Description

Cleaning the Paper Feed Roller - MP250 / MP270

Solution

If the Paper Feed Roller is dirty or paper powder is attached to it, paper may not be fed properly.
In this case, clean the Paper Feed Roller. Cleaning will wear out the Paper Feed Roller, so perform this only when necessary.
You need to prepare: three sheets of A4 or Letter-sized plain paper
1. Make sure that the power is turned on, and remove any paper from the Rear Tray.
2. Open the Paper Output Tray gently, and open the Output Tray Extension.
3. Clean the Paper Feed Roller.
(1) Press the (Maintenance) button repeatedly until b appears.
(2) Press the Black or Color button.
The Paper Feed Roller will rotate as it is cleaned.
4. Clean the Paper Feed Roller with paper.
(1) Make sure that the Paper Feed Roller has stopped rotating, and load three sheets of A4 or Letter-sized plain paper in the Rear Tray.
(2) Make sure that b appears on the LED, then press the Black or Color button.
The machine starts cleaning. The cleaning will be completed after the paper is ejected.
If the problem is not resolved after cleaning the Paper Feed Roller, contact the service center.
NOTE:After the cleaning is completed, press the Stop / Reset button to return the LED to the copy standby mode.

My makita2012NB was also slip too. I tried to fix it out then I found if I screwed the screw under the rollers tighter it could reduce this problem.

Hey is what you need to figure out what size chain you have,, and these guys can probably provide you with the chain you need
Chain specifications

This seems to be fault in the transport of the paper in the rollers. So if you have used any adhesive sticker printing, it is possible that some glue has got clogged into the rollers. If not there can be some jammed paper in the rollers or the mechanism.
So start this work only if you are mechanically able with the right tools.
Remove the covers to get access to the mechanism . Remove the motor drive assembly , the fitting of the motor to the mechanism. Once this is removed the rollers can be turned manually so that you will be able to feed a paper to see the progress of the movement while studying if there is any obstruction or damage to the paper.
There is a in-detect sensor, usually an opto-coupler , make sure this is not clogged or dirty as this IR detection feeds the signal to the processor for starting the motor drive feed.
Reassemble but make sure the rollers are aligned to be in equal gap to feed the paper without a side pull. Now you must print and see if the fault has changed. If not repeat the above work to confirm the area of obstruction.

Couple of things to check:
1. Are your knives sharp? Dull knives will cut not fast enough to keep up with the rollers.
2. What is the depth of cut? Dewalt's planers cannot plane a board to excessive depths.
3. Are you rollers clean? Dirt, pitch or possibly grease could affect your feed rate.
4. The belt/chain for your rollers engaged or are they slipping? Open up the planer and check for wear or possibly broken belt/chain.
Snipe is usally caused by improper support while exiting the planer. Use outfeed rollers set to the correct height. Also chek that you outfeed bed is aligned with the bed of the planer.
Hope that helps,

Hi,

Try this, without turning off your printer, unplug the power cable from the unit, after you have done that, on your printer, hold the Ok and cancel button to gether and while you are holding it down, plug the power cord back and keep holding the buttons for about 5 sec.

once the unit turns off, use the power button and turn it on. the unit would print and alignment sheet and this should fix the issue

So you need ten sets of a fifty page document for this mornings meeting. It's 8:30AM and your meeting is at 9:00AM. You begin with your project and the copier jams. You clear the jam but it keeps jamming! It's not pulling in the paper. Sure you can call the repair person, but you need the copies now! There's nothing you can do, or is there?

All office equipment that feeds paper has a component inside that pulls the paper out of the paper tray and into the machine. Most are made out of rubber and just like the tires on your car they wear out. When a roller is worn and dirty they will cause paper jams. The purpose of this article is to show you how you can clean or rejuvenate the rollers long enough for you to complete your job and have your repair person come out and fix it properly.

