Axis X-axis Y-axis Z-axis T-axis W-axis M-axis S-axis Table 2-1 FB7500 Axes Functions Function Printing table movement. Bridge cross-print movement that determines the cross-print resolution. Bridge up and down movement. Up/down movement along the Z-axis is required to adjust the distance between the substrate and the print heads for different substrate thicknesses. Loading substrate onto the printing table. Substrate alignment when loading it onto the printing table. Opening/closing the UV lamp external shutters on the front side. Opening/closing the UV lamp external shutters on the rear side. Printing Bridge The FB7500 printing bridge contains the print heads and all of the peripheral systems supporting them, such as secondary ink tanks with taps, vacuum knife, water reservoir, two overflow boards, switch ink valves, UV lamp housing, UV lamp external shutter, UV fumes extraction duct, power distribution boards, PIC and ORCA electronic boards, purge manifold, water manifold, ink and water tubing, electrical cables, bridge lifting pistons, Y-axis, Z-axis, Maxis, and S-axis motion systems. The bridge is covered with the upper and lower hoods. The printing bridge components and their location are shown in Figure 2-4 to Figure 2-7. 10 HP Scitex FB7500 Advanced Printer Guide
