Troubleshooting Jet Drop-Out ColorSpan Legacy Solvent and UV-Cure Printers 1
Document Scope This document describes jet drop-out that occurs during active printing and methods for isolating the cause of the drop-out. Overview There are three general causes of jet drop-out.
Vacuum Vacuum is used to suspend the small quantity of ink within the printhead on-head reservoir. (See Tech Note 2749, Vacuum/Pressure System Guide for Operators, for additional information on the vacuum system.) Both too much vacuum and too little vacuum can lead to jet dropout. Diagnosing a Vacuum Issue While the printer is printing and jet drop-out is observed, pause the printer and send the carriage to the capping station (solvent printers) or parking station (UV printers).
