  • Page 3: Preface

    These printers are designed for top mount installations and are only available in a non-indexing (continuous print) model. The WPNP-400NI-PIDS-D Digital Web Printers are offered in two different configurations for use with Universal’s PIDS-DIGITAL-CE Programmable Ink Delivery Systems. To provide the necessary web motion and velocity information to the PIDS-DIGITAL Control, one of the installed Web Printers must be equipped with an inductive proximity sensor and a specially modified print drum.

  • Page 5: Printing Dies

    PRINTER MODELS DESIGNED FOR METRIC RIBtype® PRINTING DIES Universal also offers Metric RIBtype® Die Systems for use in countries where metric character sizes are the standard. The Metric dies are thicker and the rib spacing differs slightly from the standard printing dies therefore the two versions are not compatible.

  • Page 6: Quick Start

    3 - The WPNP-400NI-PIDS Printers should be mounted at an angle of 15 to 30 degrees from horizontal as indicated in the Figure below.

  • Page 7: Preparing The Printer For Installation Of The Ink Roll

    PREPARING THE PRINTER FOR INSTALLATION OF THE INK ROLL The WPNP-400NI-PIDS SERIES Non-Porous Web Printers are designed for top mount installation to print on continuous non-porous web materials. To prepare the printer for use, the following steps should be followed.
  • Page 8 QUICK START 4 -Swing the Inking System Locking Assembly to the left (counterclockwise) as shown. FIGURE 7 5 -The Inking System can be removed for off-line installation of the Ink Roll by grasping the Inking System Assembly by the lifting tab and pulling the Inking System out of the machine.

  • Page 9: Preparing The Ink Roll For Installation

    QUICK START 6 -Remove the Knurled Drive Wheel. Note: The Knurled Drive Wheel is installed on the top of the Anilox Roll and is engaged by 3 stainless steel drive pins. FIGURE 11 7 -Remove the Inking System Cover by carefully pulling the Cover straight off the axle.

  • Page 10: Installing The Ink Roll

    QUICK START 2 -Put on the rubber gloves and carefully cut the end of the bag open and remove the Ink Roll. Pre-Inked Rolls are intentionally oversaturated to prolong storage life. There may be a small amount of liquid ink in the bag when it is opened so be careful handling the opened bag after the roll is removed.
  • Page 11 QUICK START 3 -Carefully guide the Cover Assembly onto the Inking System being careful not to scratch the surface of the Anilox roll in the process. FIGURE 18 4 -When the cover assembly is properly positioned against the Inking System Assembly, replace the Knurled Drive Wheel.

  • Page 12: Reinstalling The Inking System On The Printer

    QUICK START REINSTALLING THE INKING SYSTEM ON THE PRINTER 1 -Align the Inking System baseplate with the two slots on the inside of the Printer Side Frames and slide the Inking System into the printer. FIGURE 22 2 - Rotate the Inking System Locking Assembly to the vertical position and lightly tighten the Locking Knob.

  • Page 13: Installing The Printing Dies

    QUICK START INSTALLING THE PRINTING DIES 1-To install Printing Dies on the Print Drum, first mix a solution of water with a small amount of liquid dishwashing detergent to serve as a lubricant. This will make the installation of the die much easier.

  • Page 14: Pre-Inking The Xf Neoprene Ink Roll

    QUICK START PRE-INKING A NEW XF NEOPRENE INK ROLL Note: Dry rolls must be pre-inked before using the PIDS System. Warning: Non-Porous Inks contain flammable solvents. Do not smoke or handle these rolls in the presence of sparks or open flames. Inks will also stain clothing, furniture, carpeting and your hands. Rubber gloves should be worn during the following procedures.

  • Page 15: Basic Principles Of Operation

    The ink never touches any of the pumps component parts so maintenance is limited to replacing the pump tube after approximately 1,000 hours of operation. Universal’s quick disconnect replacement pump tube assembly, facilitates pump tube changes in less than 10 seconds.

  • Page 16: Endcoder Sensory Assembly

    BASIC PRINCIPLES OF OPERATION ENCODER SENSOR FOR DIGITAL MODELS The WPNP-400NI-PIDS-D Digital Printer has been modified to work with Universal’s new PIDS-DIGITAL-CE Programmable Ink Delivery System. The PIDS Control System requires an encoder signal from the printer to track web velocity and to enable programming based on web distance traveled. To eliminate the need to install a separate, friction driven encoder on the moving web, a simple low resolution encoder assembly has been installed on the printer.
  • Page 17 BASIC PRINCIPLES OF OPERATION Note: The nylon tip set screw is only very lightly tightened and should only need to be loosened by turning it approximately 1 revolution in the counter clockwise direction. Do not take the set screw completely out of the plastic isolator bushing or it will be somewhat difficult to re-install.

  • Page 18: Maintenance

    MAINTENANCE CLEANING THE PRINTER Periodically, the inking system should be disassembled and inspected for ink residue and dust contamination. Warning: Most of the ink solvents used for cleaning are flammable liquids. Follow all safety precautions recommended by the manufacturer during this process. 1 -To remove ink contamination from the surface of the machine, moisten a soft cotton cloth with the appropriate ink solvent and rub it across the contaminated area.

  • Page 19: Cleaning The Printing Dies

    MAINTENANCE CLEANING THE PRINTING DIES All inks which are formulated for printing on non-porous surfaces contain a resin binder which bonds the dye or pigment in the ink to the surface of the material being printed. As the ink begins to dry, this binder becomes “tacky” or “sticky”.
