I want to buy a used model MX-4071. I want to know your opinion about the device. Is it a good device? Are you satisfied?

The Fusing Unit on this machine is the absolute worst in my opinion.
If you or your customer are going to print a lot of pictures or documents covering the whole paper you should be prepared for a lot of paper jams.
i've had countless times where papers are getting stuck to the lower heating roller and causing jams.
My company even preffers going for the older MX-4070 because of just how of a bad experience we've had with the 409-fusers.
Printing normal documents usually works just fine and the machine other than that is a solid one in my opinion.
Hope this helps

Has this fuser issue happened to everyone, or was it just a problem you personally encountered? I’ve seen similar issues with older devices like Sagem, but when I used a newer model like 3114, I never experienced such problemsThe Fusing Unit on this machine is the absolute worst in my opinion.

No, it doesn't happen to everyone but it happens too often to recommend using this machine knowing that the user will print a lot of pictures / documents that covers a lot of surface area on the paper.
It's a known issue with the whole machine series (CR4.5)
Sharp released a firmware that is supposed to clean the fuser at a set ammount of prints but from what I have experienced the cleaning paper itself gets jammed from time to time so we stopped using that feature.

Same have a lot of these machines in the field,for some reason pull coverage image prints tend to curl and jam in the fuser.Comment

Expect half life.
Rated at 300K and we average 152,167 for the fuser on the MX-4071. I did not include the 3071 or 3571 in my average. This is calculated from 28 machines.Comment

We have a few, and absolutely no issues. As far as jamming in the fuser, the adjustment of the fuser entrance plate is critical. We remove the plate, clean it w/ citrus solvent, mark the center of the adjustment hash marks w/ a very fine Sharpie, and then when you reattach the guide, you can easily see how it is adjusted. Typically, I start exactly at the center hash, but often have to move higher to get the best performance. 409s and 407s are really the same design, & use the same belt assembly & lower roller. Sharp doesn't re-invent the wheel, ever.... There is the temptation to rebuild these fusers w/ $75 worth of Chinese compatible parts, & save $400, but you have to source parts well. Luckily, I have a nephew who works for Xerox in Shanghai - never hurts to make connections there.Comment

I guess if you're only getting 150K, you're a good candidate for rebuilding these w/ aftermarket parts. My quick calculation is 28 rebuilds saves $11,000 - starting to seem like real money. I know that I could rebuild 28 of these in a week, and I don't know any techs making $11,000 in a week.Comment

I'll agree with everyone on the fuser for the whole CR4 CR4.5 range (the Mono B-CR4 B-CR4.5 are fine)
But I have seen less maintenance after running the 50-10 and 50-05 calibration, changing the sleep to 3 minutes, and using these switches :
55-01
SW-32 67 Nettoyage four 1k 01 5k 10 10k 11
67 for 10k, 7 for 1k (too much), 6 for 5k (rare occasion)
SW-22 8 5070 et 6070
SW-31 1 3071 à 4071
SW-31 2 5071 et 6071Comment

Besides the issue of paper sticking to the hot roller, which I believe happens with some machines, are there any other problems? My current machine is an MX-3114. Do you think I should upgrade to an MX-4071 or not? I'm having doubts after reading some reviews

The 3114 may be a better fuser, I think it has web cleaning rollers which the 4071 has no kind of cleaning system. The problem we have with the older models like the 3114 is the plastic around the fuser gets brittle and dry rotted, foam seals in drum units turn to a goo like substance ect.Comment

I wonder what parts you swap while rebuilding these...
Because after replacing the lower heater, the fusing belt, the modified exit roller, bearings and bearing holders, bearings on the lower heater and separation plate, i dont know if your $11000 is correct.
edit: i forgot to add the time you spend rebuilding these also

The fusers used to be bad, but after setting adjustments and the cleaning sheet, we've experienced significantly less issues. We have DV pulls constantly, but that could be aftermarket toner/waste boxes.
Otherwise they're great machines. That being said, if you're going to buy a newer machine, why not go with the latest model? The BP series is pretty good so far, other than the fact that we definitely shouldn't clone settings over from old models.Comment

"I want to buy a used model MX-4071"
But why not recommends an AM-C instead of a BP ? I really fuckin love theses models.
Don't try to make me believe you don't get wet in front of that print head.Comment
