1. Remove the upper cover as described in Section 4.2.1.4.

easier.)

mechanism. Then move the carriage to the left edge.
4. Make sure both black and color ink cartridges are removed.
5. Fully open the blue plastic covers for color ink cartridge and squeeze the bottom to
release the blue section from the ink cartridge holder. Turn it slightly so the the knob at
the end of the black cover guide releases from the carriage. Repeat for the black ink
cartridge cover.

7. Remove the tension spring 49
