While the pannel power is off, move the heads off the capping station to see those pads you talked about. Below each of the caps (pad area) is a white tube that connects to your capping station from the pump. You will need a syringe with an end that fits into that tube. Get some cleaning fluid into the syringe and remove one of the lines from the capping station. Attach the syringe and hold some tissue around the connection in case it sprays. Gently force some cleaning fluid through the line and into the waste bottle. You might have a bit of resistance while the fluid pushed through the line. You might hear the fluid run into the drain bottle. Do both lines and once they are clear reset the heads back in place ( locked on the capping station). Make sure that the clear lines that run in front over to the little rectangular block, are free if ink. If these are not clear you might need to take them off and flush. This is a bit more work so if it's not needed I won't go into detail.
Then turn on the pannel power and do several cleanings to clear the heads of the mixed ink.
Check your PM for a number to call if you need help.
