Overview

Note: If the Paper Path is not clean, the Full Width Array, EZ Press Check, PredictPrint or Maintenance Routines may not complete successfully For additional information refer to How To Clean the Entire Paper Path. Tools to Ensure Production Consistency: The Automatic Image Management System works in concert with the ACQS and FWA tools to provide on-going image quality for superior production consistency How these tools achieve the different time requirements for consistency is shown below: Uniformity of toner Auto Alignment Adjustment using FWA 2nd Bias Transfer Roll Auto Adjustment Color Calibration Profiling Important: While these IQ tools are either automatic or semi-automatic - and they will save you alot of time - you still need to use them at the right time to keep your press tuned for optimum quality. Best Practices: Use the following best practices to optimize your quality output and save time attending to color and registration problems:               Image Quality Troubleshooting: Several factors, in addition to completing maintenance tasks, can affect the image quality of your printed output. When printing a sample of your job and before calling for Service, ensure: Humidity levels of the room are within the press specification. Refer to the Environmental Specifications to make sure conditions are within the limits. You have the appropriate stock type and weight for the press Refer to the Media Specifications for All Trays to make sure the stock is acceptable. This section contains a list of image quality artifacts that can occur on your printed output and the actions you can take to improve or resolve the issues. Use the Automated Adjustments function to perform an EZ Press Check at lease once a week, and after any of the xerographic components have been serviced.   Optimize the settings for the 2nd Bias Transfer Roll Auto Adjustment initially for new stocks, especially heavy-weight and specialty media Also, perform this adjustment when you notice problems with the way color appears (for example, mottle [uneven toner coverage] or color shift [inconsistent color]).   Calibrate the print server on a daily basis, and before color-critical jobs This procedure adjusts print server color settings, and is essential to maintaining color consistency Either the Full Width Array or a hand-held spectrophotometer can be used.   Before creating or updating Destination Profiles, first run the 2nd Bias Transfer Roll Auto Adjustment and then perform the Auto Desnsity Uniformity Adjustment Running these adjustments first ensures the best possible color from the new profiles you are creating.   Create Destination Profiles for each stock type used in color workflows This is critical for stocks with different coatings, gloss levels, colors or "white points" and paper weights The profiling process develops a map so that output colors on selected media will accurately replicate a known standard such as GRACol or SWOP Make sure that you associate each new profile with a specific stock so that it is used when the stock is selected. Humidity levels of the room are within the press specification. Refer to the Environmental Specifications to make sure conditions are within the limits. You have the appropriate stock type and weight for the press Refer to the Media Specifications for All Trays to make sure the stock is acceptable.
