Upon fulfillment of a replacement cartridge of print material, whether projected usage of a printing device will likely deplete a current cartridge of print material prior to anticipated arrival of the replacement cartridge is determined. Responsive to determination that the projected usage will likely deplete the current cartridge prior to the anticipated arrival of the replacement cartridge, the printing device is to enter a reduced print material usage mode during subsequent actual usage of the printing device.

Printing device entry into reduced print material usage mode

The location of a printing device is determined. Environmental conditions in which the printing device operated when printing a print job are determined based on the determined location. An environmental adjustment factor for the printing device is determined based on the determined environmental conditions. A predicted print material usage of the printing device in printing the print job is adjusted based on the determined environmental adjustment factor.

Predicted print material usage adjustment

In response to detecting that a remaining supply of print material of a first cartridge has reached a first threshold, a printing device transmits a request. In response to detecting that a second cartridge has replaced the first cartridge, the printing device determines whether the remaining supply had reached a second threshold and whether a token permitting usage of the second cartridge was received responsive to the request. In response to determining that the remaining supply had reached the second threshold and that the token was received, the printing device prints with print material from the second cartridge.

Token permitting print material cartridge usage

An example method comprises identifying a plurality of supply levels corresponding to a set of print supplies of a print device. The example method further comprises coordinating depletion of the set of print supplies by selecting between black print and process black print for a print job of the print device based on the plurality of supply levels.

Selecting between black print and process black print

An example apparatus includes a packaging container, and any of a label and an electronic tag detachably connected to the packaging container and including an electrical code set for electrical authentication upon removal of any of the label and the electronic tag from the packaging container and being affixed to a device associated with the packaging container, wherein the electrical authentication is to validate the packaging container and the device as original equipment manufacturer components. Any of the label and the packaging container is altered upon removal of the label from the packaging container.

Authentication of devices by indicators on device packaging

An example method comprises setting a mixture of a plurality of print supplies of a print device to use for a process black print based on a plurality of supply levels corresponding to the plurality of print supplies. The example method further comprises initiating execution of the process black print of a print job by the print device using the set mixture of the plurality of print supply as overlapping colorant with the black print supply of the print device.

Setting print supplies for process black print based on supply levels

An example method comprises identifying a plurality of supply levels corresponding to a plurality of print supplies of a print device, and adjusting a color for a region of a print job for the print device based on the plurality of supply levels. The method further comprises initiating execution of the print job using the adjusted color for the region.

Adjusting colors based on supply levels of print supplies

A cartridge including a carrier storing an authenticity verification code readable by a scan device other than a host device and an auto-destruct feature to render the authenticity verification code unreadable at installation.

Cartridge comprising an auto-destruct feature

A cartridge including an interconnect circuit to communicate with a host device, a carrier storing an authenticity verification code readable by a scan device other than the host device, and an auto-destruct feature to render the authenticity verification code unreadable when installing the cartridge in the host device.

A toner cartridge packaging having a non-planar top surface is disclosed.

Toner cartridge packaging

An image forming system includes at least one toner cartridge, an image forming unit, and a cartridge life determination module. The toner cartridge may include toner and at least one component. The image forming unit may selectively form an image in one of a low coverage mode and a high coverage mode such that a greater amount of the toner is used in the high coverage mode than the low coverage mode in a formation of the respective image. The cartridge life determination module may determine an amount of remaining life of the toner, an amount of remaining life of the at least one component, and an effective amount of remaining life of the at least one toner cartridge based on the amount of remaining life of the toner and the amount of remaining life of the at least one component.

Determination of effective amount of remaining life of toner cartridge

A method for providing a message on a replaceable printing component of a printing device includes detecting a trigger event, retrieving a message from a memory associated with the replaceable printing component in response to the trigger event, and forming the message on an imaging member of the replaceable printing component, wherein the trigger event includes an end of a print job, and wherein the message remains on the imaging member after completion of the print job.

System and method for providing a message on a replaceable printing component

A consumable printing component for use in a printing device includes an imaging member and a memory storing message data. In response to a trigger event, a message is formed on the imaging member at the end of a print job such that the message remains on the imaging member.

System and method for providing messages on a printing component

A cartridge for a printing device includes first and second portions coupled to one another and capable of moving relative to each other, one or more rollers situated at the first portion, a photoconductor situated at the second portion, and a lock mechanism. The rollers are in contact with the photoconductor in a first position of the first and the second portions. The lock mechanism maintains the first and the second portions in a second position in which the rollers are separated from the photoconductor.
