501, print cartridge control unit receives the light emitting control instruction from imaging equipment body;
502, the instruction that the identification of print cartridge control unit receives is that light lights instruction or light extinguishes instruction;
Wherein, print cartridge control unit identifies that this instruction is that light lights instruction or light extinguishes instruction according to the light control information in the light emitting control instruction in aforementioned table 1.
If it is that light lights instruction that print cartridge control unit recognizes described light emitting control instruction, then continue to perform 503-504; If it is that light extinguishes instruction that print cartridge control unit recognizes described light emitting control instruction, then continue to perform 505-506.
503, print cartridge control unit starts light delay timing;
Print cartridge control unit is that light lights instruction recognizing described light emitting control instruction, can not control luminous unit immediately luminous, but the luminous cell delay of control is luminous, so the delay timing that starts light.
504, print cartridge control unit is when monitoring the first delay gate limit value that the timing value lighting delay timing reaches default, controls described luminous unit luminous;
Wherein, the present embodiment, by the time of lag of luminous for the control of print cartridge control unit cell delay luminescence, is called the first delay gate limit value, and this first delay gate limit value was less than for the first period and was greater than for the 2nd period. Described first period is that print cartridge to be detected is carried out just timed interval to stage position detection by imaging equipment body, it is possible to represent with T1; Described 2nd period is the timed interval that print cartridge to be detected is carried out adjacent smooth detecting stage by imaging equipment body, it is possible to represent with T2. In the present embodiment, the first delay gate limit value was greater than for the 2nd period T2, and was less than for the first period T1.
In the present embodiment, described first delay gate limit value design is met condition as above, namely it was greater than for the 2nd period T2 and it was less than for the first period T1, it is based on following consideration: owing to the first delay gate limit value was greater than for the 2nd period T2, then being equivalent within the period carrying out adjacent light detection, luminous unit is not luminous due to delay; Simultaneously, owing to the first delay gate limit value was less than for the first period T1, then be equivalent within the period just position detected, the fluorescent lifetime (t1 represents the first delay gate limit value) of length when also at least having T1-t1 after postponing certain time, for detection, such that it is able to ensure that light quantity when just being detected position must be greater than light quantity when adjacent light detects.
In addition, the first delay gate limit value t1 that received light is lighted instruction delay setting by print cartridge just controls luminous unit luminescence, if time of lag does not reach t1, just receive light and extinguish instruction, then directly control not luminous, if time of lag has reached t1, do not receive light and extinguish instruction, then control luminescence.
505, print cartridge control unit starts and extinguishes delay timing;
Wherein, starting light described in the present embodiment postpones timing or extinguishes to postpone timing, it is possible to be initiating switchup, it is also possible to be restart after resetting for the timing register started.
506, print cartridge control unit is when monitoring the described timing value extinguishing delay timing and reach preset time period, controls described luminous unit and extinguishes;
Wherein, described preset time period was less than for the 3rd period; 3rd period T3 referred to the timed interval that the light that the extinguishing instruction of current light and next article send is lighted between instruction, was also the equal of just to the timed interval between stage position detection with adjacent smooth detecting stage.
In the present embodiment, received light is extinguished instruction and postpones described preset time period by print cartridge, just the luminous unit of control stops luminous, owing to described preset time period was less than for the 3rd period T3, after being then equivalent to the luminescence of the length when receiving light and extinguish instruction and luminous unit also maintains preset time period, the luminous unit of control stops luminous again, the stopping fluorescent lifetime of length when can also ensure there is T3-preset time period, so can ensure that adjacent smooth detecting stage is not luminous. The preset time period of the present embodiment is the 2nd delay gate limit value t2.
Specifically, the selection of preset time period is relevant to optical receiver sensitivity, and the sensitivity of optical receiver is more high, then preset time period should select smaller value; The sensitivity of optical receiver is more low, then preset time period can select slightly big value, but, no matter how to select, it must meet the preset time period < condition of T3. That is, if when delay certain time extinguishes light again, whether optical receiver can identify luminous unit has been extinguished relevant to the time response degree of optical receiver Received signal strength; If transfer is very fast, reaction is very fast, then just arrange shorter time of lag; If transfer is slow, reaction is slow, then can arrange longer comparatively speaking time of lag.
