今天印表機不斷出現錯誤，顯示墨水系統錯誤，所以上網找了一下解決方法，Here are the details. Got the Ink System Failure message. The error code shows was '0xc18a0005'. The tech had me press and hold the '*' key on the key pad, then press the '#' key and release them both. Then he had me enter '123' to enter maintenance mode. He then had me press the right arrow (beside the OK button) until System Config. menu appeared on panel. Then pressed OK two times to clear the error condition, then cancel two or three times to return to the top menu. Then powered off and back on, printed a test page just fine, copied a document fine.
