I have used about half of the toner hp Q6000A(yellow) of hp 2600 and now it asks to replace the cartridge. So I want to know if anyone helps me by showing any procedure to reset these chips.So i can use the full quantity of toner.

It is my understanding that these chips are not resetable in any conventional manner. there are some companies that can re-flash those chips. My guess is that you have used all of the toner in the supply hopper and have toner in the waiste hopper which makes the cartridge feel like it still is half full. If you run color toners past their effective life you take a chance at blowing a bushing and getting a major toner dump in the machine. It would be best if you just replaced the cartridge.

These cartridges countdown even if you don't print with the particular color. If you print lots of pages that are only black, the color cartridges "count-down" too. HP is really screwing us all.

Maybe they are but you really need to know how they produce color and black and white pages before making judgments. When you print in black and white hp uses the color cartridges along with the black to produce the pages so even if not printing with colors you are still using the color cartridges. Some of their models, but not the 2600 allow you to turn off using the color toners.

The 2605dn counts individually on the chips. It does not count "pages printed", it counts a fraction of color pixels. The issue is that each full toner cartridge would print around 2500 pages covered with 1/20 (5%) of its toner, or ONLY 200 pages of 100% covered with its color. If you print a whole page with magenta for example, it will only print 200 pages. So, counting pages printed does not work. A whole page may contain around 8 million pixels, the machine counts 1/1000 of it, so a 5% covered page represents a count of 396, times 2500 pages, it reaches the count of 1,000,000 when the chip will overflow and say the cartridge has no more toner.
IF all the colors would count no matter what color you used, then ALL colors indicator would ALWAYS show the same level, right? and it is not the truth, you can see different levels for each color.

Chips can be blocked allowing for maximum yield of all 4 cartridges.Blocking chips will render useless all toner management functions and User realizes exhaustion when quality of print decays.
To block chips press green button for main Menu Menu •Right arrow to System Configuration, confirm with green button •Right arrow to Print Quality, confirm with green button •Right arrow to Substitute Suplies, confirm with green button •Right arrow to Ignore empty and confirm with green button
Printer gets back to ready.

I turned off the toner sensor, and got about an extra six month's of printing out of my color toner cartridges. I replaced them when they were almost empty (showing 0% remaining) and the print quality started to degrade beyond what I find acceptable. A little gray background started after about three months, and red streaks began after about six months.

When I go tpo "System Configuration"; then to "Print Quality"; I then get a choice of "Replace Supplies" and then "Overide Out", not Substitute Supplies and Ignore empty.
I have model 2605DN and all my color cartridges get a page counted even if the page is all black. I have opened case 3601338360 with HP. Sandra responded and told me via e-mail: with model 2605DN there is no way to disable color counts". Is she correct?
HP will tell you there is no way to reset the counter, but they won't tell you about turning off the toner sensor. I have run experiments with the sensor on:
My findings are: Every page printed is counted on all four cartridges. I print a lot of only black and all 4 toner cartridges show the same count.
Turning off the sensors saves me a lot of money and I only plan to replace toner when the printing shows I need to. I have three other laser printers, with two others being HP monochrome and they don't count pages, so I replace them only after I have removed the cartridge and shook it side to side and the problem doesn't go away after only a few more printed pages.
I know of no damage to the printer that can be caused by an empty toner cartridge, and I know if I printed full pages of black, the toner would run out before the page count hit 2,000.
If this would cause the printer to fail, HP would have a fix out very quickly, because that would be a flaw in the design of the printer.
However, if the sensors weren't there at all and the printer is being used on a network with many users, there would be a lot of wasted paper when the cartridges run out one by one. So the fix is to count all pages on all cartridges equally.
But I don't use my color laser on a network, so I can easily see when a color is missing and replace the toner to shake it first, because there will be areas missing and not on the whole page.

The only thing with the toner override is that you need to watch the print quality towards the end. Ive refilled the hp 1600 twice now and its working fine. You also shouldnt mix any toner i.e. old and new toner.
To block chips press green button for main Menu Menu �Right arrow to System Configuration, confirm with green button �Right arrow to Print Quality, confirm with green button �Right arrow to Substitute Suplies, confirm with green button �Right arrow to Ignore empty and confirm with green button
It is not a matter of there being a flaw in the printer itself. The cartridges are DESIGNED to fail. If you run them past the designed life the bushings can fail, the wiper blade can fail, or the waste hopper can overflow. Any of these can cause toner to be dumped in the machine which will eventually cause the printer to fail; however, you may override the sensors as you wish. The original question was how do you reset the chip. The chip can not be reset in any conventional way. There are manufacturers that can re-write the chip or sell you a replacement to accurately track the usage if you want.

Disabled my HP Color Laserjet 2605DN's chip's sensor [Main Menu -> System Setup -> Print Quality -> Replace Supplies -> Override out (from Stop at out)]. I mostly print mono (with all but the neutral greys setting to use black only), so it counting colour pages like that (equally) was seriously annoying and stupid (from a non-business/user's point of view). Been working great for a while now, not sure what on Earth HP/Sandra was saying to you, I suggest you (Anonymous) just give it a try. Thanks all :-).
