摘要： A system to carry print media through a print zone in a printer. In one example, the system includes an endless conveyor belt in a loop, a driver operatively connected to the conveyor belt under the print zone to circulate the conveyor belt through the print zone, an encoder operatively connected to the driver under the print zone to measure movement of the conveyor belt in the print zone indirectly through the driver, and a controller programmed to control the driver based on measurements from the encoder.

摘要： A drying assembly comprises a plurality of electromagnetic energy sources arranged to dry printing fluid deposited onto a surface of a substrate, by evaporation of a solvent fluid therefrom. The drying assembly further comprises a conveyor system configured to move the substrate in a conveying direction, and a focusing system configured to focus electromagnetic energy from the plurality of electromagnetic energy sources to form a non-uniform heating pattern on the surface of the substrate. The non-uniform heating pattern comprises a plurality of spatially separated higher and lower intensity regions distributed along the conveying direction.

摘要： In one example, a media support with a continuous belt rotatable and suction cups lengthwise along the belt and in lines laterally across the belt to hold down a sheet of print media as the sheet is moved through a hold down area, a vacuum pump to supply vacuum to the suction cups. The vacuum control system is configured to close a supply of vacuum to all of the suction cups in the hold down area and then open the supply of vacuum sequentially to each of multiple lines of suction cups as each line enters the hold down area and then close the supply of vacuum sequentially to each of the multiple lines of suction cups as each line leaves the hold down area until all of the suction cups in the hold down area are closed.

摘要： Examples described herein include a print media edge repair system that includes a first repair element disposed adjacent to a media handling path to repair a leading edge of a sheet of print media as the sheet of print media moves into a position relative to a printing system associated with the print media edge repair system. The print media repair system may also include a second repair element disposed opposite the first repair element across the media handling path to repair a trailing edge of the sheet of print media as the sheet of print media moves into the position relative to a printing system.

摘要： In an example, a print head includes a nozzle, a fluid channel to provide printing fluid to the nozzle and a Light Emitting Diode (LED). The LED may emit light to heat printing fluid in the fluid channel causing localised vaporisation of the printing fluid and ejection of a fluid drop through the nozzle.

摘要： A printer dryer device comprises a first drying unit, wherein the first drying unit comprises a first plurality of energy-emitting elements to dry a printing substance on a printing medium, wherein the first plurality of energy-emitting elements are electrically connected in series in the first drying unit. The printer dryer device further comprises a second drying unit, wherein the second drying unit comprises a second plurality of energy-emitting elements to dry the printing substance on the printing medium, wherein the second drying unit is arranged downstream from the first drying unit in a medium transport direction of the printing medium, and wherein the second plurality of energy-emitting elements are electrically connected in series in the second drying unit. At least one energy-emitting element among the second plurality of energy-emitting elements is not electrically connected in series to an energy-emitting element among the first plurality of energy-emitting elements.
