haracteristics of the pulses, and many other limitations regarding the triggering pulses,
are mentioned in Gilliland’s book .
The optimum firing energy of the print cartridge is about 40 microjoules. This
means that the pulse width can be equated to the voltage using the following equation:
2

65 0.00004
voltage
pulsewidth
voltage
pulsewidth resista ce energy





Gilliland has calculated this for the optimum values for this, and provides this
table (the pulse widths have been rounded to the nearest half microsecond) :
Table 1: The firing times at different voltages
Since these are described as the optimum pulse widths, it may be possible to
change the pulse widths so they do not exactly match up with data in the table; Gilliland
states that changing the pulse times may be an option, but that performance may drop .
He goes on to elaborate, saying that reducing the pulse time could result in poor droplet
quality and clogged nozzles, while too long a time (and energy) could burn out the
resistors .
Gilliland also notes that with the extremely short pulse times, it might be better to
use a lower voltage with a longer pulse time, increasing the amount of control the

programmer has on the pulse width. The reason for this is that at such short timespans,
the microcontrollers processing time becomes a significant factor; for example, the
arduino board takes approximately 3 to 4 μs to turn an output pin on and off with no
commands between the on and off commands. This means that, since the microcontroller
being used is the arduino, the voltage cannot be over about 26 volts (and may run into
some difficulties at 24 volts) .
Gilliland recommends that the time between the same nozzle being fired twice
should be at least 800 μs . This criterion is based on the time taken for the ink to refill
in the chamber, and any firing at a faster frequency will result in poor quality printing.
The HP 51604A specification sheet states that up to two nozzles, and no more,
can be fired simultaneously. Gilliland suggests that this is because of the limit on the
energy that the conductors within the print cartridge can effectively deliver. Gilliland
also says that two adjacent nozzles cannot be fired simultaneously, as this will give
unpredictable results. This is probably because the droplets would interact, and could end
up some distance from the intended target based on the relative velocities of the droplets.
Gilliland goes on to suggest that maximising distance between nozzles being fired at the
same time will give the best and most reliable performance .
The dead time, or the time between firing two pairs of nozzles, according to
Gilliland, is 0.5 μs . Although Gilliland does not explicitly state a reason, it is likely to
be because this is the minimum gap required to prevent the aforementioned issues of
energy limits on the circuitry and interference between droplets.
A lot of these specifications will not cause the printer to fail, but will adversely
affect the print quality. Gilliland makes a significant effort to emphasise that print quality
is entirely subjective, and that the designer must decide whether the quality of the
printing is good enough for the given application .

那么希望你能倒过来，用两台打印机改成一台贴片机。其实这种光栅的准确度也足够贴0402了，造福大家吧

做好烧毁墨盒的准备先. 能量少了不出水,能量多了烧喷嘴. 我上次成功用N个这种墨盒做出了一台手持莫尔斯码打印机.

一台喷墨才2百多，值得这样干吗？

恶心的hp墨盒喷头一体设计，墨水没了就连喷头一起扔。记得欧盟把hp和epson都给告了，说它们严重污染环境。

epson好点，分离设计，可以用连供。

你好，最近我也在用HP 51604A墨盒做开发，现在不是很了解12个点的时序控制，不知老师可否提供相关开发资料给我，学生不甚感激。QQ邮箱：279974526@qq.com
