Half picture when making copy in A4

remove the toner bottle and make around 50 copies but make the copies in A4 LEF but with open ADF and put a white paper on half of the A4 LEF area for to be the copes half white half black. This must be done for the extra toner that is inside the developer unit to be removed. It must be half black-half white for the machine can print the copies, otherwise it will constantly jams. pit the white paper in the right half section of A4 LEF area and make around 50 copies. But do this without toner bottle inside the machine. After the 50 copies end,print a counter and see does it got better. If is ok then return back the toner bottle and the machine will continue to work. If still the copy is bad then make more copies without toner bottle until the image is clear.

I would check to ensure that the page size of both the driver and the printer are set to A4 and not letter. Most HP's will auto sub letter for A4 but if driver thinks paper is letter when it is actually A4 then the printout will not match.

re install soft ware

You apparently are shooting in both jpg and raw modes. I do that. So what you have is actually two pictures. The jpg picture is full screen and the raw (nef) picture has the black lines you describe.

I don't know why it does this other than to allow you to recognize which pictures is raw and which is jpg. It is not a problem and picture quality is not impacted in any way.

Your manual should explain fairly clearly the benefits of both formats. You can use the menu to change it to take only jpg or nef pictures and possibly other formats.

When I edit photos, unless I'm in a hurry, I usually make a copy of the NEF photo and edit that. You can make many more changes in an NEF photo than you can in a jpg photo.

In either case, I would suggest you always edit from a copy to protect the original. I think my D-90 allows the use of other formats in addition to jpg, but nef is the only raw format that Nikon uses.

Try to perform a hard reset for service mode .

Loading the pictures onto your computer simply copies them, leaving the originals on the camera's memory card. To clear the card, format it in the camera by using the format command in the recording menu, as described in the "Formatting a CF Card" section of the manual (page 83 in my copy). If you need a manual, you may download a copy here.

Sir,

Do you have the paper selection in AUTO? Mite you also check your defaults settings

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/normanj_7893313f0751935f

Move envelope/A4 lever near paper output tray until the letter L registers on display. Print in this mode and you should have full page printed.

The waste toner is in the drum unit it's self. If it full you may as well replace the drum unit all togather. Once it is full the drum is just about shoot. If the regestration is off, you may have a problem withe reg. feed clutch. Dose it show up with the paper tray and the manual feed try?

If you mean on the camera, it would be best to copy all pictures with a card reader (the reason is that the camera may not be able to copy corrupted files) and then look through them on the computer. It is possible that file corruption has happened. If that is the case, then you may have to rename them, if the name has changed. What is important to remember is that the file extension has to be .jpg or .JPG for normal pictures in most cameras, there are other file extensions used for larger and other format cameras. The rest of the file name is not that important, unless it means to have your pictures in order.
Also make a copy of the files affected, and rename them with a b or 2 or some way to tell the difference from the other originals.

If you mean on the computer, then make sure to look in the trash folder. If you do not find any files (note as above in the other notes) which have changed names or they are not there, and not in the trash folder, then something else has happened.

This kind of thing can happen if the camera is turned off before the files are written fully to the camera's memory. It cannot save, and thus the camera may not write anything at all to save the picture.

Another thing which you may want to look for is if the pictures could be in the internal memory and not on the card. Remove the card, and start the camera again, if the camera has internal memory. Some cameras have no internal storage ability.
If the pictures were deleted, there is no way to recover them.

As a precaution to preventing this kind of thing, always format the card you are going to use in the camera. Don't change the card to another kind of camera without reformatting it for use in the other camera. If you use a card formatted in another camera, it can cause not only very slow saving, but it can also cause corruption or deletion of files.
As another caution to remember along this line, copy your pictures often from the card or camera and don't let the card or camera get too full, so that you cannot save any more pictures or movie files. If the camera's memory or the card is too full, the camera has no way too save the files, and may cause corruption or other unknown problems. Usually a message will come on the camera's LCD that the camera's memory or the card is too full and cannot save any.
