In an example, a conditioner module may include a bridge to receive media from a media path of an imaging device and to deliver the media to a media input of a finisher module. The conditioner module may include a calender nip disposed at an output end of the bridge. The calender nip may compress the media and may feed the media into the media input of the finisher module.

Conditioner modules with calender rollers

In one example, a system for partially dried inkjet media fusers include a plurality of fusers aligned to receive partially dried inkjet media from a printing device, wherein the plurality of fusers each comprise a top roller and a bottom roller to apply pressure to the received partially dried inkjet media, and a finisher to receive the partially dried inkjet media from the plurality of fusers.

Partially dried inkjet media fusers

Examples of a printhead assembly are disclosed herein. An example of the printhead assembly includes a die to print, a base member, and at least one electrode. The electrode may be used to provide a charge to attract and collect particles that would normally otherwise interfere with operation of the die.

Methods of compensating for position errors due to signal scaling, linearity, and offset between first and second members in a displacement transducer are provided, including: producing a first signal at the first member; producing a second signal at the first member; modulating the first signal at the second member to include at least one region with an invariant amplitude as the first and second members are displaced relative to one another along a measurement axis; determining a relation between a sample of the second signal and the invariant amplitude of the first signal as an indication of an error parameter; and generating a compensated sample based upon the determined relation.

Compensating for position errors in displacement transducers

Embodiments of electrostatic blower system for use in computer systems or other electronic device, e.g., in inkjet printers for cooling or drying operations, are disclosed. An exemplary method may include arranging a plurality of electrostatic blowers together to increase output pressure. The method may also include positioning the arranged electrostatic blowers directly adjacent a point of use in a printer device. The method may also include directing and accelerating airflow using a corona discharge in each of the plurality of electrostatic blowers for cooling or drying operations in the printer device.

Electrostatic blower systems

In one embodiment, an aerosol trap for an inkjet printer includes a conductor at least partially surrounding ink ejection nozzles such that, when the conductor is charged, aerosol generated when ink is ejected from the nozzles is contained by the conductor, and a source of electric power operatively connected to the conductor.

Electrostatic aerosol control

Embodiments of a system and method for directing aerosol are disclosed.
