The present disclosure relates to a low friction roller liner for a printer assembly that may include a core layer, a first outer layer overlying a first surface of the core layer, a second outer layer overlying the first outer layer, a first inner layer overlying a second surface of the core layer that is opposite of the first surface of the core layer, and a second inner layer overlying the first inner layer. The first outer layer and the first inner layer may include a fluoropolymer material and may have a melt flow rate of at least about 2 g/10 min at 372 C. The second outer layer and the second inner layer may include a fluoropolymer material distinct from the fluoropolymer material of the first outer layer and may have a surface coefficient of friction of not greater than about 0.2.

A roller for a transport belt of a vacuum transport assembly includes an elongate cylindrical body adapted for a rotatably fixed connection to a vacuum transport assembly. An outer surface of the roller defines a hollow inner channel, which extends along an axial region of the body. The outer surface is a running surface for a transport belt. An inlet at one end of the hollow inner channel receives air from an air source. Perforations are formed in the outer surface for allowing air pressure to be discharged from the hollow inner channel toward the transport belt. The air diffuses through the transport belt to detack a sheet from the transport belt.

A printer includes a printhead assembly and a dryer. A transport mechanism conveys the printed media in a downstream direction between the printhead assembly and a dryer and between the dryer and an output device. The transport mechanism includes an electric field-generating transport member. The transport member includes a continuous belt supported by rollers. The belt is driven to transport the printed media on an upper surface of the belt. The belt includes an electrically-insulating inner layer and an electrically-insulating outer layer. First and second sets of electrical conductors are positioned intermediate the inner and outer layers. Electrical conductors in the second set are grounded and alternate with electrical conductors in the first set, A charging unit selectively applies a voltage to only a subset of the electrical conductors in the first set at a time, to electrostatically attract the printed media to the upper surface of the belt.

A printer is provided for printing marking strips having a plurality of marking elements for marking electric devices which can be arranged next to one another. Each of the marking elements has a marking plate with at least one writing field which can be printed with information such as writing. The printer has a rotatably mounted feed shaft which can be driven by a motor and a printing head. The rotatably mounted feed shaft has at least one section which is provided with protrusions and which rests directly against the marking strip while the feed shaft is rotated such that the advancing speed of the marking strip is synchronized with the circumferential speed of the feed shaft.
