From the material safety data sheet packed with each DEC LN03 toner kit: Ingredients percentage Ferrosoferric oxide 55 Styrene acrylic resin 45 "The primary toxicity of this material would be expected to be associated with the nuisance dust characteristics of the chemical mixture. Neither of the two chemical components of the product are listed by any of the primary regulatory or research agencies. Precursors (i.e. styrene and acrylic acid) of the syrene acrylic resin are recognized to be toxic, there are no data in the open scientific literature which indicate a toxicity associated with this resin itself. " First Aid: "Inhalation: If a person breathes in large amounts of material, move the exposed person to fresh air at once. If breathing has stopped, perform artificial respiration. Keep the affected person warm and at rest. Get medical attention as soon as possible." I would guess that, except for particle size, NEC toner is remarkably similar to DEC toner. In other words, don't inhale it. We don't hink it will hurt you if you do, but if we say that we open ourselves up to massive litigation from people who eat strange things for fun. (To paraphrase DEC.)

John – Thanks for the very interesting notes on DEC toner, particularly the "first aid" section! I have been told (by NEC) that the NEC toner particle size is so small that it will fly right through a vacuum cleaner bag. They use a special vacuum cleaner to clean NEC-800 series printers that are in for service. The key in taking apart an NEC-890 OPC cartridge is to remove the drum VERY CAREFULLY and avoid both spills and dust. Interestingly, I've found that all parts (except the drum) can be immersed in water, cleaned completely, and left to dry thoroughly. Upon re-assembly, the OPC cartridge will work fine. Kerry
