Fig. 6 is the schematic block diagram for illustrating some components according to exemplary printer box 600.In this example, it beats Print machine box 600 includes the security parameter engine 660 for reducing parameter 662 for storing sub-image.Printer box 600 can be for depositing Storage includes any kind of box of the deposition materials of charged particle.Exemplary deposition material may include ink, toner, plastics, Polymer, granulated metal, alloy etc..In one example, it includes to be used by ink-jet printer that printer box 600, which can be, The print cartridge of liquid ink.In another example, printer box 600 can be the dry toner comprising being used by laser printer The toner Cartridge of powder.In another example, print cartridge 600 can be three-dimensional box so that print cartridge 600 can be used for three-dimensional Printing.

In this example, security parameter engine 660 can be any combination of hardware and program for implement engine function. In this example, security parameter engine 660 can be disposed on the outer surface of print cartridge 600.In some instances, security parameter Engine 660 can be removably coupled to the outer surface of print cartridge 600.In this example, the security parameter engine 660 of Fig. 6 can be with Respectively including at least the function and/or hardware of the memory 460 of Fig. 4 or the memory 560 of Fig. 5.For example, security parameter engine 660 may include the memory for reducing parameter 662 for storing sub-image.

In this example, print cartridge 600 can provide sub-image reduction parameter 662 to the imaging device for being coupled to print cartridge 600. In this example, sub-image, which reduces parameter 662, can indicate the photoconductor to be applied to the imaging device for being coupled to print cartridge 600 The duration of written pattern, the number of written pattern, the amplitude of written pattern and written pattern power level at least One.In this example, imaging device can reduce parameter 662 according to sub-image and pattern is written to the photoconductor of imaging device. In this example, sub-image reduces parameter 662 and can be changed according to the box use information of print cartridge 600.In such an example, coupling Box use information can be provided to print cartridge 600 by the imaging device for being bonded to print cartridge 600.In other examples, print cartridge 600 It may include the photoconductor for monitoring imaging device and the print cartridge 600 for determining box use information or coupled Imaging device any other component hardware component and/or program.In this example, print cartridge 600 may include for changing Become the process resource that sub-image reduces parameter 662.In other examples, be coupled to print cartridge 600 imaging device can change it is latent As reducing parameter 662.

In some instances, print cartridge includes the security parameter engine for reducing parameter for storing sub-image, and sub-image reduces ginseng Number is at least indicating the duration of the pattern to be written to light-sensitive element to cover by image remaining on light-sensitive element Case is formed by potential pattern.In some instances, sub-image reduces the power level that parameter further comprises pattern.
