Printer / Print Heads Maintenance Procedure (once Daily)

Health and Safety

• • Always wear safety glasses and rubber gloves when handling ink.

• • If ink or cleaner makes contact with a person’s skin, hair, eyes, or clothes, refer to Treatment for Hazardous Substances on the image

• • Check regularly for kinks or other stoppages in the lines.

• • Never clean the print heads with pressurized air.

• Do not allow the ink or cleaner level to fall below the bottom of the pick-up tube. The air will negatively effect print quality and cause damage to the print head.

• • Always store extra bottles of ink and cleaner in a temperature-controlled area. The temperature must stay above 32 degrees Fahrenheit to prevent ice crystals from forming and clogging the printer.

• • Never pressurize a bottle while it is positioned outside the bottle holder.

• • Never exceed the recommended pressure setting of 12 psi.

Cleaning the Print Heads

• 1. Lockout/tagout the pneumatic system’s main regulator. • Note that the top clamp (infeed side) will lower when air pressure is removed.

• 2. To ease access to the print heads, follow the instructions in Raising the Top Clamp to secure the top clamp in place:

• 3. Pour some of the cleaning solution from a Matthews bottle (for flushing print heads) into a small cup or bottle.

• 4. Place a rag underneath the print heads to catch drips and protect the paint and fluid lines from damage.

• 5. Dip the provided brush into the cleaning solution.

• 6. Lightly move the brush back and forth across each nozzle, ensuring that all visible traces of ink are gone each time.

• 7. Immediately rinse the brush in the cleaning solution to remove any ink before it dries.

• 8. Place the brush in a sealable plastic bottle or container.

• 9. Using the Brush to Clean • Only use the cleaning solution supplied by Matthews. Do not use water or any other chemical for cleaning. Failure to do so will damage the unit and void the warranty. • Never dip the brush into a cleaner bottle that will be used with the saw. • After cleaning, place the brush in a sealable plastic bottle or container (a wide mouth bottle works well). Dirt must be kept out. • Do not use a plastic bag because the cleaner may eat through it. • It is acceptable to leave cleaner in the brush bottle to keep the brush flexible. • Do not rinse the brush with water. Replace the brush when it is damaged or too dirty to clean properly.

• 10. Practices That May Damage the Print Heads • Do not use a spray bottle to apply the cleaner directly to the nozzles. The spray may push debris into the nozzles and damage the hoses or other components it contacts. • Do not use rags or paper towels on a print head. Using anything other than the brush to clean a print head can push debris into the print head nozzles and create a clog or damage the nozzle.
