My printer doesn't print everything i tell to it

[Ali142]

URGENT!!!

My printer doesn't print all what i tell to it to do. I haven't used it for a lot of time and i don't use it a lot. The little times i give it the order to print it doesn't print all the lines of test i told it to do.

I tried to clean it, using cotton and warm water, after watching on youtube how to do it. This didn't help.

PLEASE HELP ME, I DON'T KNOW WHAT TO DO AND I REALLY NEED IT!!!

Do you get the same results if you print a copy?

[Ali142]

Yes, the same result. It doesn’t print everything just some pieces.

Did you also change the colour cartridge?

If yes then you have a hardware problem with the printer.

Is the warranty over?

[Ali142]

I tried changing both cartridge but still nothing. Yes, the warranty is over... If it’s a hardware problem I can’t fix it?

Have you tried printing in single cartridge mode?

[Ali142]

Yes, I have. I tried putting only black and white but still nothing.
Thank you very much for trying to help me, I am very grateful. By the way.

One last thing that you can try is a reset of the printer using the front buttons.

I do not know the steps for this printer but Google should be able to find a answer.
