Wrong firmware installed in HP LJ 3050

I am very sorry to have to be the bear of bad news. Usually doing a failed firmware update (or wrong firmware version) you have to return to factory or have a local computer printer shop that deals in HP printers repair this firmware mixup. There is sometimes a firmware recovery mode that can help however You would have to contact HP and ask them how to get into firmware recovery mode.
Sorry hope this helps answer your quesiton.

HP Color LaserJet 2600n Printer - Installing Print Cartridges When a print cartridge approaches the end of useful life, the control panel displays a message recommending that to order a replacement. The printer can continue to print using the current print cartridge until the control panel displays a message instructing to replace the cartridge. The printer uses four colors and has a different print cartridge for each color: black (K), cyan (C), magenta (M), and yellow (Y). Replace a print cartridge when the printer control panel displays one of the following messages: Replace yellow cartridge, Replace magenta cartridge, Replace cyan cartridge, Replace black cartridge. The control panel display also indicates the color that should be replaced (unless a genuine HP cartridge is not currently installed). Change the print cartridge
  1. Turn off the printer.
  2. Open the front door. c00315320.gif CAUTION: Do not place anything on the transfer belt (ETB), which is located on the inside of the front door.
  3. Remove the used print cartridge from the printer. c00315321.gif
  4. Remove the new print cartridge from the bag. Place the used print cartridge in the bag for recycling. c00315322.gif
  5. Grasp both sides of the print cartridge by the blue handles and distribute the toner by gently rocking the print cartridge from front to back. CAUTION: Do not touch the shutter or the surface of the roller. c00315323.gif
  6. Remove the orange shipping locks and the orange shipping tape from the new print cartridge. Discard the shipping tape and shipping locks according to local regulations. c00315324.gif
  7. Align the print cartridge with the tracks inside the printer, and using the handles, insert the print cartridge until it is firmly seated. c00315325.gif
  8. Firmly close the front door. c00315326.gif
  9. Turn on the printer. After a short time, the control panel should display Ready.
    NOTE: If a cartridge is in the wrong slot or is the wrong type for the printer, the control panel will display one of the following messages: Incorrect yellow, Incorrect magenta, Incorrect cyan, Incorrect black.
  10. Installation is complete. Place the used print cartridge in the box in which the new cartridge arrived. See the enclosed recycling guide for recycling instructions.
  11. If a non-HP print cartridge is in the printer, check the printer control panel for further instructions.
    NOTE: When replacing or changing a black print cartridge, a cleaning page will automatically print. This helps prevent speckles on the front or back of printed documents. A cleaning page can also be generated using the control panel or the HP Toolbox.

Memory error

Just do 2 steps:

1. Press Stop.
2. If the display highlight "Resume". Press the OK (Check Button).

The display will tell you that a Non-HP Cartridge is installed and Economode is Disabled.
At least, you can now print. The display will show back again to "Ready".
