How to Identify and Fix Common Problems ?

Click the Paper/Quality tab, and then locate the Quality Settings area. If the entire page is too dark, select the EconoMode setting. If the entire page is too light, make sure you are using the correct setting for the print job. If you a printing photos, select the Photo option.
Check the toner darkness settings.

Sometimes light print can be remedied by simply changing the toner darkness setting in the printer. To change the setting, go to MENU>>SETTINGS>>QUALITY MENU>>TONER DARKNESS. Increase the darkness and send a test print to see if that fixes the issue.

You can make prints lighter or darker by adjusting the print density setting in the printer driver`s dialog box or the RJ Utility. -5 is the lightest, and +5 is the darkest.
Prints appear too dark.

The main reason this occurs is because the brightness level on the computer monitor is too high. It`s common with newer monitors, many of which are designed for gaming and have their brightness levels set higher by default.

Monitor brightness

Simply dimming your monitor until it matches the brightness of the print is only a band aid for the dark print problem, but if you`re just an occasional photo dabbler, it might be all you need. If the monitor is dimmer, all your edits will revolve around making a brighter print.

If the next page you print is darker, that means that your printer is low on toner density. Next, try replacing a light printing toner cartridge with a fresh one. If you swap toner cartridges and your printer is still printing too lightly, then the issue isn`t just an empty toner cartridge.
Whichever direction you`re coming from, it`s important to understand that toner will not make your hair a darker color.
Wash your hair with clarifying shampoo.

A clarifying shampoo cleans your hair deeply, removing dirt, oil, and product buildup. If you are unhappy with how your toner turned out, the good news is that toner will fade in time. You can speed up this process a bit by washing your hair with a clarifying shampoo.

On your computer, in the Windows Notification Area (bottom-right corner of your Windows desktop), right-click the printer icon. In the printer menu, select the Properties or Preferences option. In the printer settings window, the ink or toner levels are displayed for the currently-installed cartridge(s).
Print density is the measurement of light reflected off of the substrate, or how dark the print appears after each press strike. When looking at the definition of print density it is easy to see how the materials that come in direct contact with the printing surface play a crucial role in print density quality.
CMYK is a subtractive type of colour process, meaning unlike RGB, when colours are combined light is removed or absorbed making the colours darker instead of brighter. This results in a much smaller colour gamut—in fact, it`s nearly half that of RGB.
You can use photo editing software to brighten up a dark photo for printing. For best effect, adjust the brightness and contrast in the photo until the white parts in your photo appear pure white. You can adjust the brightness and contrast with most photo editing software.
Faint, streaky or spotty prints are all common signs of a clog but a simple cleaning can usually get your HP ink cartridges working again. Printheads clog due to infrequent cartridge use. If you regularly go a few weeks without printing, your cartridges will eventually dry out and need to be replaced.
In four-color press printing, black is achieved by mixing cyan, magenta and yellow and then adding black ink on top of that. The result is a rich, deep black color.
If you find your photos to be too dark or too light it`s because of incorrect exposure. Exposure is the amount of light that gets into your camera and produces the picture on the image sensor. If a photo is too dark it means it has been underexposed and if it is too light it has been overexposed.
If you are outputting to an inkjet, laser, or large-format printer, images should remain in RGB.
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.
Open a document to print on the computer, and display the setting screen of the printer driver from the print menu in the application. Click [Print Quality:Standard] of the [Detailed Settings] tab. Select [Advanced Settings] in “Adjust Image Quality/Color”, and then click [Details…].

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.
