how do you check the different components of ink? like forensic stuff???

It's easy. Spot ink onto a tissue paper. Dip one end of the tissue paper in a pan with any alcohol. Let the alcohol travel along the paper and make sure it passes through the ink spot. Some components of ink which are attracted (more soluble) to alcohol will be carried with the solvent but will eventually settle somewhere else in the paper. Let the alcohol evaporate and you can see the ink components, more or else, separated. A more scientific way of doing the analysis is by chromatography: thin layer chromatography (TLC) or gas chromatography (GC). Check the web.

Assume you have checked your print cartridges? If three colors in the one cartridge you need maybe to replace it as the yellow and red are all gone?

Below are the steps to check the Ink level on a HP C5180 All in One printer:\n\n1) Press Setup. \n2) Press  to select Tools, then press OK. \n3) Select Display Ink Gauge and press OK. The ink levels are displayed. (The ink volume shown is approximate)\n\nIf an icon is empty, the corresponding cartridge may need to be replaced soon.

online.. thru your comp.. start the "Status Monitor" ..\n.. it sits someplace in "Start" (if on Windows)\n\nOr simply go to the printer name in "Printers" folder & right click-> go to properties- then all thse tabs come up for "Head cleaning" "Nozzle Check" etc...\n\nThere.. a tab has status monitor...\n\nHowever, thru experience using my old Epson Stylus 1200\nI have come to know that its a bit waste as the Nozzle Check & Head Cleaning both deplete the bloody ink resorviors..\n\nI now, manually take them out \n[HIGHLY AVIODABLE AND WOULD NOT RECOMMEND THOU]\nto get a feeling as to how much is there which I can get since so many years..\nGive it a good shake & I put 'em back...\n\nThough unlike HP, Epson cartridge head doesn't get replaced each time, so its a big headache to try remove cartridge\n(one risks damaging internals as ink might pour out of gaping hole in cartridge- there is a certain trick jerky movement to get it out)\n\nPlus, lastly, the damn things sort of dry out even if printer left unused for under a month & so software may still detect a semi full thing as, one needing replacement

by hand and make sure u dont touch the signature or it will come off depending on what kind of ink it is.

Maybe list who makes it, the serial number and date stampings, maybe you'll get an answer.

Well well i am sorry to inform you that i have asked this question before and tried all the answers -and i have pulled the right hand side panell off and totaly swabbed out the waste ink tank which is under thecartridge carrier at the extreme right hand side,,where it does its mixing.and its hardly a tank at all,its a tiny little tray with a bit of foam to absorb the ink.i used a sray on alcohol solution and cleaned it thoroughly,but the darn thing still kept saying waste ink near full?i threw it in the bin about an hour ago,as i rang cannon and the cost just to look at it was greater than a new one.I did get a bit longer out of it by reset button-but not longat all.I have just loaded an epson stylus cx3700 its better than my cannon imagecass mpc190 was and cost me 79 dollars here in australia.--check my q&a if you  want to see my results but i am afraid its hopeless.

Ink screening is commonly used for this.

You can either look it up or determine it experimentally.\nI cant get much more specific without additional details.

The blue and yellow ink might have been finished.So, only pink(no other option for the printer) color is being used instead of all colors.Get a new Ink Catridge.\n\nCoz all the colors are made from 3 basic colors..so basically there are three basic color outlets in an Ink catridge of a colored printer.\nThus if two most used colors get exhausted, you get everything in the third one.

nah in the bottom corner of your screen...there should be a little printer icon next to the time...double click it if you have windows...and it should show the ink levels

Look for any of these marks:\n\nSilver- Ster, Sterling, 800, 900, 925\n\nGold- 585, 9K, 10K, 12K, 14K, ect.\n\nIf they are unmarked:\n\nDo not acid test, especially silver! Take them to a Jeweler. Most of the time, they will tell you for free.
