Hardware description
The product provides the following features:
● Prints at 1200 dots-per-inch (dpi).
● The flatbed scanner scans at 600 pixels-per-inch (ppi) with 24-bits per pixel (bpp) and has
an automatic document feeder (ADF) that holds up to 50 pages.
● The formatter and the line interface unit (LIU) provide Group-3-compatible faxing
capabilities.
● The product prints 20 pages per minute (ppm) on letter-size paper or 19 ppm on A4.
● The main input tray has a 250-sheet capacity for continuous, multiple-page printing.
● The priority input tray accommodates manual feeding of up to ten sheets.
● Both trays are center-justified for all supported paper sizes.
● The output bin holds up to 125 sheets.
● The product has a very fast first-page-out, at less than eight seconds.
● When the fuser has reached operational temperature, the first-copy-out speed is 12
seconds when using the flatbed scanner and less than 18 seconds when using the ADF.
