  • With EPL-5900, the standard paper supply consists of the cassette-like universal paper tray (250 sheets) and manual feed tray (one sheet). EPL-5900L is equipped with a 150-sheet paper feed tray.
  • EPL-5900 supports an optional 500-sheet lower cassette (A4).
  • Toner life: 3,000 pages with the pre-installed Imaging Cartridge and 6,000 sheets with a replaced Imaging Cartridge. Neither the pre-installed Imaging Cartridge nor replaced Imaging Cartridge is interchangeable with that for EPL-5800 or EPL-5800L series.
  • The Photoconductor Unit is common to EPL-5900 Series and EPL-5800 Series.
  • The face down tray attachment is available as an option.

Note:    This attachment is not a general option. It is supplied on user request or tender request. The capacity depends on user environment. This attachment is not described in manuals or catalogs.
