Envelope Tray Support

If manualfeed in statusdict and the ManualFeed page device parameter are false when the printer receives one of the envelopetray operators listed in

“Table 4-5: Envelopetray Operator Selections” on page 4-12,the printer:

•Sets the PageSize Policy to 0.

•Checks the active source to see if it matches the requested envelope size. If the sizes match, the envelope is fed from the active source.

Note: The active source is the last source selected from the printer operator panel or data stream.

•If the requested size and the size loaded in the active source do not match, the sources are searched in the order defined by the Priority array in the InputAttributes dictionary in the pagedevice dictionary.

•If the requested media size is not found by the previous search, the following search order is used:

—Envelope Feeder

—Multipurpose Feeder

•If the requested size and type are not available from any automatic source, you are prompted to load the requested envelope size and type in the manual feed source.

•If the size is still not available, a configurationerror is issued and the print job is flushed.

If manualfeed or ManualFeed is true, the printer prompts you to load the requested size manually. If no manual feed exists on the printer, a rangecheck error message is generated.

The envelope tray the printer selects when it receives an envelopetray operator is listed in Table 4-5.These operators are equivalent to executing the following PostScript emulation sequence:

<</PageSize [x y] /ImagingBBox null /Policies<</PageSize 0>> >> setpagedevice

where x y are the PageSize in points.
