Actually if you are using that much toner the problem should be in the developer calibration. Did you change the developer also?

Yup, I agree with Mysticus. However, could be a bad toner cart. But, have heard from a couple techs. that do have to rep. both Drum and Developer as a pair on this model. Partly because they get to stuck together, and the image quality goes to hell after about 100K pages. You can always attempt to rebuild the Developer by rep. the Cylinder, Rings, Seals, and such. But then again, you could also rebuild the transmission on your 1986 Chevy Chevette if you are a fan of lost causes. Good luck sir.

Don't you wonder where the toner is going? Can you see where it is leaking anywhere inside the unit? Do you have your service manual? Are you using a compatible toner? Have you checked your fuser unit to see if it is caked with excess toner? Was your drum all black with toner? How did you copies look?
I don't care much for Canons personally. Too much troubles but will work on them if the pay is good enough.
Without looking at the unit it would really be hard to tell but the above questions should get you going. If all else fails call a canon tech or call one of the techs at Precision Roller they should be able to put you on the right path. There are several possible things that could be the problem and you have not provided enough info for any good tech advice....Good Luck !!

Hi all,

you said !!!Developer!!! but like i know Canon series doesn't work with Developer....aren't like Minolta or Ricoh....
My Canon ir1600 maybe can't detecte toner ...it gives me a bad copy, after that it anounces "it needs toner"....i bought a new cartridge for canon ir1600(original)...the same problem...
What can i do if it can't detecte Toner....???

Thanks for your help You All...Nassim

wait a minute- I think we're a lil confused. Developer in this model, is the actual Assy. that the Toner Cart dumps into to (Gravity fed), no the typical Developer/Carrier Material that is common in other copiers. The Toner Detection (only one in this model) is in the Developer Assy. If you just put a new Drum in- try reseatting the drum. After that, reseat the Developer Assy., which consists of removing the drum first. Becareful, the Developer Assy. is a little tricky to reseat, because it is on an angle. Also, make sure that the toward the front right of the Delvelop Assy., that the metal shaft with gear on it is touching the electrode. This will cause a no cart. condition also. Also simple make sure that the you are turing the toner cart handle also (I know this sounds stupid, and the front door should not shut if the toner cart is not in correct position, but you would be surprised what breaks/or is missing from these machines that cause weird issues.) If all this fails, you would be looking at a Developer Assy., p/n: FG6-8413-000 and beyond that something logical like a DC Controller. What is the actual message on the display is it

"Toner Empty/Replace Cartridge" or is it

Hi,

it shows on the screen 1st "Mixing Toner" for 3 minutes....then all looks good...when i made a copy... 2nd it shows me this ---> "TONER EMPTY REPLACE TONER".....but cartridge isn't empty!!!

[CanonHPTech]

Sounding more and more like developer, sir. That's the only place where there is a toner sensor in this unit. There is no toner hopper assy. I imagine that you could vacuum out the developer and attempt to check/repair the sensor, but I wouldn't bother. More than likely its Piezo and won't be repairable, and I did not see it in the parts lookup for this assy. Really not much available outside the Cyclinder, spacers and entire assy. Good luck.

Hi,

I'll change it I don't have choise....Thanks for all...cordially Nassim..

Hi sir, can i ask if you have remove the developer?
i was servicing this machine for a long time now but never experience this problem, the waste toner container on the drum unit is very small and to make the life longer a regular service is needed, the drum life is 20 thousand it can go more with a regular service, maybe you put back the developer in a wrong position that is why the machine does not detect the toner. check it and try to correct the position, its tricky.

hi all
themessage mixing toner and then replace toner , there is leaf spring which give the tner tank bias may be it is not in its position or dirty plz check it ,i saw this problem before and this is the solution.
thanks

If you are sure, the Toner Antenna in the developer Unit has good contact, you can try to adjust VR402 and VR403 on the DC Controller bord, they are responsible for the Toner Level measuring. Just make sure, that you are able to remember their actually adjustment position, before you begin to fiddle around

BTW.: Did you open the Development Assy to assure, that here is really enough toner in it?

Yup, I agree with last tech about checking that bias contact... stated it in a previous post to this thread, see here:

"If you just put a new Drum in- try reseatting the drum. After that, reseat the Developer Assy., which consists of removing the drum first. Becareful, the Developer Assy. is a little tricky to reseat, because it is on an angle. Also, make sure that the toward the front right of the Delvelop Assy., that the metal shaft with gear on it is touching the electrode. This will cause a no cart. condition also. "

I really don't want you to buy a Developer Assy. unless you have to. Sir, please let us know how you made out.

[Herrmann]

May i place a correction here:
The metal shaft is the connection to the developer BIAS not to the toner antenna, this contact lies behind the metal shaft.
