The tray that the developer unit slides into may not be moving all the way up to the drum on the side that is blank.
Maybe a screw or something blocking its smooth travel towards the drum as you push in the developer unit release lever.
push in and out the developer release lever to observe its motion with the developer unit removed.

Hey, that's a really good idea. Where have I seen that before ...? =^..^=

It looked like he/she didn't quite understand your post, about this and thought a more
drawn out description might help her/him see the light you cast on the possible solution,
so I took it upon myself to give it a go.

Thanks copydocinc and Black cat for the ideas. Actually this video tells what happened. Your idea works. Sorry video not able to attach.Ok.

. I checked the movement of developing unit and found fine.I checked this action without drum unit present. So i thought initially the problem will be something else. Also as I stated before that when I press the drum unit strongly the image is clear, so in my mind i was thinking about the biasing problem only.thats why I stick onto one point couldnt solve the issue.

What happened actually the front side of the sliding developing unit release lever got little bent and it is not co-inciding with drum unit ( it should go inside of the "front cover cleaning " of the drum unit.

Also thanks to everyone who supported me. :-)

Actually when black cat said about this one I checked the movement of the developing unit, and found good. unfortunately i checked this solution after removing the drum unit. so that I can see the action. But later I found the front side of the developing release lever got little bent and becoz of that the drum unit obstructing the developing unit to engage properly.
Anyway thanks for the solutions. Thanks everybody again. Cheers...will see u guys with another problem....

Re: Partial Image is not clear on Taskalfa221

this is one of the problems many people have encountered on these machines but its caused by a small plate on the dev unit sliding plate which when you lock the dev unit its suppose to push the dev unit towards the drum. check on that plate that touches the drum unit ground plate, it could be touching on the drum unit.its on the front side of the machine behind the waste toner box.your dev unit is not close enough to the drum and not connecting properly to dev bias connector.

hope this is the solution
