                        General Troubleshooting Solving Print Quality Problems Whenever a Print Quality problem appears, it is advisable to print the  Diagnostic Print to help diagnose the problem. The Diagnostic Print will help  you differentiate between possible printhead errors and other problems such  as incorrect front-panel selection, driver or RIP configuration or mechanical  problems.  The Front Panel is blank 1 See What to do if the Front Panel is blank on page 2-3. The Printer does not Power ON 1 Check that t

                        Troubleshooting  Troubleshooting Media Jams/Printhead Crashes The failure modes "media jam" and "head crash" are grouped together  because in many cases a media jam causes the media to lift up into the  Carriage path and cause a Printhead crash, thus causing many media jam  failures to be reported as head crashes. 1 Did the media jam occur when loading media?  If the client has had media jams, it is common for pieces of media to get  stuck in the media path. Clear the media path. When clearing a
