 | Resetting of chip for hp toner Q6000A by jk_nvs@yahoo.co.in (5/24/07 1:47 AM) reply | + / - | 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.

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.

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.

| Re: Resetting of chip for hp toner Q6000A by pilrengaw (1/28/08 12:49 PM) reply | + / - | 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.

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 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.

I am really upset when the page count and the % used goes up on each color cartridge equally for each page printed, even if page is all black.
I opened case 3601338360 and was told by "sandra_spilde" that "there is no way to disable the color counts on model 2605DN".

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?

| Re: Resetting of chip for hp toner Q6000A by George Brandt (7/24/08 7:42 AM) reply | + / - | 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.

Ive refilled the hp 1600 twice now and its working fine. You also shouldnt mix any toner i.e. old and new toner.

| Re: Resetting of chip for hp toner Q6000A by partsguy (8/1/08 10:44 AM) reply | + / - | 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.

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 :-).

 | Re: Resetting of chip for hp toner Q6000A by jerrisn (11/12/08 12:26 PM) reply | + / - | I just did this with an HP LaserJet 4700. It's called supply OVERRIDE with this model. Here is what the printer informs me when I enable it:
Supply Used After Out with OVERRIDE
*(See Warranty Note)
*Warranty Note
Using OVERRIDE may result in unsatisfactory print quality and unavailability of certain features.

OK, if you tell the printer to ignore the toner sensor and take the cartridges to the point of actually being empty, and only then do you replace the cartridges with *new* ones, I can assure you that the bushings, wiper blade and other parts will not fail. That is just plain silly and something that HP and its partners who resale new cartridges want the public in general to think.
Now, if you use re-charged or re-manufactured cartridges and that company that handles the removal and adding of new toner do not also replace those parts that will wear out, then yes, you may end up on the receiving end of having a bad thing happen to one or more of your cartridges. That's why you want to use reputable re-manufacturers with some sort of warranty if you go the re-manufacturer route and you don't just want to remove any remaining toner and simply refill with replacement toner for more than one or two times-then things like bushings and other components may in fact fail-or just disable the sensor and simply use the cartridge until empty then buy a new one-I have no problems when this is done.

| Re: Resetting of chip for hp toner Q6000A by Carolin (4/1/09 5:01 PM) reply | + / - | The 'Cartridge out override' process is explained in the printers User Guide.
If you don't have a copy then download the User Guide as a pdf from the hp website: http://welcome.hp.com/country/us/en/support.html
Go to page 134 'Cartridge out override' in the maintenance section.
You will find a step-by-step how-to as mentioned by other folks earlier. It also talks about warnings and why the printer is not set to 'Cartridge out override' when you buy it.

| Re: Resetting of chip for hp toner Q6000A by Anonymous (4/8/09 9:30 AM) reply | + / - | The HP Color LaserJet 2600n printer displays an Order supplies message when a cartridge is running low and a Replace supplies message when a cartridge has been depleted. To ensure optimal print quality, HP recommends replacing a cartridge when the Replace supplies message is displayed. Replacing the cartridge at this point can help prevent waste of media or other cartridges when one cartridge produces poor print quality.
The Cartridge Out Override feature allows the printer to continue using a cartridge that has reached the recommended replacement point.
WARNING! Using Override may result in unsatisfactory print quality and unavailability of certain features (such as toner remaining information).
WARNING! All print defects or supply failures incurred when an HP supply is used in Override will not be considered defects in materials or workmanship in the supply under HP's Print Cartridge Limited Warranty Statement.
Configuration
Cartridge Out Override can only be enabled from the printer's control panel menu.
1. From the main menu, press (RIGHT ARROW) to System setup and press Check Mark button (SELECT).
2. Press (RIGHT ARROW) to Print quality and press the Check Mark button (SELECT).
3. Press (RIGHT ARROW) to Replace supplies and press Check Mark button (SELECT).
4. Press (RIGHT ARROW) to Override out and press Check Mark button (SELECT).
5. Press (Check Mark button SELECT).
If Stop at out is selected, the printer will stop printing when a cartridge reaches the recommended replacement point. If Override out is selected, the printer will continue printing when a cartridge reaches the recommended replacement point. The factory default setting is Stop at out.
On-going operation
Override can be enabled or disabled at any time, and does not have to be re-enabled for each cartridge. The printer will automatically continue printing when a cartridge reaches recommended replacement. The printer will display a message Replace supply Override in use while a cartridge is used in Override mode. When the cartridge is replaced with a new supply, Override will de-activate until another cartridge reaches recommended replacement.
