Problem with the fusing unit MX-C311

[davidcorp]

Hello,
I've a problem with a MX-C311, sometimes happen this error code: l4-16 (fusing unit).
I've verified that the pressure release control lever (MLEVP1113FCZZ) is broken. I've also verified that is very very hard to move the "ring" in the pic. It's normal?

Absolutely normal, unfortunately at my location we've come to expect it from any older C311. The MXC32HK kit replaces all the fragile parts these fusers are known for, however you're looking at a lengthy and involved rebuild.

Keep a stock of MXC32FU1 on hand and just be ready to shell them out en masse.

Do you think I've to change the fuser or only the broken part?
I'm not a reseller, I've to find the fuser unit (220-240v) for my copier.

If you're willing to put in the time for it, the flag can be replaced sparing the fuser. Just be sure to use the part number MLEVP1112FCZ3 as it is the improved pressure detect release actuator.

If the fuser is hard to turn I would check the bearings on the heat roller. The first models of this fuser had these bearings fail alot. If you try running a fuser with bad bearings to long it damages the drive gears in the copier.

In May of 2010, Sharp added a rib to the pressure release detect actuator that was supposed to prevent the L4-16 code. Even with the retrofit, they still shatter. Every time I have had this code, it is one of three parts: MLEVP1112FCZ3, MLEVP1113FCZZ, LPLTP7869FCZ1. As mentioned already, the bearings on these things are known to fail. If it is hard to turn by hand, most likely your bearings are shot.

Re: Problem with the fusing unit MX-C311

Looking at your picture it appears that the bearings for the heat roller have failed. If you are not a technician I would recommend getting a new fuser, MX-C32FU for 230v. You also have to check the gear that drives the fusing unit, NGERH1982FCZZ.

What do you mean with "it appears that the bearings for the heat roller have failed"?

Re: Problem with the fusing unit MX-C311

It looks like the gear teeth are rubbing against the cover. I cannot be sure because of the angle of the shot. If it is touching the cover then the bearings have come apart. You either have to rebuild the unit with a MX-C32HK or replace it with a new unit. You cannot order just the bearings because Sharp changed there diameter.

It's only the angle of the pic, it's not against the cover.
It's only hard to move.

Re: Problem with the fusing unit MX-C311

If its hard to move, bite the bullet and plunk down for the whole fuser unit as suggested.

I have not understood what do you mean with "bite the bullet and plunk down for the whole fuser unit as suggested".

Could you explain me?

The labor time and parts costs you'll invest trying to fix your problem would be better spent on replacing the entire unit in 5 minutes.

Ah, but the repair parts are 20 euro, but the fusing unit is about 350 euro.
Maybe I can try to repair...

You ask for advice but wont take it when its given , you will end up replacing fuser , but go ahead and spend lots of time trying to repair the old one .
