Description of the Working Steps for the
Reflex Sensor
(Black Mark Sensor):
A)
Start the printer in the Service Mode, compare section 8.3.2.3
(necessary for steps in section D)
.
B)
Select the
Paper Type
Reflex Mark
Please go to [
Paper Type
] in the printer menu structure:
Paper Menu\Paper Type\ select
Black Mark
C)
Shift the
Reflex sensor
to the
position
of your
black marks
See section 8.3.2 Checking and Adjusting the Sensors
D)
Sensor
Current
(
CV
value)
adjusting
Please go to
Sensor Test
and select the subpoint
Reflex
:
Engine\Sensor Test\ select Reflex
The currently measured sensor level (contrast) is displayed.
Press the
key again, after this 2 values are displayed:
Left
VV
=
curr. measured
sensor value (level
)
Right
CV
=
reference value for
sensor current.
CV is
modifiable
(and
has
an
effect
on
the VV
value).
Reflex
Use the
and
keys to set the CV value. Approx. CV value:
Load paper
into the
sensor
.
The sensor measured value (VV
level
) of the
paper
(not black mark)
should count less than 10%.
If the VV level is too high, increase CV (sensor current).
Put a
black mark
into
the
sensor
area.
The sensor measured value (VV
level
) of the black mark should count as
possible more than 45
%.
If the sensor measured value (VV level)
of black
mark is too
low, the CV value should be decreased.
Higher black mark VV
values than 45 % are more advantageous so
long as there is no rising above 10 % of the paper VV level.
Measure both sensor levels once again for Paper
and
Black mark.
(You need the two level values of your material for the following switching threshold adjustment)
Save the new current value (CV) using the
key.
60 %
E)
Sensor Switching Threshold
adjusting
Please go to [
Sync.Sens.Level
] in the printers menu structure:
Engine\Sync.Menu\Sync.Sens.Level
At the right the switching threshold value is displayed.
Use the
and
keys to set the
switching threshold of the sensor to the
middle between the paper level and the
black mark level:
Save the new switching threshold (
key).
