Cleaning the Platen Glass and Document Cover

Wipe the Platen Glass (A), the FAU Protective Sheet (white area) (B), and the FAU Lamp (C)
with a clean, soft, lint-free cloth moistened with water. Then wipe with a clean, soft, dry, lint-free
cloth making sure not to leave any residue, especially on the Platen Glass. If you have trouble
getting the scanning area clean, wipe with diluted mild detergent (for dish washing).
Note zThe pattern is printed in black and blue.
When Automatic Print Head Alignment Cannot Be Executed
Correctly
zWhen automatic Print Head alignment cannot be executed correctly,
the message “Auto head align has failed.” is displayed on the LCD.
See“An Error Message is Displayed on the LCD” on page 115.
Caution zBe sure to turn OFF the power and disconnect the power cord before
cleaning the machine.
zDo not use tissue paper, paper towels, or similar materials for cleaning. Paper
tissue powders or fine threads may remain inside the machine and cause
problems such as a blocked Print Head and poor printing results. Use a soft
cloth to avoid scratching the components.
zNever use volatile liquids such as thinners, benzene, acetone, or any other
chemical cleaner to clean the machine; these can damage the machine’s
components.
