How do I open a Brother DCP-130C printer to get to the head ? -

The magenta tube has just a spot of color the rest of tube is empty.Does any-one know of a site with instructions on how to do this?

Follow the instructions below: 1. Open the ink cartridge cover. If one or more ink cartridges are empty, for example Black, the LCD shows Ink Empty Black and Replace Ink. 2. Pull the lock release lever down and take out the ink cartridge for the color shown on the LCD. 3. Open the new ink cartridge bag for the color shown on the LCD, and then take out the ink cartridge. 4. Remove the protective yellow cap. DO NOT touch the area shown in the illustration below. 5. Each color has its own correct position. Insert the ink cartridge in the direction of the arrow on the label. 6. Lift each lock release lever and gently push it until it clicks, and then close the ink cartridge cover. 7. The machine will automatically reset the ink dot counter. Note: If you replaced an ink cartridge before the LCD shows Near Empty or Ink Empty, the LCD will ask you to verify that it was a brand new one. (For example, Did You Change Blck?) For each new cartridge you installed, press up navigation key or 1 or quot;+quot; to select Yes to automatically reset the ink dot counter for that color. If the ink cartridge you installed is not a brand new one, be sure to press the down navigation key or 2 or quot;-quot; to select No. If the LCD shows No Cartridge after you install the ink cartridges, check that the ink cartridges are installed properly. Caution DO NOT take out ink cartridges if you do not need to replace them. If you do so, it may reduce the ink quantity and the machine will not know the quantity of ink left in the cartridge. DO NOT touch the cartridge insertion slots. If you do so, the ink may stain your skin. If ink stains your skin or clothing, wash with soap or detergent at once. If you mix the colors by installing an ink cartridge in the wrong position, clean the print head several times after correcting the cartridge installation. Once you open an ink cartridge, install it in the machine and use it up within six months of installation. Use unopened ink cartridges by the expiration date written on the cartridge package. DO NOT dismantle or tamper with the ink cartridge; this can cause the ink to leak out of the cartridge.
