Warming up issues on MX's

[hammer]

Hi Guys, just checking with you all. I have two MX's, one in the field and one in the showroom, an MX3500 and an MX2700. Both of them are slow to warm up with "warming up" on the display. Both have latest version firmware, and both are not old, less than 20k on each. Any ideas?

Is it just slow warming up or they don't come to ready?

There has been problems with the Thermistors in the F section.. see SharpTechBulls

These machines take four minutes to warm up then you can add more time for process control to do its thing.

Process control!!!! ARRRRRRRGHHH!!!

When I was working on those I had a veritable plethora of compliants about the process control thing.

And no plethora is not a Chrysler product.

It does take a while to get through process control. How slow is "slow" (in minutes and seconds). =^..^=

The specs are:
2700: 80 seconds *the value may be increased if process-control processing is executed.
3501: 240 seconds or less *the value may be increased.......

Simulation 44-28A defaults to YES enabling process-control at initialization. I don't really expect any harsh consequences for selecting NO disabling process-control at initialization. Is that first copy speed that important?

Keep in mind that if image quality varies significantly you may have to restore the original defaults.

Warm up issue

Hi Guys, it's not a process control thing. The machine just sits there in "warming up" condition. I was working on a machine beside it for about an hour, and the whole time it just said " warming up"!. I switched it off for a few minutes, then powered it up again, and it came to ready. I'll check out the tech bulletins with sharp and see what i find there.

If as you say it just sits there..

Remove the F Section.. turn it over.. under an opaque white plastic cover there are 2 Thermisters.. press the re-set buttons...

There is a TechBull about that........ but I can't find it at the moment...

warming up issue

Thanks for that John, i'll give it a go. I checked the Sharp website and couldn't find the bulletin either. I'll let you know how i get on.

I've had problems with them in the past.. ended up replacing both on a couple of machines and not had many others go.

Now just have the occassional Re-set after they had a few jams in the F Section.

Warming up issue on mx's

Finally got a chance to look at the machine in our showroom. The thermostats were fine, but the thermister had a very small bow in it which was enough to keep it slightly off the roller! Very strange for a new machine that never had any work done to it. Anyway, job done. Bring on the next one!!!!

Good thread..!!!
I went to a brand new MXM200D today that insists on warming up after each copy job.
i.e:you do a copy job...it completes and as soon as you hit the START button it will display warming up...then print the job.
To my mind it's a few seconds out of their miserable lives but the customer is moaning....I've adjusted every special mode setting I could see with no noticeable difference....I guess it's time to check the thermistors from the sounds of this thread.
