摘要:
An aerosol extraction system for a fluid-ejection device is disclosed that includes a print zone, a servicing zone, a vacuum, and a switching mechanism. The print zone is that in which a print head of the fluid-ejection device ejects fluid onto media to form images thereon. The servicing zone is that in which the print head is serviced. The vacuum is fluidically connectable to both the print zone and the servicing zone. The switching mechanism is to fluidically connect and disconnect at least one of the print zone and the servicing zone to the vacuum.

A medium feeding system for a hardcopy apparatus comprising: a revolving arrangement for supporting a roll of medium, the revolving arrangement comprising a friction ring, the friction ring rotating around a friction ring rotation axis; and a braking element comprising two pivotally arranged jaws, whereby the friction ring is bitten by said jaws; whereby the braking element is rotatable around the friction ring rotation axis; and means to push the jaws against the friction ring; and means to pull the jaws away from the friction ring; whereby the means to pull the jaws away from the friction ring are triggered by the rotation of the friction ring.

A hardcopy device having a scanning head arranged to reciprocate across a scan axis, and first and second codestrips arranged substantially parallel to the scan axis, the first and second codestrips being offset from one another in the scan axis, such that the device may determine the position of the head along the scan axis relative to the first and second codestrips in a first set of positions but relative to only one of the first and second codestrips in a second set of positions.
