Fusing Idling
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
1103*
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.

[0 to 1 / 0 / 1]
1104*
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
SM
0 = Off, 1 = On
[0 to 60 / 30 / 1 sec.]
Sets the machine to fusing idling only for 30
sec. for every job (when the original is set on
the ARDF, when the ARDF cover is opened,
etc.) and the fusing unit has reached the
reload temperature (optimum temperature for
operation).
[0 to 30 / 0 / 1 sec.]
0: No idling done before a job.
