Hi
I have a LJ5500 that seems to have a weird issue. When I print the configuration page, the cyan bars on the left side and bottom of the page look wrong, and the darkest yellow swatches on the left side and bottom look orange.
Looking under a magnifier / microscope, the cyan bars on the left side and bottom contain a lot of yellow (and it's more than the yellow printer ID dots), giving the cyan a kindof greenish tint. The cyan swatches contain a little majenta and or yellow depending on which density square it is. The darkest yellow swatch also contains some majenta which gives it the orange look. When I say 'contains some yellow / majenta', I mean under the microscope, they're all clear dots, on a regular grid - i.e. intentionally put there by the printer, not like random toner leaking or something.
Is this normal? Shouldn't the swatches on the configuration page be pure colors? Is there a way to fix this? I've tried resetting factory defaults, and upgrading the firmware (it already had the latest version on it, I just uploaded it again). I've also cleaned the static discharge comb, and taken out the color registration detection unit and verified the lenses are clean. It's like someone uploaded some wrong color correction profile into the printer or something.
When printing the demo page, it looks perfect, but when printing simple vector graphics with solid color areas, the blues and greens definitely don't match the screen colors at all, and are always darker than I think they should be.
