Precautions When Handling the Print Head

Take the following precautions when handling the print head.

 Caution

  • For safety, keep 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.

 Your hands may become dirty during print head replacement. Use the gloves provided in the box with the new print head for replacement.

 Refill the ink tanks when ink levels are low.

 Prepare a new maintenance cartridge when the remaining capacity of the maintenance cartridge is low‚Äč
