Aside from a misadjusted 'darkness' control, improper voltages, dirty corona
wires, and worn drum, don't overlook the trivial: your paper may be incorrect

I am a former copier tech. that worked on Konica copiers. To get good results
from your copier, a periodical maintenance should be perform on the copier,
every so many copies or once a year, depending on which event occurs first.
During a PM, the optics, corona wires, drum gets cleaned. The Fixing unit gets
cleaned, and serviced. The Developer gets replaced. And adjustments are
performed, if needed only.
The developer transports the toner to the charged area of the drum and
developer gets weak over time. Developer is made up of iron filings.
