Scan Warm-up Time
If the machine is used in a room where the temperature is low, the machine may not be able to
scan originals clearly. Selecting [Long] for this setting may improve the scanning quality.
Default: [Normal]
• Normal
Select this if the room temperature is about 19 °C (66.2 °F) or higher.
• Long
Select this if the room temperature is about 18 °C (64.4 °F) or lower. This prolongs the warm-
up time for the machine's scanning unit by about 10 seconds.
Low Humidity Mode
If the machine is used in a room where humidity level is low, black lines of a few millimeters thick
may appear on printouts with 75-millimeter spaces in between. Selecting [On] for this setting may
prevent these lines from appearing (wait for about one day until this setting becomes effective).
Note that when this setting is enabled, the machine automatically performs self-maintenance in
every 10 minutes.
Default: [Off]
• On
• Off
Image Density
