Precautions When Handling the Print Head

Take the following precautions when handling the print head.

• For safety, keep the print head out of the reach of children.
• If ink is accidentally ingested, contact a physician immediately!
• Do not touch the print head immediately after printing. The print head becomes extremely hot, and there is a risk of burns.

• There may be ink around the nozzles of the print head you remove. Handle the print head carefully during replacement. The ink may stain clothing.
• Do not open the print head pouch until immediately before installation. After removing the print head from the pouch, install it right away. If the print head is left as is after the pouch is opened, the nozzles may dry out, which may affect printing quality.

How to Replace the Print Head

• When replacing the print head immediately after printing, wait a few minutes before replacing it. The metal parts of the print head become hot during printing, and there is a risk of burns from touching these parts.

• Prepare a new ink tank when ink tank levels are low.
• Prepare a new maintenance cartridge when the remaining capacity of the maintenance cartridge is low.

   • Do not touch the linear scale (A) or carriage shaft (B). Touching these may cause a malfunction.
     
   • Do not use tissue paper, paper towels, rough-textured cloth, or similar materials for cleaning so as not to scratch the surface.

    • Never touch the ink holes (K). This may affect printing quality.
      
    • The inside surface of the protective cap is coated with ink to protect the nozzle. Be careful not to touch these surfaces when removing the caps.
    • The print head contains ink to protect the nozzle. We recommend removing the protective cap while holding it over the pouch that contained the print head or otherwise safely out of the way to avoid spilling ink and staining your clothes or the surrounding area. If ink accidentally spills, wipe off the ink with a dry cloth.
    • If you need to put a print head somewhere temporarily before installation, do not set it down with the nozzles and metal contacts facing down. If the nozzles or metal contacts are damaged, it may affect the printing quality.
    • Do not reattach the removed protective part. Dispose of the materials in accordance with local regulations.
