Switches fusing idling on/off. When on, printing will not start until enough time has elapsed so
the hot roller can reach optimum temperature. This ensures even heat on the hot roller.
Switch on if fusing on the 1st and 2nd copies is incomplete (this may occur if the room is cold.)
You must switch SP1103-1 ON before you set the fusing interval with SP1103-2.

Fusing T Ctrl Fusing Temperature Control
Selects the fusing temperature control method. After changing this setting, be sure the power
the machine off and on again with the power switch to enable the new setting.
[0~1 / 0 / 1]
0: Normal (ON/OFF control). Allows full application from ac power supply to bring the hot
roller up to the target fusing temperature then shuts off. Determines the on time from the present
temperature (detected by the thermistor on the hot roller) and the temperature of 1 cycle before.
1: Phase (hysterisis) control. Sets the upper and lower limits for the temperature; at the lower
temperature the fusing lamp is on and at the higher temperature the fusing lamp is off.
Change this setting to “0” only if the user has excessive electrical noise or interference on the
power supply line. Such interference can cause voltage to drop when power is applied using
the ON/OFF control method.
Interference can be caused by the general poor quality of the power supply lines, or if the
machine is sharing a power supply with other electrical devices such as fluorescent lights. Before
changing this setting, make sure that the machine is connected to a power supply not shared
by other electrical equipment.
Note: Selecting Phase control (“1”) could cause the fusing temperature control board to emit
low pitched noise.

Fusing T Adj. Fusing Temperature Adjustment
Allows adjustment of the hot roller temperature at the center and ends of the roller for the quality
or thickness of the paper. The hot roller in this machine has two fusing lamps: one heats the center
of the roller, and the other heats both ends. Each fusing lamp can be adjusted separately.
Use SP1105-03, 04 to adjust for feeding standard paper from the by-pass tray, and use
SP1105-07, 08 to adjust for feeding thick paper from the by-pass tray.
