I changed a toner cartridge and now it is not alligned and I don't know how to allign it. I have an HP CP2025 and I have tried doing the cleaning and printing the test pages. I don't know what to do now.

I had the same problem and it was the pick-up roller that was at fault. You can buy a new one for less than 20GBP or do what I did. Take the old one out and reverse the rubber. There are plenty of online tutorials on how to change the pick-up roller - the first one you remove. It's a two minute job. Reversing the rubber is easy. Just prize the inner clip out of the roller and put the rubber back on with the shiny side out. It worked first time and no more print errors.

refill ink, lean cartridge contacts or replace catridges

If you changed toner because old was empty and now you have this defect with the new cartrige, it is most likley a defective cartridge. Try the old cartridge again, if it prints clean, then you know for sure it is the cartridge. If you purchased a new HP cartridge, get it replaced by HP, they warranty their toners against defects. If you bought a 3rd party toner, return it to where you bought it and get them to replace it. If you had your old toner refilled by someone, get your money back, they don't know what they are doing. This type of defect is often caused by a filled waste toner bin then then runs back out when you print. Some refillers just throw toner in and don't empty the waste toner bin.

Replace the cartridge.
The gears are the same for all the cartridges.
If it is a new cartridge, try to get it replaced.

TONER CHIP on CP2025 printer:
This resource may help
http://resources.lasertekservices.com/hp-smart-chips-overriding-this-lockout-mechanism-with-reset-chips/
Gives types of chips to use, sales in USA, and certain things to take note of.
The toner reset chip replaces the original HP ID chip and is designed to be used only on refilled HP cartridges.
It is not recommended to force toner cartridges to run on empty, as this can cause damage to both the printer and the toner cartridge.
The reset chips are dedicated to one color only, so that user can not swap toners.
As for actual physical installation, just push the new ID chip in until it clicks into place. The correctly manufactured ones should be a snug fit.
I have seen techs using a drop of contact glue behind the chip-board to secure it.
Copper pads face outwards towards matching printer pins.
See photo for polarity 'square' pad.
My printer is Samsung, not HP, so your toner cartridge may be a different shape.

1. Open the printer and remove and reinstall the same cartridges again (important)
2. Ensure paper is loaded and the paper slider is correctly positioned against the edge of the paper
3. When asked to allign, do so again

Hope this helps!

the page should be absolutely new.and the scanner glass should be absolutely cleaned.and 1 main thing u replaced your black cartridge.but if your colour cartridge is empty it will not accept the allignment complete thing.it will show allignment failed as the particular colour is missing in your allignment sheet which is required to get the allignment complete.
