MX-M354N Undertoning

[Buddy]

Hi Guys,

Other than the usual - clean toner sensor, SIM25-2 properly executed... - are there any problems with toning issues on this machine? I sold 3 of them at roughly the same time and there's only one that keeps giving me grief.

Thanks!

Haven't had any undertoning issues with these but we mostly have 465's. Pretty much the exact same engine and supplies. What's the copy count at? What are your 25-1 readings? Have you tried swapping DV units?

Good luck.

Re: MX-M354N Undertoning

there is bulletin about toner clutch sticking and causing overtone, since clutch is faulty could also cause undertoning, also calibration needs to be done , like on color mfps. Also there is drum patch sensor in transfer unit that reads density patches on drum.

Thanks guys. Readings are all good (once I replace the developer). I ran 10-1 several times and it didn't tone up very much, but I did verify that the clutch was turning. If I can get a hold of it, I'll look into the tech bulletin. Thanks again.

These Jupiter3 models require the toner cartridge be removed when running 25-1, 25-2, and when transporting/delivery.
TC 25-1
"NOTE: The toner cartridge must be removed before executing this simulation. If this simulation is executed with the toner cartridge
installed, toner will be forcibly supplied to the developing
unit, resulting in over toned and a trouble."
Your drum unit isn't pulling toner is it? Could be a HV problem.

Try running sim 46-74
the black fill will come back

Is the machine level? do you find toner piles in the back/front of the machine? How is the humidity in the office? I deal with the last one a lot along the coastal area in the summer. Images will looked undertoned when the humidity is to high.

Re: MX-M354N Undertoning

Thanks Tee, but what is 46-74? In my book the highest 46 is 46-63.

Thanks MB. Yup, it's level and low humidity. It's definitely an undertoning issue.

If there is no 46-74 use 46-24.

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?

Re: MX-M354N Undertoning

It was at about 110.

Re: MX-M354N Undertoning

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?
