A940 printer stalls and gives a hardware message
This is a usual problem whit this model of printer, i had been thru this three times already.
In my case, the printer stops completely halfway printing and shows "Hardware error 502", i found that is because the optical sensor strip is dirty, first you should try to clean it with out removing it form the printer, to do this you should:
(The optical sensor strip its an nearly transparent plastic strip behind the print head, if you look closely it has very thin lines painted on it, this is used by the printer to measure the movement of the print head)
1- Print something to case the hardware error and shut it down immediately
2- Disconect the printer
3- Lift the scaner part of if, as you do when adding ink.
4- Look where the print head (the ink cartiges) is, this is where the stain is
5- Get the print head out of the way (just slide it left or right)
5- Use a soft cloth with little water to try to clean it, if it doesn't work try isoplopile alcohol because sometimes the stain is ink and is very hard to remove
6- Try print again and repeat as necesary
if you can't clean it this way you must remove the strip and clean it.
(You must have plenty of time and patience to try this, or you can dissasembly the printer entirely if you want to re lubricate or something)
1- Move the printer head all the way left, and with some pointy object pull the metallic wire holding the the strip at the right edge (flashlight very usefull), it's marked with and "D", remember that.
2- Move the printer head to the right and remove the plastic strip (this side is very easy), it's marked with an inverted "F" (it's on the other side) and an arrow indicating the up direction
3- Inspect how dirty is the strip and clean it the way you want (not so aggresively, the strip hasn't the fault)
4- Put again the left side of the strip and make it pass behind the print head
5- Move the print head to the left
6- Put the right side of the strip whatever you can, this is a very tedious process because the reduced space available, remember to keep the left side in place, because it's impossible to put the right side first.
7- Re connect and power on your printer, if it immediately gives hardware error 502, the strip is misplaced, move it a little up, down, backward an forward trying to get in place and try again, or consult the respective solution en this website.
8- If you can turn on the printer it should print now, try it, if it works, Congrats!
Sorry for my bad english
