Question about Canon Office Equipment & Supplies

1 Answer

When we print black type on a white background, the background comes out gray and gets rapidly worse from one sheet to another. Although we have calibrated and done all of the other maintenance and cleaning that we know of, it is still happening. We think either the fuser, black drum or belt needs to be replaced. Do you know which one it is? Also, is there anything we need to know about replacing whichever part it is?

Wont print in full black, does print in grey or any other colour.


Assuming you are using MS Excel, try going into page setup, sheet, and check the setting for 'print black & white'. If it is checked, then try unchecking it.

I have one problem with hp laserjet P4014n printing all paper black. the background is black all but word are showing can someone help me in this


If your background is "Black" it's going to print it all black, change your background color to "Gray" and your machine will then print a gray background instead of black. Also note that when you print a black background your toner life expectancy will be no where your expected yield ratio is. Average yield is 5% for X (X meaning size of cartridge) amount of printed pages. If your printing a black background your utilizing 100% yield coverage. Not sure if this is the answer your looking for. However basic black and white printing with a black background will print the page completely black.

Hello, I would like my pictures to have a white background. When I take the picture on a white background the background ends up looking gray. I am taking pictures of baby clothing and I want the clothing...


Exposure meters are designed on the premise that the scene is an average, middle gray, in brightness. If you take a picture of a white dog playing in the snow, the camera will try to make the picture come out middle gray (a gray dog playing in gray snow). If you take a picture of a black cat sitting on black asphalt, the camera will try to make the picture come out middle gray (a gray cat sitting on gray ground).

If the white background is dominating the scene, the camera will reduce exposure to try to make the entire scene come out middle gray. The solution is to meter on something else. Move in close and fill the frame with the subject, press the AE-LOCK button, then move back, compose the picture, and take the shot. For full details, refer to the "Shooting with the exposure locked --- AE-LOCK" section in the manual (page 52 in my copy).

If you're taking a lot of pictures, you might want to switch to Manual mode and set the exposure accordingly.

Using Canon iP4600, I'm trying to print a black-and-white photo with a black background and a half-tone image in the front, but I keep getting purplish and black stripes instead of an all black background....


Hi there

Sometimes, printers use colors from the other cartridges in order to form a deep black colour. It does seem that not enough pure black ink is getting onto the paper.

Can you check that there is enough black ink remaining? If so, go to the print options of the program from which you are trying to printer the image, and set the colour output to black or greyscale only. This may be within an option called Printer Preferences from the Print dialogue window of the program from which you are printing from.

Then, print an image as a test and see if it comes out in black only this time.

I look forward to your reply.

Regards

Want a B&W copy from colored sheet of paper w/o dark background.


It's never going to be perfect (unless the background is quite light in colour), because the copier basically "sees" the coloured background as "gray", and the darker the background the more "gray" it looks. Try setting the original type to "photo" mode, and then adjusting the exposure a little lighter/darker....that's all you can basically do.

Gray backround


Does your scanner software give the option to choose different modes...grayscale, color, black & white?? This sounds like it's scanning in grayscale....if you can change it to black & white, the background should remain white.
