In some examples, an apparatus can include a print material cartridge, a reciprocating pump, a first valve, where the first valve is a one-way valve, and a second valve, where the second valve is a float valve, where the reciprocating pump is to cause print material to be supplied to the print material cartridge via the second valve.
According to some examples, a skew detection device comprises a first roller rotatable around a first axis, a second roller rotatable around a second axis, a first sensor, and a second sensor. The first sensor measures a first rotation parameter from the first roller and the second sensor measures a second rotation parameter from the second roller. A movement of a print media over the device rotates the first contact roller and the second roller, and a controller determines a skew of the print media based on the first and second rotation parameters captured by the first sensor and the second sensor.

B65H 7/06 - Commande de l'alimentation en articles, de l'enlèvement des articles, de l'avance des piles ou d'appareils associés permettant de tenir compte d'une alimentation incorrecte, de la non présence d'articles ou de la présence d'articles défectueux par palpeurs ou détecteurs sensibles à la présence d'articles défectueux ou à l'enlèvement ou à une alimentation incorrecte
An example of an inkjet ink composition includes an aqueous vehicle, a colorant dispersed or dissolved in the aqueous vehicle, silica nanoparticles dispersed in the aqueous vehicle, and modified silica nanoparticles dispersed in the aqueous vehicle. Each modified silica nanoparticle includes a silica core as well as a hydrophobic silane coupling agent attached to the silica core.
