Question about Brother MFC-8640D Printer

1 Answer

Scanner not working

I discovered the problem when trying to scan from the document feeder today. It would pull the paper in, but stop once the paper got to the scan head. Next I tried to scan from the flatbed and I noted the scan head did not seem to be moving... same deal with copying. I finally received a "Machine Error A6" code and a message to call Brother support... they were of no help and said to take it to a service center... so is anyone familiar with what might be my issue? My deduction is the scanner bar/head is not moving.

    Yeah I bought a replacement.  It is the 8840D, which is the same model except it has a different colored doc feeder and double the memory.  Fingers crossed this one lasts me longer. 

    In any regards, how does one go about getting the PCB for this thing?  I called a service center to inquire about their "bench fee" and he looked up the scanner part.  It was in the $200-300 range if memory serves me right.  He said that was a common problem with Brother, parts cost make repairing them prohibitive.  Aside from the fact that there are quality issues to begin with... I like the machine though.

    Funny to hear about you calling in and them instructing you to essentially call yourself or a competitor.  I was reading an article the other day about the lack of customer service anymore.... this would be a supporting point for that.

    Thanks for your input.

    That sounds like it might be worth trying... any ideas on where someone could get the main PCB for this device? Any advice on getting to it? A repair manual would be great if anyone has such an animal.

I work at a brother authorized repair center, the bad thing is that there is no specified A6 error, in any manual and when you call brother and tell them that you are calling from an Authorized repair center and that you need help with an A6 they*gasp* tell you to call an authorized repair center. Sorry about the rant.

The A6 is a general error relating to the scandeck on most MFC machines(9700/8440/8640) etc...

try changing the main PCB, it can be a little costly, however it generally doesn't take long, that is the general cause of the error. However, sometimes that doesn't work, so to save yourself a little time and money, just go buy another printer.

Will not scan from glass but feeder will?


Using your scanner program such as PaperPort, you really have to pay attention on where the document/photo is located for scanning.


Steps
1. Click on Start, Programs, Paperport
2. Right above the Word "SCAN", you will have several options on;
a. Document or Photo
b. Flatbed or Feeder
3. Once step 2b has been selected, the M20i will scan your document per your instructions.

Note:#1
If you place your document on Flatbed but your selection on your screen says "Feeder" where do you think the scanner will look for your document? The answer is --> Feeder!!!

Note #2
Make sure that you click Accept,& DONE, other wise M20i will just sit and wait for your next command.

I hope this resolves the confusion between GLASS and FEEDER scanning.

ADF paper jam, when there is none


If you are receiving an Error Code 103 or a Paper Jam error, but there are no pages in the ADF (Automatic Document Feeder), follow the steps below:
  1. Close the scanning application (such as PaperPort)
  2. Turn off the scanner and the computer
  3. If you have a combination ADF with a Flatbed scanner, unplug the ADF cable from the base of the scanner
  4. Plug the ADF cable back in
  5. Turn on the scanner power
  6. Turn on the computer
  7. Try scanning again
For a Paper Jam or Error Code 103, make sure that the ADF cable in the rear is connected to the scanner base. Check the flatbed to make sure that it is clear. A page incorrectly placed on the flatbed may interfere with a page feeding through the ADF.

If your scanner stops scanning due to a paper jam in the Automatic Document Feeder (ADF), a warning dialog box appears after a few moments.

To clear a paper jam:
  1. Open the Automatic Document Feeder cover.
  2. Remove the jammed paper and close the cover.
If you are receiving a paper jam error, or if the scanner is running continuously, check to make sure the paper sensor arm is not stuck down.
  1. Open the Automatic Document Feeder cover.
  2. Look for the small black plastic arm
  3. When you press on this arm, it should move freely up and down
  4. If the arm is stuck down, please contact Technical Support for troubleshooting options
  5. Close the ADF cover.

E9 code


E9 code means there is a paper jam.

Clearing Paper Jams
If your scanner stops scanning due to a paper jam in the Automatic
Document Feeder, a warning dialog box opens after a few
moments.
To clear a paper jam:
1. Press the ADF cover release on the top-left of the scanner
body to open the Automatic Document Feeder cover.
2. Remove the jammed paper and close the cover.
To reduce the number of paper jams, smooth and straighten the
paper before scanning and adjust the guides to the paper size.

This should help. Please let me know if it does. Thank you, Binary Bob

Scanner not working


A6 is a scan failure detection.

This sounds to me like the motor running the scanner is not working. However, there are three or four causes of this error. The home position sensor, the motor, the CCD, the main board and the engine board.

You should be able to find the sensor that detects the scanner lid. Fool it with a piece of tape or a finger. Look at the scanner after pressing copy to see what is happening.
You could open up the scanner and check the movement to make sure it's smoth, but this is a lot of work. The best option is to pick up a used scanner from a Brother service centre. Install it and see if it solves your problem. Of course, you wouldn't be able to return it if it did not solve the fault. This is why Brother recommended you take it to a service centre, the troubleshooting is very in-depth for a fault of this nature.

Scanning does not stops


please check all sensor arms in the document feeder. The sensor arm in the middle just below the separation pad is called 'paper end sensor'. If this sensor arm is blocked or broken the scanner don't stop the feeder.
Another possibility is a driver error.
