Plain paper and limited thick stock up to 28 lb bond (105 g/m²) can be auto duplexed if
the optional duplexer is installed. For heavier weights, manual duplexing is recom-
mended. 12"x18" (304.8x457.2 mm) and 13"x18" (330.2x457.2 mm) media cannot be
auto duplexed.
In general, if you’re having output problems with your duplexer, try the following:
1 Ensure that you are using correct media.
Do not duplex envelopes, glossy stock, labels, transfer media, or transparencies.
2 Ensure that you have not mixed media types in your media cassette.
3 Ensure that your document has more than one page.
4 Go into the printer’s control panel and ensure that duplex is an available
option.
5 In the printer driver (Paper tab, Duplex option), choose On (flipped as in a
loose-leaf notebook) or Tumble (flipped as on a clipboard).
6 Remove media that is still jammed.
Caution: Always open the duplexer’s rear cover before opening the printer’s or
duplexer’s top cover. Forced opening of the top cover first may damage the unit.
Check for media stuck in the paper guides in the duplexer’s top cover, rear cover,
and lower rear assembly.
7 If you removed jammed media from near the OPC belt, reset the OPC belt’s
locking levers.
8 Ensure that all of the covers are closed.
Caution: Always open the duplexer’s rear cover before opening the printer’s or
duplexer’s top cover. Forced opening of the top cover first may damage the unit.
Open and then close the covers to confirm that they are securely closed.
9 Ensure that the duplexer’s lower rear assembly is firmly seated in the printer.
