Operating Cautions
This section describes cautions regarding using the inspection system.
System Requirements
Since the Inspection Tool processes a large amount of image, text, and barcode data, it needs to be able to fully use the performance of the computer processor. Therefore, the Inspection Tool might not operate correctly if another application is running at the same time.
Computer Fan Noise
The computer that runs the Inspection Tool is configured to have the fan run faster than a typical computer in order to prevent the computer from getting hot. Because of this, the fan noise is louder.
Do not change the fan speed, because the computer and Inspection Tool might not function correctly if you reduce the fan speed.
For paper where the width exceeds 303 mm
For paper where the width (main scanning direction) exceeds 303 mm, images, text, and barcodes within the right and left sides of the paper cannot be inspected. Images within the 303 mm range in the center of the paper can be inspected.
When paper like this is used, folded corners might not be detected if they occur. Furthermore, if there are overlapping folded parts in the area subject to inspection, it may be detected as streaks. (Folded corners that occur in paper with width of 303 mm or less will be detected as "Inspection Error".)
When paper like this is used, a diagonal line pattern as shown below is displayed in the areas that cannot be inspected on each side of the paper on each of the screens that display images.
: Paper width of 303 mm or more
: 303 mmWhen printing two-sided on pre-printed paper
When printing two-sided on pre-printed paper, the paper may need to be loaded upside-down depending on the combination of output paper face and output paper tray.
Output paper face | Output paper tray | ||
The High Capacity Stacker attached | The High Capacity Stacker not attached | ||
High Capacity Stacker: Stacker | Finisher High Capacity Stacker: Sample tray | All output paper trays | |
Face up specified | Load upside-down | Load upside-down*1 | Load upside-down |
Face down specified | Load the paper in the correct orientation (front/back) based on the paper tray type. | Load the paper in the correct orientation (front/back) based on the paper tray type.*2 | Load the paper in the correct orientation (front/back) based on the paper tray type. |
*1 | When executing an inspection using the Inspection Tool, load the paper in the correct orientation (front/back) based on the paper tray type. |
*2 | When executing an inspection using the Inspection Tool, load upside-down. |
NOTE |
When using an external finisher, check the orientation (front/back) to load the paper by using a test print. |
Images with Few Edge Features
When images with few edge features are inspected, errors might occur frequently or output paper might be frequently judged as defective. This is because the position alignment between the master image and the image to be inspected cannot be performed correctly.
Examples of images with few edge features:
Images where there is text, etc. in only a very small part of a blank page
Images that only have light gradation
In this kind of situation, perform any of the following handling depending on the characteristics of the images and the purpose of printing.
Add crop marks or trim marks to clarify the position of the image.
Reduce the inspection level of the area that contains the corresponding image.
Exclude the area that contains the corresponding image from inspection.
Detection of Defects (Spots and Streaks) in Images
Defects such as spots and streaks might not be detected depending on the image contrast and the characteristics of the image. The defect detection function of the inspection system is not guaranteed to detect all visible streaks or spots as defects.
Maximum Number of Areas
The number of barcode areas that can be inspected*1 is found by converting the barcode inspection areas into a number of text inspection areas and then adding this to the number of text inspection areas. Since this is not an exact figure so use it as a rough guide.
*1 | The number of barcode areas that can be inspected varies depending on the paper size of the printed matter to be inspected. |
For paper where the length in the paper feeding direction is less than 355.6 mm (A5R/A4/A4R): Up to 15 locations each on front and back
For paper where the length in the paper feeding direction is 355.6 mm or more (A3/SRA3): Up to 25 locations each on front and back
Example:
If the paper size is A3, there are both QR codes and text inspection areas, and the number of QR code (1530 alphanumeric characters) areas is two
If the paper size is A3, there are both QR codes and text inspection areas, and the number of QR code (1530 alphanumeric characters) areas is two
→Convert the number of QR code areas to the number of text inspection areas: 2 × 5 = 10 areas
→Number of text inspection areas is up to 25 - 10 = 15
Barcode type | Conditions | Number of text inspection areas equivalent to 1 barcode area with processing taken into account |

Reading Text and Barcodes
Text and barcodes might not be able to be read correctly depending on the text and barcode printing state.
The text and barcode reading function does not guarantee 100% accuracy.
