The following is a summary of all the responses I received to my 'Where can I find laser toner and wiper pads' questions. Thanks to all of you that replied. Perhaps not surprisingly, NO ONE who replied has actually refurbished their own LaserWriter cartridges, although there were several who were willing to try if they could find a source of toner and pads. No one was able to provide me with a source for these items, so I am still in the dark about that. Most people are using commercial refinishing services which charge about $40 per cartridge. The quality of these services was considered by most to be questionable, with few people being really satisfied. Problems included various dots and smudges on the printed material, and in one case the colored toner content indicator became somehow detatched and rotated with the imaging drum. Another common problem was that gluey substances (such as Vaseline) used to hold in the toner during transport of the cartridge would melt in the high heat of operation and ooze onto the inner workings of the printer. Despite these problems, most refurbishing service users felt that the re-used cartridges provided darker output and lasted longer. Only one person named a particular company that they felt had given them good service; this was 'AMS Laser Supply' in Washington - no address or phone was given. Another person mentioned that his father-in-law ran a refurbishing business, but did not mention whether or not he had actually used the business's products. The address for this was: Geoff Sackson Foothill Microsystems 3131 Foothill Blvd., Suite M La Crescenta, CA 91214 (818) 249-6734 Several people set me straight on the refilling procedure. In addition to providing a few more details, most people also advised that 'I wouldn't do that if I were you.', for the following reasons: o As the moderator of comp.laser-printers mentioned, the toner in the LW is a carcinogen. Commercial refinishers do take careful precautions when doing the work. o The imaging drum is quite light sensitive and requires special care. My procedure didn't involve the imaging drum, but you do need to deal with it because of the excess toner reservoir. o There is an area of the toner cartridge that holds excess toner scraped of the imaging roller, and this area must be emptied if more toner is added. If this is not done, the reservoir will overflow and cause junk to accumulate in bad places. o The gears of the cartridge also accumulate junk during normal operation and should be cleaned. A few other details and facts: o Be sure to tape over the filler hole before replacing the cardboard on the cartridge. o Reset the colored toner indicator so that you have some indication of the age of the cartridge as you use it (it rotates with the imaging drum and does not sample the amount of toner inside the cartridge directly). o There is a toner drain plug inside the cartridge that you can use to put in toner instead of cutting a hole, if you are willing to do some disassembly. o Clean or replace the corona wire every time you refill.
