Chapter 1. Getting Started Printer Components Operator Panel The five buttons appearing across the top of the operator panel control printer operations, such as powering the printer and fluid system on and off, opening and closing the eyelid, and cleaning the printhead. The seven lights appearing across the bottom of the panel report operating conditions such as low fluid levels, errors, and the detection of tach and cue signals.
Chapter 1. Getting Started Printer Components Fluid Compartment Note: Use only Kodak Versamark-approved inks. The fluid compartment, contains the ink and replenisher bottles. Replenisher maintains the relative concentration of ink to water. A light on the operator panel comes on when a fluid bottle or external ink container is depleted and needs to be replaced.
Chapter 1. Getting Started Supporting the Printhead Supporting the Printhead The printhead support must hold the printhead steady to protect it from vibration. The support must also hold the printhead within 0.0 to 1.00 inch (2.54 cm) of the substrate, and support the weight of the printhead and umbilical.
Chapter 1. Getting Started Supporting the Printhead The printhead mount stand consists of an extendable arm, mounted on a steel base with casters. The printhead mount stand provides a stable, mobile printhead support (Figure 1.3). Figure 1.3 Printhead mount stand 1 - 6...
Chapter 1. Getting Started Setting Up the Printhead Setting Up the Printhead Proper printhead setup helps to ensure print quality. Multiple printer configurations and angle printing require certain restrictions or considerations when positioning the printhead. Determining Substrate Movement The printhead has a series of dot indentations appearing on the sides of the printhead cover to indicate the direction of normal substrate movement.
Chapter 1. Getting Started Setting Up the Printhead Printing at 90° The printhead starts up, prints, and shuts down from all angular positions between 6 ft (1.83 m) above and 2 ft (0.61 m) below the base plate of the printer.
Chapter 1. Getting Started Setting Up the Printhead You can further verify accurate printhead positioning by ensuring that the distance between substrates is equal to or greater than the cue distance for the most downstream printhead. In multiple printer configurations, all printers to be used for the job must be selected to print and must be configured according to the system software being used.
Chapter 1. Getting Started Determining Cue Distance and Cue Delay Determining Cue Distance and Cue Delay The cue sensor and tach encoder, each mounted on the document transport, are required for proper printing. The information provided by these devices determines when printing occurs.
Chapter 1. Getting Started Determining Cue Distance and Cue Delay Cue Sensor The cue sensor detects the substrate as it passes under the print array. Two cue values, cue distance and cue delay, must be entered in the system software for printing to occur at the desired position within the image area.
Chapter 1. Getting Started Determining Cue Distance and Cue Delay Cue Delay Cue delay is the distance from the leading edge of the piece (or substrate) to the start of the image (Figure 1.9). The value entered for cue delay is based on the image position required for the job. Figure 1.9 Cue distance and cue delay Substrate direction...
Chapter 1. Getting Started Document and Image Lengths Document and Image Lengths Two other parameters are required by the printer: document length and image length. These two parameters are illustrated in Figure 1.10. Figure 1.10 Document parameters Image Length Leading Edge Piece Cue Delay...
Page 26
Chapter 1. Getting Started Document and Image Lengths The maximum document length is dependent upon horizontal resolution and is the same as those shown for cue distance and cue delay in Table 1.1. Enter the values for document length (sometimes called substrate length) and image length at job setup using the procedures described in your systems software Operator’s Guide.

Chapter 3. Troubleshooting Identifying Printing Problems Irregular Gaps Irregular gaps appearing in the test pattern at powerup usually indicate that air is trapped within the printhead. Irregular gaps can also be caused by a concentration of ink. Perform a printhead clean to remove the air bubbles or ink concentration. (See Chapter 4 for printhead cleaning procedures.) Irregular gaps may also appear when the voltage or phase setting is incorrect;...
Chapter 3. Troubleshooting Identifying Printing Problems Miscellaneous Problems The following printing problems are caused by several different sources. Smears Smears appear on test prints as areas of smudged ink. Print smears are caused by outside sources, such as substrate stacking, wet print, and paper guide malfunctions. Check for these types of problems after the substrate has passed under the printhead.
