Description
Technical field
The present invention relates to a kind of print cartridge design and manufacture method and application specific electronic module of working, relate in particular to a kind of intelligent ink cartridge design and manufacture method and application specific electronic module that subscriber-related ink user mode can be provided with ink-jet printer or jet graph plotter.
Background technology
At present, in printing equipments such as printer that uses intelligent ink cartridge or jet graph plotter, print cartridge inside is provided with electronic module, and this electronic module adopts passive memory usually, this passive memory generally adopts serial EEPROMs more under the situation of considering manufacturing cost.The storage of this serial storage is also stored rewritable service data as fixed datas such as manufacturer's name, date of manufacture, ink type, capacity, print cartridge models, as the first time installed date, print cartridge ink inside surplus or the like.For example, the EPSON ink-cases of printers that generally uses at present.
For the data of electronic module in this intelligent ink cartridge, printer can read according to instruction under situations such as print cartridge installation, printer power supply startup.And for the more new data of ink remaining amount usually at the printer deenergization or when replacing print cartridge, can be write back electronic module.Under normal conditions, the passive memory EEPROM in this intelligent ink cartridge only stores the more new data from printer, and is controlled the renewal of ink capacity by printer local side IC.
For example, in Chinese CN1257007A patent application document, a kind of intelligent ink cartridge is disclosed, the EEPROM that adopts one 8 is as the storage medium of ink remaining amount in the print cartridge, it is by being arranged on this machine of printer one side to data write in the print cartridge EEPROM, and perhaps IC on this machine of printer one side and the ink-cases of printers balladeur train and memory control carries out by being arranged on.This use passive memory is as the intelligent ink cartridge of electronic module, hardware configuration mainly is divided into each print cartridge and has stand-alone interface and multiple-limb common bus structure, is connected on the electronic module and the bus between the printer of print cartridge more than a print cartridge in the multiple-limb common bus structure.Respectively as shown in Figures 1 to 4.The hardware configuration that should be noted that Fig. 1 is the same to the print cartridge of different color.Can be for the print cartridge that Fig. 2 is connected on the common bus more than two.
In Fig. 1 to Fig. 4, the data transfer between printer and the print cartridge is by printer control and initialization.When opening printer power supply or print cartridge and be installed to printer, data are read from print cartridge.When disconnecting printer power supply, removing print cartridge or after read operation, the first time of the new print cartridge of mark, data were write into print cartridge when using.To the hardware configuration of independent control, the data communication between printer and each print cartridge can take place simultaneously.For the multiple-limb common bus structure, each print cartridge is visited in printer addressing successively (address packet is contained in the read/write instruction).
Usually, the serial data of reading from print cartridge is longer than the serial data that writes.This is because writing into data in the print cartridge only is variable quantity of ink, installed date or the like, yet the data of reading comprise such as print cartridge code and type, capacity, fixed datas such as manufacturer and date of manufacture.
The typical agreement of carrying out data communication between the print cartridge of independent control structure and the printer as shown in Figure 3.Wherein, the read cycle (read/write=0), data flow direction is from the print cartridge to the printer.Write cycle time (read/write=1), data flow direction is from the printer to the print cartridge.
The typical agreement of carrying out data communication between the print cartridge of multiple-limb common bus structure and the printer as shown in Figure 4.
For example, can use 4 public codings.Wherein, 3 are used for to addressing up to 8 print cartridges, and 1 is used for determining read or write.Should be noted that the read operation that can increase behind the write cycle time guarantees that the data of writing into print cartridge correctly store.
Print cartridge ink capacity commonly used at present is constant substantially, and capacity is all less, and the print cartridge so printer user has to often change is time-consuming wasted ink and frequently change print cartridge, and the waste resource.But, because the more new data of existing print cartridge electronic module is all controlled by this machine of printer, in order to satisfy the use of the existing printer of user, production firm just must adopt the electronic module identical with existing printer design, and some compatible print cartridge production firms also just can not produce the intelligent ink cartridge with higher ink capacity like this.Because being the paper type of existing printer setup when packing print cartridge into and the number of printing, the indication of print cartridge ink inside surplus calculates judgement again, existing printer shows that ink exhausts often in actual use, and in fact the ink in the print cartridge also remains much, this often makes ink in the print cartridge not be fully used and has just been abandoned by the user, the print cartridge ink capacity is little, just have to frequently change print cartridge, thereby cause the wasting of resources to a certain extent.Realizing the print cartridge of the applicable different production units of a kind of printer and use compatible ink, and improve the utilization factor of print cartridge ink, is that the current printer user generally wishes the technical matters that solves.

