Print engine error codes

Generally, the top line of the two-line front panel display indicates the printer's
status, such as Ready, Printing, Busy, or Stopped. The bottom line
indicates the function of the three buttons located immediately below the LCD.
The front panel also displays error codes when it encounters certain system
failures. These error codes are discussed in the next topic. When an error code
first occurs, cycle power on the printer to see if the error reoccurs.
The following table list the engine failure codes that may be displayed on the
printer's front panel during normal printer operation.
