When the time to replace the transfer roller is reached, the message 

TRANS.ROLLER END

 appears. Printing can continue even after this mes-

sage appears; however, since the print quality is reduced, the transfer roller 
should be replaced immediately.
When replacing the transfer roller, also replace the ozone filter. A new ozone 
filter is included with the new transfer roller.
