I have a major problem with my 4600dn. After installing a toner cartridge it goes from full to empty in the toner supplies window in a matter of a few short weeks, even though they are hardly used. I then have to bypass the empty message in the diagnostics mode, but when I have two or more "empty cartridges" I cannot bypass at all and, thus, cannot print.
First thing u need to use a original hp supplies. a smart chip in the toner will detect the toner level. if u r using the original toner cartridge . then probem with the toner level detecting pcb

Re:
Are you using genuine HP toners? If not HP puts a chip on there cartridges that tells the machine it is a new cartridge. Some generic toners do not replace this chip therefor giving you this false message.

If your printer is displaying "Toner Empty" error message even though the toner is full, there may be several reasons for this problem.
First, you may want to check if the toner cartridge is seated properly in its slot. Sometimes, the toner cartridge may not be fully seated, causing the printer to think that the toner is empty. Try removing the toner cartridge and then reinserting it, making sure that it is well-seated.
If reseating the toner cartridge doesn't resolve the issue, the next step would be to clean the printer's toner sensor. The toner sensor detects the presence of the toner cartridge and its level, and if it's dirty, it can cause the printer to display the "Toner Empty" error message even when the cartridge is full.
To clean the toner sensor, you will need a soft, dry cloth. Open the printer's front cover and locate the toner sensor. Gently wipe it clean with the cloth, making sure not to touch any other parts of the printer.
If these steps don't work, you may need to replace the toner sensor or the printer's firmware. In that case, it's best to contact the printer's manufacturer or a certified technician for further assistance.
The toner container requires resetting.
The Brother limited warranty does not apply to any problem that is caused by the use of third party drum units, toner cartridges, or toner. ... Installing a non-Brother toner cartridge or refilling a toner cartridge will not clear a toner low or toner empty indication on the machine.
Use a Brother cartridge.
SOLVED IT! - PROBLEM: I'm using a refilled toner / NOT original Samsung (supplier: Peach, Switzerland) - SOLUTION: 1. Remove the toner 2. Simply put a tape over the four metal contacts on the backside of the toner 3. Insert the toner - It will now print, the printer says "low toner" & the LED status light is red - just ignore! It still work well.... - EXPLANATION: the chip (behind the four contacts) seems not be needed. I used a compatible 3rd party toner (Peach, Switzerland) - Observation: The refilled toner worked well for the first 2-3 weeks, then suddenly I had this error message.
Does your toner cart have any little clear plastic windows? HP printers shine a light through this window to ***** toner level. Cover one of the windows with tape & the printer will think the cart is full.
To check the toner level, there is a little clear window on each cartridge you can use for this purpose. Hold the cartridge vertically. If you see toner in the window, it is more than half full (or less than half empty, ha!). If not, slowly tilt the cartridge toward the side with the window. Essentially, how far you tilt it before you see toner determines how far below half full it is. If you pass a 45 degree angle before the toner appears in the window, it is nearing empty and must be replaced or refilled (yes, refilling is an option).
If you do have to replace or refill, don't forget to empty the waste toner bottle (responsibly, of course). By the time you run low on toner in one of your cartridges, the waste toner bottle will likely be nearing capacity.
this messages referes to the waste toner being full or not installed.
Manufactures try to stop you from emptying the container by having a small "window" that the printer looks through, when you empty the toner there will still be some toner on this window, so the printer will still believe that it is full.
a way around this is to wash the container out with water (do not use hot water as this will melt the toner). i also wouldn't recommend pouring the water & toner down the sink as this could be breaking local laws.
The waste toner is collected inside the drum cartridge. It can be emptied by removing the drum cartridge assy and opening the opaque window and emptying into a large bag. The lines on your copies are probably a symptom of the drum being worn out, so replacement is probably a better option. The drum is good for 60,000 copies.
Behind the little container for the waste toner there is a sensor that senses whether the toner basket is full or not. If the sensor itself is dirty, it can give a false reading. First try cleaning out the area under the container to see if the switch works. Also make sure the container is clean, because the sensor works by sight, so if it looks full because it's dirty, it will give a false reading. I have heard of people disabling that sensor in various ways, but that can get dangerous to the printer. I can't recall the details on that exact model, but I believe there is a diagnostic of some sort that can test that sensor to make sure it works right to begin with.
