Ink Jet Printer Cleaning Solution

Foreign matter in an ink jet printer clogs the small openings which are incorporated in this type of printer. This cleaner effectively removes these particles and prevents a large part of the clogs.

Foreign matter - solids - can and do cause many problems. These problems arise from the fact that a very small particle can stop the flow of ink, thus stopping the operation of the machine. This results in expensive downtime, delayed schedules, loss of print time and servicing to clear the clog and return the machine to active duty. These foreign particles can be house dust, pollen, milling debris or any small solid particle.

Typically, the ink path of the machine is flushed with water and surfactant to dislodge and remove this type of matter. This method has not proven satisfactory, even though many of the parts are cleaned untrasonically.

The cleaning solution described here is an improvement on the water flush method. This cleaning solution utilizes a water soluble resin to increase the viscosity of water and a surfactant to reduce the surface tension of the water. The surfactant is used to lower the surface tension so that the water will effectively wet the particles. The water soluble resin is used to increase the viscosity so that the particle, once wetted, will remain suspended longer. The suspended particle will move with the cleaning solution, so that when the cleaning solution is discharged from the system the foreign matter...
