    The gantry contains a carriage that sweeps across the table as the gantry moves in steps along the length of the table to print an image on the media. The Arizona T220UV must be operated in accordance with certain environmental and safety requirements noted in this document.

  • Page 13: Product Features

    Introduction The Arizona T220UV prints directly onto rigid media using an original flatbed technology. The printer holds the media stationary on the table while printing is in progress. In addition to the benefits of stationary positioning, the use of UV ink technology on rigid material eliminates finishing processes such as mounting and lamination.

    The second set of principles illustrates some of the residual risks that are inherent in the operation of the Arizona T220UV printer. These are situations or physical aspects of the printer that may present a potential danger to the operator, but would compromise the capabilities of the printer if changed.
  • Page 24 Situations to Avoid Avoid the actions and situations presented in the following table. [11] How NOT to use the Arizona T220UV Avoid these Situations For Your Personal Safety Do not place your hand under the gantry when the printer is powered on. Do not leave any objects on the table printing surface, except for media that you will print on.
  • Page 25 [11] How NOT to use the Arizona T220UV Residual Safety Risks The Arizona T220UV is engineered to minimize machine components and operating procedures that may compromise operator safety. However, in order to maintain some machine operations and functionality, certain compromises are required.

  • Page 52: How To Maintain Print Quality

    How to Maintain Print Quality How to Reduce Banding Introduction Banding can occur in an image for a number of reasons. Typically it occurs due to neighbouring nozzles not firing or nozzles firing with poor directionality. This will occur if debris has been picked up from the media or table by a printhead. If this happens, closely inspect the underside of the carriage with a flashlight and remove any debris with a foam-tipped swab.

  • Page 67: How To Scan Ink Barcodes

    How to Scan Ink Barcodes Introduction Whenever you replace an ink bottle, scan the new bottle’s barcode. The T220UV printer calculates the amount of ink used for each color printed and determines approximately when the volume for a bottle of each color ink is finished. It also retains a record of previous barcodes.

  • Page 68: How To Empty The Waste Bottle

    How to Empty the Waste Bottle Introduction The printer accumulates waste that is made up of ink and accumulated debris. The waste bottle is located on the Home side of the gantry and is accessible by opening the gantry doors. A sensor monitors the waste level in the bottle, and a high level is reported on the control panel.

  • Page 69: How To Change Blot Cloth

    How to Change Blot Cloth Introduction The blot station is located in the left side of the gantry, opposite to the Home position. The blot paper is moved up towards the carriage, by means of a single pneumatic cylinder. The blot paper is supplied on a roll and is advanced using a motor. The motor has an encoder and a variable density optical sensor to determine the diameter of the remaining blot paper, and therefore how far the motor needs to turn to advance the correct amount of paper.
  • Page 70 Installing New blot Cloth Remove the old roll of blot cloth and discard. Remove the old empty cardboard core and save it for use in Step 4. Mount a new roll of blot cloth on the lower supports. Run the cloth up the back and over the top of the blot station.

    How to Use Media Holder Strips Introduction Some media, such as Fome Cor, has a tendency to warp off the table when subjected to heat. This warpage can result in a carriage collision. Media Holder Strips — which are shipped with the printer — help to limit this possibility. Six strips may be required to border the long edges of a sheet of 4'x8' Fome Cor.
  • Page 74 Directions for use: Place the media on the table with a minimum offset of 2"(50mm). Turn on the vacuum. Mask off open vacuum zones with scrap pieces of media less than the height of the media printed on. Push the strips up against the long edges of the media, with the sharp edge protruding into the middle part of the media edge. [23] Sharp edge of the strip against the media.

Part # TA00827 - 1/4"x5'x10' (Actual Size: 1/4" x 61" x 121") Part # TA00826 - 1/4"x4'x8' (Actual Size: 1/4" x 49" x 97") If you think that you need this product, you must buy directly from the manufacturer.
  • Page 76 Tips On How to Use the Underlay Sheet: Use scrap pieces of media to cover any exposed area of the underlay sheet that the carriage will travel over. This prevents the spoilboard sheet from lifting off the table and colliding with the carriage. It may be necessary to bleed the vacuum by opening, or partially opening an additional vacuum zone to reduce dimple artifacts.
