Loud ratchet noise when turning printer on....I think paper in feeder

I am unable to use printer. I have cleared the front, back and paper tray of any "jams", but I think that tiny little pieces of torn-off paper is is the rollers and preventing the machine to work. Of course, 1 year and 3 should I somehow unscrew the plate in the front and see if I can get at it to solve the problem? I do a lot of printing, faxing, scanning...but my work software requires parallel print.....thus the MFC, which has capabilities for both USB and parallel. The Brother jams a lot, I remove the paper, and go on. It might be that I have the paper setting wrong, or it just could be using or reusing paper for draft copies.

    I'm not as far along. Once the printer starts up as it's receiving a job, it will make a grinding noise. It pulls the paper through but jams. What is the problem and how can I fix it?

The part number for the heater roller has changed. it is LM2706001 and as of today it is 22.04. That is why the lady could not pull it up. Had to get transfered directly to parts to find it.

The problem is a broken gear. Part number LJ7416001.
It is in the fuser assembly.
To remove:
Looking at the back of the laser, you will see a flat "platform" going across under flipdown access door. There is a screw in the middle of it. Remove it with a philips screwdriver, and slide the plastic platform out.
pull the door downward to about a 45 degree angle or so, and it will slide off a pair of flat retaining pins. One on each side. These are part of a molded plastic piece. Each piece is held on by two screws. Remove those. The plastic pieces come out:
NOTE: there is a hook on the bottom of each piece that hooks into the metal frame. The hook faces down. DON"T break them off. The plastic needs to move up and out. After removing the two pieces of plastic, you will see a metal enclosure on the right side of the printer, with two phone jacks in it. It is held on with 2 screws. Remove them and swing it out of the way. Behind it is another large philips screw. Remove that. On the other end of the fuser is another screw. This one has a slot in it, and a small cross slot. Use a flatblade screwdriver to remove this screw.
After it is removed, you can slide the fuser back. you will notice that there is a small multiple wire cable on the right. Unplug it.
On the left are two leads that feed the heater. they plug into a connector that is in the left side of the printer. Pull the connector out, and you will see on the top or bottom side of the connector, a clip that holds these together. Press it toward the connector and pull it apart.

Remove the fuser unit.
With the red roller downward, you should be looking at the top of the fuser. The white power leads run along it. At each end of the fuser, there is a philips screw. One of them will be kind of hidden by the white wires. Remove those two screws. DO NOT REMOVE the screws holding the small pieces of metal under the wires.
After than turn the fuser around so you are looking at the paper rollers and the blue levers.
Just to the left of the left lever, and up about 1/2 inch, you will see a plastic "latch" that hooks over a ledge. CAREFULLY pry it back, and press up on the top of the fuser. On the other end of the fuser, there is a small black gear. There is a latch underneath it facing to the left. Gently pry it to the right, and if both latches are free, the top of the fuser will lift up.
The broken roller should be obvious. Before you move the roller, look carefully at the two black sleeves on the end of the roller. They have to be replaced exactly in the same place. You will need to remove the screw holding the heating element in place in order to lift the heater roller enough to get the old gear pieces out and install the new gear. At this time, the gear is 2.89 from brother. The heater roller might be slightly bent on the end (mine was). It can be straightened. I tried to order another one LJ7415001 but was told that was not a valid part number. The person I was talking to finally agreed to transfer me to extenion 2190 (877-276-8437) when she could not find the number, and hung up on me.

The gear will slide over the heater roller. NOTE:
There are two black sleeves on the end of the rollers. They each have a pair of "ears" on the opposite sides. These will need to be oriented so they are horizontally, and make sure they are in thier slots. BE SURE to screw the screw into the heater connection.

This same procedure can be used to replace the heater element, just don't touch the new heater.

Once done, you can re-hook the top of the fuser, install the screws and reverse the entire operation. A small dab of high temp grease on the gear may keep it operating smoothly. Since the gears are a weak spot, and are cheap, order two so you will have a spare.

