Hello all,
Our HP color laserjet 4550n is squeaking badly when printing. I have swapped toner cartridges as suggested in these forums, with no improvement.
I was thinking of purchasing maintenance kit C2001-69012. http://www.printertechs.com/maintkits/lj4kit.php

Is this the right kit for a HP color laserjet 4550n ?

Thanks,
