User mode Summary Setting value Temperature control/produc-tivitySpecial Mode P (Toprevent a curl of thinpaper/ recycle paper)The fixing mode is changed when either ofthe plain/ recycled/ color/ 3-hole paper isselected in the control panel. The produc-tivity is reduced and fixing grade is im-proved.Off (Default) Normal temperature control(Plain paper mode)Medium (Fixing grade is im-proved)Thin paper mode temperaturecontrolHigh (Fixing grade is improved) S-thin paper mode temperaturecontrolSpecial Mode G (Toincrease the fixinggrade for heavy pa-per)The productivity is reduced and fixing gradeis improved.Off (Default) Normal controlOn (Fixing grade is improved) The productivity is reduced by 4sheets or 5 sheets.Special Mode G (Toincrease the produc-tivity during down se-quence)The down sequence time is reduced whenswitching the paper size. The fixing gradeis reduced and productivity is improved.(*3)Off (Default) Temperature difference betweenthe main and sub thermistors tostart the paper feeding: 20 deg COn (Productivity is improved) Temperature difference betweenthe main and sub thermistors tostart the paper feeding: 30 deg CSpecial Mode F (Toreduce the wait timeduring rotation/ colla-tion adjustmentmode)The down sequence time is reduced in thecollation adjustment mode. The fixinggrade is reduced and productivity is im-proved.Image Priority (Default) Temperature difference betweenthe main and sub thermistors tostart the paper feeding: 20 deg CSpeed Priority 1 (Productivity isimproved)Temperature difference betweenthe main and sub thermistors tostart the paper feeding: 40 deg CSpeed Priority 2 (Productivity isimproved more)Temperature difference betweenthe main and sub thermistors tostart the paper feeding: 60 deg C*1. N1 mode: "Normal temperature control" -24 deg C (when the cassette feeding, and the fixing temperature is 100 deg C ormore at the start of warm-up control.)*2. N3 mode: "Normal temperature control" -48 deg C (when the cassette feeding, and the fixing temperature is 100 deg C ormore at the start of warm-up control.)*3. The setting of rotation/collation mode is given priority to over this setting.■ Paper loop amount control before fixingPurpose:• To get a proper image by avoiding a shock when the trailing edge of paper comes out of the registration roles, an appropriatepaper loop is formed between transfer roller and fixing roller.Pressure rollerFixing filmDrumLoop sensor(S6)Transfer rollerRegistrationrollerSensor: OFFSensor: ONStarting conditions:• This control is performed at every paper feeding.Operation:2.
