The printer back to normal

I took about 2-3 hours to figure out what exactly the problem to my false paper jam error. Then I borrow tools from my friend to dismantle all the component into pieces. With a little knowledge about printer, so I took a risk because I already fed up with the false paper jam error.

Before I unscrew the printer cover, I look at any possibilities a hidden screw so that I don't make damage on the printer. After that I open the cover then the component inside. I just follow my instinct when open it. I try my best to dismantle the component and remember every screw for each holes.

After dismantle into pieces, I found something that really attract my attention. Something like a switch or a sensor (something like that) that detect a paper was lift down. Which I suspect the main problem to false paper jam.

Before I put the component back together, a look through all the component to see if there another (alien) that make my printer detect a paper jam again. Then I screw back all the component and put the printer back.

Then I try put the power supply cable and the USB cable. Thank god everything back to normal. Haha... I finish doing the investigation at 4.05 am. The printer can be use again as usual. If the problem still exist just now, I'm thinking of buying a new printer. That is why I'm dare to dismantle the printer just now. But so far so good so I don't have to buy a new printer.
