Is your fax really able to transmit grey images? I suggest you to scan
in black and white and/or to increase dpi. (Increased dpi will probably
help when hylafax will convert your image to black and white.)

I would also remove option "-m" and add "-G" to your sendfax command.
This will send the 300dpi version if your modem and the receiver are
recent hardware.
