IQ1 Image Quality Entry RAP
Use this RAP to determine the source of an image quality problem.

Initial Actions
Perform the steps that follow:
  • Discuss the IQ problem with the customer to fully understand the defect and the modes in which it occurs. Produce the customer job that displays the customer’s IQ defect.
    NOTE: If the customer is using Toner Save mode, explain that this will lighten the image to save toner. Standard mode (toner save disabled) should be used for image quality problem solving.
    NOTE: When border erase is switched off, an image defect within 5mm of the sheet edge is acceptable. Border erase only affects the printed image from the IOT, so scanned images saved to USB stick will have edge to edge images.
    NOTE: Long runs of duplex or running LVF BM jobs may result in lighter prints. If this occurs adjust the darkness using the Darken Image tool on the UI. From the UI select Device then Tools. Scroll down to Darken Image. Check the position of the Darken Image tool and reset to zero before proceeding.
  • Enter Customer Administrator Tools, GP 24. Press the Machine Status button. Select Device / Tools / App Settings / Copy. Disable the Toner Saver mode if it is not already disabled. At the end of the IQ procedure, set the Toner Saver mode back to the original setting.
  • Check the condition of the paper. Do not use incorrectly cut paper, damp paper, paper with rough edges, badly drilled paper, paper with wrapper wax or glue. Paper and media should be stored flat, enclosed in wrappers, in a cool dry environment.
  • Check that the paper is within specifications, GP 20.
  • Check that paper tray guides are set to the correct paper size.
  • Check that the document guides on the SPDH are set correctly.
  • Check the original documents for defects. If the documents are damaged passing through the SPDH, perform the 305C Damaged Documents RAP.
  • Go to dC122 Fault History. Check for any fault codes associated with the print cartridge, fuser module, LED print head or the paper path from the registration roll, PL 80.17 Item 5 to the fuser module, PL 10.8 Item 1. These may contribute to image quality faults. If found, fix these faults before continuing with this RAP.
  • Clean the paper path sensors that follow:
    – Tray 1 TAR sensor, PL 80.10 Item 5.
    – Tray 2 TAR sensor, PL 80.10 Item 5.
    – Registration sensor, PL 80.17 Item 7.
    NOTE: The Scan to USB option must be made available by the System Administrator. If Authentication or Accounting has been enabled on the device, you may have to enter login details to access the Scan To features.

IQ1 Image Quality Entry RAP
Use this RAP to determine the source of an image quality problem.

Procedure:
  1. Enter dC612 Print Test Patterns. Select test pattern 21 (ITP 11 Error Diffused IOT TRC+MQ).
    Select simplex. Select quantity 3. Select Start Test. The printed image of the second print is good, with reference to IQS 1 Solid Area Density and Tone Reproduction.
    Y: Go to step 10
    N:
    Perform the actions that follow:
    • Check the condition of the paper. Do not use incorrectly cut paper, damp paper, paper with rough edges, badly drilled paper, paper with wrapper wax or glue. Paper and media should be stored flat, enclosed in wrappers, in a cool dry environment.
    • Check that the paper is within specifications. Refer to GP 20.
    • Check that paper tray guides are set to the correct paper size.
    • Check the original documents for defects. If the documents are damaged passing through the SPDH, perform 305C Damaged Documents RAP.
    • Ensure that the image adjustment mode selections are those used by the customer.
    • Perform ADJ 60.4 LED print head Cleaning.
  2. Produce the customer job that displays the customer’s IQ defect. The image quality fault persists.
    N: Perform SCP 5 Final actions.
    Y:
  3. Select a suitable internal test pattern to diagnose the IQ problem. If necessary, refer to IQ1 Internal Test Patterns for:
    • A description of image quality defects together with the optimum internal test pattern to be used to diagnose the IQ defect, Table 1.
    • A chart of the internal test pattern descriptions together with their intended use, Table 2.
    • Example images of all internal test patterns, Figures 2 to 20. Enter dC612 Print Test Patterns. Select the required internal test pattern. Select simplex. Select Start Test. The printed image of the internal test pattern is good.
    N: Perform the IQ2 IOT IQ Defects RAP.
    Y:
  4. Check the back of the prints for toner contamination. The back of the prints are clean.
    N: Perform the IQ2 IOT IQ Defects RAP.
    Y:
  5. Select a suitable duplex internal test pattern. Select duplex. Select Start Test. The printed images of the internal test pattern are good.
    N: Perform the IQ2 IOT IQ Defects RAP.
    Y:
  6. Check the prints for damage. The prints are good.
    N: Perform the IQ5 Print Damage RAP.
    Y:
  7. If a fax module is installed, send a test fax to the machine. The fax image quality is good.
    Y: Go to step 9
    N:
  8. If a fax module is installed, send a test fax to the machine. The fax image quality is good.
    N: Perform the IQ9 Unacceptable Received Fax Image Quality RAP.
    Y: Perform the IQ2 IOT IQ Defects RAP.
  9. No specific image quality defect has been identified. If necessary, modify the print quality to meet the customer requirements. Refer to the IQ11 Print Quality Improvement RAP.
  10. Make a simplex scan to USB file of test pattern 82E2010 (A4) or 82E2020 (8.5 x11inch) from the document glass. Ensure that the test pattern is correctly registered against the document guides and is not disturbed when the SPDH is lowered. Scan 3 times. View the resultant file on a computer screen. The file image of the second image is good.
    N: Perform the IQ7 Document Glass and Scanner IQ Defects RAP.
    Y:
  11. Place the test pattern 82E2010 (A4) or 82E2020 (8.5 x11inch) face down in the SPDH input tray. Check the document guides on the SPDH are set to just touch the test pattern. Make a duplex scan to USB file. Scan 3 times. View the resultant file on a computer screen. The file image for side 2 of the second image is good.
    N: Perform the IQ12 Side 2 Scanner IQ Defects RAP.
    Y:
  12. No specific image quality defect has been identified. If necessary, modify the print quality to meet the customer requirements. Refer to the IQ11 Print Quality Improvement RAP.
