Image-Quality Problems Overview Image-quality defects can be attributed to the following: ■ system hardware components or communication ■ consumables ■ media ■ internal or external software applications ■ environmental conditions To successfully troubleshoot print/copy-quality problems, as many variables as possible must be eliminated. Note To aid in troubleshooting image-quality issues, generate prints using the information pages embedded in the system software on paper from the approved media list. (See the media specifications in the section "Tray and Media Specifications" on page 1-16 for media that has been tested and approved for use in this system.) The paper should be from an unopened ream that has been acclimated to room temperature. If the print-quality defect is still present when printing on approved media from an unopened ream of paper other conditions need to be researched. The following steps should be performed for diagnosing print-quality problems: 1. Verify the media being used and the environment for the system are within specification. 2. Isolate the print-quality defect to either a malfunction of the DADF/scanner (IIT) or a malfunction of the print engine (IOT), and once identified: ■ Troubleshoot the DADF/Scanner ■ Troubleshoot the print engine When analyzing a print-quality defect from a print engine malfunction, determine if the defect occurs: ■ in all colors ■ in only one color ■ as a repeating or random defect 5-2 WorkCentre C2424 Service Manual
