Question about Brother MFC 420CN All-In-One InkJet Printer
Hello Mix-it-up (Guru):
I followed your instructions and I list below the error codes:
2:84, 3:A1, 4:84, 5:A1, 6:83, 7:A3, 8:A1, 9:39
Thank you in advance
I guess your machine has a serious problem with the purge unit.
Its indicated thru error 39. (the other ones are quite normal: A! menas Cover open (when replacing carts) and the 8x are related to paper feeder (running without paper/paper jam))
Have a look on the encoder disc which is positioned on one of the big white gear wheels on left hand side. Is it stained or broken/scratched? Do you hear scratching noises when machine is powered up?
Anyway its worth a look. But it could be that the print head has dryed out/clogged though it wasnt cleaned for a while.
If you cant get the error clear the only way to fix the machine is to replace the whole print unit including ph and cart holder (incl. tubes). This is quite simple to do because you can simply unplug the connectors on the main circuit (left hand side red/black cable), loose one screw which is within the metal (position near power inlet, can be seen from above), unfasten the cart holder connector to main board. Unfasten the two white flat cable of the ph.
The whole spare part can be used from a dcp 110c/dcp 115c which you can buy as a 2.hand one at eBay. HAve a look for a dcp with broken scanner glass ;-)
