Sharp AR M350N toner problem. two new toners and still says "check the toner cartridg

[tonerjockey]

customer called last week and needed new toner. i sent a compatible from reputable source. customer said same thing. i went out and everything looked good. i resent another compatible and again, same thing. i went back out and the display said "check the toner cartridge. (code: F2-02). but after trying to reset it, it went to the "check toner cartridge". Hytec told me that if the control board is bad, it wont recognize the CRUM chip on toner and kills the crum chip. that i would need to replace the PCB board and a new toner.
i removed the toner motor behind the board and tried to see if it would turn, but apparently after its asking for toner it wont attempt to tone up. even after a sim. 14 and also a sim 16 clear, it boots up into the check toner. never tries to load toner. i forgot about the sim. 10 toner feed, so i will have to go back.

my question, i was wondering if this box is like the Lanier 445C (Ricoh aficio MP C4500), in that if it has several toner feed failures in a row, it will kill the CRUM chip. so after replacing the toner pump on that one, i also had to install yet another toner. if the Sharp toner motor was bad, would it do the same thing??? if so, is there a source for a new CRUM chip?
any help would be greatly appreciated. have a great weekend, Jim

Have you checked to see that the gears turn on the toner cartridges? I've had ten calls of a similar nature when using non OEM toner this summer. Also remove toner motor and execute sim 10 to check if motor engages. Recently had a motor fry from clumped toner jamming it up. I've never had a sharp kill the crumb chip before. Be sure that toner pipes are clear, and clean machine contacts with electro-contact cleaner. Good luck

thank you Nottoosharp. i will go back and do the sim 10. wish i had remembered yesterday. i really appreciate your input. Hytech always points to a board, even when its likely not. they still win, i still loose. have a great weekend.

I've had machines that as they aged refused to except non-OEM toner

really? ok, im already in this for 2 toners, going on 3 trips, and whats weard, if the chip is still good, why wont it try to tone up. just constantly shows the check toner cartridge. and p. roller has no stock on the motor. i have another source, but its days away by UPS.

I've been trying to figure that exact same thing out for quite a while. Perhaps if you have a partial OEM toner that will fit the machine give it a shot and if you have access to another machine try putting one of the "bad toners" and that and see what happens

great idea. but my only other AR M350 is 14 miles away towards downtown. and i have learned, dont mess with a good machine from a different customer. i am going back there now to run a sim 10. let you know the outcome. i also found the CRUM chips on amazon, so i could possibly make a good one with that?

I don't know, but please let me know the outcome.

I have had bad toner clog up the shutter on the DV unit. The toner kept trying to dump on top of the shutter and backed up into the cartrage. The only way to fix it was to take the DV shutter apart, clean it and replace the bad toner.

Re: Sharp AR M350N toner problem. two new toners and still says "check the toner cart

seems like i had a seized dv unit do this, just a thought.

Re: Sharp AR M350N toner problem. two new toners and still says "check the toner cart

ok, sim 10 makes the motor turn strong. i ran sin 25-01 and dev unit turns ok. i checked the shutter and it seems fine. the drum did have a black dusting, and in years past with say, a sharp ?SF 8600 if the erase lamp went bad, the machine would keep warming/ toning up till the hopper was empty and call for toner. so i pulled the charge, but as i said, without a new CRUM, it wont do anything any darn how. so, i told customer it needs a new control board and an OEM toner. i made the mistake yesterday of telling her i may be able to get a CRUM so the full toners could be used. so, she don't want to buy any more toners. so, if they approve the board, i hope that the replacement crum's i found on amazon will actually work. i still may tell her i am not going to risk anymore questionable parts. also, i will ask Hytec if a aftermarket crum would work.

thats the deal so far. thank you very much for the support. i do really appreciate it. Jim

Do the CRUM chips mate properly with the connector on the back? The bracket that supports the connector can bend back, and the CRUM chip never plugs in. If that is the case, the chips and cartridges may still be good/usable.

If the CRUM chip mates properly and the toner density does not improve within a certain time period, the PCU sends a signal to the CRUM chip to tell it the cartridge is empty. After that, that individual cartridge will always show empty, regardless of how much toner is actually there.

So if you're toner density is not improving:
Is your developing unit seized? Can it be turned manually? I've see the drive end of the mag roller twist right off.
Are the drive gears mating properly?
Is the surface of the toner sensor clean, not caked over with hard toner?
If you run sim 25-1, what sort of readings do you get? It should be around 100 roughly.

It is also possible that you have 2 consecutive bum CRUM chips in the AM toners, had it happen as well. Try OEM toner to see. Some AM toners on these have the spring loaded, sliding toner waste gate and others have a plastic flip type door that must be set. Other issues I've seen are broken tabs on toners not opening the waste gate leading to toner backup in the drum unit taking out rear drum auger gears and also front tube auger breaking, but will not cause the F2 code you have. My guess is you had both AM toners with defective CRUMS

Hi guys, well, the first toner that was in the machine is OEM and half full when it told them to change it. the crum bracket looks fine. the toner and developer as well as drum units are turning fine. the reading in 25-01 was 190 i do believe.

... the reading in 25-01 was 190 i do believe.

The developer is not agitating correctly. The 25-01 must be a lot closer to 100 for you to have a usable copier. 190 is off the charts. The highest I've ever seen is 150. =^..^=
