Paper Jam Messages (LaserJet 5Si/5SiMx
only) (42xyy)
Foreground paper loading messages are sent when one of the paper
input sources is out of paper and there is no other input source
available and loaded with the correct paper size. When this occurs,
the printer goes offline until someone loads paper.
The messages are in the format 42xyy, where x is the number of
jammed pages that need to be cleared and yy is the location of the
jam that was detected. The following table lists the y values for these
messages. For example, 42203 indicates 2 pages are jammed in the
fuser output.
