Explanation
This message displays when a printer option,
Input Tray, or Envelope Feeder, has been
attached while the printer is powered on. To
use the option, the printer must first be
powered off and back on again. Data loss
results if print jobs are active when the printer
is power cycled. If a print job is active, then
remove the option and finish the job. The
printer automatically clears the message
once the option is removed. Once the job is
complete, turn off the printer and attach the
option again.
This message displays when the duplex front
access cover is not installed.
This message displays when the duplex rear
door is open.
