In an example, an apparatus is described that a fluid ejection device to dispense fluid. A local service controller controls dispensing of the fluid by the fluid ejection device under a direction of a fluid ejection controller. The local service controller also initiates, autonomously of the fluid ejection controller, capping of the fluid ejection device in response to the detection of a failure condition by the local service controller. Capping mechanics are provided to cap the fluid ejection device under the direction of the local service controller.

In an example implementation, a method of adjusting frame length in an inkjet web press includes measuring a time T1 between a first sensor sensing a first mark and a second sensor sensing a second mark, and measuring a time T2 between the second sensor sensing the second mark and the first sensor sensing a next first mark. The method includes adjusting a gap between printed frames when T1 does not equal T2.

An optical disc is rotated using a spindle motor of an optical disc device, at no more than 600 revolutions per minute (RPM). The spindle motor has at least three coil groups, where each coil group has one or more coils. While the optical disc is rotating, at least one of the coil groups generates a back electromagnetic force (EMF) signal. The back EMF signal is used to determine marking positions on the optical disc. An optical beam is used to mark the optical disc at the determined marking positions.