The light emitting control mode of print cartridge may have multiple, such as, carry out just being detected position and when detecting with adjacent light, corresponding print cartridge successively transmission light is lighted instruction and light extinguishing instruction, control this print cartridge luminous unit luminous regular hour, and each print cartridge do not distinguish light light instruction and light to extinguish instruction be for carrying out just to position detection or the detection of adjacent light; Or, it is also possible to position detection and the light emitting control instruction of adjacent smooth detecting stage just carried out merging treatment by certain print cartridge. In different light emitting control modes, the dividing mode of above-mentioned the first period, the 2nd period and the 3rd period is distinguished to some extent; Two kinds of such as following optional modes:
A kind of optional mode is, aligns and the period of position detection and the detection of adjacent light independently sends paired light lights instruction and light extinguishing instruction controls, controls print cartridge and move to just to position in light emitting control process. Then in the present embodiment, above-mentioned first period T1 is when just being detected position of print cartridge to be detected, and light lights instruction and light extinguishes the timed interval between instruction; 2nd period T2, when being then the adjacent light detection of above-mentioned print cartridge to be detected, light lighted instruction and light extinguishes the timed interval between instruction; 3rd period T3 was then just to the timed interval between stage position detection with adjacent smooth detecting stage, such as, just the light extinguishing instruction of stage position detection (adjacent smooth detecting stage) is lighted the timed interval between instruction with the light of adjacent smooth detecting stage (just to stage position detection). In addition, owing to imaging equipment body is independent in the light emitting control instruction just detected position and adjacent light detects for print cartridge to be detected, then the sequencing with the detection of adjacent light that just detected position of each print cartridge to be detected is not limit.
Another kind of optional mode is, if certain print cartridge needs luminous as the adjacent print cartridge of other print cartridges, luminous as just position being detected of print cartridge to be detected again, and above-mentioned twice light emitting control is continuously, then can only send one group of light and light instruction and light extinguishing instruction, make this print cartridge luminous all the time, be namely equivalent to just to the light emitting control instruction folding of stage position detection with adjacent smooth detecting stage. During this period, length is at least the first period T1 and the 2nd period T2 sum. For this kind of situation, above-mentioned first period T1 refers to and receives just light quantity to position detection to optical receiver from light lights instruction, and the 2nd period T2 referred to extinguishes instruction to light from the light quantity that optical receiver receives the detection of adjacent light. Or, above-mentioned 2nd period T2 refers to and receives just light quantity to position detection to optical receiver from light lights instruction, and the first period T1 referred to extinguishes instruction to light from the light quantity that optical receiver receives the detection of adjacent light. In addition, if print cartridge to be detected just to position detection with as the light emitting control instruction folding of adjacent light luminescence, then the scheme of the present embodiment is applicable to the situation that the detection of adjacent light performs after or before position is detected.
In the present embodiment, presetting extinguishing delay timing is the 2nd delay gate limit value, and preset time period is the 2nd delay gate limit value.
In addition, each print cartridge control unit configures the first delay gate limit value t1 and the concrete value of the 2nd delay gate limit value t2 preferably set as the first period corresponding during print cartridge to be detected, the 2nd period and the 3rd period according to self. And, owing to an imaging equipment can install multiple print cartridge, then different print cartridge may be identical or different from each other as the first period corresponding during print cartridge to be detected, and the 2nd period of correspondence also may be identical or different from each other, and the 3rd corresponding period also may be identical or differing from each other. If identical situation, then the first delay gate limit value that each print cartridge control unit configures the 2nd period that to be preferably greater than in described imaging equipment maximum, and it is less than the first minimum period; And the 2nd delay gate limit value configured preferably is less than the 3rd minimum period. If when different, then the first delay gate limit value that each print cartridge control unit configures meets above-mentioned " being greater than for the 2nd period, be less than for the first period ", the 2nd delay gate limit value meets the regulation of above-mentioned " being less than for the 3rd period ". Further, the delay gate limit value that different print cartridge control unit configures can also be same to each other or different to each other.
