Initial Actions
NOTE: To aid in troubleshooting image quality issues, use media from an unopened ream

fused with blank or partial images.
•
Check the error logs,
GP 2

defect.
•
Do not use cleaning pages
(TP
22) to evaluate image quality.
•
If possible, run a customer print job using default settings.
•
Use approved media within specifications,
there are no loose particles which can cause ink blisters where ink adheres to the debris,
not the media. If necessary, turn over the media in the tray.
•
Check the operating environment is within specifications,
•
Make sure the machine is positioned to allow adequate airflow at all vents. Refer to
Installation Space Requirements.
•
Make sure the interior of the machine is clean. Refer to
dure.
•
Check that the paper tray guides are set to the correct paper size.

Check that the fixed paper tray guides are set to the correct paper size,

•
Check the document guides on the DADH.
•
Check that the image adjustment and print mode settings are correct for the image being
printed/copied.
•
Check the settings for the media size and type are correct for each tray.
NOTE: Always load A4 or 8.5 x 11 inch media as appropriate to your market region in
Tray 4 before printing internal test prints. Failure to do this may result in the test prints
printing the wrong size / location on the media and giving false results.
•
If possible, check that the customer is not attempting to copy poor quality originals. If the
original is too damaged to successfully feed through the DADH, suggest scanning directly
from the document glass.
