Paper jam while printing on BROTHER MFC-420CN all-in-one

When I start printing, paper starts feeding, after few seconds I see message on display "paper jammed open back cover and remove it". Without opening back cover, after opening scanning cover and close it, paper comes out from usual slot on the tray without printing. I don't see any jammed paper except the paper supposed to print get stuck at back cover.

Any clue on this.

I appreciate your help

Paper jam


Duplo and Karagatan were early forms of Philippine drama.The Duplo was a poetic debate by trained men and women in the ninth night, which is the last night of the mourning period for the dead. The Karagatan was also a poetic debate like the Duplo, except its participants were amateurs. Both were held in homes and their theme was about a ring that fell into the sea.

My brother 5840CN. lit says unable to print. the manual says to take the jam out - there was no jam. Turn it off, then on. i did that. It still says unable to print, look at troubleshooting page


errr.....No, no it does not. The Manual says that "unable to clean" means one of two things.....
1. The MFC has a mechanical problem.-OR-2. A foreign obstacle, such as a clip or ripped paper, is in the MFC.
but regardless, I don't believe it *IS* a 'cleaning' problem per se.Try resetting the power purge counter.



Press menu > Mono Start > 4x Arrow up after another. All lights will flash.
1. Power clean - Press 7>6>4 >Mono? Start.
2. Power Purge: 7>6 >3 >Mono Start.
Press 9>9 to exit maintenance mode. Run a print quality test print.

Brother MFC-8840D printer w/false paper jam indication.


With my Brother 8840D I have had paper jams that when cleared would not delete from the display nor would the machine operate until I unplugged the machine for around eight hours. I guess it is a sort of reset or reboot.

Display says: unable to clean refer to Maintenance Chapter of users guide (which I cannont locate) Printer is not printing,faxing, nor copying because of this.



acorn gifts --


Here is at least a start to your solution... the Brother site for your printer is here:

http://welcome.solutions.brother.com/bsc/public/us/us/en/doc/manual_index.html?reg=us&type2=-1&prod=mfc420cn_us&c=us&lang=en&flang=all

Which has the download for the actual manual (in PDF) here (you can right-click and "Save Target As" to save to your computer, or open it directly):

http://welcome.solutions.brother.com/BSC/public/files/dlf/doc000219/MFC-210C_UsaEngUsr_B.pdf

Section 11-4 (page 123 of 200) refers to multiple error messages that will halt printing (including "unable to clean"). There are also a few pages following (to section 11-8, page 127 of 200) that give detailed illustrations of how to remove jammed items etc. from the unit.

In the end, the "cause" according to the manual is:

The MFC has a mechanical
problem.
OR
A foreign obstacle, such as a clip
or ripped paper, is in the MFC

... if there is paper jammed, you have a shot at fixing it yourself!

I hope this helps!

MFC-420CN error "Unable to Clean"


Unable to clean comes up as well when the ink absorber is full. It won't let you print or
clean until a fresh absorber is installed, as it could leak all over inside and out. A shop has to do the repair.

Brother mfc-420cn printer envelope jam


If you did not get ALL the jammed sheet out, there is still a small piece of paper in there somewhere, probably covering a sensor or micro switch. Get a torch and look carefully. If you don't find anything you may need to disassemble the printer to find it

Even There are not papers inside the printer, at start I receive the message Paper Jam. In maintenence mode, the message is Error code 36. I tried to unplug few times, same thing. I don't know what to


Two possible causes.

1. There is paper jammed in the purge unit or on the left side of the machine. Move the print head by hand to the centre of travel and look inside at the ends of the head travel path. You might see paper jammed in there.

2. If there is no paper, you will have to take the machine apart and check the encoder strip on top of the head. It should fit into a slot on top of the head. If it is not in the slot, carefully reseat it into the slot, reassemble and test.

There are other more remote causes but those are the two common ones.

Printer message: Unable to Print


5A means that the purge cam stopps abnormally when it is in use. This could be of a broken cam shaft. You have to replace the whole purge unit. This is a service job to do!
