4. What Are Its Causes:

Most commonly this problem occurs when a piece of paper is
stuck between the drum and the retaining blade.

The cartridge toner is transferred from the drum to the paper and
the remaining toner is swept to the waste bin using the wiper
blade.

The retaining blade in case of a problem seals the waste bin
preventing any left over toner to escape to the waste bin and that
blots on your printed paper.

Postcard).

After the paper is removed the drum unit will get cleaned by
running it’s self cleaning mechanism.

Look at the back of piece of paper just removed from the drum
unit, it gives a clue as to whether there is any toner powder left in
the printer.

To clean the printer of any traces of leaked toner powder use a lint
free cloth to clean it.
