Error messages

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 re-occurs.
