My picture is too dark i want to make lighter

Try going into the printer set-up and adjust the print darkness to lighter.

ink in the cartridge wastage is full. empty the wastage and check it.

You never should use the picture you see on the monitor of the camera. Not one camera has a calibrated screen. And the brightness is changed very easy in the setup menu.
To test if your camera shoots good pictures, select AUTO on the mode dial. Shoot some pictures and look on the PC or just print them.
Your camera has so many settings, that over rule the brightness when you switch to it, like + and - 2 EV setting. But when you chose for A, P, S, or M, the pictures can be to dark or to bright, if you dial in the wrong settings. So don't evaluate the pictures on the monitor. Only use the histogram on your camera to see if you have a correct, to dark or to light picture.

ic circuit is the problem, see TV Tech.

go into printer properties and change the setting....you probably are using an after-market cartridge...they are notorious for being too dark....even if that is not the case, go to printer properties and change the setting....if there is no slide bar for heavy to light, then clik on toner saver, it should print lighter than it does now

Looking down at the top of the camera, check the left knob. This is the exposure compensation dial. Adjust it to "0". If set one way or the other, it will make pictures darker or lighter. This comes in handy when the image has a lot of dark or bright areas - moving this dial will allow you to make the bright areas darker or the dark areas lighter when you camera's light meter is setting the exposure in a way you do not want.

If still having trouble, make sure the right knob (Mode) is not set to M or Manual. Switch it to Program or Auto and try taking a picture again. You might even want to set the outer knob (ISO) to AUTO as well to reduce the chances of an incorrect setting. If it now works as expected, but you want to shoot in M, you will need to learn how to use the meter to select the correct combination of aperture (f stop), shutter speed and ISO to obtain the desired results.

Oh, experiment with the exposure compensation knob when you have a chance, learn how it can help correct overly dark / bright scenes. Good luck!

look at control panel printer properties of the printer ur printing to. See if there is a setting for
"picture quality" you may be able to adjust from there. If not depends on the picture editing software that ur using most all have "contrast" "brightness" slide bars that will alter picture viewing and printing

try cleaning the print-heads from printers menu
you probably have a goggled print-head

the ccd imagery sensor is bad.will have to be replaced to work correctly.

You did not say what sensitivity setting you had the camera set at- the higher the sensitivity the lighter the picture. Actually- all the image information is there so all that needs to be done is to edit the image lighter in a graphics editing program[You did say whether or not you import images to a computer] Come back back with more info on what you do with the images.
