Embodiment 1

[0058] In this embodiment, any one of the clock line CLK and the address line ADD can be omitted. The repair chip is equipped with enable contacts, data contacts and address contacts. The number of address contacts is the number of printer address lines minus one. Assume that the number of address lines of the printer is m, and the number of address contacts of the original chip is m. Repair the number of chip address contacts to be m-1. Such as image 3, the repair chip is provided with a storage device, a command judgment device and a data return device, the repair data is stored in the storage device, the data return device is electrically connected with the address contact, the data contact and the enable contact respectively, and the data return device is connected with the command judgment The device is electrically connected. The command judging device is provided with a command judging unit, and the command judging unit is electrically connected to m-1 address contac...

Embodiment 2

[0074] In this embodiment, clock lines and all address lines can be omitted, and only enable lines and data lines are used. The repair chip only sets enable contacts and data contacts. Such as Figure 7 , the repair chip is provided with a storage device, a command judging device, a data returning device and a timer. Repair data is stored in the storage device, and the repair data is used to make the information indicating the remaining ink volume of the ink cartridge not be 0. The data returning device includes a data sending device, a comparator and a counter.

[0075] The waste ink cartridges that need to be regenerated include the ink cartridge body and the original chip installed on the ink cartridge body. The repair chip is installed on the ink cartridge body, so that the enable contact of the repair chip is electrically connected with the enable contact of the original chip; the data contact of the repair chip is electrically connected with the data contact of the or...

Embodiment 3

[0089] In this embodiment, the clock line and one or more address lines can be omitted. Repair the chip to set the enable contact, data contact, and 2 address contacts. Such as Figure 11 , the repair chip is provided with a storage device, a command judging device, a data returning device and a timer. Repair data is stored in the storage device, and the repair data is used to make the information indicating the remaining ink volume of the ink cartridge not be 0.

[0090] The waste ink cartridges that need to be regenerated include the ink cartridge body and the original chip installed on the ink cartridge body. Install the repair chip on the ink cartridge body so that the enable contact of the repair chip is electrically connected to the enable contact of the original chip; the data contact of the repair chip is electrically connected to the data contact of the original chip, and the two addresses of the repair chip The contacts are electrically connected with any two addr...

Abstract

The invention relates to the field of printing imaging, in particular to a repair method and a repair chip of a regeneration ink box and the regeneration ink box. The repair chip does not need to monitor all lines of a printer and only needs to monitor an enabling line and a data line of the printer and 0-(n-1) assistance lines. Therefore the number of contacts electrically connected with the printer and an existing chip is decreased, the welding difficulty and workloads in the regeneration process of the ink box are reduced, and the risk that the ink box is scrapped in the repair process is lowered from the source. According to the characteristics of a communication protocol between the existing chip of the ink box and the printer, the repair chip judges the type of a command sent by the printer only according to the signal characteristics of a small number of lines, monitored by the chip, of the printer, determines data needing to be obtained by the printer only according to signals, monitored by the chip on the small number of printer lines when judging that the command sent by the printer is an effective data reading command, and returns the data to the printer through the data line of the printer.

Description

technical field [0001] The invention relates to the field of printing and imaging, in particular to a repair method for a regenerated ink cartridge, a repair chip and a regenerated ink cartridge. Background technique [0002] The existing printer ink cartridge chip includes enable contacts, data contacts, address contacts and clock contacts, which are respectively connected to the enable line, data line, address line and clock line of the printer, receive commands from the printer and respond , the related use and configuration information of the ink cartridge is stored in the ink cartridge chip. In order to prevent users from reusing ink cartridges that have run out of ink, original ink cartridge manufacturers adopt a method that cannot directly reset the ink cartridge usage information. For example, the storage unit uses fuse bits to record ink volume information. When the ink of the ink cartridge is exhausted, the storage unit on the ink cartridge will record the state i...
