Canon IR 3570 Printing very light

[princepriyu]

my photocopier Canon IR 3570 is printing very light from the upper side nearly till the center of page,
if i print via computer or photocopy or MAILBOX
i have tried changing DRUM, TONNER POWDER, but no use
i have attached SCANNED COPY of a demo print page

if i try to print a scan & print a photocopy it is even worse than the print quality given by computer

Please Note :- to print SOME good quality i have to always darken it while every print manually on the screen of

Inspect & Reseat transfer roller and confirm correct pressure.
Check the front and rear transfer arms for proper positioning.
When positioned properly, each end of the transfer roller should "spring back" after being pressed. If the roller is not positioned correctly, check that the springs on each end are in place.

Try cleaning toner from the slit glass located on the scanner laser assembly.

Another possible cause of light or faded copies is when the developing assembly is not receiving correct cam pressure.

there was some tonner on the glass of scanner as you explained,
i have cleaned it by doing so print quality has gained little but not perfect.

but how does it gets accumulated over there, and what should be done to avoid it in future ???

please can you guide me setting transfer roller (where is its location i am confused is it the fuser unit ??)

Transfer method = by transfer roller= transfers images from the drum to paper=bias voltage applied to the transfer roller causes the toner to move from the drum to
paper.

It leaks from the hopper assembly if you take the hopper out and clean it you can stick sellotape around the join to prevent toner leak in the future.

You have mentioned you change the drum but not to clean the scanning area, making to try clean the mirror glass slit inside the scanner there is possible the mirror glass covered by the dust.....i have encountered before that problem...

i have cleaned the laser unit glass,
i have also removed the glass and wiped and cleaned the CCd Scanner neatly

but friends the quality did not improve
i have attached images that are taken after cleaning

also the images that are printed (PC Print or Photocopy) from IR3570 is having vertical Lines, How are these created
