Abstract
In an example, a method comprises fabricating a first validation device for association with a first replaceable print apparatus component. The device may be to form part of circuitry arranged on the first replaceable print apparatus component, and may provide an associated electrically detectable characteristic which varies with the position of at least part of the first validation device. The electrically detectable characteristic may be measured and data indicative of the characteristic may be stored in a first memory. The first replaceable print apparatus component comprising the first device and the first memory may be assembled.
Claims18
A method comprising:
- fabricating a first validation device for association with a first replaceable print apparatus component, wherein the first validation device is to form part of circuitry arranged on the first replaceable print apparatus component and provides an associated electrically detectable characteristic that varies with a position of at least part of the first validation device;
- measuring the electrically detectable characteristic, to generate data indicative of the electrically detectable characteristic;
- storing the data indicative of the electrically detectable characteristic in a first memory;
- and
- assembling the first replaceable print apparatus component comprising the first validation device and the first memory storing the data indicative of the electrically detectable characteristic.
A replaceable print apparatus component comprising:
- a memory and circuitry comprising a validation device,
- wherein an electrical characteristic of the circuitry is variable in response to a stimulus applied to the replaceable print apparatus component that displaces at least part of the validation device, and
- the memory stores measured data generated based on a response of the circuitry to the stimulus.
