If the devices (Rollers etc.) are misaligned, the paper feed will shift the sheets to one side or the other. If the paper tray is not true when inserted, the paper will be grabbed incorrectly and fed on an angle. I suggest you take apart the roller assembly and lay them out on a table. Look them over for defects. If any bits of paper are left in corners, etc., remove any debris. Wipe down the rubber rollers with rubbing alcohol and air dry. Make certain the rubber parts are NOT slick. Slick rollers will also mess up the paper intake or track movement along the way. I rub all rubber rollers with an very fine abrasive paper to remove the slickness, but I am careful not to damage them. Put the parts back in order. Check the alignment and do not FORCE parts when inserting them. All components should drop in easily and positively.
Hi, When the paper is fed through Automatic Document Feeder
(ADF) it is scanned before copy or fax. The scanner is fixed type and is
located just below the ADF. The
lines are due to dirty scanner mirror. The printer/ scanner design is
based Sheet-Fed Scanner. Open/Lift the Control Panel (scanner top )(by
pulling it up from front - the area from where the paper to scan comes
out). Look out for the horizontal
mirror and use a soft, damp, lint-free cloth to gently clean the
scanner mirror, rollers etc. and enjoy clear scanning and copying! For example see the below picture: -
Inspect
for any tron pieces of paper dirt etc.DONT USE PAPER, CHEMICALS OR ANY ABRASIVE
CLOTH as it may damage the parts.
Hope it helps! Good Luck! Thanks for using Fixya! CreativeTECH
Hello, It can be the problem in sensor flapper on ADF tray ( small nose that is pointing out ). Maybe it doesn't works fine or in the middle of the copy from adf the paper is too far away from the sensor. Also can be the problem of ADF pickup clutch or You are using unappropriate paper type- try with normal A4 80g/m as original to copy from adf.
There are two feeders on this MP730. There is the sheet feeder on top and there is the paper feeder on the back. You can have problems with both.
The sheet feeder on top.
If the problem is things go through somewhat sideways, and if this is the problem, stuff some postit notes between the back grey thing and the feeder tray to eliminate this problem. Add or subtract to the wad to make it right.
If the problem is it does not grip the sheet, what I used to do is to help it through by one sheet at a time, painful. I got frustrated with this so for scanning, I have a Snap Scan 1500, which is faster and better.
The paper feeder.
A small piece of paper left in the paper infeed path can cause a major problem. You cannot have anything in the paper path that will skew the paper, so you must get any little bit of restriction out of there.
As the printer gets older, you will have to produce your own guides to prevent this skewing, as the guides on the printer do not do this well. I use clamps and wooden guides to keep things in line.
I have had this problem before and found that certain types of papers cause this. Can you try some different paper you may have lying around and try that? Post back with the results.
lift document feeder cover and look for paper. if no paper is present there are one or two switch levers that are on the bottom of feeder cover. make sure they can move freely and are not stuck.
If the paper feed roller is dirty, paper is not fed properly because the paper feed roller slips. Cleaning the paper feed roller could resolve the paper feeding problem. Please follow the instructions below to clean the Paper Feed Rollers directly from the unit.Caution: Since the cleaning process wears down the paper feed roller, perform this procedure only when necessary and no more than three (3) times.
Ensure that the printer is powered on and remove any paper from the Auto Sheet Feeder (ASF).
Press the <Menu> button.
Use the right / left cursor button to select [Maintenance/settings], then press <OK>.
Use the right / left cursor button to select [Maintenance], then press <OK>.
Perform the paper feed roller cleaning three times.
Use the up / down cursor button to select [Roller cleaning], then press <OK>.
When prompted to start roller cleaning, use the up / down cursor button to select [Yes], then press <OK>. (The paper feed roller cleaning starts.)
Check if the paper feed roller cleaning procedure resolved the issue.
Load a sheet of letter-sized plain paper in the ASF and open the paper output tray.
Use the up / down cursor button to select [Roller cleaning], then press <OK>.
Use the up / down cursor button to select [Yes], then press the OK button. (Paper will be fed.)
If paper is not fed properly, repeat step 6 up to three times.
The problem is not the sensor, itis the rollers that feed and seperate the paper.
the sensor only tells it there is paper, in the machine. then there is a tire that feeds the paper and another that stops the others from feeding at the same time. If the tire ( on some models it's a pad that looks like it has a rubber or a cork.) is old it looses it's grip and let's the paper slip by. Try cleaning with alcohol, must be replaced eventually.
Are we talking about a paper feed problem from the paper cassette tray or the Auto Document feeder on the top. Either way, check the the paper width guides, or if it is the paper cassette tray, remove it and check the paper pick up roller locking clips.
