Solution

Precautions when handling the Printhead:

Take the following precautions when handling the Printhead.

For safety, keep the Printhead out of the reach of children.
If ink is accidentally ingested, contact a physician immediately.
Do not touch the Printhead immediately after printing. The Printhead becomes extremely hot, and there is a risk of burns.
There may be ink around the nozzles of the Printhead you remove. Handle the Printhead carefully during replacement.  The ink may stain     clothing.
Do not open the Printhead pouch until immediately before installation. After removing the Printhead from the pouch, install it right away. If the Printhead is left after the pouch is opened, the nozzles may dry out, which may affect printing quality.

Caution

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

Important

Your hands may become dirty during Printhead replacement. Use the gloves provided with the new Printhead for replacement.
Prepare a new Ink Tank when ink levels are low.
When the remaining capacity of Maintenance cartridge is low, prepare a new Maintenance cartridge.

  1. On the Tab Selection screen of the Control Panel, press or to select the Settings/Adj. tab .

  5. Press or to select Replace P.head, and then press the OK button.  Ink begins being drawn in. When it finishes, instructions are displayed on the Display Screen.  It takes about two minutes to complete.

Replace the Printhead:

  1. Remove the Stacker from the printer. (If equipped)
  2. Open the Top Cover.  Instructions are now shown on the Display Screen regarding Printhead replacement.

  3. If the Printhead Fixer Cover or Printhead Fixer Lever is dirty, use a damp cloth that you have wrung out completely to wipe it clean.

Important

Do not touch the Linear Scale (a), Carriage Shaft (b), or Ink Tube Stabilizer (c). Touching these parts may damage them.

 
  1. If the ventilation duct (a) is dirty, use a damp cloth that you have wrung out completely to wipe it clean. Move the Carriage out of the way manually if the Carriage is concealing the ventilation duct, and then clean the duct.


     
  2. Pull the Printhead Fixer Lever forward all the way to open it completely.


     
  3. Pull up the Printhead Fixer Cover to open it completely.

  1. Remove the Printhead and press the OK button.

Important

Never touch the metal contacts of the Carriage. Furthermore, do not allow any dirt or debris to become adhered to the metal contacts of the Carriage. These may damage the printer.

Note   Dispose of the used Printhead in accordance with local regulations.

  1. Holding the new Printhead by the grips (a), remove it from the pouch.

Important

When handling the Printhead, always hold it by the grips (a). Never touch the nozzles (b) or metal contacts  (c). This may damage the Printhead and affect printing quality.

Never touch the ink supply section (d). This may cause printing problems.

 

  1. While firmly holding the Printhead you have removed, use your other hand to remove the orange Protective Part (a). Squeeze the grips (c) of Protective Part (b) and pull it down to remove it.

Important

The inside surface of the Protective Part (a) and Protective Part (b) is coated with ink to protect the nozzles. Be careful not to touch these surfaces when removing the caps.

The Printhead contains ink to protect the nozzles. We recommend removing Protective Part (b) as you hold it over the Printhead package or 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 Printhead somewhere temporarily before installation, do not keep 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 these materials in accordance with local regulations.

  1. With the nozzles facing down and the metal contacts toward the back, insert the Printhead into the Carriage. Carefully push the printhead firmly into the Carriage, ensuring that the nozzles and metal contacts do not touch the carriage.

  1. Pull the Printhead Fixer Cover down toward the front to lock the Printhead in place.

  2. Push the Printhead Fixer Lever toward the back of the printer until it clicks.


     
  3. Close the Top Cover.  Ink now fills the system.  It takes about six minutes to complete.

 

Important

While ink is being filled, definitely do not remove the Ink Tank or Maintenance Cartridge. Ink may leak out.

Note

The procedure is now finished if you have set Rep.P.head Print to Off in the Control Panel menu.  In this case, execute Initial adjustment in Head Posi. Adj. in the Control Panel menu. (See "Adjustment When Installing the Printhead.") Feed paper by following the instructions on the Display Screen.  After the paper has advanced, Initial adjustment in Head Posi. Adj. is executed automatically.

  1. Install the Stacker on the printer.
