Then your waste ink pads are full.
You can follow the instructions below to wash your waste ink pads.
1. Unplug the printer's USB and Power connections.
2. Using a flat blade screwdriver, carefully release the locking tabs
that secure the top of the printer to the bottom. See position of tabs
in the following 3 pictures. Start at the back, then the sides, then
the front. Take care not to break or mark the plastic. Once released,
remove the top plastic cover.
3. Now find the waste ink pads. They are located towards the back of
the printer on the right hand side (looking from the front). The yellow
arrows in the following 2 pictures show the position of the waste ink
pads. First picture is from the front, second is from the back.
4. Wearing rubber gloves and old clothes, carefully remove the waste
ink pads. There are 2 pads, each is about 1 inch by 3 inches.
5. Take them to a sink and wash them using hot water until no more ink runs from them.
6. Dry them, either using the sun, a radiator, or for faster drying time, a hairdryer on low heat.
7. Once they are both dry, replace them where you found them, replace
the printer cover and click the locking tabs back into place.
8. Now connect the printer power supply and USB cable
9. Start the "SSC Service Utility" program again. This time, select the
"Protection Counter -> Reset Protection Counter" option. You'll be
prompted with the following dialog - click "Yes".
10. Check that the counter has reset using the "Protection Counter
-> Show Current Value". If the current value is not zero, turn of
the printer, turn on the printer and repeat step 9. I had to do this
twice to actually reset the counter.
11. Turn off the printer and disconnect the power lead, wait for 30
seconds, and then reconnect and turn the printer on. You should now
have a working printer.
One visitor reported that SSC was unable to reset the counter on his C42. He found a program called "Dr. Tool" that helped to reset the counter.
