PRINTING IS DARK

THE PRINTER AT WORK IS PRINTING DARK BLACK LINES ON THE PAPER WHEN IT PRINTS. WE HAVE CHANGED THE TUMBLER AS WELL AS THE INK & STILL THE SAME PROBLEM. WE HAVE ALSO CLEANED OUT THE INSIDE BUT NOTHING HAS CHANGED. DOES ANYONE KNOW WHAT CAN BE CAUSING THIS & HOW TO FIX IT!! SOMETIMES THE WHOLE PAGE IS DARK...IT IS VERY FRUSTRATING!!!

Dark copies (whole pages) are usually a result of poor charge of the drum. Drum is that green thing (usually, seen blue ones too). You get text and graphics in places, where the drum has been discharged (light discharges drum). So if everything is dark - the drum is discharged fully, or not charged at all. Look for bent, dirty or missing connector plates, springs, paper covering contacts. If you get lines it could also be the fuser (hot thing) - needs replacing. Everything depends on how the copy looks like, I would have to see it. Hope this is helpful somehow ;-)

Mfc 6490cw print is lightly black so print is not good whot is probalem


Black is very difficult for an ink jet printer. If you are using the wrong paper, it even is more difficult. Please use paper made for ink jet printers, because the paper can absorb the fluid better so the pigment is more visible. There are also different ink's you can buy, but please if it really should be black, only use the brand own ink. Not a cheaper version. Professional printers even use different blacks for photo paper and for matte paper (and ink jet paper). Just to microbe how difficult it is to get real dark black on different media.

I want to print in white ink on black paper. I have a Canon MX310 printer


Inkjet printer inks are dye-based, and that's the reason.

Perhaps this will help explain things. You know those little boxes of food colouring you can buy in the supermarket - the ones that have four little bottles of colour - red, blue, yellow and green. Within reason you can combine these to turn white icing into most colours. Use nothing and the icing is still white or use everything and the icing will go a black-brown colour. Use a couple of drops of red and blue and you'll get purple.

But if you start with black icing, there's nothing you can add that will make it anything but black.

It's the same with your inkjet printer - because white is obtained by not having any ink print on the white paper. But of course that only works when the paper is white. Naturally you'll get different results on all colours of paper, decreasing as the paper gets darker in colour. Print blue on yellow paper and you should get green printing.

The only way to print in white is to do what commercial printers do - use opaque inks and include a white ink in the process. And as far as I know there's no commercial ink that will do that with an inkjet printer.

I can hear lots of you muttering "Rubbish. Of course you can print light colours on dark paper." Well all I can say is, have fun experimenting, but you won't be able to do it.

About the only way to achieve the sort of result you may be after is to print the job then trim it and paste it in place. For instance, if you want to print onto a black or dark-coloured T-shirt then print onto white transfer material, trim the print to size and iron it in place.

My printer has problems printing dark colours. When printing pictures or text, it leaves horizontal lines on black only. I have a continuis ink system which has lots of black. Any ideas?


Try changing the print paper type to something other than plain paper. Use the matte paper setting, or the photo glossy. The printer will lay down more ink at these specialty settings.

Brother 420CN printer will not print black ink. Have replaced the cartridge and after several cleaning cycles, it still will not print properly. Test Print shows colors are fine but black ink is hit and...


I have a brother MFC 3240C. My Black ink stopped printing(initially printed horizontal faded lines and gradually got worse), the other colors were printing fine. I tried cleaning numerous time( 50 -100 times over 1-2 weeks ). Still no improvement. The way I print now is:
1. I go to Printer Properties
2. Change Media type from "Plain Paper" to "Inkjet Paper".
3. Change Quality to "Photo".

This takes a long time to print 1-2 minutes per page. However, this works for me since this is my Home printer and use it for printing only few pages here are there.

Good Luck

I changed the black ink cartridge and the printer


Calibrate your new blank ink cartridge, have some nozzle check, cleaning check, and printer alignment. This are procedure that new ink cartridge will have to calibrate before you use. Epson printer are very sensitive when capable of changing ink cartridge. Unlink HP directly work without any print test because the cartridge head and ink join together, Epson with ink cartridge and the head separate.
Have some test on it at Printer Maintenance.
I'm sure 100% works on it.
Good luck!

Black lines on photo


Are the lines always in the same places? If they are, then I would try using different photo paper. Humidity plays a big factor when printing with any kind of paper and buying new paper would be a good start. Make sure that the paper is made for your printer specifically. You might also try printing on plain paper to see if you get the same results.
