Wherein address wire:It is C, M, Y that ADDR3, ADDR4, ADDR6, which distinguish corresponding color, and remaining address line does not participate in spray directly
Head printing.Same second model printer passes through control line:Electric signal on Pt_Ctrl1, Pt_Ctrl2 drags down to control ink
Box B shower nozzle ink-jet.Control line Pt_Ctrl1 and Pt_Ctrl2 to drag down the duration totally consistent, but time of origin is present
Difference.Pt_Ctrl2 starts its electric signal in the 0.4us that Pt_Ctrl1 electric signal is dragged down after release and drags down action.
The difference of the first model printer and the second model printer head control signal it can be seen from above-mentioned analysis
Essentially consist in control line Pt_Ctrl1 and Pt_Ctrl2 sequential:The Pt_Ctrl1 and Pt_Ctrl2 of first model printer are simultaneously
Start electric signal and drag down action, while tenth skill;Duration 0.6us is dragged down for the first time, the duration is dragged down for the second time
0.75us, is spaced 0.8us(Specific sequential is shown in Fig. 7).The Pt_Ctrl1 and Pt_Ctrl2 of second model printer successively start electricity
Signal drags down action, and Pt_Ctrl1 electric signal drags down 0.4us after release, Pt_Ctrl2 just start its electric signal drag down it is dynamic
Make;Also, duration 0.2us is dragged down for the first time, duration 0.84us is dragged down for the second time, 0.4us is spaced(Specific sequential is shown in
Fig. 8).
Furthermore, it is possible to which the difference existed also has:For selecting the address wire of shower nozzle point different, the ground for selecting shower nozzle point
Order on the line of location is not equal.
The spout signal converting unit of regeneration chip receives the second model printer head control letter from the second contact
