The optional duplexer allows you to print on both sides of the page on
any size media at 300x300 dpi. However, printing duplex via the cas-
sette at 600x600, or 1200x1200 dpi resolutions may require addi-
tional memory. (See the memory tables in chapter 3, the “How Much
Memory Do You Need?” section, of the
Operations
manual for each
resolution/media size memory requirement.
Caution:
Due to the curved path of the duplexer only paper between
17 and 28 lbs should be used. Envelopes, transparencies, and labels
should not be used when duplexing.