After the present embodiment adopts such scheme, the optical receiver detected result in imaging equipment body side is, within the T1 period, still can receive light, have the first light quantity, detects just that position detection is correct accordingly; Within the T2 period, can not receiving light, light quantity is zero, must be less than the first light quantity, also can judge that the detection of adjacent light is correct accordingly. It can thus be seen that the technical scheme that the embodiment of the present invention provides, imaging equipment specific position testing requirement can either be met, the False Rate defect that the manufacture error of the luminous unit of print cartridge causes can be overcome again. Further, imaging equipment body may be sold and be in use, and adopts the program without the need to being changed by existing a large amount of imaging equipment body, only needs to be improved by easily-consumed products print cartridge, is thus easy to promote realizing.
For more clearly the print cartridge light-emitting control method that the present embodiment provides being introduced, it is that above-mentioned control method is described by example based on Fig. 6 a and 6b below.
In the present embodiment, four print cartridges loading different colours ink, there is identical appearance, such as BK print cartridge, C print cartridge, M print cartridge, Y print cartridge, it is loaded on printer (imaging equipment), and print cartridge is equipped with LED (luminous unit), and pass through the observation to print cartridge position testing process in imaging equipment body and measurement, it is possible to the movement and the detection ordering that obtain the multiple print cartridges in the testing process of position are as follows:
MobileMobile
Mobile
Fig. 6 a is the print cartridge light-emitting control method of the present invention sequence of print cartridge in embodiment schematic diagram again, and four print cartridges move under the drive of word car 201; Known in conjunction with above-mentioned print cartridge sequence of motion, C print cartridge due to as BK print cartridge adjacent light detection with C print cartridge self as print cartridge to be detected just to position detection two stages be continuous print, so the present embodiment is with just to position combining data detection by the detection of adjacent light, only comprise a light and light instruction and light extinguishing instruction, i.e. a CON and COFF. Specifically, the type of detection that when each print cartridge above-mentioned carries out just position detection and adjacent light being detected, timed interval between each light emitting control instruction of sending of printer and this detection signal carry out is as shown in table 2. Wherein, timed interval ��, t represented the timed interval between an instruction and next instruction, if the timed interval between BKON and BKOFF is 800ms, type of detection N then represents that adjacent light detects, P represents and is just detected position, N+P then represents the merging comprising the detection of adjacent light and just being detected position, such as C print cartridge place.
Timed interval between table 2 light emitting control instruction and type of detection
In order to express easily, the light emitting control instruction hereafter sent for printer (imaging equipment) directly represents with " color ID+ light emitting control information ", representing that such as instruction BKON the luminous unit driving black ink box is luminous, instruction BKOFF represents that the luminous unit of control black ink box extinguishes.
According to the detection ordering of the �� t shown in table 2 and type of detection and above-mentioned print cartridge it will be seen that print cartridge is when carrying out just being detected position, the timed interval between the instruction that control LED is lighted and the instruction that control LED is extinguished is relatively big, is all greater than 300ms; And when carrying out the detection of adjacent light, it is less that light lights the timed interval between instruction and light extinguishing instruction, substantially about 100ms all it is less than, and each light extinguishes instruction and next light does not light the timed interval between instruction not etc., is substantially all not less than 7ms. For this reason, in this example, preferably, above-mentioned first delay gate limit value is set to 200ms, and the 2nd delay gate limit value is set to 3ms, so, when multiple print cartridge carries out above-mentioned testing process, just carrying out smoothly position detection part can be ensured, can avoid again carrying out adjacent light detection, even if thus ensureing LED (luminous unit) brightness is slightly weak, the normal print cartridge of function can also normally use.
