Brother Print Unable 50 Error

The printer have its own initialization but seem to fail to complete initialization process. Check and clear the carriage jam, open check for motor failure in the carriage system.

Details of this error code are.
50,51,52,57,5A,5B,5C
5D,5E The machine does not work due to a paper jam or some sensor problem. Clear the paper jam. (Please refer to "FAQs & Troubleshooting" for information on the Paper Feeding.) If the problem still continues after clearing the paper jam, please contact Brother Customer Service from "Contact Us".

try to clean the printer from the inside. clean the cartridges and all of the connections that you can find. I wouldn't stat opening the printer, as it may cause further damage which will forfeit your warranty

on my DCP 130C display appear an errore message "imp. stamp 50". This is an error message in italian language that indicate impossible to print, error 50.
Please, have you some suggestion to resolve this problem?
Thansk in advance

Brother DCP-130C is not printing and is refering me to the manual which is useless. It also says "Unit unable 43" .
Any help great! Cheers

i got a brother printer dcp135 ,but it got a error (print unable 51)
how i settle it???
thx...

check the paper jam clear cover at the back site of printer:

When taking it out you can see the wave formed clear plastic which is on top of the cover.
try to stroke with your finger alongside. this can be the reason for the paper jamming.

- pull out the AC plug
- put back the AC plug while holding down the "menu" button and keep holding it (15 sec)
- now you are entering the MAINTENANCE mode and "error 46" pops up in the display
- select 8 by using the arrow buttons ,push OK and select 0 and push OK
- 00:00 00:01 OK (the display is showing this message)
- now push the MONO button 25 times until you see PURGE: xxxxx
- Select 2, push ok, select 7,push ok,select 8,push ok, select 3,push ok
- the purge counter indicates now: purge: 00000
- switch off the printer ,switch it on
- ready to print
