Serial Inkjet Printer - Need Help... Something's wrong

manny175

Here's what's happening:

I already have a boebot... I bought a serial inkjet development kit....· connected the serial inkjet printer circuit board with 3pin wires to the boebot pin#15 (white·on the outside) (on serial inkjet circuit: black wire connected to G)...·connected the print cartridge and carriage assembly to inkjet circuit board (i tried it bought·sides of the ribbon... loaded to my boebot the·Simple_Print.bs2 which i downloaded from·parallax website (at this time boebot is on)... then turned on the inkjet circuit board which shows a redlight... what do i expect next?... cause the printer as·i wave the cartridge over paper wont print... i have a multimeter by the way... and the battery's have·at least 1.5v x 4 = 6v... jumper in my boebot is at Vin... I have called parallax regarding this and they let me send the items for exchage which i appreciate.... however to my frustration, when i got the new one and tried the procedure again, nothing happened... where·did i go wrong? certainly not the materials (circuit boards, printer cartridge and carriage)? what do you think? I'm new to the inkjet printer kit... but my boebot works.·

You need to set the jumper to Vdd and not Vin, the Ink Jet printer module is a 5v device.· Have you tested your I/O pins to verify that they are working properly?· You could try another I/O pin and change the code to match.

Thanks Dave for the response... but unfortunately its not working... I did set it to Vdd... and it still did not work... i tried using the I/O pin #14 in my boebot because i know I/O pin #14 should work since i used it already... i copied the Simple_Print.bs2 and named it Simple_Print_pin14.bs2 and changed the lines 'Inkjet CON 15' to 'Inkjet CON 14' and 'SEROUT Inkjet, Baud, [noparse][[/noparse]Esc, "C", 15]' to 'SEROUT Inkjet, Baud, [noparse][[/noparse]Esc, "C", 14]'. Any more ideas? By the way, when i run the Simple_Print program (loading it to boebot) and turning on the Serial Inkjet Circuit board, do i expect the printer cartridge to print automatically?... or is there an hp promt or a dialogue box that i should see in my computer screen?

I am in Glendale, California (near los angeles, california): do you know anybody I could go to personally for help? I am really interested in this technology... if only i could just make Simple_Print.bs2 work.
