Fig. 6 a-6d is the position probing schematic diagram of the BK/C/M/Y print cartridge in the another embodiment of the utility model print cartridge light-emitting control method, referring to Fig. 6 a-6d, above-mentioned control method is resolved, wherein the direction of arrow shown in the A in figure represents the moving direction (in following description, with the example of ink-jet printer as imaging device) in the print cartridge testing process.

As shown in Fig. 6 a, printer sends the control instruction of " BK ON " first, and when the print cartridge control module receives this BK ON instruction, at first identifying this instruction according to light control information ON is that light is lighted instruction, and lighting the instruction occurrence number due to light is 1, this moment, the print cartridge control module was directly carried out the control instruction of above-mentioned BK ON, and namely all to control the LED lamp luminous for the print cartridge control module of four print cartridges.Then, the LED lamp of four print cartridges keep a period of time luminous after, printer sends " BK OFF " control instruction, when the print cartridge control module receives this instruction, it is judged as light and extinguishes instruction, and the control module of four print cartridges directly extinguishes the LED lamp, and begins to start timing.

As shown in Fig. 6 b, foregoing, the timing threshold value is 195ms, therefore according to table 2 as can be known, in timing course, printer sends C ON instruction, after the print cartridge control module receives this instruction, is identified as light and lights instruction, and counting on this light lights instruction and has occurred 2 times, 1, therefore do not carry out above-mentioned control instruction, proceed timing.When the print cartridge control module monitors above-mentioned clocking value and reaches predetermined threshold value and be 195ms, stop timing, and carry out the control instruction receive at last during timing, carry out in other words the last instruction of receiving recently apart from predetermined threshold value, namely carry out C ON instruction, this moment, the LED lamp was driven luminous, be this moment the C print cartridge over against position probing.And the C print cartridge consumes in the past between aforementioned time delay as the adjacent light detection-phase of BK print cartridge.Similarly, after the print cartridge control module received C OFF instruction, it extinguished the LED lamp, and the beginning timing, and, do not carry out the BK ON instruction that receives in timing course, and when receiving BK OFF instruction, stop timing and with the timer zero clearing or reset, restart timing.

As shown in Fig. 6 c and 6d, principle same as described above in timing course after BK OFF, is not carried out the M ON instruction that receives equally; When clocking value reaches predetermined threshold value, carry out it in the M ON instruction that front receives, namely the driving LED lamp is luminous.So analogize, the detection mode of all the other print cartridges is also as above similar, does not do at this and gives unnecessary details.

Seen from the above description, the present embodiment is take " OFF instruction " as node, operate not carry out the light emitting control instruction of adjacent light detection-phase by timing, thereby it is luminous that adjacent light detection-phase luminescence unit is not carried out, to guarantee that print cartridge is over against the luminous quantity of stage position detection always greater than the luminous quantity of adjacent light detection-phase, guarantee passing through smoothly of print cartridge position probing process, avoid occurring the situation of " print cartridge is loaded in and but is considered to be loaded in wrong position on correct position ".

The light emitting control mode of print cartridge may have multiple, for example, carry out when position probing and adjacent light detect, corresponding print cartridge successively being sent that light is lighted instruction and light extinguishes instruction, control the luminous regular hour of this print cartridge luminescence unit, and each print cartridge is not distinguished light and is lighted instruction and light to extinguish instruction be used to carrying out over against position probing or adjacent light detects; Perhaps, also can merge processing to the light emitting control instruction over against position probing and adjacent light detection-phase of certain print cartridge.In different light emitting control modes, the dividing mode of the first above-mentioned period, the second period and the 3rd period is distinguished to some extent; Two kinds of following optional modes for example:

A kind of optional mode is, aligns the period that position probing and adjacent light are detected independently to send paired light and light instruction and light and extinguish instruction and control, and the control print cartridge moves to over against the position in the light emitting control process.In the present embodiment, above-mentioned the first period T1 be print cartridge to be detected over against position probing the time, light is lighted instruction and light and is extinguished time interval between instruction; The second period T2 is the adjacent light of above-mentioned print cartridge to be detected when detecting, and light is lighted instruction and light and extinguished time interval between instruction; The 3rd period T3 is over against the time interval between stage position detection and adjacent light detection-phase, such as, the light that extinguishes instruction and adjacent light detection-phase (over against stage position detection) over against the light of stage position detection (adjacent light detection-phase) is lighted the time interval between instruction.In addition, because imaging equipment body is independent in the light emitting control instruction that detects over against position probing and adjacent light for print cartridge to be detected, the sequencing that detects over against position probing and adjacent light of each print cartridge to be detected is not limit.

Another kind of optional mode is, if certain print cartridge need to be as the adjacent print cartridge of other print cartridges and is luminous, again as print cartridge to be detected over against position probing and luminous, and above-mentioned twice light emitting control is continuously, can only send that one group of light is lighted instruction and light extinguishes instruction, make this print cartridge luminous all the time, namely be equivalent to over against the light emitting control instruction folding of stage position detection and adjacent light detection-phase.This period duration is at least the first period T1 and the second period T2 sum.For this situation, above-mentioned the first period T1 refers to that lighting instruction from light begins to receive till the light quantity of position probing to optical receiver, till the second period T2 refers to receive light quantity that adjacent light detects and begin to extinguish instruction to light from optical receiver.Perhaps, above-mentioned the second period T2 refers to that lighting instruction from light begins to receive till the light quantity of position probing to optical receiver, till the first period T1 refers to receive light quantity that adjacent light detects and begin to extinguish instruction to light from optical receiver.In addition, if print cartridge to be detected over against position probing with as the luminous light emitting control instruction folding of adjacent light, the scheme of the present embodiment be applicable to that adjacent light detects position probing after or before the situation of execution.
