REPAIR METHOD AND REPAIR CHIP FOR REMANUFACTURED INK CARTRIDGE, AND REMANUFACTURED INK CARTRIDGE

摘要

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 0∼n-1 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. The repair chip judges the type of a command sent by the printer according to the characteristic of a communication protocol between the original chip of the ink cartridge and the printer and the characteristics of signals on only few printer lines monitored by the repair chip, determines data needing to be required by the printer according to the signals on the few printer lines monitored by the repair chip when it is judged that the command sent by the printer is a valid data reading command, and returns the data to the printer through the data line of the printer.
