MX-M354N Undertoning

[ZOOTECH]

disregard my previous post, was thinking mxm364 series this is a mxm264 series (capricorn) there is no 46-74 or 46-24 on this machine. you still have to do 25-2 without toner cart in machine. When you go into 25-1 it will show the toner density value . is it above 140 .

faxman28 is right again; I mistook the model number also, please disregard all my previous posts - I don't know shite.

Sharp is getting to close / confusing with model numbers again , I keep getting the m354 and m364 mixed up. Off to have some winter lager at the local Ale House.

If your 25-1 and 2 are good then have you checked your side door transfer/sep unit?

It was at about 110.

[mbcruzin]

It was at about 110.

Default value is 128

EE-EL is at 78
EE-EU is at 178

At 110 your not that under toned. Can you upload an image of your copies?

[faxman28]

It was at about 110.

is 110 after new dev and 25-2 or when copies get light. 110 value should have more toner in dev unit from default 128 value. the toner value below 128(or reference value from 25-2) has more toner and the value above 128 (or reference value) has less toner in dev unit.

Yes, that's after a DV change.

[Jhonjon]

Did you replace the Developer? if yes, after the calibration you said the value is 110 it is in range it must copy well after the DV replacement...Did the undertone comes after a couple of hundred or thousands of copies? if yes try to check the toner itself maybe it is not dropping a toner properly thou the clutch is rotating or try to test also a good DV unit...

I should have completed this thread a long time ago. The problem turned out to be the toner clutch.

NOW, I have another one with the same issue - undertoning. I'll change the developer and it will run just fine for 3 to 6 weeks. Then out of the blue, undertone.

I have tried a new toner clutch. I'm thinking a new drum/charger unit and a toner sensor?

It's throwing a F2-40 code as well.

I've had a couple throwing me that F2-40 code. It was worn out rear mag bearing...(replaced under waranty).
