LaserJet 3550: override chip on toner cartridge to continue print
I would like to override the cyan cartridge inside my HP LaserJet 3550 color printer. It's not even close to empty but the microchip is refusing to let me print (in any color). I've read that, using the printer's menu, I just need to go through "Menu">"Diagnostics">"Disable Cartridge Check". Unfortunately, although I can see this option, I can't select it. (When I click the green check button, the menu system just reverts back to the main menu which tells me to "Replace Supplies".) Can someone tell me how to overcome this problem?

Very few printers will print if they're out of toner, even if the colour toner is exhausted and the print job is only black. Replace the empty toner and if this is the only problem, the printer will continue printing.
The 3550 won't print in any color if any of the colors are out. You'll have to replace the color ink that's empty to get it to print.
In the future, if you're just printing black and white, you can select "Print in Grayscale" from the print properties to just use the black ink cartridge, which will help the color cartridges to last longer.
There is an override sequence and it works well. Press the select button (checkmark) to indicate Main menu. Press right-arrow (RA) to select System Setup. Press Select , then RA to Print Quality, Hit select. RA to Replace supplies and hit Select. Now, RA to Override Out and Select. Confirm with Select again. Your 2600n will now run even with an empty toner cartridge.
Cause from the sounds of things, youre having cartridge problems, Cyan is faulty "blue background" replace with gen. If the black is recycled/non HP then that will be your ladder problem too., If you are in fact using HP let me know and I will tell you how to isolate your fault further ie you have a fuser or transfer belt fault.
Do you use original genuine cartridges or refilled ones. It sounds like you have had a leak and need to completely clean out your printer heads, rollers and perhaps do a deep claean as well. You can buy faulty cartridges and toners that have one leak, then the ink continually leaves traces as it prints. When you say callibrated, do you mean you ran print tests and setting tests. Running a print test can often help to diagnose ink issues an d narrow the results down a bit. After a thorough clean, you could try uninstalling and reinstalling unit.
