This site is working fine! Did buy a manual for SX-EX25L and after a while I could download it and fix the problem. Nice and easy!
 ;
Complete manual as pdf-file in very good quality. Very helpful and fast availability.
 ;
Complete service manual in very good scanning quality with all schematic and PWB graphics as well as assembly & maintenance instructions. A slight drawback is that the rastering of the PWB graphics sometimes makes it a bit difficult to follow fine traces, but no showstopper.

Purchased the manual that I was looking for at a great price and could download it easily.. Great service experience and for future purchases I plan to use the site. Thank you very much

Separation Corona
Optimum Adjusting Values: AC 57.0 ± 2.0 µA (D1) DC -8.0 ± 1.0 µA (leading edge: D1) DC -2.5 ± 1.0 µA (normal: D1 & D2) 1. Reinstall the TC/SC corona unit, and position the drum shoe at the center of the shaft so that the axis of the current sensing plate [A] is aligned with the separation corona wires [B] as shown.
AC current: D1 2. Select the ac 200 µA range on the digital multimeter. 3. Turn on the DIP switch on the switching PCB corresponding to �D1� on the TC/SC power pack PCB to turn on the separation corona. (The silk screen printed on the TC/SC power pack PCB is correct.) Adjust the corona current by turning VR �DAC� [C] on the TC/SC power pack. (Wait 30 seconds for the current to stabilize.)
4.
Leading edge dc: D1 5. Turn off the main switch, and select the dc 200 µA range on the digital multimeter. 6. Turn on the main switch, and adjust the corona current by turning VR �DC1� [D] on the TC/SC power pack. (Wait 30 seconds for the current to stabilize.) Normal dc 7. Turn on the DIP switches on the switching PCB corresponding to �D1 & D2� on the TC/SC power pack PCB to turn on the separation corona. (The silk screen printed on the TC/SC power pack PCB is correct.) 8. Adjust the corona current by turning VR �DC2� [E] on the TC/SC power pack. (Wait 30 seconds for the current to stabilize.) 9. Remove the drum shoe, and reassemble. 10. Check copy quality.
