Cleanup of the Model 105 is fast and easy. Ink should never be left and allowed to dry on the machine or print dies. The solvents you use should be selected for compatibility with the rubber parts of the machine as well as for dissolving the ink. Solvents commonly used for clean up include isopropyl alcohol (anhydrous), acetone, lacquer thinner, denatured alcohol, and others that do not leave a residue. Do NOT use the ink thinners or reducers for cleanup. Start by removing the print unit from the print arm of the machine. The print die should be cleaned with a solvent that is compatible with the die. Rubber or polymer die materials can be damaged by some solvents. Care should also be taken so that the die is not damaged by abrasion, particularly if a soft material is used for a die. Next, clean the ink roll. The best way is by wiping with a clean soft rag, moistened with solvent. Never submerge the ink roll or any other rubber part in solvent. Wipe the ink roll clean and allow the solvent to immediately flash dry. When the ink roll is clean, park it with the ink roll latch. The Ink plate is now accessible for cleaning. Use a clean soft rag, moistened with solvent to wipe it clean. It is also good practice, particularly if changing colors, to clean the ink roll and ink plate prior to beginning a print job. This will assure there is no residue, dust or other contamination on these surfaces that will affect the job.
