Abstract
A printing device has a number of discrete components in a path traversed by print media. The number of uses of each discrete component in the print path is individually monitored and recorded. The number of individual uses of at least one discrete component is provided at the printing device and/or over a communications network.
Claims17
A method for facilitating the replacement of discrete print media path components within a printing device, each discrete print media path component having a service life measured in number of uses, comprising:
- monitoring a plurality of discrete print media path components of said printing device;
- and
- recording the number of individual uses of said plurality of discrete print media path components.
A method for facilitating the replacement of discrete print media path components within a printing device, each discrete print media path component having a service life measured in number of uses, comprising:
- monitoring the discrete print media path components of said printing device;
- recording the number of individual uses of the discrete print media path components;
- providing said number of times the discrete print media path components have been used;
- comparing the number of times each discrete print media path component has been used with the service life of each discrete print media path component;
- replacing only said discrete print media path components that have been used a number of times at least equal to said service life of said discrete print media path component.