Alternative solutions

When your machine is jamming, first locate where the paper is jamming. Which paper tray? Is it tray 1 or tray 2? Also which size is jamming? On machines that have more than one paper tray you can switch paper trays and then you can skip cleaning the rollers. Make sure when you change cassettes that the copier registers the correct size. The machine will think it is a different size and it will jam. The sensors are set for a specific timing and it will know the difference in length from letter size and legal size. I also would try using the bypass tray or manual feed tray if so equipped. This will get you up and running quicker than cleaning the rollers.

Determining if the rollers are the problem:

If you need the specific tray to be functional we will get busy with the repair.

First make a single copy in the tray that is jamming. By doing this you are determining where the paper is jamming. If it is jamming in the exit for instance, you have another problem. If it is jamming in the center of the machine, again it is a different problem. But if it jams at the cassette or paper tray area the next step is removing the paper tray. Shine your flashlight into the paper feed area and see if there are any pieces of paper torn off inside or something blocking the paper path. Now that you have ruled out a blocked paper path, you can clean the feed roller(s).

Tools Required:

Flashlight, strong cotton towel (so it will not rip off in the machine), WD-40 or Rubber roller rejuvenator.

Note: Never use alcohol to clean rollers. It dries out the tread and the remaining tread will get ripped off and then it still will not feed. Use WD-40 it works great!

Cleaning the rollers:

Shine your flashlight into the paper feed area and locate the rubber rollers that feed the paper in. Grab your towel and saturate it with cleaning fluid. This can be WD-40 or your favorite roller rejuvenator. Start by cleaning the roller and spinning it all the way around not missing any of the surfaces of the roller. Then go over it again with the dry part of the towel. As I said there are many different types. Some have a set of three rollers. One Pre-feed roller, this pushes the paper into the other rollers. One feed roller and one separation roller. Others have a half moon style. These are harder to clean because they have a clutch system that keeps it at home position when not feeding.

WARNING: If you try and turn these to clean them you will damage the clutch mechanism! There are two ways you can clean these types. First you can actuate the clutch by pushing down on the solenoid or release lever. This sometimes can be hard to get to. You can also start the copy process and shut off the machine exactly when the feed roller engages. This takes some patience and practice but it is better than damaging the clutch. Once you get it where you can clean the roller repeat the procedure above.

Some alternatives to replacing feed rollers:

There is a material called feed roller tape. I have used it when I didn't have the right roller in my car stock. It works with some styles mainly half moon styles. Just peel off the adhesive and wrap it around the worn roller surface. They also have some that stretch over the old rollers. I have never used this but I have been told it will get you up and running. On old copiers or printers that you can no longer get parts for you can apply clear silicon on the feed surface and let it dry twenty four hours. It works but I am inclined to use the real thing. You can also use generic rollers manufactured for almost all equipment. I have mixed feeling about these because I have had to go back and change them again later. For the best repair I use genuine OEM feed rollers. They are still inexpensive and they will last you longer and you will have fewer headaches.

Feed Rollers

There are many types of rollers and feed systems. Here are some common feed rollers with their part numbers. Rollers will normally come in a maintenance kit but they may need to be replaced approximately half way through the maintenance kit cycle.

Thanks for using fixya..

feed roller not working or need to replace roller. how long have u had this printer. Try clean the feed roller with a 50 50 solution of water and alcohol. Rollers might have built some tackiness(glue like formed around rollers) the solution will eliminated this, by doing this problem not solved change feed rollers

Researching Your Model. The Rollers are Chain Driven, but this Planer is a V-Belt Drive. Any slippage of Your Belt? Are the Chains Loose?? (there's a Drive Chain on one Side, and a Driven Chain on the Other Ends of the Feed Rollers) Never Hurts to apply a "Light" Coat of Chain Lube to these Parts(Gears & Chains)
DO NOT SAND THE ROLLERS!! Cleaning them with Denatured Alcohol is OK ( I prefer Brake Parts Spray Cleaner Myself)...the Planer Knife Head & the Front & Rear Rollers all work together as a Unit.
What Thickness are You Trying to Remove?? Usually I don't like removing More than 1/32" per pass...
Have you contacted DeWalt Service?
