Environmental Checks
Verify that the printer is operating within standard environmental specifications:
• The temperature is 10 to 35° C (50 to 95° F).
• Relative humidity is 10 to 85%.
If the printer is operating in an environment that is outside of these conditions,
print quality can suffer. You can move the printer to another location, or correct
the environment that the printer operates in.