Fig. 6 b is the print cartridge light-emitting control method of the present invention detection of BK print cartridge position in embodiment schematic diagram again. As shown in Figure 6 b, when printer sends BKON instruction, the print cartridge control unit of four print cartridges all starts light when this instruction being detected delay timing, until when the timing value lighting delay timing reaches the first delay gate limit value, it is luminous that the print cartridge control unit of four print cartridges all controls the LED on it. After the luminescence that luminous unit maintains for some time, printer sends BKOFF instruction, now the print cartridge control unit of four print cartridges all starts when this instruction being detected and extinguishes delay timing, then now the LED of four print cartridges still maintains luminous state, until when the timing value extinguishing time delay timing reaches the 2nd delay gate limit value, the print cartridge control unit of four print cartridges all controls the LED on it and extinguishes. Now, just stage position detection being completed of BK print cartridge. So analogizing, when printer sends each steering order as shown in table 2 successively, each print cartridge all performs according to such scheme.
In addition, in the present embodiment, when above-mentioned light postpone timing or extinguish postpone timing reach the first delay gate limit value or the 2nd delay gate limit value time, stopping above-mentioned lighting to postpone timing or extinguish postpone timing or postpone timing or extinguish to postpone timing and reset by above-mentioned lighting, the above-mentioned luminous unit of print cartridge control unit control is luminous or extinguishes. When lighting, according to stopping is above-mentioned, the mode postponing timing, then again receive at print cartridge control unit and first postpone timing or extinguish after delay timing resets to restart timing by above-mentioned lighting when light lights instruction or light extinguishing instruction. Light in the timing course postponing timing or extinguish after postponing timing startup when above-mentioned, when print cartridge control unit receives arbitrary light emitting control instruction, namely stop above-mentioned lighting postpone timing or extinguish time delay timing, and light after instruction or light extinguishes instruction again receiving light, postpone timing or extinguish postpone timing clearing or reset by above-mentioned lighting again, to restart beginning timing; Or, directly postpone timing or extinguish to postpone timing and reset or reset by above-mentioned lighting, so that it is lighted after instruction or light extinguish instruction and can directly start with timing again again receiving light.
Embodiment three
The difference of the present embodiment and embodiment two is, it is the 2nd delay gate limit value that the extinguishing preset of the present embodiment postpones timing, described preset time period is less than the 2nd delay gate limit value, and it was less than for the 3rd period, and the 2nd delay gate limit value value be greater than for the 3rd period, being less than for the first period T1, print cartridge control unit starts can automatically control luminous unit and extinguish after timing reaches described preset time period in above-mentioned extinguishing time delay timing.
Concrete, when print cartridge control unit recognize light emitting control instruction be light extinguish instruction time, start to extinguish and postpone timing; When the timing value that print cartridge control unit monitors above-mentioned extinguishing delay timing reaches described preset time period, the luminous unit of control extinguishes automatically; When the timing value that print cartridge control unit unit monitors above-mentioned extinguishing delay timing reaches the 2nd delay gate limit value, control above-mentioned luminous unit and stop luminous. And, above-mentioned extinguishing postpone timing timing course in, print cartridge control unit does not perform the light emitting control instruction received in this timing course, above-mentioned extinguishing postpone timing also without the need to stop or reset but proceed timing. All the other steps are identical with a upper embodiment, repeat no more.
For more clearly the print cartridge light emitting control scheme that the present embodiment provides being introduced, below based on Fig. 7, for BK print cartridge, above-mentioned control method is described.
