8.3.2.3.1. Reflex Sensor (Black Mark Sensor)
Working Steps as Flow Chart:
Set the Reflex sensor
current (CV value)
as follows:
In the printer Menu go to Paper Menu\
Paper Type
and select
Black Mark
(PREV or NEXT key, then Enter)
Go to Engine\
Sensor Test
and select
Reflex
Leftmost: VV= currently measured sensor value (Level) At the right: CV= reference value for sensor current
Load your paper into the sensor area
Set
CV (reference value sensor current) in the first instance to approx. 60 % (using
or
key)
Increasing the CV current value (
key) reduces the
sensor measured value (VV level) (
key increases)
Sensor measured value (VV
level
) of
black
mark
as possible more than 45 % ?
Place the black mark of your material in the sensor area
Set the
switching threshold
of the Reflex sensor:
Set the switching threshold to the middle between the paper level and the black mark level:
Save the new switching threshold (level) using the
key
Yes
Yes
No
No
The level (contrast) measured by the sensor is displayed. Press
once again
Measure both sensor levels once again, thereby notice the values for Paper
and
Black mark.
(You need the two level values of your material for the following switching threshold adjustment)
Save the new CV value (
; CV = reference value sensor current)
At the right the switching threshold value is displayed.

Sensor measured value (VV
level
) of
paper
less than
10
%
?
Start the printer in the Service Mode
Reducing the CV current value (
key) increases the
sensor measured value (VV level) (
key decreases
)
Go to Engine\
Sync.Menu\Sync.Sens.Level
Shift the Reflex sensor to the position of the black marks