    If it making a load ratchet noise and not working and you don't have 2 year warrantly like us then


    Best bet pretty common too that it is the fuser drive gear busted (noise would come from rear)


    Or the rego roller drive 'front left' if facing it noise whould come from


    But experence being a brother agent, tells me you need a new fuser assembly fitted approx Aus$250-350


    Have also rarely seen it caused by poor refil toner cart unable to turn, take out and power up to remove possibility of cart fault

Loud noise coming from the paper feeder

Most noises that are a clicking type is caused by the tray not in position correctly, make sure the tray is free to lift and or is pushed in all the way. Broken fuser gear can also cause issue. Double check to see if the drum is turning correctly (to check, turn off the unit and turn on without the tray in. If clicking occurs can't be the tray.

My MFC8460N Brother won't print. It makes this

Gears on the tray is broken, or the gears that lift the tray. (thus the clicking noise). And the no paper is due to the actuators underneath not being activated because of the non lift.

The printer is constantly sending a message- 'paper jam'

HP Officejet 7200, 7300, and 7400 Series - 'Paper Jam: Clear jam, and then press Enter' Message Displays on the Control Panel Display
During printing, the paper becomes stuck in the all-in-one and the error message 'Paper Jam: Clear jam, and then press Enter' displays on the control panel display.
Use the following instructions to clear a paper jam from the product:
Step one: Check for and remove any loose paper from the In tray
Do not try to remove jammed paper from the In tray. First remove any loose paper from the In tray to avoid worsening the jam.
CAUTION: Always try to remove jammed paper from the back of the printer first to avoid mechanical damage.
Step two: Clear the jam from the back of the printer
Follow these instructions to clear jammed paper from the back of the product. If the product is equipped with a two-sided printing accessory, skip to that section.
Remove the rear access door to clear the paper jam

1. Remove the rear access door by pressing the buttons on the side of the door and pulling it toward you.

2. Gently pull the jammed paper out of the rollers.
WARNING: If the paper tears while removing it from the rollers, check the rollers and wheels for torn pieces of paper that might remain inside the product. If all the pieces of paper are not removed from the product, more paper jams might occur.
3. Replace the rear access door. Gently push the door into the all-in-one until it snaps firmly into place.

Remove the two-sided printing accessory to clear the paper jam

1. Remove the two-sided printing accessory by pressing in the buttons on the sides and then pulling the accessory toward you.

Step four: Verify that the print carriage can move freely
Follow these steps to try to move the print carriage.
CAUTION: Do not force the print carriage to move if it is out of plain view or feels stuck. Forcing it may damage the printer.

Step six: Service the printer
If you have completed all the steps listed above and are still experiencing a problem, service the product.

Feed paper is pulled into the right side of printer (facing Printer) and jams. Cleaning no help.Canon Pixma MP600.

I had the same problem,tried and failed with all maintenance tasks including cleaning all rubber rollers and belts,manually turning the rollers and belt,only succeeded in forcing out some small paper debris,but still jamming.Googled for answers,even looking at a technician service manual post by,none have provide a tried and succeeded answer,even the paid answers by experts were suggesting the rollers needed to be replaced due to wear and tear,but we are only light duty user,it is unlikely.Next thing you know $3 a question,20 questions later,you are out $60 and still end up with a broken printer . I finally used thick heavy photo papers to test print as they are unlikely to rip and tear when jammed,the first time it made a very loud and very loud grinding noise,I cancelled the printing immediately and slowly and firmly pulled the photo paper out from the front ejecting compartment,a small piece of what looked like a spiral bounded calender type paper came out with the pulling.Tried again with photo paper for printing,this time it made the same loud noise again,stopped print immediately,thought I f-cked up,while carefully and firmly pulling the photo paper ,a small piece of Styrofoam came out.After that every printing test for front paper loader and the front bottom cassette loader work flawlessly with plain paper.I realized that the front loading feeder tray iwas the entrance culprit of these small shits that got inside without any body's knowing.Taped the front feeder tray close,use only the bottom cassette feeder as it is completely enclosed,nothing will get in there.Because a lot of people put things on top of the printer cover when not in use,**** got in there accidentally and stupidly.Hope this will help, saved myself a lot of money and time in setting up new printer to the local and wireless network,I am not a techno guy.Try at your own risk,I had nothing to lose,thought I had to buy a new printer,now the printer is working like new,smooth,quite and fast.

