Abstract

Analyze the information improvement from Ink Supply System to the user using RGB lights

instead of fixed colors.

Nowadays, in most of the LFP printers, the Ink Supply System has 3 colors signaling to

indicate the user the status of each ink supply. This kind of signaling is simple but it is fixed

in functionality and versatility to each LED color mounted on the PCA. Moreover, the cost of

this system is high because each LED of each ink supply must have a wire and a driver.

It would be desirable to have an indicator which gives a more flexible information to the user

(managing color, and intensity), cheaper, simpler to implement, easier to test and scalable.

The new RGB LED technology includes all the required electronics into each individual LED

using a simple daisy chain connection between them.
