Abstract
In some examples, a fluid ejection system can include one or more drive bubble devices and a sensor for each drive bubble device of the one or more drive bubble devices to detect a characteristic of each drive bubble device. The fluid ejection system can also include a controller. The controller can be configured to evaluate a first drive bubble device of the one or more drive bubble devices, and during the evaluation of the first drive bubble device, utilize one or more other drive bubble devices of the one or more drive bubble devices.
Claims17
A fluid ejection system comprising:
- a fluid ejection die comprising one or more drive bubble devices and a sensor for each drive bubble device of the one or more drive bubble devices to detect a characteristic of each drive bubble device;
- and
- a controller configured to:
- evaluate a first drive bubble device of the one or more drive bubble devices;
- and
- during the evaluation of the first drive bubble device, service another drive bubble device of the one or more drive bubble devices.
A method for evaluating a fluid ejection die, the method comprising:
- evaluating a first drive bubble device;
- and
- during the evaluation of the first drive bubble device, servicing another drive bubble device.
A printer system comprising:
- a fluid ejection die comprising a plurality of drive bubble devices in a first column, a plurality of drive bubble devices in a second column, and a sensor for each drive bubble device to detect a characteristic of each drive bubble device;
- and
- a controller configured to:
- evaluate a first drive bubble device in the first column;
- and
- service drive bubble devices in the second column responsive to initiating evaluation of the first drive bubble device.
