Automatic paper-type sensor
The HP automatic paper-type sensor detects the paper in your printer, and then
selects optimal print settings for that media. The result is fewer mouse clicks to start
printing, and automatic optimal print quality on plain, photo, brochure and other high-
quality papers. The sensor also checks the paper width to ensure it matches the size
selected in the printer software. If the widths are different, the printer warns you so
that you do not waste a sheet of paper.
When the auto paper-type sensor is engaged, the printer uses a red optical sensor
light to scan the first page of a document and determine the best paper-type setting
and check paper width. If the paper width is different from the printer software, the
printer warns you and gives you the opportunity to stop printing. If the width matches,
the printer determines the paper-type setting and the page is printed.

Caution Do not place the printer in direct sunlight. Direct sunlight can
interfere with the auto paper-type sensor.
