1. If you are using the substrate edge holders, clean them. 2. Clean the sides of the printheads and the sides of the printhead slots. 3. Clean the electrical connections to the printheads. See The Internal Print Server recommends replacing or reseating a printhead on page 406. Dual roll printing issues When printing with the dual roll, the following issues could appear if misalignment occurs: ● Wrinkles ● Ink smears ● Uneven performance between the two rolls ● Telescoping due to Skew convergence Calibrate the dual-roll center support The following steps provide the complete procedure for this topic. 1. Load a single-roll spindle into the printer. TIP: Use a single-roll spindle to calibrate the height of the dual-roll center support accurately. Do not use the dual-roll spindle, as it is heavier and it may not be level along its length. 2. Place the dual-roll center support under the center of the spindle. ENWW Dual roll printing issues 373
