Impact of Label Management Software and Print Media on LVS-7510 Functionality

[Omron Forums Support]

Impact of Changes to Label Management Software  

7510 does not require use of a specific brand or version of label management software.  LVS-7510 does not communicate information to a printer such as which label template to print, how many labels to print, data from a ERP or warehouse management system information to a printer such as the label template to print, how many labels to printer, data from a ERP or warehouse management system, or other print job specific information.  Prior to a print job being run the operator recalls an inspection template from the LVS-7510 production archive that is specific to the label design about to be printed.  It then waits for the labels to be printed and inspects the label based on what is printed.
If there is a change to the label management software (revision, vendor, etc.) there is no impact to the LVS-7510 system provided that the label which is printed is identical in terms of design (font, graphics, position of information).  If there are changes in the label output from the printer then the LVS-7510 software likely will trigger errors if functionality such as OCV and blemish detection are enabled.

Printer Resolution and Media Impacts on LVS-7510 Software

• During the installation of a LVS-7510 system the technician creates an inspection template using the labels printed by the actual printer and print media which is being used.   Since LVS-7510 is integrated directly into a printer it is not possible to exchange LVS-7510 into a different model printer.  However, if label designs are changed at a later point in time without a corresponding change to the LVS-7510 inspection template in many cases a label inspection error will occur.  Exceptions are if the changes made are not within one of the inspection “sectors” (regions of interest).
• If blemish detection is part of the inspection template and the sensitivity is set to a high level, then use of print media (labels) which is of a lower quality such that small defects in the blank labels trigger a blemish error then an adjustment to the blemish sensitivity may be required.  The change to blemish sensitivity can easily be performed by a trained operator. 
• Further, changes to printer ribbon type and/or label type will typically result in a change to inspection image such that a blemish error will be triggered.  This may require adjustment of the blemish setting to avoid false errors.

Finally, if the print head is changed to a lower resolution, such as changing from a 300 dpi to a 200 dpi print head, then in some cases the barcode or human readable text print quality may degrade to the point that label inspection triggers an error.  This could require a change to the inspection template
