Liquid Ejecting Head Bypass Outlets for Bubble Expulsion

The single bypass channel is divided into multiple separate bypass channels. Each bypass channel provides an independent pathway for bubble expulsion, allowing bubbles to be removed more efficiently through multiple simultaneous exit points rather than a single bottleneck channel.

The bypass channels are configured to extend in multiple spatial directions from the upstream chamber to the collection opening. This multi-dimensional arrangement increases the surface area for bubble attachment and provides multiple geometric pathways, enhancing bubble expulsion ease compared to a single linear bypass.

The flow path is segmented into multiple parallel channels including bypass channels that can operate independently. When the filter becomes clogged, ink can still flow through the bypass channels, maintaining overall flow rate while the filter continues to capture foreign matter.

The bypass channels act as intermediary pathways that provide an alternative route for ink flow when the main filtered path is obstructed. This mediator structure allows the system to maintain productivity even when the filter is heavily loaded with captured foreign matter.

Multiple bypass channels provide multiple independent pathways for bubble escape from the upstream chamber. This segmentation of the expulsion path prevents bubble accumulation and stabilizes chamber pressure while maintaining clear access to the filter surface.

The bypass channels enable continuous bubble expulsion from the upstream chamber, preventing intermittent pressure variations. This continuous action maintains stable chamber pressure and ensures the filter surface remains consistently accessible for capturing foreign matter.