My Brother HL 5250DN printer has started making a loud clicking sound when it tries to feed paper for printing. It then stops and the paper light starts flashing.

Clear the jammed paper as follows.
Observe Cautions signs in printer.
Always remove all paper from the paper tray and straighten the stack when you add new paper. This helps prevent multiple sheets of paper from feeding through the printer at one time and prevents paper jams.
1. Press the cover release button and then open the front cover.
2. Slowly take out the drum unit and toner cartridge assembly. The jammed paper will be pulled out with the drum unit and toner cartridge assembly.
3. Pull the paper tray completely out of the printer.
4. Close the front cover.
5. Pull the jammed paper up and out of the printer.
6. Open the front cover again.
7. Open the back cover.
8. Pull the tabs at the left and right hand sides toward you to open the fuser cover (1).
9. Using both hands, gently pull the jammed paper out of the fuser unit.
10. Close the back cover.
11. Pull the duplex tray completely out of the printer.
12. Pull the the jammed paper out of the printer or the duplex tray. Put the duplex tray back in the printer.
13. Push down the blue lock lever and take the toner cartridge out of the drum unit. Clear the jammed paper if there is any inside the drum unit.
14. Put the toner cartridge back into the drum unit until you hear it lock into place. If you put the cartridge in properly, the blue lock lever will lift automatically.
15. Put the drum unit and toner cartridge assembly back in the printer.
16. Put the paper tray firmly back in the printer.
17. Close the front cover.
18. Make sure that the Paper LED is now off and the printer is ready.
After clearing paper jam if noise persist printer may need a Repair Tech and parts replacement for broken or wore parts.

Make sure you have selected the multi purpose feeder (front of the printer) in the driver, not the Manual Feeder.

Hope this helps....
Explanation of the paper jam message

A 241.09 Paper Jam message indicates that the printer thinks a sheet of paper has jammed at the front of the printer. The jammed sheet of paper is most likely to be found in one of the paper trays or under the toner cartridge.
NOTE: If you select Show areas on the operator panel, you can view one or more images to help you locate and clear the jam.

Clearing the jam
To resolve the paper jam message, you must first clear the entire paper path. To access the jam area, you will need to open one or more of the paper trays. Follow the steps in the table below to help you locate and clear the jam.
Step Action Image 1 Open the printer paper tray (tray 1), and remove any jammed media you find there. pattlnk_10222007_1922-enus28872_24109paperjam1_t64x_en_us.gif 2 Open the front cover and remove the toner cartridge. Examine the area inside the printer and remove any jammed media you find there. pattlnk_10242007_159-enus28872_24109paperjam5_t64x_en_us.gif 3 If you have a duplex option installed, also remove the duplex access tray and remove any jammed media you find there. pattlnk_10302007_1559-enus28860_24x17paperjamduplex_t64x_en_us.gif 4 If you were printing from an optional paper tray, such as tray 2 or tray 3, open any optional trays, starting at the top, and remove any jammed media. Pull the print media either up or down. If it does not pull easily one way, try the other way pattlnk_10222007_1957-enus28872_24109paperjam3_t64x_en_us.gif 5 If you are printing from an optional 2000-sheet feeder, open the front door. Press the elevator button (A) to lower the tray. Remove any partially fed media from the feeder.
NOTE: Make sure the stack of print media is straight and pushed all of the way into the feeder. Incorrectly loaded paper is the most common cause of paper jams from a 2000-sheet feeder option.
For a larger image, click here. 6 Finally, reinstall all of the paper trays and press the pattlnk_10222007_2117-select_button.jpg button to try printing again.
NOTE: You may receive a different paper jam message informing you that another sheet of paper is jammed elsewhere in the printer. If this occurs, the error code will indicate the location. Click here for a diagram showing the error code locations. The paper path will vary, depending on the paper source and number of paper feed options installed.
Remove any jammed sheets of paper you find and try printing again.