In Fig. 1-Fig. 4, prior art fully discloses a kind of technical scheme of intelligent ink cartridge, but it only is provided with an EEPROM on print cartridge, and to the access control of the print cartridge exhausted amount of ink data IC control by ink-jet printer one side.
In Fig. 5 to Fig. 9, a kind of novel intelligent ink cartridge of the present invention's design, the microcontroller MCU that will have built-in EEPROM increases the maximum ink capacity of print cartridge as passive serial EEPROM in the electronic module replacement prior art scheme.
In Fig. 5, intelligent ink cartridge of the present invention is made up of box body 1 that has ink and electronic module 2, and wherein, electronic module 2 is one to be built-in with the microcontroller MCU of EEPROM.In Fig. 6, for the print cartridge of independent control structure and the data communication between the printer, the electronic module 2 of intelligent ink cartridge of the present invention is to adopt the communication protocol identical with existing technical scheme with data communication interface between the existing ink-jet printer.Equally, in Fig. 7, for the print cartridge of many common bus structure and the data communication between the printer, the electronic module 2 of intelligent ink cartridge of the present invention also is to adopt the communication protocol identical with existing technical scheme with data communication interface between the existing ink-jet printer.
In Fig. 8, the electronic module 2 of intelligent ink cartridge of the present invention has adopted the microcontroller MCU of a special use, and it comprises hardware configuration and the Control Software two parts that are solidificated in the hardware configuration.Wherein, hardware components is CMOS 8 8-digit microcontroller MCU that adopt risc architecture, this microcontroller MCU is by the arithmetical unit 21 that connects by one 8 bit data bus modes, 22,32 * 8 general-purpose registers 23 of eeprom memory, interrupt location 24, serial peripheral interface unit 25,8 bit timers 26, analog comparator, 6 the I/O lead-foot-lines 28 that store print cartridge identifying information and ink remaining amount data, an and flash memory 29, flash memory 29 links to each other with general-purpose register 23, and general-purpose register 23 is connected with arithmetical unit 21.Wherein, software section comprises the program that is used to control ink remaining amount data operation and read-write, and this program is cured in the flash memory 29.By the control method that this software is implemented, following several embodiment is arranged.According to the communication protocol between hardware configuration and printer and the print cartridge, the present invention can realize by several different modes.
The variation of supposing relevant quantity of ink is represented (i.e. the new print cartridge of 0% expression, 100% expression empty cartridge) with the consumption of ink percent, and when printer outage and print cartridge are removed, printer will upgrade the quantity of ink data so.
Embodiment one
In Figure 10, shown the FB(flow block) of this scheme.In the present embodiment, for increasing ink capacity x%, the simplest method is:
Step 100 comprises the steps:
When opening power or print cartridge are installed to inkjet-printing device and move on to the normal position, send one first register of described microcontroller to being stored in consumption of ink rate data among the EEPROM, its consumption of ink rate is temp1;
After receiving the control signal of inkjet-printing device, described consumption of ink rate is stored to described inkjet-printing device one side from described first register transfer;
After finishing print job, upgrade the consumption of ink rate;
When inkjet-printing device outage or mobile print cartridge hold the storehouse to the installation site, will store into second register of described microcontroller from the renewal consumption of ink rate that inkjet-printing device one sidelights on are gone into print cartridge, its consumption of ink rate is temp2;
Step 101, the consumption of ink percent temp1 of storage stored the result into temp3 before the renewal consumption of ink percent temp2 that writes into print cartridge when printer cuts off the power supply deducted and upgrades;
Step 102, with the temp3=temp2-temp1 value that obtains in the step 101 divided by (1+x%);
Step 103 is the value temp1 that obtains in the step 101 and the consumption of ink percent temp3 addition of upgrading preceding storage, temp1=temp3+temp1;
Step 104 stores the value temp1 that obtains in the step 103 into EEPROM;
Step 105, the output of the value temp1 that utilizes in the step 104 storage data read cycle during as next printer opening power.
But, if when power supply opening, write into the value of print cartridge when value that printer is relatively read from print cartridge and last time printer outage, and when they are inconsistent, just start the cleaning operation of printhead, this kind scheme needs a certain amount of consumption of ink rate to be used for this printhead to clean so.If this consumption of ink rate of cleaning printhead has surpassed ratio increment discussed above, just can not use this kind scheme.
