7.28.2. Description of Level and Current Adjusting
A) Sensor level adjusting
Please go to [Sync.Sens.Level ] in the printers menu structure.
Place nothing but masking paper in the sensor area and read the contrast
value.
The measured value of the masking paper (level without label) should count
about 10%.
After this place label with masking paper in the sensor area.
The contrast value of masking paper incl. label should count at least twice as
large as the value without label. If this condition is not satisfied, you have to
alter the sensor sensitivity by adjusting the Sync sensor current. (See section B.)
If the values are OK, set the Sync sensor level to about the measured value
(identical to or max. 5% higher than the value of masking paper incl. label).
Save the value.
B) Sensor current adjusting
Start the printer in the Service Mode. (Compare section 7.29.)
Within the Service Mode menu go to Sensor test and select the submenu Gap.
The currently measured contrast value is displayed (as under Sync.Sens.Level).
Press the ENTER key again, after this 2 values are displayed.
The VV value corresponds to the current contrast value.
The CV value serves as reference for the sensor current and is modifiable.
(Consequently modifications have an effect on the VV value.)
If the contrast value (VV) of label incl. masking paper is too low, decrease the
CV value.
The contrast value of the masking paper should count about 10%.
The contrast value of masking paper incl. label should count at least twice as
large as the value without label (therefore more than 20%). Higher contrast
values are more advantageous so long as there is no rising of the masking
paper level.
Finally save the values.
If you modified the values, go to [Sync.Sens.Level ] in the printers menu
structure again and adjust the sensor level. (Follow the directions in section A.)
!
If the adjusting of the Gap Sync sensor failes because the contrast
value of the label material itself is very low, use the panel function
Sync.Sens.Logic to invert the logic. (Black marks can be used as
“inverse gaps” in this way.)
