A printer your business can depend on

If you want professional quality prints, an HP LaserJet Pro Color Printer can be the solution to your needs.

From the Home screen on the printer control panel, select the Reports menu. Select the Configuration/Status Pages menu. Select Supplies Status Page, and then select Print to print the page.
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.
Laser printers, unlike inkjet printers, do not use ink cartridges. Instead laser printers use toner cartridges, so be sure to purchase accordingly depending on your printer. Toner is a fine dye power that is melted onto the paper.
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.
Laser printers use toner powder instead of dye or pigment-based ink. Laser printers produce electrostatically charged dots on a light-sensitive drum which attracts toner powder. The toner is transferred to the paper and fixed by a heating process. Laser printers deliver crisp black and white and brilliant color prints.
Select the Start button, then select Settings > Devices > Printers & scanners . Under Printers & scanners, look for your printer. If you see your printer listed, you`ll know it`s installed.
A Configuration Page lists the current settings of a printer, the optional accessories installed, and useful information to help troubleshoot printer issues.
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 504 Gateway Timeout error is an HTTP status code that means that one server didn`t receive a timely response from another server that it was accessing while attempting to load the web page or fill another request by the browser.
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. The ink levels may be low and you may need to refill the ink.
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.
Laser Printers work with CMYK toners only. inkjet printers and ink printers used for professional photo printing, for example, can use additional colors to achieve better printer results. Among other things, brighter gradations of magenta, cyan and also gray are used.
Toner cartridges work with laser printers. Monochrome laser printers use just the black cartridge and only print in black. Color laser printers use all four cartridges and can print in black and color.
HP fills their ink cartridges with either pigment-based ink or dye-based ink. Pigment-based ink is commonly used in their black ink cartridges because it is better at printing text. Dye-based ink is often used in their color cartridges because it is better at creating the vibrant colors required for photo printing.

When RGB files are converted to CMYK to print on a four-color printer, there are generally color shifts. Usually these shifts are minor, but they can be an issue, especially if your project is color-sensitive. Similarly, if you upload a CMYK image to the internet, you may also see color shifts (Example Below).

What repair needs to be done for a "50 needs repair" message on an HP Laserjet IIIP?
ANSWER : I don’t know what you mean by good toner cartridges. They haven’t been built in about 10 years, so if they are new OEMs in the box, they are guaranteed to fail. The 50 error on that printer is mostly a burned out fuser lamp. This site was sold, so as you can see, there are no more kits available.
