I have an HP 2550L Color Laser Printer, and I was defrauded when I purchased it. Nowhere on the box or in the sales literature did it say that the printer would stop working when counter chips glued to the toner cartridges and imaging drum reach some arbitary number. Not when the toner cartridges are empty, or the imaging drum produces degraded quality. Just when the counter reaches a number determined by HP, apparently to force you to buy supplies at an increased rate. So when you see the flashing orange light, bend over and smile!
There are three remedies for this fraud.
1) Make HP pay you for the waster toner and imaging drum impressions they force you to throw away. Good luck with that.
2) Reset the counter on you toner cartridges or imaging drum. This sounds promising, but I couldn’t get it to work. If you would like to try though, here’s the procedure (remember this did not work for me, and MAY mess up your printer, so use at your own risk. It had absolutely to effect on my printer, but was claimed to have worked for others):
1 Turn the printer off.
2 Press and hold the GO button (blue-green).
3 Turn the printer on and continue to hold the GO button (about 30 seconds).
4 After the Go, Ready, and Attention Leds all turn on, continue holding until the Attention and Ready leds switch off (GO led still on).
5 Keep pressing the GO button AND now keep pressing the red button (about 15 seconds) until the 3 leds stop blinking.
6 Release GO and red buttons.Reset is done.
7 You may have to re-install HP drivers from CD . You can now continue printing without changing drum or toner.
You may have to follow this procedure many times until you get the timing exactly right. I gave up after 10, and went on the the next option, which did the trick nicely.
3) Buy an after market chip. These will cost you under $10 including shipping. All you have to do is pry the old chip off with a screwdriver, then apply the new self-adhesive chip to the cartridge or drum. Worked like a charm for me, and sure beat paying $200 to replace a perfectly good imaging drum.

I agree with you totally. I have a 2500L that presented with the same problem this morning.
I gave the chip the flick, reset the VRAM as per your instructions, and the blinking yellow light remained, with the addition of the orange light below telling me the imaging drum was not genuine.
Pressed the red cancel button, and VOILA! all lights except the green turned off, and the printer works perfectly!
It is not just HP that rip off customers, they all do it, it is a global consipiracy!
