When color ink is expended and black ink still remains, you can continue printing for a short time using only black ink. However, you should replace the expended ink cartridge(s) as soon as possible.
Print with black or color ink only

Open the printer driver setup window. From the Page Setup tab, select Print Options. From the Print With: drop-down, select Color Only or Black Only.

Access the print settings in your print application. Click the Main tab. Select Plain Paper/Bright White Paper or Envelope as the paper type setting. Select the Black/Grayscale checkbox.
Go to Control panel and then Devices and Printers. Find and right-click on your printer and click on Printing Preferences. Go to Quick Setup tab and then select Grayscale.
Can you print with one or two empty ink cartridges? The quick answer is: Yes, you can (if you own a printer model that allows it) — but you shouldn`t keep printing with an empty cartridge for too long.
The printer will not operate if a black ink cartridge is expended or any cartridge is removed. If a color cartridge is expended, you may be able to continue printing temporarily with black ink. It`s best to always have extra cartridges on hand.
If using the color cartridge, colors print normally but black prints lighter than usual. You can continue to print until print quality becomes unacceptable.
Go to your computer and click “Print” from the file that you wanted to print. Click on “Properties” and then the “Color” tab next. Select the “Print in grayscale” option by clicking on its checkbox. You can now start printing in black and white.
Thermal printers are common in many machines, restaurants, stores, and medical facilities. Instead of applying ink to ordinary paper, these machines require special paper coated with a heat-sensitive layer. This layer changes color once exposed to heat. Internally, thermal printers are relatively simple machines.
It`s a new type of printer that comes with high-capacity refillable ink tanks, instead of using ink cartridges like a typical inkjet printer. It means you can print thousands of pages without the interruption of frequent replacements. Why do EcoTanks have a higher purchase price?
As long as your printer also has a colour cartridge, all the colours from the colour cartridge will print together to make … BLACK. You`re not going to want to keep it this way forever.
Depending on your computer and printer settings, you may be able to get away with printing black and white with only color ink.
If your machine`s cyan, magenta, or yellow toners run out, you can choose Mono in the printer driver to allow you to keep printing. You`ll be able to keep printing until the black toner runs out.

My 2550n Color LaserJet does not want to print in color
ANSWER : That model had issues with the carousel solenoid sticking. That might explain why it works after you let it sit for 10 minutes. The solenoid gets hotter with use which causes the deteriorated foam on it to become sticky and hold down the release plate instead of letting it go. This allows the carousel to spin when it is supposed to stop for each color. The solenoid is located on the right side of the printer. If you open the lid, it is just behind the opening at the top right. You need to remove the top of the printer and scrape off the goo on top of the solenoid body. I put a piece of thin sticky backed felt to replace it. Other people use electrical tape.
