Abstract
Binary-programmed vector is generated on ink gun from sequence signal of printer body. Based on selectivity of the programmed vector, binary original identification code on the ink gun is read out in sequence, mixed as well as reordered. Finally, reordered identification code is converted to printer body cognizable binary signal, which is output to printer body. The said binary signal is compared with signal stored in printer body to complete identification.
Description
Technical field
The present invention is about a kind of method of identification ink-jet printing head, refers to a kind of discrimination method of confirming this ink-jet printing head and connection printer main body compatibility that is applicable to especially.
Background technology
The brand and the type of ink-jet printer are quite various on the market at present, and whether the ink-jet printing head of purchasing in order to confirm is applicable to this printer main body, often must finish by an identification mechanism.Fig. 1 shows the outward appearance and the configuration of general printer main body 90 and ink cartridges 99, wherein set firmly an ink-jet printing head on the ink cartridges 99, one drive integrated circult chip then is attached on this ink-jet printing head, and this chip has pattern and the state of an identification mechanism for printer main body 90 identification ink cartridges 99.
Fig. 2 shows a kind of known identification mechanism.Among the figure, original identification code storage circuit 91 stores one group of (this figure comprises six) identification code, 92 of bit shift registers receive two-phase (two phase) clock signal CLK1, CLK2 and reset signal RESET from printer main body 90 respectively by address signal contact 931～933.Reset signal RESET can be sent to bit shift register 92 by the output contact 911～916 of correspondence abreast with identification code, and activates clock signal CLK1 and CLK2 by printer main body 90, and the identification code that bit shift register 92 is received pushes to interface circuit 94 in regular turn.Can convert identification code to curtage in regular turn through interface circuit 94, but and amplify and make printer main body 90 identifications.At last, this curtage is sent to printer main body 90 via the output contact 95 of ink-jet printing head 99, and compares, finish the affirmation program with the identification code of printer main body 90 inside.
Yet aforesaid identification mechanism obviously can only provide a kind of identification code according to original identification code, and the printer main body that is suitable for this pattern ink-jet printing head also must be provided with identical identification code, even printer main body is different types or makes batch.This design is for the obvious underaction of the matched combined of printer main body and ink-jet printing head and clear and definite.The inventor in view of this, according to the professional knowledge and the experience of association area for many years, at the problems referred to above actively research and development study, find the method for identification ink-jet printing head of the present invention finally, with this Jiahui industry.
Summary of the invention
Fundamental purpose of the present invention is to provide a kind of method of identification ink-jet printing head, and the identification code combination that can derive different is to confirm the applicability of different printer main bodies.
For reaching above-mentioned purpose, the method for identification ink-jet printing head of the present invention comprises: the default one group of binary original identification code of step a) is in this ink-jet printing head; Step b) connects this ink-jet printing head and this printer main body; Step c) is sent to this ink-jet printing head with clock signal by this printer main body, and produces binary program vector (sequence of vector); This ink-jet printing head of step d) optionally reaches in order according to this routine vector and reads, sized-multiple reaches this binary original identification code of sequencing again; The step e) identification code of sequencing again converts the cognizable binary signal of this printer main body in regular turn to; The binary signal that will reach after step f) will be changed exports this printer main body in regular turn to, compares to finish identification with the signal that is stored in this printer main body.
