STEP 1

Before dropping the print heads, ensure that spring hooks are engaged in the slots. The hooks must be facing upward.

WARNING: Extreme force. Install with caution!

STEP 2

Install the Upper bumper bolt assemblies. No not over-tighten hardware. Tighten just enough to hold it in place.

STEP 3

Install the print stations with supplied hardware. Ensure the number on the print station matches the number on the center rotary. Failure to do so will shift the platens out of alignment. Do not fully tighten at this time. They must be snug but loose enough to adjust with bumps of the hand.

STEP 4

Install the 3/16” roll pins to locate the print station. Tap the print station to align holes visually as close as you can. This is a factory setting that ensures your platens are aligned with each other. Tap them in approx. ½” with a hammer. After the pins are seated, fully tighten the print station hardware.

STEP 5

Install the platens onto the print stations. Set the platen in the desired position. To lock it in place, first, tighten the side knob. Then tighten the lower knobs.

STEP 6

Install leveling feet and optional adjustments For uneven floors, install leveling feet & adjust to stabilize the unit. To increase or decrease tension on the print station detent bracket, loosen 3/8” bolts. Raise detent assembly for higher tension and lower assembly for less tension. 

STEP 7: SETTING THE PRESS IN THE "HIGH" POSITION

To set up the overall press height plus 2 inches, first, remove the hardware in the front of the leg assembly. Swivel leg sections downward to align with the rear set of holes. Repeat this step for the remaining three leg assemblies.

STEP 8: BEARING GATE ADJUSTMENT

Bearing gate adjustment. To adjust the locking tightness of the bearing gate assembly, first slightly loosen the 5/16” hardware on the set screw side of the gate. To tighten the gate, turn the set screw clockwise toward the stud holding bearings. Once in the desired position, retighten the 5/16” hardware.

STEP 9

Level the screen clamping heads to the pallets. This one-time setting will work for the vast majority of printing jobs. Future adjustments may be required to accommodate “custom” platens that are much higher than standard.

STEP 10: X/Y MICRO ADJUSTMENTS

Before adjusting registration in the print head you must first loosen the micro lock-down levers (2). To adjust front-to-back use the turnbuckle knobs on the sides of the print head assembly (1). To adjust registration side-to-side, use the long knob on the side of the assembly (4). To get back to “zero” use the pointer on the top of the print head assembly and line up with the center of the hole (3).

STEP 11: TILT/OFF-CONTACT MICRO ADJUSTMENTS

Before adjusting off-contact you must first loosen the off-contact jam knob. Once the desired off-contact is set, retighten the jam knob to hold in place. Before adjusting the tilt micro you must loosen the tilt jam knob. Slowly loosen the tilt locking lever. Once desired tilt is set, retighten the jam knob first and then the locking lever.
