Error 5C00 on Canon iP90 (by 3 users)

i took out both printer cartriges then put them back in. there was a window that asks if you replaced the cartriges; click yes then click on the black and color boxes indicating you replaced (re-inserted) both cartriges. for me the light stopped blinking (previously, it was blinking orange 4 times). next i tried to print but only yellow and black appeared. i then cleaned the head 2 times.

to clean:
-go to control panel
-click on printers
-click on printers and faxes
-find your printer, right click on it
-click properties
-find the maintenance tab
-click cleaning
(clean a couple of times if needed)

hopefully it works...