Fig. 7 is the detection of the BK print cartridge position in print cartridge light-emitting control method embodiment of the present invention schematic diagram. As shown in Figure 7, when printer sends BKON instruction, the print cartridge control unit of four print cartridges all starts light delay timing, until lighting the timing value postponing timing when reaching the first delay gate limit value, it is luminous that the print cartridge control unit of four print cartridges all controls the LED on it. After the luminescence that luminous unit maintains for some time, printer sends BKOFF instruction, now the print cartridge control unit of four print cartridges all starts and extinguishes delay timing, then now the LED of four print cartridges still maintains luminous state, until when the timing value extinguishing time delay timing reaches particular value and preset time period, the print cartridge control unit of four print cartridges automatically controls the LED on it and extinguishes, and extinguishes time delay timing and proceeds timing. When the timing extinguishing time delay timing reaches the 2nd delay gate limit value, and when period does not receive new light emitting control instruction, the print cartridge control unit of four print cartridges again the LED of secondary control on it extinguish, namely four LED all maintain OFF state. Now, just stage position detection being completed of BK print cartridge. So analogizing, when printer sends each steering order as shown in table 2 successively, each print cartridge all performs according to such scheme.
In addition, identical with embodiment one, when above-mentioned light postpone timing or extinguish postpone timing reach the first delay gate limit value or the 2nd delay gate limit value time, stopping above-mentioned lighting to postpone timing or extinguish postpone timing or postpone timing or extinguish to postpone timing and reset by above-mentioned lighting, the above-mentioned luminous unit of print cartridge control unit control is luminous or extinguishes. But, above-mentioned light postpone timing or extinguish postpone timing timing during, if receiving new light emitting control instruction, print cartridge control unit does not perform above-mentioned new light emitting control instruction, also without the need to stopping timing and reset or clearing, until reaching default timing value, as stopped timing after the first delay gate limit value and the 2nd delay gate limit value again or directly reset or reset.
Embodiment four
Fig. 8 is the schematic flow sheet of the light-emitting control method embodiment again of print cartridge of the present invention, and the print cartridge control unit of the present embodiment specifically adopts and extinguishes the mode of instruction as timing starting point taking light; As shown in Figure 8, the method can comprise:
801, print cartridge control unit receives the light emitting control instruction from imaging equipment body;
802, the instruction that the identification of print cartridge control unit receives is that light lights instruction or light extinguishes instruction;
Wherein, print cartridge control unit identifies that this instruction is that light lights instruction or light extinguishes instruction according to the light control information in light emitting control instruction;
If it is that light lights instruction that print cartridge control unit recognizes described light emitting control instruction, then continue execution 803; If it is that light extinguishes instruction that print cartridge control unit recognizes described light emitting control instruction, then continue to perform 804-805.
803, print cartridge control unit determines whether to perform according to the reception number of times of light emitting control instruction;
If it is 1 that described light lights the occurrence number of instruction, then control described luminous unit luminous; If the occurrence number that described light lights instruction is greater than 1, does not then perform described light and light instruction.
804, the described luminous unit of print cartridge control unit control extinguishes, and starts timing simultaneously;
805, print cartridge control unit is when monitoring timing value and reach predetermined threshold value, performs in during timing last the light emitting control instruction received.
Wherein, described predetermined threshold value is greater than described 2nd period and the 3rd period sum, and is less than described first period and the 3rd period sum.
Owing to a printer can install multiple print cartridge, then different print cartridge may be identical or different from each other as the first period corresponding during print cartridge to be detected, and the 2nd period of correspondence is also possible identical or different from each other, the 3rd corresponding period also may be identical or differing from each other. If different situations, then the threshold value that each print cartridge control unit configures preferably is greater than in described imaging equipment the 2nd maximum period and the 3rd period sum, and is less than the first minimum period and the 3rd period sum. If when identical, then the threshold value that each print cartridge control unit configures meets the regulation of above-mentioned " being greater than the 2nd period and the 3rd period sum, be less than the first period and the 3rd period sum ". Further, the threshold value that different print cartridge control unit configures can also be same to each other or different to each other.
According to timed interval between each steering order in table 2 it will be seen that the first period of each print cartridge is not identical, but all it is greater than 300ms, 2nd period of each print cartridge is not identical yet, but all it is less than 100ms, and taking OFF instruction as node, the timed interval (i.e. the 3rd period) between each OFF instruction to next ON instruction is also different, roughly at 7ms 90.2ms, for this reason, in the present embodiment, according to above-mentioned value regulation, preferably, predetermined threshold value t is set to 195ms.
