There are reasons other than economic ones why a company might try to discourage you from refilling your own toner cartridges. Also, to the best of my knowledge, the problem with using photocopier toner can also be due to differing polarities of the toner particles. --Rick ]] I have a couple of questions about refilling LaserWriter toner cartridges. Briefly, they are: 1) Is my conception of how to do the refill correct? 2) Where can I get laser toner? 3) What is the correct amount of laser toner to place in the cartridge? I have seen several people use the following technique to refill their cartridges. Naturally, you try this AT YOUR OWN RISK. Both Apple and Canon warn of horrible tortures that will befall those who do this, and whether this is because they want your $100 per cartridge or because you are likely to damage your printer is debatable (although most people seem to think the former!). I do know that the imaging cylinder is contained in the LW cartridge, and probably doesn't last forever, so the number of refills you can do on a single cartridge is probably limited. It is NOT possible to use photocopier toner in the LW; laser printers require a much finer powder than a garden-variety xerox machine. Anyway, to refill a cartridge you apparently do the following: o Remove the old cartridge from the LW and locate the place where a long, rectangular piece of thin cardboard with storage instructions, etc. has been pasted on the cartridge. If you hold the cartridge as if you were going to insert it back into the printer, this cardboard will be on the very top of the cartridge, on the right hand side. o Work a knife blade underneath the cardboard and remove it. It is glued on, but should come off in one piece without leaving any extra shreds of paper behind. Save the cardboard. Underneath the cardboard you should find only an area of unblemished plastic. o With a hot soldering iron, cut out a hole in the center of this plastic about the size of a quarter. BE VERY CAREFUL TO PREVENT ANY SMALL PIECES OF PLASTIC FROM FALLING INTO THE HOLE! If bits of plastic get into the toner reservoir they can seriously damage the printer. This is why you must melt the hole out rather than use a knife or other tool that is likely to shatter the plastic. o Allow the plastic to cool, then funnel in the appropriate amount of toner. o Glue the cardboard back flush against the plastic with a dab of Elmer's glue or equivalent. Be sure to keep the glue away from the area of the hole! o Shake normally and re-install. o Wipe off the cleaning bar from the binding assembly as best you can with the edge of a piece of paper, then put it back. I read in this month's Computer Shopper that a company called 'Lazer Products' sells toner appropriate for use in refilling LaserWriter toner cartridges, and also the wiper rods that are used to clean each page as it comes off the binding rollers. Does anyone out there have any information about this company, or know where the right kind of toner can be purchased? A number of other companies will take your old cartridges and 'refurbish' them for about $40 - I believe that they do more than just put more toner in, however. Does anyone know anything about this refurbishing process? I'd be very grateful to hear all comments, concerns, and personal experiences you have had with this kind of thing. I will summarize all replies that get sent to me after a week or so in comp.laser-printers and comp.sys.mac. -------------------- Garth Snyder UUCP: seismo!hao!boulder!garth Univ. of CO @ Boulder ARPA: garth@boulder.colorado.edu -------------------- -- -------------------- Garth Snyder UUCP: seismo!hao!swatsun!garth Univ. of CO @ Boulder ARPA: garth@boulder.colorado.edu --------------------
