3.3.4.3 Ink leak detection function
A sensor for detecting an ink leak is provided in this product in order to enable
the quick detection of an ink leak when an ink leak occurs from the ink supply
path due to an abnormality in the product.
The Ink Leak Sensor is provided inside the Ink Pack Unit, and detects an ink
leak by the adherence of ink on it (Porous Pad Cap Lower) when an ink leak
occurs. It also generates an ink leak error in the printer.
