How many prints on the metre? Try checking the corona assemblies, try running 11 x 17-test pattern 1. See if there is any pattern to the fault, or is it completely random.

243000 copys taken till now. the problem exist only first 15 to 20 copys. after that it will solve

This looks like a paper moisture problem to me. Open a fresh ream of paper and try that to test for it. I assume it is as humid in India as it is in Iowa, USA. If the paper sits awhile, this can happen. 15 sheets down into the stack, the paper is probably drier,,, till is sits for awhile and soaks up some more humidity...

You have problem with humidity.
1. Your paper may have moisture.
2. Your transfer and separation corona assemblies may have moisture. Check for any sign of oxidation. Clean if necessary.
Is there any dehumidifier in that machine? Turn it on if you find.

there are no dehumidifiers in imageRunners

Customer can purchase one to put in room/ or store paper in a large plastic bin w/ a cover-
I had a customer shrink wrap their unused paper out of the ream-

u should load more paper than u need in Decks/or Cassettes - I preach that until blue in face.
Makes no sense to even load paper sizes that are rarely used during the week

it maybe a grounded transfer

Run it duplex. If it is a moisture problem the second side should be fine(fuser removes moisture on first pass).Tech 101.... Also if you run until its ok then stop and start new job,is it light again? Rewire the coronas to start

For me normally i will change the primary transfer corona wire and it should be done as in my country doesnt effect for the humidity problem. i got similar problem with this that the vertical line fading does running and after changed the drum unit everything fine.
