The invention provides a serial number adjustment method and device. The method includes the steps that a current serial number switching mode of an imaging box is obtained; when the current serial number switching mode of the imaging box is an undetermined mode, whether a serial number sent to a printer is legal or not is judged; and when it is determined that the serial number sent to the printer is legal, the current serial number switching mode of the imaging box is switched into a locked mode from the undetermined mode, so that the currently used serial number of the imaging box is maintained unchanged. By means of the serial number adjustment method and device, a new imaging box can continue to be used after the imaging box is changed, judgment is not needed after the serial number is locked, compared with a manner that judgment is performed each time power-on is performed without locking, electricity is saved, and it is avoided that an error occurs when judgment is performed again.
Description
【Technical field】 [0001] The invention relates to the technical field of printing, in particular to a serial number adjustment method and a serial number adjustment device. 【Background technique】 [0002] At present, printers include inkjet printers and laser printers. Inkjet printers use imaging cartridges, which are loaded with ink, and laser printers use toner cartridges or toner cartridges, which are loaded with toner. These cartridges may be collectively referred to as imaging cartridges, and the toner and ink may be collectively referred to as recording materials. [0003] After the recording material of the imaging cartridge is consumed, the printer will memorize the serial number of the imaging cartridge, which is stored on the cartridge chip of the imaging cartridge. Since the imaging cartridges sold on the market are produced by many manufacturers, it is inevitable that the serial numbers will be the same. If the user replaces and installs a new imaging cartridge ...
