Abstract: In one example in accordance with the present disclosure, a refill container is described. The refill container includes a reservoir to house a volume of print compound and a chamber to house a pressurized fluid. A wall separates the reservoir from the chamber. A pressure release device of the refill container creates a fluid path between the chamber and the reservoir such that the pressurized fluid flows into the reservoir to mix with the volume of print compound. A trigger of the refill container activates the pressure release device.

Abstract: An image forming apparatus includes a toner cartridge, a light source, a light guiding device, and an optical sensor. The toner cartridge includes a developer member and a photosensitive member. The developer member receives toner and applies the toner to the photosensitive member. The light source emits light. The light guiding device guides the light from the light source at a plurality of areas on the developer member. The optical sensor detects an amount of reflected light reflected from the developer member.

Abstract: An apparatus includes a developer to receive a toner, and an actuator moveable between different positions. An electrical switch is responsive to an input stimulus from the actuator to control a voltage that enables or disrupts a transfer of the toner from the developer to a photoreceptor, where the electrical switch when in a first state sets the voltage at a first level to enable the transfer of the toner from the developer to the photoreceptor, and the electrical switch when in a second state sets the voltage at a second level to disrupt the transfer of the toner from the developer to the photoreceptor.

Abstract: A device receives information regarding whether a cover of an authentication indicia of a consumable has been subject to tampering. In response to the information indicating that the cover of the authentication indicia has not been subject to tampering, the device obtains an image of the authentication indicia after the cover has been removed from the authentication indicia. The device performs an authentication process to authenticate the consumable based on the authentication indicia.

Abstract: An apparatus includes a developer and a moveable support that is moveable in response to actuation by an image forming device. The apparatus further includes a toner transfer modulator on the moveable support, the toner transfer modulator moveable with the moveable support between different positions to differently affect transfer of a toner to a photoreceptor or a transfer member, where the moveable support is to move the toner transfer modulator to a first position to disrupt the transfer of the toner to the photoreceptor or the transfer member during an image forming operation of the image forming device.

Abstract: In some examples, a print material apparatus includes a housing having an opening and an inner housing space, and a module removably attached to the housing to cover the opening, the module providing an inner module space that together with the inner housing space define a volume containing a print material of the print material apparatus. The housing is attachable to different modules that provide respective inner module spaces of different sizes for defining different print material containment capacities of the print material apparatus.

Abstract: Example implementations relate to end-of-life determination for a print cartridge. For example, a print cartridge according to the present disclosure, may include a plurality of consumable components. Each of the plurality of consumable components may have an associated sensor to monitor use of the respective consumable component. The print cartridge may further include a memory including instructions executable by a processor to, for each of the plurality of consumable components, receive a past use value quantifying an amount and type of use of the respective consumable component, determine an end-of-life value for the respective consumable component using the past use value and a predetermined tuning factor for the respective consumable component, and determine an end-of-life value for the print cartridge based on the plurality of end-of-life values for the plurality of consumable components.
