Background Paper Loading (11xyy)
Background paper loading messages appear when a paper input
source is out of paper, but another paper source is available and
loaded with the correct paper size. The printer stays online in these
situations since it can switch to the other paper source. (“Foreground”
paper loading messages are sent when there are no alternate paper
sources loaded with the same size paper. The printer goes offline and
waits for someone to load paper. Foreground error messages are
listed later in the chapter [41xyy].)
Background paper loading messages are in the format 11xyy. The
following tables list the x and y values for these messages. For
example, 11202 is a background paper loading message indicating to
load the PC tray with letter-size paper.
