    Arizona 250 GT Ink Introduction The Arizona 250 GT uses UV-curable inks including Cyan, Magenta, Yellow, and Black. Due to the UV curing technology, the ink dries immediately and the printed material may be handled or cut directly after printing. The ink part numbers, which are necessary for ordering more ink, are provided in the table below.
  • Page 85 Arizona 250 GT Ink Ink temperature control is achieved by pumping a coolant fluid through the ink reservoir block and printheads. An internal thermostat on each printhead and one on the reservoir block provides temperature feedback. The condition of the printheads is maintained by periodic cleaning at the maintenance station on the gantry.
  • Page 86 UV Flush solution Ink Filters The Arizona 250 GT ink system is protected from contaminants in the ink by means of four ink filters. These are easily accessed and can be replaced by the end-user when they become blocked with debris. The expected average lifetime for a filter is approximately 6 months or 11 bags of ink (22 liters).
  • Page 87 Arizona 250 GT Ink Note: A loss of pigment when printing a nozzle check indicates that a filter is clogged and must be replaced. How to Store and Handle UV Ink To ensure good quality images and to extend the life of printheads in the Arizona 250 GT printer, it is important to have good UV ink management procedures.

This section provides detailed information about what is required for proper printer maintenance. While Océ Display Graphics Systems furnishes guidelines for periodic maintenance, the optimum maintenance schedule evolves from careful observation of your printer over a period of use.
  • Page 99 Maintenance Guidelines Operator Maintenance Schedule The Arizona 250 GT printer requires regular maintenance. Periodic cleaning should be scheduled for some components during the week. A few minutes spent cleaning ensures the highest quality prints. Several areas require maintenance to ensure the highest print quality, and the printer design gives you easy access to all these areas.

  • Page 100: Maintenance Procedures

    Printhead Maintenance Maintenance Procedures Printhead Maintenance Introduction The Maintenance Station is located below the carriage. Printhead Maintenance takes place while the carriage is parked. The station is covered by a sliding door that has an open grid in the center that allows any waste ink to drip down through the station and into the waste tray.
  • Page 101 Printhead Maintenance Before you begin Make sure the carriage is in the parked position. The carriage and gantry automatically return to this position after an image is printed. Do not move the carriage or gantry from this position as this will make it impossible to perform an ink purge.
  • Page 102 Printhead Maintenance Illustration [49] [49] Maintenance Station Switches How To Perform Maintenance Slide the cover out from under the carriage to reveal the maintenance station. Press and release switch 1 to initiate a purge. The carriage will lower to its purge height (4mm above the table surface).
  • Page 103 Printhead Maintenance Note: In the next step, start with the left printhead and work to the right as this limits the possibility that drops of ink will fall onto the coiled hose. Also, do not push up too hard on the printhead as you may dislodge it and this will require a service call to fix.
  • Page 104 Printhead Maintenance Maintenance for Select Printheads On the top of the carriage there are 4 hand-turnable ink valves. If you have performed a printhead maintenance and find that one or more printheads require additional maintenance, turn off the valves of all the other colors. Perform all of the steps for printhead maintenance again, but only on the affected printheads.

  • Page 105: Remove Ink From The Table

    Remove Ink From the Table Remove Ink From the Table Introduction How often you need to perform these procedures will vary, depending on printer usage and work habits. Remove Ink from Table Clean ink from the table whenever necessary. Once UV ink is cured, the best method for removing it from the table is to use the provided scraper (it is also possible to achieve good results with a razor blade that is set into a handle/holder).

  • Page 106: Empty The Ink Waste Tray

    Empty the Ink Waste Tray Empty the Ink Waste Tray Introduction The waste tray is located below the Maintenance Station. It accumulates ink that has dripped from the printheads or ink waste that results from a purge when performing Printhead Maintenance or Swabbing the Printheads. The ink drops onto a sloped drain plate at the base of the Maintenance Station and drains from there into the waste tray.
  • Page 107 Empty the Ink Waste Tray How to Empty the Waste Tray Put a cloth or paper towel in place on the floor to catch any drips while the tray is emptied. Place a suitable empty container that holds at least 1 liter under the waste tray drain. [53] [53] Waste Tray Valve Turn the valve on the waste tray until it starts to drain the waste material.

    Swab Printheads Swab Printheads Introduction To ensure optimal print quality, it is important to periodically clean the printheads with a swab to remove any excess ink or any debris that was not removed by Printhead Maintenance. When to do At the end of each week, clean the printhead nozzle plates using the swabbing procedure.
  • Page 109 Swab Printheads Attention: Never "scrub" the printhead with a swab as this will drag debris into other nozzles. Always slowly move the swab across the printhead with the swab at an angle and not perpendicular to the printhead. Never use Isopropyl alcohol to clean the printheads. Do not allow swabs to be contaminated with any dust or dirt prior to use.
  • Page 110 Swab Printheads Run a Nozzle Check print or an image test print and verify that all nozzles are firing properly. Note: If the problem persists, you can swab multiple times. Use a new clean side of the swab each time (this means a maximum of two swipes per swab). It is possible that as many as ten swipes can be required.

    Clean Carriage Underside Clean Carriage Underside Introduction To maintain optimal print quality, it is important to periodically clean the underside of the carriage to remove any excess ink. If the buildup of ink is excessive, it can be transferred to media and thus reduce print quality. When to do At the end of each week, or as needed, clean any ink that has accumulated on the underside of the carriage.
