I am using this printer from more than 3 years I have never faced any techinal problem till now.
I have printed more than 5, 000 pages on this printer ( both coloured and black & white ) this is a duplex printer which the best part , hassle free both side printing bye to old school open and load and boom print lolz wifi is also great touch screen printer no touch problem yet working fine , scanner is very good HD Scanning full bright colors and great pixels.
The only problem I faced with this printer is that if u are looking to print some heavy papers like super professional thick papers then this printer is not for you guys as it will create problem for the printer to load these paper this is the only con I can found in this printer I used it commercially still using it Brother printers are amazing .
