HP LaserJet Pro color MFP M570 – Color printing.
Toner cartridges are a type of printer cartridge that uses toner powder to produce a print. Cartridges can come in four colors: black, cyan, magenta and yellow.
What must you do before installing a new toner cartridge into a printer? Remove the packing strips. The printer should also be turned off, and the old cartridge should be removed and placed into a sealed bag for recycling. Why is a laser printer better suited to most office printing tasks than an inkjet?
Color laser printers use colored toner (dry ink), typically cyan, magenta, yellow, and black (CMYK). While monochrome printers only use one laser scanner assembly, color printers often have two or more, often one for each of the four colors.
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.
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.
Individual HP ink cartridges

Printers that use individual HP ink usually need a set of four color cartridges: black, cyan, magenta, and yellow.

Your printer should have been packaged with a USB cable regardless of whether it is a wireless or wired printer. Plug the cable into your printer and your computer`s USB port. The direct linking should trigger your computer to recognize the printer and start up the software needed to complete the installation.

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.

HP Officejet Pro 8500 Wireless with fake paper jam
ANSWER : HP Officejet is by far one of the frustrating piece of equipment I have ever owned. I bought it as unused in the package, at that point no warranty left. less than 6 months and 500 pages the white cog gear wheel broke. Luckily with instructions in this site I manage to glue it back together. Then I bought new ink – problems started as they were not original HP 30$ per cartridge. Ordered originals (here in China), took over one week to get them. Then found out that printhead needed to be replaced => more than 100$ spent. Still constant problems: If my wife kids print, I need to be stand-by as you never know what happens. Really an Office level equipment. After cleaning one paper jam I broke the encoder tape, took me another 4 hours to get it fixed. Then broke the cog gear again and got it displaced. Another 4 hours. Only reason I am not throwing this s***t out of window is that there are still ink left. Luckily this drinks them like a horse, for sure I will no more buy new ink. I will get a new laser instead, and not from HP. About cog wheel fixing: make sure that the white wheel is positioned correctly so that the small torx in shaft goes into the slit in the white wheel. When fitting the black cover back, make sure that the white washers on both sides fit into to slits of the black cover. Good luck.
