How to use black ink instead of color, for black print
Do I understand the quoted text below correctly:
Does Brother make me change the preference every time I switch from a color to a black&white original, and vice versa, if I want it to use only black ink for black? Do all printer makes work like this? If it can tell which color ink to use, I figured the printer software could tell the original was all black and then use nothing but black ink. Is that too much to ask? http://support.brother.com/g/b/faqen...aq00000038_008 For my all-in-one inkject printer, Brother says: "Another factor that could be affecting your color ink consumption is the amount of printing from a computer, even if the print jobs are black only. Because this machine offers full color printing, the default setting in the print driver is COLOR. This means the machine will automatically mix ALL the colors to produce a selected color, even black. "If you would like to print from the computer using the black ink only, you need to change the printing preferences to GRAY SCALE, and also select "Plain Paper" at Media Type." I don't mind setting it say I'm using plain paper -- even though I thought I should buy inkject paper instead? -- but I know I will forget to change the driver from gray scale to color every time I preint color, and back again every other time. If it can tell which color ink to use, I figured it could tell the original was all black and then use nothing but black ink. Is that too much to ask? I have it set for color but I've been printing black and white crossword puzzles. I can't see a trace of any color but black. How can that be? Does it mix the 3 inks before it sprays it on; does it have perfect spray location so that there is no penumbra of a color; or is it really using black ink despite what the FAQ says. I know the ink level monitor is not that precise, but I've only printed a few pages, all black, and so far I haven't seen either a black or a color ink level go down. If you select other Media Type than "Plain Paper", color inks are used. In detail, please refer to the Related FAQ which is located in the end of this page: "When selecting grayscale printing in the printer driver,does this use only the black ink or all the ink cartridges to produce the grayscale image?" Here is the "related FAQ": "When selecting grayscale printing in the printer driver, does this use only the black ink or all the ink cartridges to produce the grayscale image?

There are exceptions to this but I am sure that the FAQ is correct. Some other manufacturers do similar things. Fear not the ink levels will go down. Tony |

They are of course the same one, but one has the default set for monochrome and one for colour. Then you just print to the appropriate one. I have done this, but my printers are networked. I'm not sure how easy it is to share a printer 'port' if the printer is otherwise connected, but it's worth a look. |

Yes and no. Answered in the FAQ for you. Note that there is the issue of which black you are talking about. From the context it is clear that you are talking about pigment black, and not photo black (I hope I chose the right words here, I am more used to the Japanese terms these days). Do all printer makes work like this? Most inkjets work like this, yes. I think you have started to read the manual more deeply, so you can see how different media affect the possible selections. You should remember this as part of your "situational awareness". If you select other Media Type than "Plain Paper", color inks are used. In detail, please refer to the Related FAQ which is located in the end of this page: "When selecting grayscale printing in the printer driver,does this use only the black ink or all the ink cartridges to produce the grayscale image?"

Only plain non-photo media use black ink, i.e. plain paper, envelopes, postcards (obviously not inkjet postcards which is a photo media). 2. So if you select one of the above, you can switch off colour inks entirely by selecting black. On the other hand, if you have different media selected, then choosing black will have no effect whatsoever. Black will never be used with photo media unless it is photo black. 3. Non-plain media (usually photo media) will never use pigment black, only photo black. So on printers without photo black, photo media use only cyan, magenta, yellow (if there are other colors then photo black will generall be the first among them, followed by photo cyan, photo magenta, and even photo yellow, gray and other colours for high-end printers). 4. If you are changing between media to a photo media, you will encounter incompatibilities in the settings, so the driver will still use color even though you have selected black only. Sure you can print in grayscale, but the grey will be made up of cyan, magenta, yellow. Hope this is clear. -- NNTP on Emacs 24.3 from Windows 7 |

Shame that it's so difficult to tell what rules a given printer uses. The moral is always to have a supply of all the coloured cartridges available, even if you only want to print a letter in black text :-( Even if a combination of colours plus black gives a blacker black, IMHO it should always be possible for a printer to work in limp-home mode using black only. That's what I'd require all printer manufacturers to do if I was God :-) |

That's what I'd require all printer manufacturers to do if I was God :-) The only way to know for a particular prinjter really is from the manual, so it should be explained there. Usually for plain media lower quality will be able to use K only, higher quality probably not. If you select black-only cartridge, possibly only lower-quality printing will become available in the driver settings. Analysing printjobs can help to some degree. For example, in the gutenprint project (linux/MacOSX mostly inkjet printer drivers) I analyse Canon printer printjobs which contain colour information for each pixel (not the actual printhead colours, since the firmware on Canon printers does that final translation). From experience, if the metadata only contains K (black) then it is almost (no exceptions found so far) certain that the printer will use black only in the actual print. -- NNTP on Emacs 24.3 from Windows 7 |

This is to protect the head regardless of what the cynical amongst us might think. Depending on whether the fixed printhead is piezo or heat driven the ink is needed to either lubricate or cool the head, in both cases absence of ink damages the head. For printers that use cartridges that have built in heads, so that the head is replaced when the cartridge is replaced, it is a matter of design whether the printer will work with some ink missing and that design may be to allow enhanced black printing or (rarely) to force people to buy more ink they do not yet need! There is plenty of criticism of printer manufacturers for various reasons - this reason is more imaginary than real. To allow limp ho,e would need a brand new design for printheads, as yet not seen.

Interesting. I hadn't realised that there was a technical reason for it, as opposed to a sales one. Come to think of it, my HP which would carry on printing had the head in the cartridge whereas the Epson which won't has a head that is not replaced when the cartridges are replaced. Shame that if you select black-only, power to the colour head isn't disabled so as to remove the need to lubricate/cool it. |

The ink is squirted from the printhead when that colour is activated, so AFAIK the only time a printhead warms up is when it's being used. Exactly my point. So if the print head isn't used (eg by turning it off or by making sure there is no signal to send ink to the nozzles of any of the colours) those nozzles won't warm up and therefore they won't need ink to cool/lubricate them. Therefore you can continue printing in black without the need for all the coloured inks to be present. Since you and I seem to be saying the same thing, I'm not sure why you are mystified by my statement. |
