mechanism of all? photocopiers work. That is one and only one sheet fed in at a time for very nearly 100 per cent of the time. I know the rubber of the wheel has to have exactly the right degree of tackness/squashiness/clenliness. What other is necessary for reliability - pressure? speed? of roller, angle of attack? e-mail (removing .....) electronic hints and repair briefs , schematics/manuals list on http://homepages.tcp.co.uk/~diverse Nigel,Diverse Devices,Southampton,England |
