Clean the Original Scanning Area Screen Prompt

To "Settings/Registration Table."
You can use the Display Original Scanning Cleaning Area mode to prompt you to clean the scanning area when the machine detects streaks or stains. If the feeder is not clean, the machine will scan and print dust and grime on the output. The Clean the Original Scanning Area Prompt appears when originals are placed in the feeder. For instructions on cleaning the feeder's scanning area, see "Routine Maintenance" in Basic Operation Guide.
Depending on the region, the optional product is required to use this function. For information on the optional product, see "Optional Products Required for Each Function."
