Mfc 640cw has a message unable to clean


This usually means the cartridge itself has developed a problem.
Try removing the cartridge and wiping the print head of the with a clean non-lint rag and alcohol. Then replace the cartridge, sith the printer off if possible. Turn on printer and attempt to have the printer software clean the head again. If negative you may need to replace the cartridge but use an OEM recommended cartridge replacement. After market brands tend to create more issues.

Unable to clean print heads


Unplug the printer from power cord.Press and hold the "menu" button, then plug the device.You'll see on the LCD screen a "machine error" code.If this code is 40,41,49 or 4F the print head is defective.If the error is 48 - defective print head cable or circuit board.If the error is 50 or 51 there is error in Purge unit and printer require service.If the error is 46 the waste ink tank is full.Follow this:
Enter 80, then scroll down with the arrow down (round) key. You'll find an entry listed as purge count. If number is over 6000, enter 2 7 8 3.This will reset the purge count value. Then restart the printer, hopefully without the annoying cannot clean message.

MFC-640CW Switch on error message: "Unable to Init! - User Guide says this is a mechanical fault or jam - not a jam all clear. There is an empty Cyan ink cartridge message as well which is correct. Also...


If there is no jam it is generally a mechanical issue such as...

1. The planetary arm assembly not engaged correctly
2. Ink cartridge/purge switch harness not connected correctly
3. Purge cam switch broken
4. Gear(s) on maintenance unit broken
5. Paper feed motor broken
6. Main PCB defective

I find that if there was a paper jam, and the user pulled the paper out, option 4 is most likely. It is the smallest of cracks but ruins everything!

You will need to contact your local ASC for repair, find it here.

Unable to print when the machine was receiving the fax, phone call rang then it stoped to receive the fax and I got a message "unable to print" I checked everything by user's guide but couldn't fix. Please...


OK ill help you A faxmachine has a buffer on it what it does is fasimilate the data into a text or message that can be printed what happens here is you have fax/printer the buffer for the printer should be on your computer and not be sent until your ready to print (also known as the print que) all print jobs should be saved when a fax comes in but when a fax comes in and you dont have print que software your printjob is lost. But this brand is familiar to me so the software you install for this hardware should have a print que or buffer so you dont have this problem maybe you need the new BROTHER MFC software at the following link http://www.pronto.com/user/search.do?displayQuery=brother%20mfc%2Fsoftware&SEM=true&query=brother%20mfc%2Fsoftware&adid=1196541613-6635448d-0_mes&ref=brother%20mfc%20software&creativeid={creative}&site={placement}&loadingComplete=true

Unable to print 30


the encoder strip is out of position. The strip is the foil which runs paralell to ph direction (and gives the ph the position info).

You have to open the printer and set it back into the ph carrier.

The print head is defective and needs replacement.
BTW the sparepart costs quite a lot of money.
Its better to buy a new mfc!
