Abstract

A major problem in start/stop slide mechanisms previously used in magnetic ink jet printers is the build-up on the face of the nozzle. This causes the ink jet stream to deviate from its original target point after repeated start-up and shut-down operations. The build-up consists of a mixture of ink and sealing fluid used in the system.

Monawet Flush Fluid

A major problem in start/stop slide mechanisms previously used in magnetic ink jet printers is the build-up on the face of the nozzle. This causes the ink jet stream to deviate from its original target point after repeated start-up and shut- down operations. The build-up consists of a mixture of ink and sealing fluid used in the system.

Alternate start-up/shut-down schemes are based on a clean nozzle face after each start/stop operation. A key fact¤r in such a scheme is a flush fluid which would create a clean nozzle face after each operation. The flush fluid must possess the following properties:
1. Remove ink contaminate;
2. Not leave residue;
3. Be compatible with the ink, that is, it must not

destabilize the ink.

A flush fluid which meets the above requirements consists of 1.0% solution of MONAWET MM-80* (sodium dihexylsulfosuccinate) in deionized water. This anionic surfactant is commercially available and has found widespread use effective for cleaning glass. It can also function as a stabilizer and emulsifying agent, and has been used in inks and paints for just that purpose.

A 1% solution of MONAWET in deionized water is effective in removing magnetic ink residues without leaving a residue. In addition, this flush fluid is compatible with magnetic inks, and does not cause the ink to destabilize. *Trademark of MONA Industries Inc.
