Pump Operation Test
The procedure below tests whether the pump is pulling ink from the cartridges or not. If this test
proves that the pump is working correctly, the problem may be with the printhead.
1. Turn the printer off, allowing it to perform normal power down procedures.
2. Disconnect the AC power cord.
3. Remove the upper housing assembly. See page 3-7.
4. Release the carriage lock (lever cleaner) to the left of the printhead by pushing it forward.
(See Figure 2-17 and Figure 5-5 below for location.)
5. Manually move the carriage to the center of the printer.
6. Using a straw as an eye-dropper, place several drops of water on the sponge areas of both
caps. (Use enough water to fill the sponge area, but not overflow.)
7. Engage the cam, as shown in Figure 4-1.
8. Move the carriage back to home position.
9. Remove the waste ink drain pad material.
10. Reconnect the control panel.
11. Reconnect the AC power cord.
12. Power on the printer.
13. Check whether the drops of water fall into the waste ink tank. If water drops, it proves
that the pump is operational.
