"Very Interesting ... yet quite weird" (German accent from a little (height impaired) German soldier aka: Laugh-In 1960's era) gee, guess I am dating myself.
Anway, to stay on track.... I am intrigued by your 'findings' and will look forward to what you find out.

Through the troubleshooting process of printing my image as colors other than black, I stumbled across a work-around to my situation, although I have no logical explanation for how or why it works.
Noticing that every time I heard multiple cartridges being accessed, I got solid prints, I tried typing a small word at the top of my page. In this case, the word "test" was given a 100% Magenta color value.
Below the magenta wording, I placed my three black logo images.
Printed the page and the black images were solid.
Pressed the images and they were black.
When I try to access the black cartridge, by itself, is when I get the weak and washed out images, which is strange, because I've done that in the past with good results.
Maybe I'm just getting low on black toner and when colors other than black are on the same page, "black" is actually being created by a combination of CMY. <shrug>

David,
I know that I purchased my cartridges before you did. I am still running on the same cartridges. I would be surprised if you are running low, although I know it is all relative to the amount of jobs we have run through the machine. This toner seems to be endless. :-)

Since it is a weird problem, let's look at a weird possibility.
Are you printing in RGB black. CMYK black is not as dense.

David,
I agree. I don't see how it's possible that I could be running low on toner. The last sub cartridge I had in my LaserJet 4m lasted almost 4 years, under fairly regular use.
In fact, I'm seriously considering buying another cartridge for the 4m for "monochrome" printing. The printer doesn't take as long to "warm up" and that way, I wouldn't be tapping out my black 4550 cartridge prematurely.

I like the control over my colors that CMYK sliders provide. I'll have to check which mode I'm printing in.
Whatever the mode, I believe it's the same I've always used, which hasn't been a problem in the past.
