Status Indicator RAPs
22-761 IQA Factor Set to Minimum RAP
22-761 The (IQA) image quality adjustment factor has been set to the minimum value (light).
The fault will occur if the test pattern is dark, but not dark enough to create a 22-451 fault. This
may result in subsequent image quality being too light, as the ROS output level may be too
low. Check in fault history to find a 22-761 failure.
Initial Actions
Load A4 (8.5x11 inch) white paper LEF in the Bypass Tray.
Procedure
Perform the following:
• Make print samples and if the images are dark or black refer to the IQ1 Image Quality
Entry RAP to resolve image quality defects for dark or black images.
• Check that the image quality adjustment factor in the NVM is not too high causing high
ROS light level output and very dark test pattern.
Enter dC131 location 06-04 (IQA) image quality adjustment factor and reset value to 100.
Reboot the machine and repeat the ADJ 9.2 Image Quality Adjustment Routine.
• Check in dC131 location 06-01 ROS light level, is correct and not set high. Enter dC131
location 06-01 ROS light level and reset value to default. Reboot the machine and repeat
the ADJ 9.2 Image Quality Adjustment Routine.
• Check that the developer bias is not set high. Enter dC131 location 09-021 developer bias
print level and reset value to default.
• If the fault still occurs the ROS output level may be too high. Go to the RAP 03-395, 396,
852, 853 IOT PWB Fault RAP.
