Hello,

Flag gears tell the printer when it is out of toner these gears are missing in most "starter cartridges". Hope you can buy this at above link.

Thank you.

HOW TO RESET THE DRUM WARNING LIGHT ON MY XEROX XC1020


Reset the Drum Cartridge NOTE: This solution should only be used if you have already replaced your Drum Cartridge and the Drum Light is still on. If you have not replaced your Drum Cartridge, refer to Related Items at the bottom of this page.
If the Drum Cartridge has already been replaced and the Drum Cartridge Light still remains lit, the Drum Cartridge needs to be reset. To view an animated guide of the Drum Cartridge Reset procedure, refer to Related Items at the bottom of this page, or follow the steps below.
  1. Turn the power off.
  2. Press the Release Button to open the top half of the copier.
  3. Remove the Toner Cartridge by pressing the green Release Button and pulling the Toner Cartridge straight out.
  4. Set the Toner Cartridge off to the side, out of the way.
  5. CAUTION: Be careful not to touch the red shiny surface of the Drum.
  6. Remove the Drum Cartridge.
  7. Face the end of the Drum Cartridge that goes into the copiers. You will see a series of gears.
  8. Hold the Drum Cartridge so that the large black gear at the end of the Drum is to your left. There will be an off-white gear above and to the right of the black gear. Below that is a set of three chocolate-colored gears across the middle. Directly below the middle chocolate-colored gear is an ivory white gear. To the immediate right of the white gear is a small black gear. This small black gear will be the gear to focus on.
  9. At the top of this gear is a Retainer Clip holding it in place, then the gear itself. At the very bottom or base of this gear is a flat black Reset Flag. Some describe this Reset Flag as looking like a flag or the blade of a hockey stick. The Reset Flag may be partially obscured by the ivory white gear.
  10. With your fingernail or a pen, rotate the Reset Flag counter clockwise so that it is next to the third or far right chocolate gear.
  11. Reinstall the Drum Cartridge.
  12. Reinstall the Toner Cartridge.
  13. Close the top half of the copier.
  14. Turn the power on.
  15. The Drum Cartridge Light should now be gone and there should be a '1' in the LED Display. If the Drum Cartridge Light is still lit, repeat all above steps.

How do I reset the counter for the drum unit on a Brother MFC 9840-CDW. It says to replace the drum but the unit is printing flawlessly.


On the TN-155 toner cartridge, a mechanical 'flag gear' that will reset the counter for each individual cartridge when first 'triggered'.
After each page print, the appropriate counters are incremented regardless of toner content (that is why it is still printing 'flawlessly') and after a pre-determined count has been reached, you will get a warning to change the drum as is will then be notionally (not actually) empty.
Before you decide to reset the 'flag gear' on the drum, make sure you are not actually nearing the physical empty state ... it might be a wiser decision to purchase a refill kit which should come with instruction on how to fill and reset the 'flag gear' (this needs some dismantling of the drum cartridge) or buy a compatible or genuine toner drum cartridge.
In any case, Google 'Brother drum flag gear' for more information.
Good luck!

Drum and Toner al-1631


If you add the toner, there is a chip on the back of the toner cartridge that has to be relplaced.
With the drum, you take off the front green cover. There is a set of gears in there. One of them has a flag like tab sticking out of a segmented gear. You have to get the gears and flag set so that the the flag is up and to the right. It will then make one swipe pass the drum replacement switch and reset the counter.

Xerox XD105F Have J2 Code, Replaced Drum and Code has not Gone away, How do I reset


On the front of the drum cartridge there is a green cover, Behind that cover is a set of gears , one with a flag like actuator on it.
Most likely the flag dropped in shipping and did not reset the drum replacement switch.
You can either try popping that cover off and resetting that foag to the up and right position or take the cartridge back for replacement.

Toner light on


Fixing this problem is very easy, even for those not so technical. All you need is a Philips Screwdriver. And it will also save you money in the process! :-)

The link above to the PDF has good images to help, so download that first.

Look at Fig. 5 on page 2. There you see 2 silver screws. Remove these.
Look at Fig. 6 and Fig 6a on page 3. Remove the cover and then remove the Flag gear (red arrow in Fig. 6) and the spring behind it as shown in Fig 6a.

Now replace the cover and the 2 screws! That's it! Yes it is that simple, just remove the Flag Gear and the Spring. The printer will keep on printing. This will also save you loads of money, as the toner can be used until really empty.

Happy Printing

Sharp 1655cs- replace the drum cartridge


There is a set of gears in the front of that drum cartridge with a flag on one of the gears, It has to be in the up position to swipe the drum replacement sensor. Most likely the flag had dropped in shipping.
You can take the green front off the drum and try and get that flag up and to the right. Or take the drum cartridge for a return and a new cartridge.
If that flag has dropped in shipping, it will not reset the drum count.

New Ink Cartridge


Is the toner cartridge an original Brother or is it remanufactured? The toner cartridge for this model is the TN-350, which has a "flag gear" on the left (gear) side. It is a little plastic piece that sticks out on the new cartridges and, after putting the cartridge in for the first time, it rotates out of the way. This is how the printer knows that the cartridge is new. Some remanufacturers either don't put the flag gear in or they forget to turn it back to the original position when they build the cartridge. So that would be the first thing I would look at.

Brother laser cartridge refills


OK.. I agree that your problem is with the flag gear. However, there is a specific location in which it needs to be situated. The purpose of the flag gear is to trip a reset actuator on the left side of the printer. The correct position of the flag gear needs to be set so the reset actuator is depressed 3/4 of the way AND where the flag gear moves out of the way once this is done. If the flag gear is moved all the way forward, you run a risk of the gear mechanism inside not rotating it out of the way...which could leave you with a 'no cartridge installed' message. When the manufacturer of the toner cartridge made this unit, they decided to put a mark on the side to, evidently, let the assembly team know where to set the flag gear. Great for us :) On the outside plastic piece that you have to remove to get to the flag gear, you will see a diagonal line and a view window. When you rotate the flag gear, you will eventually see a portion of the white gear in that view window. Line up the white gear portion with the bottom of the diagonal line (typically two gear teeth), and you're done. Assemble and run!