In addition, if print cartridge control unit receives the light that printer sends extinguishes instruction, then above-mentioned timing will reset or reset after timing again; If receiving the light that printer sends to light instruction, then do not perform above-mentioned instruction, do not stop timing yet.
The present embodiment is by adopting technique scheme, print cartridge control unit in adjacent smooth testing process can be made to carry out delay operation and cause luminous unit not luminous by control, the light quantity making adjacent smooth detecting stage is 0, it is less than just light quantity to stage position detection, thus ensures that each print cartridge can smoothly by above-mentioned position testing process.
Fig. 9 a-9d is the position detection schematic diagram of print cartridge light-emitting control method of the present invention BK/C/M/Y print cartridge in an embodiment again, referring to Fig. 9 a-9d, above-mentioned control method is resolved, wherein the direction of arrow shown in the A in figure represents the travel direction in print cartridge testing process (in following description, the example using ink-jet printer as imaging equipment).
As illustrated in fig. 9, printer sends the steering order of " BKON " first, and print cartridge control unit is when receiving this BKON instruction, first identify that this instruction is that light lights instruction according to light control information ON, and lighting instruction occurrence number due to light is 1, then now print cartridge control unit directly performs the steering order of above-mentioned BKON, and namely the print cartridge control unit of four print cartridges all controls LED luminescence. Then, after the LED of four print cartridges maintains for some time luminescence, printer sends " BKOFF " steering order, when print cartridge control unit receives this instruction, it is judged as that light extinguishes instruction, then the control unit of four print cartridges directly extinguishes LED, and starts to start timing.
As shown in figure 9b, foregoing, timing threshold value is 195ms, therefore known according to table 2, in timing course, printer sends CON instruction, after print cartridge control unit receives this instruction, is identified as light and lights instruction, and count on this light and light instruction and occurred 2 times, > 1, therefore do not perform above-mentioned steering order, proceed timing. When print cartridge control unit monitor above-mentioned timing value reach predetermined threshold value and 195ms time, stop timing, and the steering order that execution finally receives during timing, or say the prior instruction performing distance predetermined threshold value and receiving recently, namely CON instruction is performed, then now LED is driven to emit light, and is now just being detected position of C print cartridge. And C print cartridge was as the adjacent smooth detecting stage consumption past between aforementioned time delay of BK print cartridge. Equally, after print cartridge control unit receives COFF instruction, it extinguishes LED, and start timing, and, do not perform the BKON instruction received in timing course, and when receiving BKOFF instruction, stop timing and timing register is reset or resets, restart timing.
As shown in figures 9 c and 9d, principle same as described above, in the timing course after BKOFF, the MON instruction not performed to receive equally; When timing value reaches predetermined threshold value, then perform the MON instruction that it is front receiving, namely drive LED luminous. So analogizing, the detection mode of all the other print cartridges is also as above similar, does not repeat at this.
Seen from the above description, the present embodiment is taking " OFF instruction " as node, the light emitting control instruction not performing adjacent smooth detecting stage is operated by timing, thus make the luminous unit of adjacent smooth detecting stage not carry out luminescence, to ensure that print cartridge is at the luminous quantity that the luminous quantity of stage position detection is just always greater than adjacent smooth detecting stage, ensure passing through smoothly of print cartridge position testing process, avoid the situation that " print cartridge is loaded on correct position but to be considered to be loaded in wrong position " occurs.
The following situation of further instruction: owing to the luminous quantity of unit luminous on each print cartridge exists error, in the testing process of position print cartridge then may be caused just cause cannot by the problem of detection to the luminous quantity of stage position detection is not enough, now just need in just that the luminous unit of print cartridge multiple during stage position detection is simultaneously luminous or extinguishing, to guarantee that each print cartridge can smoothly by just to stage position detection (embodiment above also describes the situation that this kind of multiple print cartridge is simultaneously luminous or extinguishes).
