After running SP2801 on this Ricoh 3035 I am working on, I noticed that the number setting is lower than what I am accustomed to seeing on this particular machine. This problem occurs whether I am using old or new developer. If I put the numbers back to its initial settings and watch the toner cartridge, it turns a couple times. However, when I start to makes copies they gradually go lighter and lighter but no add toner message is shown on the display and no SP error code comes up. Is this a TD sensor problem? Also the machine has been cleaned thoroughly and has new developer. Thank you for any help provided.

Re: Copier asking for toner and not needing it
Try force toner then if still light copy you have to check the mylars on the toner hopper.Nobody is perfect.. -
Re: Copier asking for toner and not needing it
Check SP2-209 is set to 60 (normal)
(higher # = less toner)Comment

Re: Copier asking for toner and not needing it
rsyarcia has a point, the 35/45 cpm machines occasionally have problems with the mylars falling off in the toner bottle holder unit, causing prints to become light without any add toner message or activity by the machine, even if the developer. drum and charge roller are replaced.
If I find the mylars have fallen off, and I can fish at least two or three of the mylars out of the toner in the toner bottle holder, I re-install them with screws. I just line the mylars up as if they were correctly installed, bore a small hole completely through the mylar and the plastic surface it was mounted on with a jeweler's screwdriver, then fix them in place with the extra screws left over from replacing the PCUs in a LD435/LD445 (MP C3500/MP C4500). I've never had that problem reoccur after doing that.Comment

OR just replace the toner supply unit....fairly cheapComment

Re: Copier asking for toner and not needing it
besides the hopper issues. one other issue i had rarely on these machines is the developer unit, if you take out the dev unit on the front of it there is a black cover that covers 3 gears that drive the developer paddle, i have had this cover fill with toner before making it hard for the gears to turn so toner is not churning through the dev unit very well. i would double check the gears and clean them, also clean the mag roller with a brass brush. i would also clean the id sensor in the machine.
beyond some methods i wont recommend thats all i can think of for now, i would definatly check the hopper out the mylar issue noted happens a lot, it could be that only a couple of them are broke so its getting some toner just not enough.Comment

Re: Copier asking for toner and not needing it
More than likely tis the mylars in the hopper. Normally, I just replace the snap in part of the hopper. Takes up less room in carstock. I agree with all the posts on this subject. They are all valid fixes. Another fix, although rare, is SP2-201 (bias) should be 540V. I say this because some techs know that changing bias is a quick fix to get them out the door on Friday afternoon. Let us know what you find.Comment

Re: Copier asking for toner and not needing it
Had that problem today on a MP4000 - turns out the problem was on the tonner hopper but on the small spring-loaded gate-thingy on the right of the tonner hopper. After fiddling with it, in the end I just removed it and the copies turned solid black again and so far no "add toner" message. I'm still not sure what that part is supposed to do, but in this case removing it solved it. I still have it in my pocket in case I need to put it back, though...
EDIT: I'm talking about the small plastic with mylar inside the red cover.

Re: Copier asking for toner and not needing it
if the solutions above doesn't work then try checking also the toner hopper motor.Comment

Re: Copier asking for toner and not needing it
Seems we are all familiar to the "add toner" issues on 35's.
I first check the drive...cheat front cower,remove toner holder and bottle,pull up your sleave and put your fingers on drive...to see if it's revolving propper and is it strong enough.
If drive is ok then look the holder...does it open the toner bottle (probably not problem in your case),if necesery dissasemble and check the paddles that's pushing toner out in PCU toner pathway,front cower is usualy cowered with toner if there's a problem with transfering toner to developing assembly via PCU toner pathway.
Vacume PCU pathway from both sides (I dissasembled that only once and not bcs of toner ishues but it had drum bearing screw inside?!?!?!)
As Counsel mentioned the housing of gears driving the mylars in developing assembly can be cloged with toner slowing them down up to point that it starts making noice...like someone is beating machine with baton noice...
In your case I'd allso check connection of TD sensor to the back of developing assembly,sometimes female connector may be broken if developing assembly is pushed in harder...
And are you using Ricoh toner or some "for use thingie"?
Mrwho that thing you removed probably didn't sit well on drum unit...it runs in to drum unit casing and opens toner holder.u may have something disloged on machine.Gears,springs,clutches,sliders,connectors and electronics...who on earth can tell what's wrong with it?Comment

Re: Copier asking for toner and not needing it
Besides cleaning it out at pm's, i suspect 1 of 2 things is happening either toner is getting in at the seam of the plastic cover since this model tends to run dirty, OR when you remove the gears in there you can see there is a developer seal on the shaft and it could be that those get worn and seap. I know on the 5500's with the big dev casing the rear seal leaks and messes up the gears on the feed units so its possible the seal just wear out and little by little toner gets in there.
I would just make sure anytime you take out the dev unit to just pop off the cover and vacum it, or if you have a machine that seems to always be full try replacing the seals and see if that helps.
I also think I know what MRWho is describing and i have had that happen as well, good call.Comment
