The
scanner unit consists of:
· Truss with mounting clamps for the Scanner plate
· The tightening sequence
of the mounting bolts is required to fit the scanner plate’s components into
the optical axis correctly!
The scanner plate contains the mountings for the units
· Truss,
with Locating surfaces
· Focus
unit’s dovetail mounting
· Focus unit’s dovetail fixing
· X-Y-stage
unit’s dovetail mounting
· X-Y-stage unit’s dovetail fixing
· Preview
unit’s horseshoe mounting
· ND
filter unit mounting
· X-Y-stage
unit bumper with mounting
To define the plane of the scanner unit in relation to
the turret unit and to ensure the straightness of the optical axis, locating
surfaces are used.

unit’s horseshoe mounting
The
horseshoe mounting contains two fixing pins to define the position and a
threaded hole for the mounting bolt.

X-Y-stage unit
The
X-Y-stage unit can be removed or mounted only, if the entire base plate with
scanner plate is removed!

Focus unit’s dovetail mounting
The dovetail mounting ensures the proper position of the X-Y-stage unit
and the focus unit in relation to each other.
The mounting of the focus
unit and the mounting of the X-Y-stage unit are realized with dovetails; these
are hold by dovetail fixing clamps.
- Focus unit: Rotate
the 2.5 hex key
wrench clockwise to open (loosen) the dovetail clamp.
- X-Y-stage unit: Rotate the 2.5 hex key wrench
counterclockwise to open (loosen) the dovetail clamp.
The
horseshoe is the mounting part of the preview unit, and contains the mountings
of following components:
- Objective and
camera holder with fitting plate
- Preview
mirror mounting (can not be removed!)
- Barcode illumination
The entire preview unit is situated on the edge of the
scanner plate, parallel to the magazine unit.
The position is fixed with two fixing pins and hold by
the mounting bolt. To allow an easy remove of the optics, the horseshoe is
divided into a camera half and a mounting half.

Remove the preview unit
· Remove
the mounting bolts and separate the camera half from the mounting half.
Mount the preview unit
· Fit
the fixing pins of the mounting half with the position fixing holes of the camera
half and drive in the half’s mounting bolts.

Preview
objective and camera holder
The
preview objective and camera holder allows the adjustment of the preview camera
rotation angle in a limited range.
· To
adjust the distance of the objective in relation to the horseshoe, a fitting
plate is used.
To adjust the camera rotation angle:
- Hold the camera on the rear and loosen the position fixing bolt a
little bit until the camera together with the objective becomes barely
rotate-able. Check the tightness of the objective to the camera!
- By loosening one of the “Camera angle” bolts and tightening
carefully the opposite bolt, the rotation angle will be modified.
- If the correct camera rotation angle is found, tighten the
“Position fixing” bolt by pushing the camera to the holder; further
information can be found in the chapter “Adjust the
preview camera rotation angle”.
With the locating
surface, the correct distance between turret plate and scanner plate is
defined; the turret plate is mounted by the use of clamps
and contains the mountings and fixings for the following main units:
·
EPI-fluorescent
illumination unit
