2. Diagnostic Information
Diagnostic Approach
This printer can be serviced without being connected to a host computer.
This printer displays both operator correctable errors and service
errors on the front (operator) panel. In addition, there are two tests
available from the base machine and the optional 2000 sheet paper
deck that allow you to b ypass the controller card. You can use these
basic engine function tests to eliminate potential software problems.
See “Diagnostic Aids” on page 3-1.
The diagnostic information in this chapter should lead you to the failing part. Before you replace an entire assembly, determine if just the
defective part is available in the parts catalog. Some diagnostic procedures indicate the parts catalog location of the part to be replaced
by including the assembly number and reference number in parenthesis. Use the error code tables, symptom table, service checks
and the diagnostic aids chapter to determine the symptom and
repair the failure. After you complete the repair, perform the appropriate tests to verify the repair.
Start
Initial Check
Before you start troubleshooting, check the following:
Installation Environment
•
The power supply line voltage is plus or min us 10% of the rated
line voltage.
•
The printer is securely installed on a level surface in a well-ventilated place.
Diagnostic Information 2-1
4040
•
The room temperature is between 10 and 32.5 ° C, 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.
EP Cartridges
If blank spots appear on an output image, there is a chance that the
toner is not evenly mix ed. Rock the toner cartridge and then make a
print to see if the toner has evenly mixed.
Other
If a packaged EP cartridge is opened soon after being moved from a
cold room to a warm room, condensation will appear inside the cartridge; this can cause various image defects. In such cases, be sure
to instruct the customer that it is necessary to leave the cartridge
sealed for one to two hours at room temperature to allow it to acclimatize.