Concrete, the light emitting control instruction of imaging equipment body comprises: print cartridge identifying information and light control information; The luminous unit of print cartridge is carried out light emitting control by the present embodiment, it is possible to be designed to only control the luminous unit luminescence of described print cartridge according to described light control information or extinguish.
In the present embodiment, multiple print cartridge is that conllinear connects, so arbitrary light emitting control instruction that imaging equipment body sends, each print cartridge can both receive, often receive a steering order, then luminous unit can be performed a secondary control according to above-mentioned print cartridge light-emitting control method by each print cartridge, thus ensures that multiple luminous unit by lighting simultaneously or is extinguished, to ensure each print cartridge smoothly by just to stage position detection. That is, luminous unit is only controlled by the print cartridge control unit of the present embodiment according to the light control information in light emitting control instruction, ignores the print cartridge identifying information in above-mentioned steering order.
Optionally, each print cartridge in the present embodiment is carrying out in the testing process of position, has at least two print cartridges and this print cartridge light simultaneously or extinguish, as long as can ensure that print cartridge is just can be by stage position detection; And in the present embodiment, the mode that bus connects between each print cartridge, both can have been adopted, it is possible to the mode adopting single line to connect, is not restricted this.
Such as, as shown in table 1, print cartridge identifying information in light emitting control instruction preferably includes at least two logical values, therefore the luminous unit controlling at least two print cartridges in the present embodiment in the following ways is simultaneously luminous: the logical value of part or all of position of print cartridge control unit by abandoning in above-mentioned print cartridge identifying information, and the logical value of residue position is contrasted with the logical value of corresponding position in the print cartridge identifying information of its place print cartridge, and determine that the above-mentioned print cartridge identifying information received is the print cartridge identifying information of place print cartridge, the print cartridge of two or more so just can be ensured to have to be lit simultaneously. if abandoning the logical value of whole position, then there is not the logical value of residue position, then now can think that light emitting control instruction is sent to all print cartridges. in this case, if when the first and second delay gate limit values that multiple print cartridge control unit adopts are all identical, just there will be the situation that the luminous unit of multiple print cartridge is lighted or extinguished simultaneously.
Illustrate as follows: assume as print cartridge identifying information corresponding to each print cartridge in equipment respectively: BK-000, C-100, M-010, Y-110, if abandoning last two logical values of above-mentioned each print cartridge identifying information, namely part logical value is equivalent to abandon, then now turn into BK-0, C-1, M-0, Y-1, the then now residue position of BK and M or claim that the logical value of corresponding position is identical with light emitting control instruction BKON is 0 (first " 0 " in " BK-000 " in the BKON instruction such as received, it is identical with BK-0, also it is identical with M-0), then now the print cartridge identifying information in BKON instruction will be identified as BK-0 and M-0, namely this instruction is for controlling BK and M, then BK and M print cartridge is lighted simultaneously, all the other print cartridges are not lit, if abandoning whole logical value, be namely equivalent to the print cartridge identifying information ignored in light emitting control instruction, only according to light emitting control information Control light from light source wherein.
In addition, in the present embodiment, the interface unit on print cartridge is contact, with printer contact pilotage, the electrical contact exchanging information, therefore above-mentioned logical value is received and dispatched by electrical contact form; And preferably, whether abandoning of above-mentioned logical value can be realized by the mode of the switching over of electrical contact or disconnection, such as, realize abandoning of this logical value when disconnecting, or, abandoning of this logical value can also set in advance.
After described timing starts, when described print cartridge control unit receives another light emitting control instruction, and when another light emitting control instruction described is identified as light extinguishing instruction, stops described timing, or described timing is resetted. Such as, it is BKON/OFF, CON/OFF, BKON/OFF that printer sends the order of instruction, and print cartridge control unit is when receiving first BKOFF instruction, starting to start timing, when it receives the 2nd BKOFF instruction, then above-mentioned timing register stops, or reset, then restart timing.
