Cause

Possible causes include the following.

• Before the printer is ready, paper was loaded in the rear flat tray.

• The transport unit cover is not installed correctly.

What to Do

• Remove the paper in the rear flat tray and select OK on the printer's touch screen.

   When printing on paperboard, this error occurs if the paper is loaded before the message "Load a sheet of paperboard." is displayed. A different error will occur if the paper is not loaded in the correct position.

• If the transport unit cover is not installed, insert the projections of the right side of the transport unit cover into the printer and push the left side of the transport unit cover until it is closed completely.

  Then, select OK on the printer's touch screen.

  

  

 To cancel printing, remove the paper in the rear flat tray and press the printer's Stop button.
