I had the same problem, and it seems to have corrected itself. I too, installed a new "45" black cartridge and got the message to remove and check color cartridge. After I removed it and cleaned it the message stayed on the display for about 5 minutes and then asked me to "align cartriges." After I aligned them I had no problems.

"The print cartridge cradle cannot move."
I fixed this problem by disconnecting the power cord from the power-strip and connecting it directly into the wall. My printer was not getting enough voltage from the power-strip. I hope this helps.

Fuser sleeve is contaminated and needs replacing - cheaper to replace the printer.
