Light areas in printouts from laser printer panasonic kxp-..

Hi!

Could someone please explain why after cleaning of the drum in the laser
printer Panasonic KXP-6500 there are now several rows of the text (in the
bottom part of the sheet of paper, and partly also in the middle) printed with
much less amount of toner (the text is very light in these places)?
I tried to clean the drum (with a special liquid to clean drums) 2 more times
to get rid of the problem, to no avail. However, before the first cleaning
(due to some black spots) it seemed that there wasn't such a problem with
light printing. Toner is loaded in full so it's not because of toner ending.
