Simple Image Quality Adjustment (SIQA) Tools Overview

CAUTION:
If using the Optional Xerox Adaptive CMYK Plus Technology:

  • Do not calibrate with Vivid or Fluorescent toner targets or any specialty color toners. Specialty toners do not use a calibration or color profile. Calibration and Profiling should be done on Process color CMYK mode only.

  • If CMYK color accuracy is critical then calibration and profiling should be done after swapping out of a specialty toner set.

Simple Image Quality Adjustment, or SIQA, is a set of maintenance tools that adjust the quality of the printed images generated by the device.
IMPORTANT: SIQA performs three types of adjustments, which must be performed in the following order:

  1. Image Transfer Adjustment: This tool corrects for uneven toner and color shift by creating an Image Transfer Adjustment to the Bias Transfer Roll in the device. The adjustment is created and saved for specific stocks and can be selected for any tray when printing on those stocks. Perform the Image Transfer Adjustment before performing any other image adjustment.

  2. Alignment (Auto Alignment Adjustment): This procedure generates an individual alignment profile for each stock and tray combination you select when performing the procedure. These profiles ensure correct placement of images on the media. You can create a maximum of 50 profiles. Each created profile is then used automatically each time the associated stock is used, ensuring optimal print quality. Perform Alignment Adjustment after you have completed the Image Transfer Adjustment.

  3. Density Uniformity: This procedure adjusts print engine tables, which ensures that ink is deposited uniformly and consistently across the entire surface of a page for each print. Perform the Density Uniformity Adjustment after you have completed the Image Transfer and Alignment Adjustments.

Device calibration with the SIQA tools consists of the following sets of steps:

  1. Print the SIQA targets.

  2. Scan the targets using the Document Feeder or the Platen Glass (document glass).

  3. Save the adjustment data to a file on the device and give the file a unique name.

After the adjustment profile is complete, users can select the profile for print runs, as needed.

Accessing the SIQA Tools

To access the SIQA tools:

  1. At the device control panel, log in as Administrator, press the Machine Status button, then touch the Tools tab. For details, refer to Access the Control Panel or Embedded Web Services (EWS).

  2. In the Features column, scroll down and touch Maintenance.

  3. To access the SIQA tools on the next screen, touch the down arrow.

Image Orientation Definitions

Inboard and outboard are as follows:

  • On the device,inboard andoutboard are defined as follows:

    • Inboard: This term refers to the rear of the device, which is the side of the device that is farthest from you as you are using the device.

    • Outboard: This term refers to the front of the device, which is the side of the device that is nearest to you as you are using the device.

  • On the printed output, as you hold the sheet with the top facing up, inboard refers to the left side of the sheet and outboard refers to the right side of the sheet. The short black line indicates the top of the sheet. The top of the sheet is also referred to as the lead edge.

Image Transfer Adjustment

The purpose of the Image Transfer Adjustment is to correct for mottle (uneven toner coverage) and color shift (inconsistent color). These image quality issues may occur on heavy-weight stocks. The Image Transfer Adjustment applies only to the media type selected during the procedure. You must perform this adjustment for each media type loaded in the device.

IMPORTANT: It is important to perform Image Transfer Adjustment before performing Auto Alignment Adjustment or Density Uniformity Adjustment.

Adjust Image Transfer

The Image Transfer Adjustment applies only to the paper type selected during the procedure. You must perform this adjustment for each paper type loaded in the device.

To perform a Simple Image Quality Adjustment (SIQA) for image transfer:

  1. At the device control panel, log in as Administrator, then access the SIQA Tools. Refer to Access SIQA.

  2. Touch Adjust Image Transfer.

  3. Touch Paper Type, then select a paper type from the list.

  4. Touch Close.

  5. Load the selected paper type into Tray 5 (bypass).Acceptable paper sizes:

    • 11 x 17 in.

    • 8.5 x 11 in.

    • A4

    • SRA3

  6. Touch Print Sample.

  7. Select a paper size.

  8. Select 1 Sided or 2 Sided for the calibration chart.

  9. To print the calibration chart, on the control panel, press the Start button.

  16. To complete and save the calibration, touch Adjust.

  17. To exit the SIQA tool, touch Close, then touch Close again.

  18. To log out of Administrator mode, on the top right corner of the screen, select the Admin icon, then touch Logout.

Adjust Image Transfer Manually

If you are not satisfied with the results achieved after completing the Image Transfer Adjustment procedure, you can run the calibration again using a different row of squares on the calibration chart. You can also change the adjustment values directly.

  1. Select the row of transfer samples that you wish to use for the calibration.

    Note: The key to choosing the best row of samples is to select a row with the fewest white spots in each square.

    pick row from sample

  2. Type the number that represents the desired sample row. The number for the row appears next to the row on the side of the sheet.

    Using the image above as an example, for Side 1 type 1 and for Side 2, type 5

  3. To save the values for image adjustment, touch Adjust.

  4. To exit the SIQA tool, touch Close, then touch Close again.

  5. Touch Close.

  6. To log out of Administrator mode, touch the Admin icon on the top right corner of the screen, then touch Logout.

Auto Alignment Adjustment

The Auto Alignment procedure generates an individual alignment profile, or Type, for each stock/tray combination selected when performing the procedure. These Types ensure that images are placed correctly on the media. You can create up to 50 Types. Each time a stock is used, the Type associated with the stock/tray will be used automatically, ensuring optimal print quality.

IMPORTANT: Before you can perform Auto Alignment Adjustment, you must perform Image Transfer Adjustment. For details, refer to Image Transfer Adjustment.
