I have replaced original Magenta toner cartridge Q6003A. My laser Jet 1600 does not recognize it and keeps asking for replacement. What is the problem?

The error 51.2M is a laser error on this printer. M indicates that it relates to the Magenta toner cartridge. If the reset below does not work then you need to call HP support or just get a new original Magenta cartridge and it will work. A cold reset might resolve this issue if the printer does not have a laser hardware error.
I have provided the steps below to help you perform the steps.
Caution: The printer settings will go back to the default factory setting.

1. 1. Press the green (Select) button to continue.
   2. Turn the printer off.
   3. Perform a cold reset.
      1. Turn the printer on.
      2. Watch the control panel.
      3. When the memory starts counting, press and hold the green (Select) button.
      4. Continue holding the green (Select) button until the Ready, Data, and Attention lights flash once, and then stay on steady.
      5. Release the (Select) button when the Ready, Data, and Attention light are on steady. The control panel will display SELECT LANGUAGE.
      6. Press (Down Arrow) button once. The control panel will display COLD RESET.
      7. Press (Select). The printer will perform a cold reset and then continue its power-on sequence.
   4. If this message persists get a new Magenta Toner cartridge or contact an HP-authorized service or support provider.

Magenta Toner cartridge Problem (Q6003A), Put a new one.

I know the frustration being in IT for over 20 years working on various peripherals.
These printer MIX so that way there is a balance at the final phase. You have to purchase a magenta cartridge to get this working again. Bypassing this will make tis printer suffer and long term damage can cause a economical issue on your end in the long run.
Now if your at a critical point you can bypass but I do not professionally recommend this but here it goes.


1. Open the CP1210 Series Toolbox 2. OPEN System Settings 3. Then enable Cartridge Out Override 4. Then click apply
I hope this works for you, whilst you purchase a magenta toner. Please do not forget to leave a positive rating and feedback.

Best of Luck

Replace it for a new one (Q6003A) Magenta toner cartridge.

Unfortunately laser printers don't work this way. The laserjet 1022 was designed for black and white prints only. In order to do color printing with a laser printer you will need to purchase one that is designed to print in color. The laser printers work a bit differently than the inkjets - the laser printers have 4 toner cartridges, one each for Cyan, Magenta, Yellow, and Black, that work together to print a full color page. With the old inkjets you could just replace a black cartridge with a color one.

So, short answer: Sorry but no you can't make a laserjet 1022 print in color. :)

I would recommend looking at an entry level color laser printer from hp, such as the CP2025 (http://h10010.www1.hp.com/wwpc/us/en/sm/WF25a/18972-18972-3328060-15077-236268-3673580.html) if you are looking into purchasing a color laserjet.

Hope this helps

Try removing, and then reseating the MAGENTA cartridge.

If you replace the MAGENTA toner-cartridge, does the problem go away?

that fault due to scaner problem .
u have to change scaner printer.

When you take the toner cartridge off the imaging unit, is there magenta toner in the open slot of the IU? Assuming that there is nothing wrong with the toner cartridge, you are possibly looking at a bad engine control board.
