The application relates to the field of print imaging, in particular to a repair method and repair chip for a regenerative ink cartridge, and a regenerative ink cartridge. The repair chip does not need to monitor all lines of a printer and only needs to monitor an enable line, a data line and 0n1 auxiliary lines of the printer, so that the number of pads, electrically connected with the printer, of an original chip is reduced, the welding difficulty and workload in the ink cartridge regeneration process are lowered accordingly, and the risk of ink cartridge scraping in the repair process is lowered from the source.

A manufacturing method of a cartridge, the cartridge being attachable to an apparatus main body of an image forming apparatus, the cartridge including a first member and a second member, the first member including a receiving surface and a retaining portion, and the second member including a contact surface in contact with the receiving surface. In the manufacturing method, the first member and the second member are held so that the contact surface covers the retaining portion and so that the contact surface and the receiving surface are in contact with each other and joined by ultrasonic spot welding so that a recess recessed towards the retaining portion is formed in the second member and so that at least part of a fused portion of the first member and the second member enters the retaining portion.

The present disclosure features an image forming apparatus having a first developing unit having a first developing roller; and a first toner supply unit configured to supply toner to the first developing unit, the first toner supply unit having: a first container configured to accommodate the toner therein, the first container having a first inlet opening through which the toner is received in the first container and a first outlet opening through which the toner in the first container is discharged; a first lid configured to close the first inlet opening; and a first shutter configured to open the first outlet opening when the first lid closes the first inlet opening, and to close the first outlet opening when the first lid opens the first inlet opening.

A method of converting a CMYK color toner printer to a CMYX color toner printer for under print printing in a single pass, comprising the steps: providing a color toner printer with four toner printing cartridges: a cyan toner printing cartridge, a magenta toner printing cartridge, a yellow toner printing cartridge, and a black toner printing cartridge; wherein the black toner printing cartridge is in a first toner cartridge position; removing the back toner printing cartridge from the first toner cartridge position; providing a non-standard toner printing cartridge; installing the non-standard toner printing cartridge into the first toner cartridge position; providing a raster image processor software; wherein the raster image processor software is configured to remap the four toner printing cartridges of the color toner printer and allows the color toner printer to print a layer of non-standard toner under an image in a single pass; and wherein the image is printed from at least one of a cyan toner, a yellow toner, and a magenta toner.

A method of converting a standard CMYK color toner printer to a CMYK or CMYW sublimation color toner printer. Providing a standard CMYK color toner printer, comprising four toner printing cartridges: a cyan toner printing cartridge, a magenta toner printing cartridge, a yellow toner printing cartridge, and a black toner printing cartridge. Removing the four toner printing cartridges, such that four empty toner cartridge slots are created. Providing four sublimation toner printing cartridges: a cyan sublimation toner printing cartridge, a magenta sublimation toner printing cartridge, a yellow sublimation toner printing cartridge, and a black sublimation toner printing cartridge, or a white sublimation toner printer cartridge. Installing the four sublimation toner printing cartridges into the four empty toner cartridge slots.

A toner cartridge disassembly machine for at least partially disassembling a toner cartridge. The toner cartridge includes a toner hopper and a waste hopper coupled to the toner hopper via a first pin and a second pin. The first pin is removably coupled within a first connection joint and the second pin is removably coupled within a second connection joint. The disassembly machine includes a base, a docking station supported by the base and capable of receiving the toner cartridge, and a carrier frame movably coupled to the base. The disassembly machine further includes a pin removal arm supported by the carrier frame. The pin removal is movable into a position between the first connection joint and the second connection joint. The pin removal arm includes a first push-out pin configured to interact with the first pin and a second push-out pin configured to interact with the second pin.
