The Silver cartridge is one of three cartridges currently available for printing and is the key reagent in forming conductive silver (hence the name Argentum..). Reaction with the Ascorbic or Ascorbic+ cartridge causes silver particle formation. Silver will decompose and react under UV light causing staining. It is important to always ensure that the Silver cartridge is in the cartridge slot closest to the front of the Argentum to ensure that the Ascorbic layer is printed before the Silver layer.
The Silver cartridge contains a solution with silver nitrate as the active ingredient. Silver nitrate in solution is corrosive and should be handled with care. Always exercise the follow precautions when handling Silver cartridges.
- Wear gloves and eye protection when priming the cartridge.
- Dispose of all materials after contact with Silver ink.
- Wash hands thoroughly after handling the cartridges.
- Keep cartridge out of reach of children.
- If you suspect the cartridge is leaking, dispose of it immediately.
Silver nitrate will stain skin after contact. If you notice dark marks on your hands or any other part of your body after handling the cartridges, reevaluate your safe handling procedures. If swallowed or contact is made with face or eyes, rinse and seek medical attention immediately.
Clean cartridges print better. Always recap your cartridges when they will not be used for extended periods. If they have been left uncapped and require cleaning, see the cleaning section below.
If a cartridge has been left uncapped for an extended period, silver nitrate will crystallise on print head. It is possible that these may not be visible immediately depending on the duration of exposure.
- Using gloves, wet a piece of paper towel or a disposable cloth/rag with distilled water. Do not use a tissue or other material which will easily disintegrate on the nozzles.
- Over a bin, wipe the nozzles back and forth using a small amount of force until the nozzles appear clean. Use additional paper towel or water as necessary.
- If still not clean, substitute water for isopropyl alcohol. DO NOT use rubbing alcohol, methylated spirits, mineral turpentine (white spirit) or other solvents.
- Dispose of paper towel/cloths safely and wash hands.
