Page 13 2． 3 Status: After install the printhead, print the nozzle status. Observe the printhead order and position, and the condition of the printhead. “Status”shortcut on the main interface： Click “Status” to print the following diagram： Turn off the feather function when doing the alignment！ 2.4 HVert: Printhead angle alignment.
Page 14 first straight line reference, then check second straight line. Both line should be connected, if not, the printhead holder need to be adjusted. Please check the following cases: Case 1：Both line in same vertical position; Second Pass First Pass No need to adjust！ Case 2：Printheads offset to left side：...
Page 15 Note: Tighten the four screws at the printhead holder when finish adjustment and before print the Hvert test diagram. Keep adjust until the first pass and second pass face each other. When vertical adjustment done, normally horizontal alignment well, printhead's horizontal alignment is not aligned, then have to do the adjustment. The following diagram shows how to adjust the horizontal position.
Page 16 While the adjustment is not good, we need to adjust by software. Just enter “Setting\Option”, showed as the below picture: To Right To Left Choose “Unicolor” Adjust K1-K2 Factory setting： 180DPImode：；C：1-2= ；M：1-2= ；Y：1-2= -9 ；Lc：1-2=-9 ；Lm：1-2=-9 K：1-2= Please click the “Save Parameters” after inputing values, then print the adjusting picture of the same color again.
Page 17 Note: K is the reference. At the “0” point, other color should overlapped on K. If not, look for the rectangle which is overlapped, and input the corresponding value into the “Head Adjustment”. The following example use C (to right) to demonstrate: As the picture shown above, the rectangle of C and K are overlapped well at “-1”, at “0”...
