The optional duplexing unit allows you to print on both sides of a
sheet of paper using either manual feed or automatic feed from a
paper cassette. Additional memory is required for duplexing at 600
dpi resolution on legal-size media. The following chart represents the
minimum amount of memory needed to print various paper sizes at
300 or 600 dpi resolution. In most cases, the minimum amount of
memory does not allow the printer to run at rated speed. The
amounts shown assume the Page Recovery function (Administration/
Engine/Page Recovery) is turned on.
A Phillips screwdriver is needed for this procedure. To install the
