Are You Using the Machine in an Environment with Sudden Temperature Changes?
Sudden temperature changes can create condensation, which can result in faded or blurry images and text.
Continuing to use the machine under these conditions may result in paper jams, printing defects, faults, or
other problems. Allow the machine to adjust to the ambient temperature and humidity for at least 2 hours
before use.
Step 5: Checking the Maintenance Status
