The time is alsoextended when smeared image control mode 2 or paper wrinkle/curl prevention mode isspecified.Special mode Fixing mode Extension time- Heavy paper 1 2 sec.- Heavy paper 2 2 sec.- Envelope 1 5 sec.- Postcard 25 sec.Smearedimage controlmode 2Setting: 1 - 15 sec.Setting: 2 - 30 sec.Setting: 3 - 60 sec.Paper wrinkle/curl preventionmodeOFF Plain paper L 5 sec.*1Paper wrinkle/curlprevention 1/2Plain paper,Plain paper L20 sec.*1: At 30 deg C in temperature and 80% in humidityNOTE:• Smeared image control mode 2Set by User Mode > Special Mode c.