Embodiment two
For overcoming the design limitation among the embodiment one, in Figure 11, implementation step is improved as follows:
Step 201 uses software mark (adj) among the EEPROM be stored in the print cartridge electronic module to identify whether adjusted consumption of ink rate of microcontroller, adjusts with initial value ' 0 ' expression;
During printer power supply is opened, receive from the power supply signal of printer or when print cartridge is installed, with the consumption of ink rate transfer register reg1 that is stored among the EEPROM;
According to the control of printer, when printer power supply is opened, immediately the consumption of ink rate is sent to printer from reg1;
Printer is carried out print out task;
When printer outage or replacement print cartridge, the consumption of ink rate of writing into the print cartridge electronic module from printer is stored into reg1.
Step 203 by the software mark adj described in the read step 201, is checked whether adjusted (whether equaling 0 as judging adj) of consumption of ink percent;
Step 206 finishes.
Certainly, the present embodiment also has another possibility, and as the implementation step FB(flow block) as shown among Figure 11 A, implementation step is as follows:
Step 211 uses application state mark adj among the EEPROM be stored in the print cartridge electronic module to identify whether adjusted consumption of ink rate of microcontroller, adjusts with initial value ' 0 ' expression;
Step 212 when printer cuts off the power supply, as the common consumption of ink percent of storage update, and will be stored in consumption of ink rate transfer register reg1 among the EEPROM;
Step 213, in printer next time during switch power supply, if this consumption of ink percent reg1 surpasses predetermined value y (as 50%), wherein, y is greater than (x+a) %, and printer is during deenergization, the status indication adj described in the determining step 211; Otherwise to step 216;
Step 214, if the status indication in the step 213 is ' 0 ', then the consumption of ink percent is deducted (x+a) %, and status indication is changed into ' 1 ' indicate that the consumption of ink rate is adjusted, wherein, x% is the target increment of ink capacity, and a% is the additional consumption that causes owing to additional printhead cleaning operation; Otherwise up to step 216;
Step 215 is used the output of print cartridge read cycle when adjusted consumption of ink fraction values reg1 is as the printer opening power in the step 214, arrives step 217 then;
Step 216, the output of print cartridge read cycle when directly using the consumption of ink percent reg1 that from EEPROM, reads as the printer opening power;
Step 217 finishes.
But if behind the consumption of ink rate write cycle time when printer cuts off the power supply, printer has started another read cycle again to be checked, and if the different just lockings with the value that writes of the value of reading, so this scheme is inapplicable.
Embodiment three
In order to overcome the limitation of embodiment two, the read cycle when read cycle of carrying out immediately behind the write cycle time when the present invention adopts another kind of method to distinguish the printer outage and printer opening power.
Direct supply (V when usually, printer cuts off the power supply by the printer to the print cartridge electronic module immediately following the inspection read cycle behind the write cycle time
Cc) interval of a few tens of milliseconds arranged with the write cycle time of front in time.And the read cycle during the printer opening power, its direct supply (V
Cc) in several seconds or more time, turn off usually.
Like this, the R-C circuit with about 1 second time constant that is connected to input port (calling TP1 in the following text) will provide the information that needs, and distinguish read cycle and the normal read cycle detected.This can pass through at each V
CcCycle begins to read TP1 and realizes.For detecting the read cycle, sampling TP1 is ' 1 ', and for the normal read cycle, sampling TP1 is ' 0 '.Foregoing circuit as shown in Figure 9.
As shown in figure 12, further describe realization another implementation step of the present invention below:
Step 301 uses software mark adj among the EEPROM be stored in the print cartridge electronic module to identify whether adjusted consumption of ink rate of microcontroller, adjusts with initial value ' 0 ' expression;
Step 302 is when printer cuts off the power supply, as the consumption of ink percent of common storage update;
Step 303 when printer power supply is opened next time, reads input port TP1, if TP1 is ' 1 ' then to step 307, if be ' 0 ' then arrive step 304;
Step 306 is used the output of print cartridge read cycle when adjusted consumption of ink fraction values is as the printer opening power in the step 305, arrives step 308 then;
Step 308 finishes.
Above-mentioned implementation method is carried out by computer program means, and this program Solidification is in the electronic module 2 of the intelligent ink cartridge of the present invention's design, and this electronic module 2 has replaced passive serial in the prior art scheme
Increase the maximum ink capacity of print cartridge.Can only control this shortcoming by printer just because of the access that the present invention is directed to the data of print cartridge ink inside surplus in the prior art, adopt a special-purpose microcontroller to come the access of print cartridge ink inside surplus data is controlled, thereby the print cartridge of designing higher ink capacity is achieved.
