occurs inside the printer that causes various
problem.
Trouble examples:
• Low image density or uneven density due to
recording part condensation.
• Image trouble due to toner moisture absorp-
tion
• Blur image due to condensation on drum
surface.
• Paper discharge problem due to condensa-
tion in paper supply path.
