I am ekta pawar , I want to share you my experience about HP DeskJet 640C.i buyed it from snapdeal on 07-06-2010.After 8 months I facec the problem of jam.
I cannot print a simple job over two pages to completion.It Jams and cannot feed paper correctly.i have sent it twice for servicing in the service center but it came with the same problem.I have jumped through every hoop conceivable and nothing ressembling a decent output over two pages even worst, That I have to restart all over my computer again to ensure that I could print again.It takes 1 minutes for black & white print! If you print in colour it take 2 to 3 minutes.This is alert to all Do not waste your money.Thanks
