HP EasyColor scans documents and automatically adjusts photographic images in . JPEG or . PNG format. Rather than dividing an image into several pieces, HP EasyColor technology enhances the entire image at one time, which results in improved color consistency, sharper details, and faster printing.
Any of these error codes (51.2c , 51.2m , 51.2y , 51.2k) points to a failure with one of the laser scanner assemblies on the HP Color LaserJet 4600 series. To solve this error code, replace the corresponding laser scanner.
The error is indicating that there is a Magenta Laser problem that needs to be resolved by service. You will need to contact an HP-authorized service or support provider.
The basic colours are cyan, a combination of blue and green; magenta, a combination of red and blue; and yellow, a combination of red and green. Many ink makers and printers call cyan “process blue,” magenta “process red,” and yellow “process yellow.”
Monitors display colors by light pixels using an RGB (red, green, blue) color process, but printers print colors using a CMYK (cyan, magenta, yellow, and black) process.
That error code indicates a failure of the yellow laser scanner. Unplug and leave for a few minutes, also make sure you are plugged directly into the wall and not into a surge protector.
If one or more toner cartridges are installed incorrectly, this may result in a 54.2 carousel rotation error. This error is typically accompanied by a loud grinding noise. NOTE: The carousel is the rotating part under the top cover to which all four print cartridges attach.
57.1 , 57.3 , 57.4 , 57.5 , 57.6 , 57.7 , 57.8 Error HP LaserJet 9000 9040 9050. Any of the 57 errors on the HP LaserJet 9000 , 9040, and 9050 series printers are fan errors. There are 7 fans in the machine. Replacing the corresponding fan usually cures these errors; fans are a common failure part on this model.
59.10 is a main drive error, which could be a bound up fuser. 51.10 is a laser error, which could be a bad laser unit. Which error do you have? If the printer can print an engine test, then you may have a bad formatter.
CMYK – Print

CMYK stands for Cyan (C) – Magenta (M) – Yellow (Y) – Black (K). This is a process of printing using varying levels of the 4 aforementioned colours and the majority of the world`s printing uses CMYK. Most printer ink comes in those 4 colours. It`s used for digital printing and a lot of publishing.

The “four-color” in “four-color printing” refers to the four ink colors—cyan, magenta, yellow, and black (CMYK)—used in offset printing presses and many digital presses. These four colors are combined to make a wide range of colors.
The official HP colors are HP Blue, black and white. We recommend using the HP color palette for personal projects and in the case of commercial use to visit the company website.
When it comes to RGB vs. CMYK, what`s the difference? Both of these color modes mix colors to create different color possibilities. The main difference is what they are generally used for in design: RGB is the color mode best for digital designs and CMYK is best for printing.
To avoid this disappointment, printers told designers to convert colors to CMYK so they`d see them more accurately on their computer. Now, modern workflows allow printers to use color profiles that automatically match CMYK ink to RGB values to produce results that are much more similar.
HP Easy Scan is a free application for select desktop and notebook computers that allows users of HP multifunction printers and scanners to manage incoming documents.

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.

HP Color Laserjet blank pages – only jetdirect page
ANSWER : What about the engine test? To do that, drop down the front tray. Feel around on the left side at the top and you’ll feel a little plastic dongle. If you lift up on that it will initiate an engine test page. That will be a page containing lines of each color.
