Cause

Solution

Non-standard stains were detected.

There might be dirt in the paper feed path. Perform maintenance of the system.

For details, refer to [Execute Adjust Operation] or Maintenance.

Cause

Solution

The inspection accuracy may be set too high.

Lower the level of any of the following:

Inspection level

[Detection Level]

[Paper Noise Removal Level]

The actual printed paper differs from that of the reference image.

Load the paper that was used when creating the reference image.

Alternatively, load the actual paper type you are using and create a new reference image.

The scanner unit of Intelligent Quality Optimizer IQ-501 is dirty.

Clean the scanner unit.

For details, refer to Cleaning Intelligent Quality Optimizer IQ-501.

Cause

Solution

Non-standard streak-like dirt was detected.

Perform [Image Diagnosis]. Run a diagnosis to find the causes of various defects on images, including streaks and spots (white outlines, colored outlines, black and white blots or marks). Checking the diagnostics results and performing adjustments improves the stability of the image quality.

For details, refer to [Image Diagnosis].

Cause

Solution

Non-standard spot-like dirt was detected.

The reason for spots occurring is often contamination in the toner, so try reprinting in such cases.

If reprinting does not resolve the situation, run [Image Diagnosis]. Run a diagnosis to find the causes of various defects on images, including streaks and spots (white outlines, colored outlines, black and white blots or marks). Checking the diagnostics results and performing adjustments improves the stability of the image quality.

For details, refer to [Image Diagnosis].

Cause

Solution

There is an abnormality in the original data.

Alternatively, the settings are not in line with the specifications.

Check the inspection data and decoding results (CSV file in report).

Alternatively, check that the barcode area or serial number area settings are configured correctly in line with the specifications. For details, refer to [Select Area Type] and [Sequential Check].

Cause

Solution

There is either dirt on the reference image or a non-standard image omission has been detected.

Perform maintenance of the system, and create a new reference image.

Alternatively, lower the inspection level.

Cause

Solution

There is a positional alignment error between the reference image and inspected image.

For images with pale colors, or simple images with only ruled lines, positional misalignment may occur.

If errors continue to show up on specific images, try setting the all target pages as areas to be excluded from inspection with [Inspection Excluding Area].

For details about automatic inspection area settings, refer to Setting Inspection Areas.

There are large stains on the image.

Recreate the reference image if there is dirt on the reference image.

If there is dirt on the printed item, first perform maintenance of the system, and then run the automatic inspection once more.

The printed image is completely different than the reference image.

Check to see if the print job and reference image match. If you find no issues, recreate the reference image.

Cause

Solution

Although it falls within the standards, 100 stains or more were detected.

(As the stains are not outside the scope of the standards, there are no annotations (circled in red))

There might be dirt in the paper feed path. Perform maintenance of the system.

For details, refer to [Execute Adjust Operation] or Maintenance.

Cause

Solution

The paper size used for the print job differs from that used for the reference image.

Check to see if the print job and reference image match. If you find no issues, recreate the reference image.
