i am a total noob here ,
advice needed on how to make this ?
what i have :
the printer HP1360 (not gutted yet)
the main thing i want is that the gantry which holds the printer has to MOVE and the paper STAYS in position, as per the video ,
(unlike regular printer where the printer stays and the paper moves)
in the description he mentions:
This is the insides of an HP1360, the paper feed encoder is being used to drive a stepper motor to move the gantry. The encoder is decoded and divided by a parallax propeller microcontroller that also detects the paper feed and ignores other paper feed motor rotations. The gantry is moved by a cable drive to be replaced by a belt.
sent him an email about the detailed mechanics , but he haven't responded yet
so guys , aside than the printer itself what other things should i buy ?
and how would i "decode the encoder and divide it"?
The basic mechanics of getting the print head to move sideways on a gantry that moves up and down the page should be fairly simple if you have a couple of stepper motors - presumably they are in the printer although one of then is organized to move the paper. It may be that that motor isn't strong enough to move a gantry which would be much heavier than a sheet of paper.
The big problem, I suspect, will be getting the print head to spit out the correct ink at the correct time - unless you use the printer electronics. Maybe you could rearrange the printer mechanicals without changing the electronics and it "wouldn't know". However that would not be an Arduino project.
I can't imagine how one would program an Arduino to take in data from a PC and make a picture on paper. I don't even have a clue what format the data is in when it is sent from a PC to a printer.
Back in the day (before PC colour printing) you could get colour plotters that worked like the thing in the video but used pens to draw pictures. HP used to make them. It was cool to watch the pens pick up and put down as the different colours were needed. I could imagine controlling something like that with an Arduino but it would not be simple.

...R
thanks for the input ,
but based on the video , he didn't change the electronics , just did what you said rearangging the mechanicals so the printer wouldnt know ,
as per what the description of the video said ,
"This is the insides of an HP1360, the paper feed encoder is being used to drive a stepper motor to move the gantry. The encoder is decoded and divided by a parallax propeller microcontroller that also detects the paper feed and ignores other paper feed motor rotations.

the thing is i am a total noob here , i dont know what he means by decoding the encoder and dividing it with a
"parallax propeller microcontroller" , is there a coding required ? if so how to learn the codes ?
for the experts in this forum , sorry if this is a dumb question. but i am willing to learn
