HP Color LaserJet CP2025N
We have an HP LaserJet CP2025N that printed with distorted colors. We replaced all of the cartridges, now all the colors print better except for the red. The red color prints a faded reddish pink. We tried replacing that cartridge with one from another printer that prints fine (same model) and it still prints faded. Any ideas what to check next? Thank you in advance for your help.

Upon further investigation, it appears that all of the colors are faded. I have the same printer so I am able to compare output and my colors are much more vivid.

How to Identify and Fix Common printer Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced technical support :

It could be the wrong printer driver being used, wrong driver settings, toner cartridge colors not being the right color shades, printer color needs calibrated, the computer monitor you`re using is out of calibration.
Pinks in CMYK printing are all about the magenta. For stand out pink colors – the magenta levels should be high, and the yellow, cyan, and black low.
Make sure that none of the ink cartridges are empty. If the cyan or yellow run out, you`ll get a definite red/pink hue to the printouts. – Verify that the paper type setting in whatever application you`re using, matches the paper type you`re using.
To make red, magenta and yellow inks are used, since magenta absorbs green light and yellow absorbs blue light, resulting in only red light being reflected back to our eyes. If you`ve ever used different colors of paint on a palette, you probably understand the basic mechanism of color printing.
If your printouts have incorrect colors, try these solutions: Make sure the Black/Grayscale or Grayscale setting is not selected in your printer software. Run a nozzle check to see if any of the print head nozzles are clogged. Then clean the print head, if necessary.
Why is my printer printing yellow not red? It is most likely that your image is yellow where you were expecting it to be red and you may also notice that blue parts of the image appear turquoise instead. Both of these effects are caused by a lack of magenta ink/toner on your prints.
Information about Pink / #FFC0CB

In a RGB color space (made from three colored lights for red, green, and blue), hex #FFC0CB is made of 100% red, 75.3% green and 79.6% blue.

The ink levels may be low and you may need to refill the ink. Visually check the ink levels. Also make sure you filled the tanks with the correct colors of ink. After you print, the colors in your printout need time to set as the ink dries.
Check the print job settings: From the application you are printing from, click File > Print, and then click Options, Printer Setup, or Preferences, or open the Paper Type/Quality or Media & Quality menu. Make sure the color, paper type, paper size, and quality settings are correct for your print job.
The CMYK values of pure Red are 0% Cyan, 99% Magenta, 100% Yellow, and 0% Black (highlighted in green within Figure 1).
The reason printing uses CMYK comes down to an explanation of the colors themselves. CMY will cover most lighter color ranges quite easily, compared to using RGB. However, CMY by itself can`t create very deep dark colors like “true black,” so black (designated “K” for “key color”) is added.
The color which the eye sees is the color given by the wavelength of light which is reflected off the material. For example, a red pigment appears red because any wavelengths which do not correspond to red are absorbed and the wavelengths of light corresponding to red are reflected off the material.
Prints that appear more green are commonly caused by an absence of magenta ink/toner being put to paper by your printer. In addition to your prints looking “greener” you may also notice yellow and blue areas appear almost neon due to the the magenta not being able to give them more realistic tones.
Reds print, as orange, but they are Red. This problem could be caused by “out of gamut” viewing, usually caused by oversaturation of the color. Try printing in “Relative Colorimetric” as the easy fix. If that doesn`t work, try lessening the saturation levels.
If you run out of yellow, you end up with red and blue which would give you purple. Bottom line – check your ink to see if you don`t need to replace one or more cartridges.
Saving a file as RGB for print can sometimes impact on the way certain colours are printed meaning you won`t get the finish you are after. Most printers will convert your RGB file to CMYK but it can result in some colours appearing washed out so it is best to have your file saved as CMYK beforehand.
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.
Two colours, red and white make pink. Simple.
The RGB values for Sherwin Williams HGSW1067 Prettiest Pink are 244, 200, 197 and the HEX code is #F4C8C5.
A light color is a tint. For example, pink is a tint of red. A dark color is called a shade. Forest green is a shade of green.
Ink or toner: If the printer`s red ink or toner cartridge is low or empty, it may not be able to print red. Check the ink levels and replace the cartridge if necessary. Blocked nozzle: Sometimes, the nozzle that dispenses red ink may become clogged with dried ink or debris, preventing it from printing properly.
First, check your printer settings on the file or picture your trying to print. If your page is setup to print in “grayscale” it will only print in black and white. Change the setting to “default” so it will print in color. If your settings look good from the start, the cartridge may just need to be primed.
Reasons why your HP printer has ink but won`t print

This may seem obvious, but it sometimes happens: first make sure your paper tray has paper in it. Misalignment, clogged printheads, faulty data communication or insufficient ink levels can also be sources of the problem.

For RGB it`s red, green, blue. For CMYK it`s cyan, magenta, and yellow. RGB is an additive process using colored light, and CMYK is a subtractive process using the pigment of inks, dyes, or paint. These two systems are fundamentally different– you can call them opposite– so it`s important to know the difference.

My pictures print almost all red
ANSWER : At first, try printing the internal demo page of the printer. You will find this under the “Information” Menu. If this page prints ok, the problem is on your computer. Maybe the driver or some application settings. Almost impossible to diagnose from far. Look for a “Reset to Default”-Setting in your driver. You may delete the printer and re-install it with the most up-to-date Driver from OKI. Since the printer is an old one, you may have to look for a “Vista-Driver”, when you’re running Windows 7/8. OKI does not not supply any drivers beyond Vista. I could not find anything about mac drivers …

Print file sent but no printing occurs
ANSWER : Been working on these since they first were released. Never seen a problem like yours. If it happens again, try doing an engine test, as it bypasses the formatter board. The engine test is located at the right side of the manual tray opening. Look for a hole in the side wall. Stick something like a paper clip into it to actuate the test button. It will then print a lined test page. If it does that, then it points to the formatter board as the cause of your problem.

Prints blank pages, won't print from computer
ANSWER : Don’t know why you replaced the fuser, but assuming you had print before, then it must have been something you did during the procedure. Only thing I can suggest is to recheck your work. Just because you reinstalled a connector doesn’t mean that it is seated firmly enough to work. Any flat ribbon connectors that you removed and reinstalled, check to see that the contacts are all flat and not peeled back.
