MF 733 Color Laser Printer

Hi all,

I have a Canon MF 733 Color Laser printer and for some reason the black print quality is not as dark as it once was.

This just started to happen. When it was new it was perfect. The printer is just over a year old and not used everyday. When I do print something it is maybe 5 to 10 pages.

Any clues as to what is going on? I went into the printing preferences and under the quality tab I chose "General" as the default.

Thanks much,

RIch
