Hello all!
I managed to get that old 1310 going.. the thermistor was stuffed - I used a 1550 thermistor element and shoved it inside the original holder. It works!
Anyway, now I'm greeted with BLACK copies. The test chart image is visible amongst the toner mess, but only just. The optics are clean. If I remove the main charge I get blank copies, as expected. The exposure lamp can be varied in brightness. I can't remember where and how to measure the bias voltages on these, but varying the main charge voltage varied the depth of the black copies.
Any hints? Stuff I should try? This old banger should be on the dump but I should be able to make a dollar or two out of it if I get it working.
Wagon.
