Cause:

If the toner contains small clumps, they disintegrate in the development unit, producing streaks.

This problem may occur if the machine is left unattended for a long period or the toner bottle is kept out of its moisture-proof bag for a long period.

Solution:

  1. Print 350 full-page, solid-fill A3 or DLT sheets.
