Inkjet printer question Answered

I need help, making an ink jet printer think that there is paper in the loader when there is not, there is a small switch with a leaver which tells the printer that paper is going through the roller but if it is taped down then the rollers go for a while and then the printer realities that there is no paper, is there an easy way to fix this? Also on my ink cartridges there are 7 pins, does any one know what these do? I'm trying to build a laser cutter out of this printer where the laser is controlled by when the black ink would be spraying. Thanks in advance.

Well i don't know that what are you trying to experiment with printers but still i think that i can help something about inkjet cartridges. But i can't say that it will help you or not. but surely it will increase your knowledge about inkjet cartridges that you want to do things with.

I hope that this will help you.....

Thank you, I have found the switch that tells it where the paper is, but it does not work if that switch is pressed all of the time, it expects for when nothing is happening then the switch is released, and it also uses that switch to detect when the paper is all of the way through. It requires a sequence of presses and releases to work, is there a way to make it not even use that switch and not detect weather or not paper is there, and just print?

Your printer is designed to feed a sheet of paper and print on it (I hope it's not a Canon - I hate those things). If you're seriously hacking it, you need to replace the control mechanisms - there isn't an easy way to "fix this" you have to rebuild it. L

Generally devices like this have several paper-detection devices in order to know where the paper is. The machine will need to feed a sheet to the correct position to start printing, then it will need to eject the sheet. Sometimes these are microswitches, other times they are LED-photodiode switches. If you're going to take this apart to rebuild as a laser-cutter have a look for as many of these as you can find. Think about which of these switches the printer expects to be on or off as part of the normal printing process. L
