How to Identify and Fix Common Problems ?

The ink cartridges may be old or low on ink, and you may need to replace them. Your printed colors can never exactly match your on-screen colors. However, you can use a color management system to get as close as possible. Try using the color management options in your printer software.
Sophisticated computer chips inside the inkjet printer convert the electronic image data into precise instructions that are sent to the print head, which in turn communicates with the ink cartridges to tell them exactly how and when to produce their tiny droplets of ink.
Check Cables and Printer USB Ports

Check all cable connections (including the power cord) on the printer side. If the printer does have power and you`ve properly connected the communication cable, but the printer is still not recognized, try switching to a different USB port on the PC.

Press your printer`s Setup button. Go to System Setup. Choose Print Quality and then Calibrate Color. Choose Calibrate Now and press OK.
A common cause of faded, faint printouts from your inkjet printer is dried ink particles causing a blockage in your printer. The printheads on an ink cartridge can be become blocked if the printer is not used for a period of time, so it is recommended to print a few pages each month to maintain the print quality.
Print color mismatch refers to a shift in the positions of colors that may occur when printing one image with multiple toner cartridges, causing printouts to appear blurry.
Simply put, CMYK is the color mode intended for printing with ink, such as business card designs. RGB is the color mode intended for screen displays. The more color added in CMYK mode, the darker the result. The more color added to RGB, the lighter the result.
Because there are no methods for printing in RGB, no matter where you print you must convert your project to a printable format (CMYK). This is a crucial step in the printing process and affects how well your colors are represented in the final product.
RGB is used in electronic devices, like computer monitors, while printing uses CMYK. When RGB is converted to CMYK, colors can look muted. Designers were often disappointed when their printed piece looked different than what they had been seeing on screen.
In some respects, the signs that your printer has been infected with malware are similar to the general signs of a malware infection on your computer, the signs include unusual behaviour by your printer, such as not responding to your commands, printing unauthorised print jobs and refusing to install security updates.
Clean the printheads: Sometimes the issue why you are unable to print in color is because our printheads are clogged with ink. Clean the printheads and then print a document to check if color printing works. Some printers also have in-built programs that can clean themselves so remember to check for that.
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.
Your printer may be printing pink as the other ink cartridges have run out. Common printer-to-page technology processes colour in four parts; cyan, magenta, yellow and black (CMYK), or toner. The ink cartridges in your inkjet or colour laser printer are split up into four colours.
Poor print quality is the most common complaint people have about inkjet printers. These problems often show up in the form of horizontal white lines running through each line of print. If you run into these types of issues, you can sometimes fix them by cleaning the print head.
CMYK printing is also called the colour separation or four-colour-process. The colours are individually applied, starting with black, and then the rest of the process colours are applied in the order- cyan, magenta and yellow.
Just above the circuit board on most printer cartridges, you`ll find a small button. You`ve seen these tiny buttons before on cell phones, phone chargers, etc. This is your reset button, and the only way to get in there is either with a paper clip or the tip of a pen (which will leave a tiny ink smudge on the button).
Because the RGB scheme has a greater range of colors, CMYK cannot produce brighter colors. These hues are beyond the CMYK range and will come out darker and more dull when printed than what you see on your display.
Conclusion: CMYK Produces Superior Color in Printing

Ink on paper must use the CMYK color space to achieve the optimum results by creating an unlimited number and shades of color. CMYK will produce full, dark, rich and vibrant colors to bring your project on paper to life!

Keep in mind that most modern printers can handle RGB content. Converting to CMYK early won`t necessarily ruin the outcome, but might result in the loss of some color gamut, especially if the job is going on a digital press such as the HP Indigo or a wide-gamut device such as a large format inkjet printer.
Why is RGB not ideal for Printing & Packaging? In most printing processes, RGB color space is usually converted to CMYK before creating the artwork. Essentially, any colors produced with RGB on the digital space will not create the same output on the physical print.
To create a new CMYK document in Photoshop, go to File > New. In the New Document window, simply switch the color mode to CMYK (Photoshop defaults to RGB). If you`re wanting to convert an image from RGB to CMYK, then simply open the image in Photoshop. Then, navigate to Image > Mode > CMYK.
The combination of RGB light creates white, while the combination of CMYK inks creates black. Therefore, it is physically impossible for the printing press to exactly reproduce colors as we see them on our monitors.
Therefore it is not possible to use the same additive RGB color system for printing. As a result, CMYK has a smaller color gamut than RGB. It would help if you remembered that it is impossible to print bright red, bright green, or bright blue colors (and neons, too) with the CMYK color model.

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.
