot with the ADF lifted.

Brother MFC-8840d ADF feed problem


Hi, the left hinge is spring loaded to keep the lid open. This applies a lot of pressure on the pivot point of the hinge (steel pin/plastic hinge) that elongates the plastic holes and raises the lid from the scanner. As the paper leaves the scan window, a ramp next to the scan window sends the paper up to the tray, just past that ramp under the lid is a lip that guides the paper to the tray. With the hinge stretched, the lip is too high and catches the end of the paper at the rear only, and jams the paper. If you press on the cover (with the new hinge) and it does not catch then you have installed a bad hinge. Also ensure that the top part of the hinge is on the guide pins under the cover.

8820DN hinge problem


To answer Meyerson's questions:
My symptoms did not include papers jamming in the ADF -- in fact, the ADF didn't work at all due to the broken left hinge.  :(  Also, I don't recall having any unusual problems with the ADF jamming frequently before the hinge broke to the point where the ADF didn't work at all.  
I obtained the replacement ADF left hinge assembly by searching online for a parts dealer.  I believe I ended up ordering the part from Precision Roller. 
I hope this helps,
-Barb
