Step 4: Verify

Now that your paperclip is securly in place shorting the red and black wires out of the coinbox, check the copy machine's screen. It should now have different paper sizes and let you change the # of copies you are allowed to make.

most of the time the colors are not coded properly, there is 5V and ground to Enable the copier, BUT there is also 16 to 36 VOLTS for the pulse signal. If you connect the wrong wire you will FRY the machine's main board. I know because I work on these. You are a smart Thief, nevertheless, a thief you are. Perhaps you should get a job to afford the 10 cents and find out how the real world works.

Why bother with the paper clip ??? if you got a xerox machine I will can tell you how to switch off the coin/swipe machine :) have fun guys
and can you just tell how...
haso sharky2374 years ago
yeah, but then you'd have to use a xerox... *shudder*

seriously though be careful, can hurt yourself and the boards in those old machines aren't easy to source anymore! not in AUS anyway
