4.4.01 Preliminary Checks
Is the product being operated under the proper ambient conditions?
Does the paper being used meet the specifications for this product?
Have the consumables been replaced as recommended?
Have the consumables been installed properly?
Are Okidata consumables being used?
Is the LED Head Drive Time correctly set?
Check the contacts and connections of the power supply board. If good contact is not
made at
all connections and ground points, false diagnosis will occur.
Examine the basic check points as directed in the Solutions
manual.
Gather as much information on the problem from the customer as possible.
Perform inspections in conditions which resemble those in which the problem occurred.
4.4.02 Tips For Preventing Image Problems
Do not let anything touch the surface of the image drum.
NEVER expose the image drum to direct sunlight.
Do not touch the fuser unit. It is heated during operation. Oil from your skin may cause
uneven fusing temperature.
Do not expose the image drum to light for more than 5 minutes.
