22-452 Test Pattern Average Grey Level Too High RAP
22-452 The image quality adjustment routine has determined that the average grey level of the
test pattern is too high. The grey part of the test pattern as measured by the scanner is too light
(i.e. high greys levels = light). If this fault occurs the (IQA) image quality adjustment factor will
not be re-adjusted and will stay as it is. Subsequent IQ will not be altered.
Initial Actions
Load A4 (8.5x11 inch) white paper LEF in the Bypass Tray.
Procedure
Perform the following:
1.
Check that the test pattern was fed through the document handler the correct way up.
2.
Make print samples and if the images are light or white refer to
IQ1
Image Quality Entry
RAP to resolve image quality defects for light or white images.
3.
Check that the image quality adjustment factor in the NVM is not too low causing a high
ROS light level output, and very light test pattern. Enter
dC131
location 06-04 (IQA)
image quality adjustment factor, reset value to 100. Reboot the machine and repeat the
ADJ 9.2
Image Quality Adjustment Routine.
4.
Check in
dC131
location 06-01 ROS light level, is correct and not set low. Enter
dC131
location 06-01 ROS light level, reset value to default. Reboot the machine and repeat the
ADJ 9.2
Image Quality Adjustment Routine.
5.
Check that the developer bias is not set low. Enter
dC131
location 09-021 developer bias
print level and reset value to default.
6.
If the fault still occurs the ROS output level may be too low. Go to the RAP
03-395, 396,
852, 853
IOT PWB Fault RAP.
22-760 IQA Factor Set to Maximum RAP
22-760 The (IQA) image quality adjustment factor has been set to the maximum value (dark).
The fault will occur if the test pattern is light, but not light enough to create a 22-452 fault. This
may result in subsequent image quality being too dark, as the ROS output level may be too
high. Check in fault history to find a 22-760 failure.
Initial Actions
Load A4 (8.5x11 inch) white paper LEF in the Bypass Tray.
Procedure
Perform the following:
1.
Check that the test pattern was fed through the document handler the correct way up.
2.
Make print samples and if the images are light or white refer to the
IQ1
Image Quality
Entry RAP to resolve image quality defects for light or white images.
3.
Check that the image quality adjustment factor in the NVM is not too, low causing high
ROS light level output, and very light test pattern. Enter
dC131
location 06-04 (IQA)
image quality adjustment factor, reset value to 100. Reboot the machine and repeat the
ADJ 9.2
Image Quality Adjustment Routine.
4.
Check in
dC131
location 06-01 ROS light level, is correct and not set low. Enter
dC131
location 06-01 ROS light level, reset value to default. Reboot the machine and repeat the
ADJ 9.2
Image Quality Adjustment Routine.
5.
Check that the developer bias is not set low. Enter
dC131
location 09-021 developer bias
print level and reset value to default.
6.
If the fault still occurs the ROS output level may be too low. Go to the RAP
03-395, 396,
852, 853
IOT PWB Fault RAP.
