My printer is "imageCLASS" MF4350d and has been working very good for years.
Now it doesn't do print/copy ...any more and says: "LOAD PAPER CASSETTE: LTR"
Yes, neither copy or print, at begining the sound/phenomena is normal, but soon changed
to alarm sound and the red light turning on.
What wrong is the paper cassette causes it doesn't copy .... ----Zhao
