brother dcp-L2540dw, scan unable AF  

you can try first to cut a little at the end of harnes(white flat wire connected to scanner and main board)

I try to discharge it for 30 seconds try to unplug the printer and press the power button for 20-30 seconds and power on again. and all goods again

Before you change the whole scanner you better follow this video step by step. And no need to change the adf, because the "unable to scan af" error is not about adf problem. It is about scanner problem. Thank you for watching my video🙂

@@myrj10 oh okay thanks for bringing my attention to it. Okay is the Scanner I need to change and not the complete scanner and ADF. I get that means, if I must do it, I will come back to this video as a guideline. Thank you once again

Maybe the laser scanner isa the problem or the worse is your main pcb or main board is deffective

Thanks, But it is not just scanning but printing is perfect, i.e. the scanner is not moving, only the light in the lamp is dim and eventually after some time the light becomes bright.

try to send your sample print to my fb page... fb page: tonertech express

@@myrj10 Thanks you

@@myrj10 When I do a print job, the print quality is still pretty good. But only blurred when scanning photocopies and scanning pdf.

What do you mean of bad or good? Is it about the brand and model? In my personal opinion and base to my experience this kind of model of brother printer is good for document printing purposes.

ano model ng printet mo po?

pero nag pprint prin po b xa

kc ang scan unable af hnd mo mggmit mag copy at scan pero dpt mkakapagprint k, kc ung scanner ung not working, pero pag nputulan mo n ung harnes nya at gnun prin try mo palitan scanner kpag wala parin dun mo po malaman qng may sira ung board mo pero pagnag pprint prin xa posible n my sira ung board mo n my kilaman sa scanner part pero hnd naaapektuhan an print

@@myrj10 opo nag piprint pa po

@@myrj10 . nputol ko na po sa may flex cable nyu pero ganun parin po ang error. ibig Sabihin po ba ay kailangan na palitan ang board na may connection sa scanner kpag ganito?

Pwdng need mo lng putulan ung harnes or flex n nkaconnect sa board papnta g scanner po. Or need n palitan ung scanner mismo or ang mas mlala po pwdng main board n, pero mas maigi mag start k e check ung flex

main boar mismo po or ung buong scanner lng, magkaiba kc pag sinabi n scanner at ung mainboard..pwd k mag message s fb page q : solidtech express

3 parts can be possible cause of unable to scan af error 1. Scanner flex or harness 2. Laser scanner 3. Main logic board

pag labor lng babayaran mo mga 400 to 600 po un dpende sa tech n gagawa plus ung parts pag af po kc posible palit k ng scanner pag scanner nmn po 500 mga ganyan po

Salamat po

Wala po aq nyn available ngaun, s service center po ninyo drtso
