When follow-up printer powers on to consumable chip, error detection logic unit inspection is not damaged to the data of this consumable chip metering zone 1 for subsequent use, then error detection logic unit damages signal can not to the input of erroneous values counter unit, then the memory value of erroneous values counter can not add 1, point to logical gate erroneous values memory value remain 1, the metering zone for subsequent use of current use is still and points to corresponding metering zone 1 for subsequent use, consumable chip uses the data of this metering zone 1 for subsequent use and printer to carry out data communication, consumable chip can by printer identification, consumable container still can continue to use.
The mode that Fig. 9 remedies after reflecting the corrupted data to metering zone for subsequent use, but in print procedure, when corrupted data in a certain metering zone for subsequent use, if consumptive material use amount is still initial value in next metering zone for subsequent use used, then there will be the erroneous metrology of consumptive material use amount, the present embodiment adopts to upgrade and detects logical block to solve the problem, see Figure 10, when consumable chip and printer carry out data communication, upgrade the data difference detecting the real-time more current metering zone 1 for subsequent use of logical block and next metering zone 2 for subsequent use, when detecting that the metering zone for subsequent use 1 of current use is 10% than the consumption parameter difference of next spare area 2, then by control unit by the Data Update of metering zone 1 for subsequent use for current use in next metering zone 2 for subsequent use.With consumptive material surplus % data instance, second byte data of address 0X0E or address 0X11 is consumptive material surplus % data, and consumptive material printing amount % and consumptive material surplus % has following relation:
Consumptive material printing amount % data=1-consumptive material surplus % data
Or consumptive material surplus % data=1-consumptive material printing amount % data
The printer printing amount printed in current metering zone for subsequent use 1 is 10%, its decimal number of residue 90%(data hexadecimal data 5A is 90, i.e. consumptive material surplus 90%), and the printing amount that next metering zone 2 for subsequent use stores is 0%, namely residue 100%(upgrades front data, the same with the brand-new data of the metering zone for subsequent use 2 of Fig. 9, second byte data of address 0X0E or address 0X11 is hexadecimal number 64, its decimal system is 100, i.e. consumptive material surplus 100%), now upgrade and detect consumptive material surplus (100%) difference 10 % points that logical block detects consumptive material surplus (90%) metering zone 2 more for subsequent use than next of current metering zone for subsequent use 1, therefore upgrade detection logical block and carry a more new signal to control unit, after control unit receives this signal, by the data copy of current metering zone 1 for subsequent use to next metering zone for subsequent use 2 li, see the data of the metering zone for subsequent use 2 of Figure 10.Printer continues to print, current metering zone for subsequent use 1 continues metering, when printing to the data of metering zone 1 current for subsequent use of Figure 10, i.e. printing amount 11%, consumptive material surplus 89%(hexadecimal number 59), if now current metering zone for subsequent use 1 is because of accidental damage, then consumable chip will enable the data (90%) of next metering zone 2 for subsequent use, because damaging rear metering zone for subsequent use 2 as current metering zone, and than damaging the consumptive material surplus difference 90%-89%=1% of front metering zone 1 for subsequent use, be more or less the same with the consumptive material consumption of actual normal print after therefore remedying by the method.
By upper, adopt the consumable chip of the present embodiment, can in the impaired situation of data, realize remedying of data, and, due to upgrade detect logical block by control unit by the Data Update of current metering zone for subsequent use in next metering zone for subsequent use, make the variables such as consumptive material use amount, number of print pages and actual use amount basically identical, consumable container can continue to use, the data of carrying out communicating in consumable chip with printer also substantially accurately reflect actual consumption, ensure the normal work of consumable container and consumable chip thereof.
