If the ink level is sufficient, but the printer still does not print black ink, you may need to run a cleaning cycle. A cleaning cycle is a process that cleans the printer heads and removes any clogged or dried ink.
The print head needs to be cleaned or the ink cartridges may be old and require replacement. For instructions on checking and cleaning the print head nozzles, see one of the following Related Articles: How do I use the head cleaning utility in Windows?
Note: To disable automatic black ink switching, press the setup button and select System Administration > Printer Settings > BK Ink Auto Change > Off.
If your Epson printer is printing out faint images, skipping lines, or is streaking your image with lines, chances are you have a clogged nozzle–a common problem many users have with Epson printers. It`s unavoidable that print heads clog over time as small amounts of ink residue dry up and collect in the nozzles.
Here are the most common causes of a printer printing faded text or images: Low ink or toner levels. Toner sticking to the fuser roller or problems with the transfer roller. Low ink or toner density settings.
If your PC or the LCD screen on your printer is telling you that your ink cartridges are full but no ink is passing through to the paper, then it`s most likely that you are dealing with a clogged printhead. Blurry documents and images that appear faded are also signs that it`s time to remove the excess ink.
Reasons for Epson printer will not print from computer

Jammed paper. Ink cartridge issue. No paper is installed. Outdated printer driver.

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.
Even if you select Black/Grayscale or Grayscale in the printer software, some color ink is still being used. Epson printers contain a permanent print head that needs to be charged with all colors to work. Even when you are printing black text only, a small amount of color ink is used to keep the print head charged.
Several factors may cause the product to print blank pages, such as print settings, low ink, or the product itself. Check the following: Make sure the product is placed on a flat, stable surface that extends beyond the base in all directions. The product won`t operate properly if it`s tilted or at an angle.
Even if your cartridge is full and ready for action, it may have become slightly dislodged and no longer in full electrical contact with the printer. The easiest way to rectify this potential problem is to simply remove and reinstall the cartridges.

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.
