摘要:
An image forming system and methods are disclosed. The methods include detecting an ambient temperature of an image forming system by a first thermal sense resistor disposed in a first printhead to obtain a first detected ambient temperature, detecting the ambient temperature of the image forming system by a second thermal sense resistor disposed in a second printhead to obtain a second detected ambient temperature, and determining a temperature difference between the first detected ambient temperature and the second detected ambient temperature of the image forming system by a temperature variation module.
摘要:
A continuous ink supply (CIS) apparatus, a CIS printer system and a method of CIS employ a one-way valve having a minimum negative activation pressure. The apparatus includes an off-axis ink supply to source liquid ink to a printhead of a printer. The one-way valve is positioned between the off-axis ink supply and the printhead. The minimum negative activation pressure at a printhead side of the one-way valve is at least enough to substantially precludes drooling from the printhead.

A consumable product can have an identifier stored on a circuit or machine-readable medium. The identifier can be used to verify the authenticity of the consumable product. The integrity of the identifier can be verified based on an integrity check portion of the identifier.
摘要:
Example methods, apparatus and articles of manufacture to update a supported-supplies database (110) of an image forming apparatus (105) are disclosed. A disclosed example method includes detecting insertion of an imaging supply (120) into an image forming apparatus (105), interacting with the inserted imaging supply (120) to obtain a supply identifier, the supply identifier representing an additional supported imaging supply for the image forming apparatus (105), and adding the obtained supply identifier to a supported-supplies database (110) of the image forming apparatus (105).
摘要:
A replaceable printing component is provided, including a fluid reservoir, an electrical storage device mounted on the fluid reservoir, and an identifier stored on the information storage device, wherein the identifier is fixed based on an initial volume of fluid stored in the fluid reservoir.
摘要:
In an embodiment, an authentication system includes a base unit to receive a replaceable supply device, a controller integrated into the base unit, known characteristic data accessible by the controller, and an authentication algorithm executable on the controller to authenticate the supply device if a known characteristic measured on the supply device matches the known characteristic data.

摘要:
A fluid ejection device for use with a print system to eject fluid onto a substrate includes a fluid reservoir and an identifier associated with the fluid reservoir, wherein the identifier is fixed and specifies a nominal fluid ejection rate of fluid from the fluid reservoir.
摘要:
A replaceable printer component includes a memory and a communication link The memory stores a tag encryption mask and data. The data is stored in a plurality of portions of the memory where each portion is defined by a tag. The tag encryption mask indicates an encryption status of each portion of the memory defined by a tag. The communication link is configured to communicatively link the memory to a printer controller when the replaceable printer component is installed in a printing system.
