In one example a method comprises causing, by a processor, a nozzle of a printhead to discharge a printing fluid droplet toward a drop detector and receiving, from the drop detector, by a processor, a signal indicative of the location of the discharged printing fluid droplet. The example method comprises determining, by a processor, whether the location of the discharged droplet matches a stored location of the nozzle corresponding to a print mode. The example method comprises issuing, by a processor, a signal based on the determination.

Printhead positions

Examples relate to capping stations having caps with positioning mechanism. The capping station for a printing system may comprise a cap to seal a printhead and a positioning mechanism to move the cap between a first cap position and a second cap position.

Capping stations with positioning mechanisms

A dummy cartridge includes a body having an external shape dimensioned to be received in a cartridge pocket, and a handle integrated into the body, with cavities provided in the body on two opposite sides of the handle; wherein the cavities are dimensioned to allow insertion of a human thumb and/or finger on the two opposite sides of the handle for gripping the handle.

Dummy Cartridge

A printer carriage comprises a sensor to be actuated when an actuation member coupled to the sensor contacts a raised portion in a printing target. A vertical position of the actuation member may be adjusted with respect to the printer carriage.

Printer carriage with sensor

It is disclosed a print-head carriage comprising base and a tab with a rotatable connection to the base on a first end, the rotation of the tab defining a closed position in which a second end opposite to the first end is in contact with the base and an open position in which the second end is separated from the base, the base being adapted to receive a print-head along an insertion direction when the tab is in the open position wherein the tab further comprises a latch located at a position remote to the rotatable connection comprising a lever, that separates from the tab in an unlocked position and moves towards the tab in a locked position; wherein the latch comprises a biasing mechanism to bias the latch to the locked position.

Print-head carriages

In one embodiment, a roll spindle comprises two roll supports and a differential.
