punload
Unloads proofing media off the drum. The specific proofing media type (carrier,
receiver, or donor) must be specified to protect against having the machine
trying to unload something that's not there.
punload c - unloads the carrier plate off the drum.
punload r - unloads the receiver off the drum.
punload d - unloads the donor plate off the drum.
Note: It is possible that the state parameters of the drum do not reflect the
actual state of the drum because the user may have either altered the
drum's physical state, or changed the drum's parameters with other commands.

See the "Notes" under the "pload" command for an explanation of what happens
(and why) when the drum parameters don't match what's physically on the drum.
