Engineer TrainingGeneral Mechanic Chassis Structure
In each bottom corner of the chassis are the leveling pads and wheels:
The wheels are used only for moving and positioning the machine in its place.
The leveling pads are the permanent positioning pads of the machine and assist in the final leveling process.

Engineer TrainingPrinting Table
The printing table is used for leading the Media between the Y and Z shafts.
From the Printing table the media goes to the Dryer.
The printing table is adjusted while the machine is in integration stages, and is not possible to readjust during installation.

Engineer TrainingPrinting Table - Construction
The Printing Table is constructed of:
5 Printing Table Bases spread evenly along the Printing Table.
The Bases are connected to corresponding vertical frame beams, and accuratly positioned using the Table Spacers.

Engineer TrainingThe Linear Profile
The Linear Profile consists of the five main elements:
1. The Linear Beam
2. Two Pulleys on each end of the beam
3. Tension Belt
4. Tenacity block, which adjusts the tension of the belt
5. Three Linear Bearings

Engineer TrainingZ AXIS
Z axle is comprised of two shafts:
Z rubber shaft
Teflon pressure shaft
When using the Roll to Roll printing mode, the substrate will be taped to the rubber shaft, which is the end of the media path.
Z Rubber Shaft
Teflon Pressure Shaft
Confidential 35
Engineer TrainingZ AXIS (Cont.)
When using a Roll-to-Sheet printing mode
1. The substrate will flow around the rubber shaft scope to the Teflon pressure shaft, creating an S shape in the substrate flow route.
2. The rubber shaft is then lowered to press the pressure shaft.
3. The pressure created between the rubber shaft and the Teflon pressure shaft, plus the friction between the substrate and the rubber shaft ensures the grip of the substrate and the tension needed for the printing process.
