The specific embodiment

As shown in Figure 2, direction X is the installation direction that print cartridge 200 packs printer into.Print cartridge 200 has housing 210, and housing 210 has roof 201, diapire 202, antetheca 203.The outside of antetheca 203 bottoms is provided with ink outlet port 221, and the outside on top is provided with the first occlusion part 222, and the outside at middle part is provided with the second occlusion part 223.Whether the first occlusion part 222 is in place for detection of print cartridge 200.After print cartridge 200 is in place, the first occlusion part 222 blocks first of printer and detects light, prevent that this first detection light from arriving the first sensor of printer, the second occlusion part 223 blocks second of printer and detects light, prevents that this second detection light from arriving the second sensor of printer.On occlusion part 223, by bonding or other assembling mode, be fixed with substrate 224, on substrate 224, be provided with light-emitting device 225.Light-emitting device 225 is electrically connected to chip 230 by substrate 224 and wire 226.It is luminous to the second sensor of printer that chip 230 is controlled light-emitting device 225, that is, the time bright or that go out of light-emitting device 225 is controlled by chip 230.

As shown in Figure 3, chip 230 is arranged on the outer surface of housing 210 and is positioned on roof 201, and electric contact 231 is positioned at chip 230 back to a side of print cartridge 200.

As shown in Figure 4, chip 230 has controller, memory, driver and communication section.Electric contact 231 is as the communication section that is used for carrying out communication with the communication interface of printer mainboard.The memory stores of chip 230 have ink balance information and with the type control information one to one of print cartridge.The type of the print cartridge 200 of the present embodiment only comprises capacity feature.

Control information is subdivided into the control information T0 that starts the period, the control information T1 of the first period, the control information T3 of the 3rd period of control information T2 of the second period, the control information T4 of the 4th period successively.It is not luminous in chip 230 and the communication interface of printer mainboard are successfully set up after being connected 3 seconds of communication that control information T0 controls light-emitting device 225.Control information T1 controls luminous first scheduled time of light-emitting device 225, and control information T2 controls light-emitting device and extinguished for second scheduled time, and control information T3 controls luminous the 3rd scheduled time of light-emitting device 225, and control information T4 is variable control information.When the ink surplus of print cartridge 200 is sufficient, control information T4 extinguishes the control information of the 4th scheduled time for controlling light-emitting device 255.When print cartridge 200 ink surpluses are not enough, control information T4 is for controlling the control information of luminous the 4th scheduled time of light-emitting device 255.The ratio of second scheduled time and the 3rd scheduled time is corresponding one by one with the type of print cartridge 200.

New print cartridge 200 ink surpluses are sufficient, and while dispatching from the factory, the control information T4 on its chip 230 is set to control the control information that light-emitting device 255 extinguished for the 4th scheduled time.New print cartridge 200 packs into after printer, and the first occlusion part 222 blocks first of printer and detects light, and printer assert that print cartridge 200 has successfully packed into.But the second occlusion part 223 blocks all the time second of printer and detects light after print cartridge packs printer into, the communication interface of printer mainboard and the communication section of chip 230 are set up after communication is connected, chip 230 according to the control information in self memory control light-emitting device 255 " go out-bright-go out-bright-go out " luminous one time.Wherein, startup period chip 230 control light-emitting devices 255 are set up communication at the communication interface of printer mainboard with the communication section of chip 230 and are connected in latter 3 seconds not luminous, printer can not be identified the type of print cartridge 200 and restart immediately print cartridge installation and measuring program in the communication interface of printer mainboard and the communication section of chip 230 are set up after being connected 2 seconds of communication, waits for print cartridge is installed again.The communication interface of printer mainboard is set up communication with the communication section of chip 230 and is connected after 3 seconds, and printer the second sensor detects the optical signal that light-emitting device 255 sent in the first four periods of period to the.In " high-low-high-low " level that its second sensor of printer comparison detected in the first four periods of period to the, whether the second accounting predetermined with printer with the accounting of " low-height " level of the 3rd section be consistent, if the type of assert print cartridge 200 inconsistent is not that print cartridge is changed in the predetermined toner cartridge type of printer prompting, if unanimously allow to continue to detect ink surplus.Printer assert that according to the height of final stage level in above-mentioned " high-low-high-low " level whether ink surplus is not enough, if high level is assert that print cartridge 200 ink surpluses are not enough and is pointed out and change print cartridge, if low level is assert print cartridge, 200 ink surpluses are sufficient, allow to continue executable operations.Obviously, new print cartridge 200 ink surpluses are sufficient, in the situation that the type of print cartridge 200 is consistent with printer predefined type, printer allows to continue executable operations.Before printing, printer reads the ink balance information in chip 230 memories, after printing, the lower threshold comparison that printer disappears deduction to set in new ink balance information after ink consumption and printer, if directly new ink balance information is write to the memory of chip 230 and finishes printing higher than this lower threshold, if the control information T4 of chip is revised as and controls the luminous control information of light-emitting device 255 lower than the lower threshold of setting in printer, more then the memory that new ink balance information writes chip 230 is finished to printing.

When being printed to machine maintenance, the control information T4 of the not enough print cartridge 200 of ink surplus changes the control information of controlling luminous the 4th scheduled time of light-emitting device 225 into, it packs into after printer, chip 230 control light-emitting devices 255 " go out-bright-go out-bright-bright " a luminous light, printer the second sensor detects " height-low-height-height " level within the first four periods of period to the.In the situation that the type of print cartridge 200 is consistent with printer predefined type, printer is that high level assert that print cartridge 200 ink surpluses are not enough according to the final stage level in above-mentioned " height-low-height-height ", and non-print operates and points out and change print cartridge.

Obviously, the type of print cartridge is not limited to only comprise capacity information, can also comprise at least one feature in color, ink solvent type or ink viscosity.

The chip of print cartridge is not limited to be arranged on the roof of print cartridge, can also be arranged on other wall of print cartridge, only needs to guarantee that can form communication with the communication interface of printer mainboard is connected.

When communication section is electric contact, the communication interface of printer mainboard is also electric contact.But communication section of the present utility model is not limited to electric contact, can also be radio-frequency coil, now the communication interface of printer mainboard is also radio-frequency coil.

The light that each occlusion part of the present utility model sends the light emission part of printer " blocking " is not limited to optical signal to block, and can also be that the light that the light emission part of printer is sent by the mode reflecting or reflect departs from original path and can not arrive corresponding light receiver.

The light that light-emitting device sends is not limited to visible ray, can also be black light, as long as the type of the light that the type of the light that light-emitting device sends receives with the second sensor arranging in printer is consistent.
