Manual for BASF6105 8inch Flp drive

Some solvents will soften and distort the plastic immediately. This is bad enough, but at least you can test them on an unimprtante area. Woest, though, some slovents can attack the plastic laving it waek and/or brittle. You don't notice this at the time, only after you've ruind the part by completley cleaning it and it falls apart. One of the worst jobs is cleaning up an HP9810/20 printer mechanism where the platten roller has decayed. Unlike the card reader roller i nthe smae machine, which turns to a crumbly powder, the platten turns to a black goo which gets _everywhere_. It's partciularly bad if there's no paper i nthe pritner at the time, bcasue the thermal printhead gets coated i nthe stuff. That part has to be clean to work properly, and it's delecate, s oyou don;'t want to rub it too hard. At least it's a ceramic subrstate on a meatl abcking plate, so no common solvents will attack it. I believe that's what we call 'WHite spirit' over here. It is quite useful (and cheap) for things like this. I find that naphtha (lighter fluid) and propal-2-ol are the only solvents I routinely use. They're safe on most computer parts nad one or other will normally shift most forms of gunge. -tony
