Epson EPL-5900L Reference Manual page 26

If you installed the optional Face-up Tray and you want the sheets
to come out face-up, then raise the Face-up Tray instead, and set
the paper path selector down.
Note:
❏ Before printing, make sure that the Paper Size setting in your
printer driver matches the paper you load.
❏ If you want to print on paper heavier than 90g/m² (24 lb) or on
special paper (such as envelopes, labels, transparencies, or thick
paper), see "Printing on Special Media" on page 19.
