Loading table
Loading table
You can use the loading table as a working surface to load the substrate roll onto the spindle In order to
position the spindle, use the two slots on the right hand side. Right hub should go inside one of them. Then,
by rotating the table towards the machine, the roll will go to its final position with a small amount of effort.
The user is asked to check that both spindle ends have entered into the final positions.
Spindle latch
The spindle latch prevents the media roll
from slipping from its position when
printing. It is not necessary to close it when
inserting the spindle, it closes
automatically. But the user must lift the small
blue lever in order to release the spindle
and extract the roll of media
Rewinder
The rewinder motor keeps a constant
tension on the input media to prevent skew
problems. There is a motor and a
transmission that gives torque to the
spindle in order to provide the necessary
back tension.
Media sensor
The entry platen has a lever that activates
the media sensor whenever media is
present. When the substrate is inserted into
the entry area, the sensor is activated and the drive roller starts turning to help the loading process. The
media load process has been triggered and the printer will provide instructions through the front panel.
OMAS sensor (substrate advance sensor)
OMAS is located under the third platen slab from
the right, only the top window can be seen:
OMAS is composed of two parts: the sensor and
its optics located under the platen and a PCI
control board on the main electronics box. Both
are connected through a ribbon cable that runs
through the vacuum beam, by the right sideplate
and into the electronics box.
The optical sensor detect the surface of the back
of the substrate as it moves across the platen. The
sensor is able to evaluate the exact movement of
