All paper is black - Toshiba 2860 Copier

"Photo black" is designed specifically for glossy photo paper. Matte black is for non-glossy paper, including plain paper. Matte black will print darker on non-glossy paper than photo black does.

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.

hi,
ur machines paper sensing sensor have some problem. did u used the paper with black mark on the side.
remove the paper cover . u can see a black square sensor near the side of thermal printer. clean the sensor with an ear bud. do not use any solutions. then check again.
remember use good quality paper. if the black mark on the side of the paper is not perfect this problem can occur (black mark on the paper is for page count and paper sensing)
ok

hi,
use only paper for schiller AT1 . also check the paper sensor. slide the paper cover then look at is printer head side , u can see a small black square portion in the side . clan it with an ear bud. do not use any solution. after cleaning put the paper back and test again. use paper with black spot on the side. machine counts the black spot.

Try this:

The HP all-in-one product will print black copies using both the color and black cartridges to create composite black in Normal and Best modes. This is necessary to create the correct grayscale shades.

1. The color cartridge may be out of one color of ink. Perform the steps in the 'Colors are not correct' section above to verify that the ink cartridges are not low on ink.
2. Verify that the correct paper type is selected in the Paper Type setting.
3. Some photo paper has different chemical characteristics than Hewlett-Packard paper. The HP all-in-one is designed for use with HP Premium and Premium Plus Photo Paper. The photo paper, paper-type setting should be used with HP Photo Paper. For other paper brands, it may be necessary to use the plain paper or premium Inkjet paper, paper-type settings.

OR: The ink cartage you have may be defective if is a refilled or recharged cartage.

Try removing all ink bins except black then you won't have any problems. You should also be able to go into your printer settings and select "Black and White" or "No Color" and it will print ok. Removing the ink trays is the easiest way though.

The feed roller was turning but the paper wasn't moving and so I kept getting an "out of paper message." The paper was actually getting caught on a small black piece in the back of the printer. I removed the black piece and the paper start to feed fine.


Remove the back access door (it just pops out... no screwdriver required). The black guide piece (2nd from left) is about the size of my little toe after I took it out. Use a flat head screw driver to pop it out... that should leave 3 black guide pieces left. Put the access door back on the printer and the problem should be solved.

Few questions, are you running true Canon Inks and refills are always a off black not a true canon black!

Have you tried doing nozzel check, does the top black squares all come out ok? if so it could be down to the paper and the inks!
if you use 80gsm paper does it print ok?

Hope this helps

Thats because it's using the other colours to mix what it thinks to be shades of grey. Due to the black ink being pigment based and the colours inks dye base, when printing onto glossy paper the machine will use the colour dye based inks to make up black. 
If you were to print on plain paper, set to greyscale, then the machine will just use the black as the pigment ink sits onto of the plain paper and will not run should the paper get wet.  With glossy paper the ink has to be absorbed into the paper ad the Black pigment ink will not do this so the machine will use the coloured inks.

Sucks but true.
