3-2 Xerox Internal Use Only Phaser 3010/3040/WorkCentre 3045 ServiceImage QualityImage Quality OverviewImage-quality defects can be attributed to printer components, consumables,media, internal software, external software applications, and environmentalconditions. To successfully troubleshoot print-quality problems, eliminate as manyvariables as possible. The first step is to generate prints using information pagesembedded in the printer on laser paper from the approved media list. Refer to“Media and Tray Specifications” on page 1-29 for supported and specialty mediathat have been tested and approved for use in the Phaser 3010/3040/WorkCentre3045s. Use paper from a fresh ream that is acclimated to room temperature andhumidity.If the print-quality defect remains after printing on approved media from anunopened ream of paper, then investigate applications and environmentalconditions.Determine the temperature and humidity under which the printer is operating.Compare this to the “Environmental Specifications” on page 1-24. Extremetemperature and humidity can adversely affect print quality.When analyzing a print-quality defect, first determine if the defect is repeating ora random occurrence. Continuous defects in the process direction, such as voidsand lines, are the most difficult to diagnose. Inspect the visible surfaces of allrollers for obvious defects.Defects Associated with Specific Printer ComponentsSome print-quality problems are associated with specific assemblies.
