Christian, you can repair this on your own with a soldering iron, heat shrink tubing, a heatgun, and the most important tool, a simple volt meter. A cheap volt meter will do, since you will be checking one end of a wire (or plug) to the other using the ohm meter function, checking for continuity. Since the wires are mostly color coded, by using deduction, careful observation, and common sense you should be able to bring it all back together. Touch one probe to one wire end, keep touching the wires with the other probe , watching the meter swing, registering continuity, until you find the match. Get some similar guage wire, strip them down, put a length of heat shrink tubing on, and solder the wires together. Recheck the continuity with the ohm meter, then use the heat gun or a hair dryer on hot and shrink the wrap on the wire and start on the next one.
This would be a horriffic job, however. If you have no recourse, you might be forced to do this.
Your best approach if no service person is available, would be to buy replacement cables and start replacing them one by one. You could begin by using the repair manual.
There's one for download on
http://z3200.comYou might be better off replacing the printer, however. A hint regarding avoiding future disasters with those pesky critters:
Mix cayanne pepper and water and stir thoroughly and use a spray bottle, like for windex, and spray down all the wire surfaces. They don't like the pepper and should leave it alone.
If you're in an absolute pinch and must fix the printer yourself, know it can be done. Lots of concentration, research pouring through the manual, looking for and finding a parts list for the cables, and sheer unswerving concentration, taking it one step at a time and you can fix this.
Good luck!
