Start
Initial Check
Before you start troubleshooting, check the following:
Installation Environment
•
The power supply line voltage is plus or minus 10% of the rated
line voltage.
•
The machine is securely installed on a level surface in a well-
ventilated place.
•
The room temperature is between 10 and 32°C (50 and 90°F)
and the relative humidity between 20 and 80%.
•
Avoid sites generating ammonia gas, high temperature or high
humidity (near water faucets, kettles, humidifiers), cold spaces,
near open flames, and dusty areas.
•
Avoid sites exposed to direct sunlight.
Print Paper Checks
•
Be sure the recommended paper for this printer is being used.
•
Check the paper for dampness. Make a trial print with paper
from a newly opened package, and check the result.
Other
If you move the finisher into a warm room from a cold location such
as a warehouse, various problems can occur due to condensation if
it is immediately unpacked. If condensation should appear, either
wipe the relevant parts with a dry cloth, or leave the finisher power
on for 10 to 20 minutes.
