This article applies to most machines which use the JCM iVIZION. For other validators, please record the blink codes and file a support ticket.
If your machine experiences consistent bill rejection, either of a specific denomination or overall, this can often be resolved with a few steps.
Counting blink codes
For more information on why the notes are rejected, let's count the blink codes on the bill validator when inserting a note.
To do so, remove the front plate of the vault with a hex screw.
Conduct a transaction while observing the area in yellow in this picture.
After it rejects a bill, notice the color and number of blinks the LED light makes (it will repeat the sequence). Here's a video of the validator rejecting a bill, and giving 6 green blinks (repeated) for the code.
The validator's quick reference guide describes what each code signifies. Please reach out with what you find and we can provide further recommendations base on the code.
Cleaning the bill path
Generally, the first recommendation is to clean the bill path, as particles from bills can build up, obscuring the notes to the validator's optical sensors.
In which case, with the front plate off, remove the validator from the vault by pulling it straight out and disconnecting the cabling at the black juncture.
From there you can remove the bill feed unit and open it.
Please clean only with a dry lint cloth (such as an eyeglass towelette.) You should also check the stacker path for obstructions and clean it as well.
Please also refer to the Preventative Maintenance Guide.
If rejections continue, or the blink code indicates a solution other than cleaning, please file a support ticket. We can collect further information by downloading the validator logs. In some cases, a firmware update may be available which improves acceptance of particular denominations.
