Hi Melissam2505,
Just make sure the printer is turned completely off and is unplugged.
Couple of tips:
- When unplugging the dampers, be sure to pull them straight up. Do not wiggle or tilt them... you will risk cracking the nipples that the dampers attach to.
- Also, be careful with flat ribbon cables that plug into the print heads... try not to pull or roughly bump them around. After the damper swap, I would take a look at the ribbon cables and make sure they are plugged in properly.
After that you can turn the printer back on and do a few medium cleans and test prints till your colors are back.
Easy as pie!
