Allows you to reset the PWM of the ID sensor
LED to avoid a service call error after clearing
NVRAM or replacing the NVRAM.
[0 ~ 255 / 100 / 1 step]
The PWM data is stored by executing SP-3001-2.
Performs the ID sensor initial setting. ID sensor
output for the bare drum (V
automatically to 4.0 ±0.2 V.
Press "Execute" to start. Perform this setting after
replacing or cleaning the ID sensor, replacing the
drum, or clearing NVRAM.
Displays the current V
grayscale control.
[0V ~ 5.00V]
If the ID sensor does not detect the ID pattern,
is displayed and an SC code is generated.
If the ID sensor does not detect the bare area of
the drum,
is displayed and an SC code is generated.
Toner and carbon clinging to the hot roller strippers
can cause poor print quality. To prevent this, toner
and carbon are dislodged from the hot roller
strippers in two ways: 1) jogging the fusing/feed-out
motor 3 times after every print job. 2) freely rotating
the hot roller for 12 s. For details, see Section
"6.6.2 Hot Roller Stripper Cleaning". Also see SP
5959.
Prescribes the number of times the fusing/exit
motor is switched off/on in order to dislodge toner
clinging to the hot roller strippers.
[0 ~ 60 / 12 / 1 ]
Raising this setting can increase wear on the hot
roller and cleaning roller and shorten the service life
of the hot roller.
Prescribes the number of pages to print before the
fusing/feed-out motor is jogged (switched off and
on rapidly) to dislodge toner and carbon from the
hot roller strippers.
[0 ~ 1000 / 0 / 1]
Normally the motor is jogged once (switched off
and on rapidly) after every print job that exceeds 15
pages.
