Classic, do you report them to Sharp?

I know, we've had numerous failures also but not that quick.

Just saying it clearly isn't helping, have you mentioned it to your regional technical specialist?

I don't think anyone bothers to because ours thinks we are the only dealer still having issues.

Yeahhhhhh I've checked in with him a few times about it, but just plays it off as it seems others don't have any issues. It's the same thing with the developer pull issues we've had for years with the Phoenix/Phoenix2 models.

Sounds familiar, maybe if we all demanded recompense for failed parts they'd take it a bit more seriously. Its gonna cost us a fortune if it carries on like this.

I didn't do the procedure on new machines (because it was theoretically done in the factory), but most fusers failed before 150k.
Since then, I've been checking fusers on installation, and only ONE machine was OK when it left the factory.
Sharp France doesn't give a damn and pretends that I'm the only one with this problem, as with the CR4s, CR3s and so on.
I retaliate by telling them that I now only push Epson instead, and during training sessions I spend my time pointing out engineering flaws that aren't present on the competition.
I don't yet have a BP-C533 C542 in my fleet (as I'm forcing the EM-C800 and AM-C400), but it seems to be the same crap as the CR5 in terms of fuser.

These BP fuser belt units are not very strong and steady. Its just the film rotating on plasic with no gears or bearing, it just turns with the pressure from the pressure roller. With no web, and customers who print lots of heavy colors such as photograps, I have seen toner buildup on the seperation plate which hardens and causes noise, jams and starts to skretch the belt causing premature wear. These 3 things have been helping me somewhat....always check and clean toner buildup on the seperation plate of the fuser on every visit, check eco settings and make machine go to sleep mode within 5 minutes and last thing make sure firmware is the latest.

We also set every BP to auto clean the fuser every 25k. One customer we have it clean every 10k. So far, even on the 71 series, fuser have been lasting a lot longer.

Are you all doing the meadering process correctly?

The fuser must be cold to do the procedure correctly.

So once rebuilt, place it in the device, keep the duplex door open and boot up the device.

Once booted up enter simulation, go to sim 6-8, close the door and start the meadering process

Never had an issue if you do the procedure correctly

As stated above, do not touch the fuser during the run up process once the device has been unboxed, it is not required

Only to be done once rebuilt

Thanks, but the meandering adjustment is not the problem. Did you read the original post? Also you sound just like someone from the sharp hotline. Quoting instructions from the manual.

I have talked to my DSS till I'm blue in the face. Also numerous warranty's and other non warranty cases logged in their Case Management System. Sharp knows there is a problem, and they almost always act like you're the only dealer with the issue whatever it may be. This is the main reason I made this post.

If the machine is in warranty 180 days they will send another flawed fuser, but if the machine is out of warranty you will run into a stone wall . I have turned this over to our GM, because my DSS is now denying their is a problem and trying to find a way blame us. It's infuriating and it is costing us a lot of money.

Thanks for the advice. I'm sure that helps a little. We do these things also, yet still they fail. Sharp really needs to go back to the drawing board.

If you think it's costing you a lot, imagine how much it will cost Sharp if they admit there's an issue.

It's all smoke and mirrors, much cheaper to blame it on techs, end users and poor quality paper.

I used to like when they had the collars on the belt unit so it wouldn't meander left or right(and it never did, never had an issue until well after the maintenance interval)... then laughed when they said they put the meandering adjustment in to prevent the belt from meandering left or right.... and it's been nothing but issues ever since. We only ever had one monochrome Phoenix 1 model out there, and it never had a fuser issue. Also only had to rebuild 1 or 2 of the monochrome Phoenix2 series machines, and have done 7 myself, and we have 4 other techs who have each done a handful at least, too. Just silly.

Yesterday we had someone from Sharp in our shop and he told us, that Sharp is working on a solution and they are testing at the moment in Japan

Maybe they'll be putting a web back in, and NOT use the meandering adjustment... HA, if only.

We have 111 BP color A3 models in service.

We have replaced 14 fusers and 4 of those were in one machine. The first fuser for this machine went 397,690 and the replacements have averaged 50,561.

Fuser replacements by speed
31 - 1 each
36 - 1 each
45 - 3 each
55 - 7 each
65 - 2 each

The average life for those 14 fusers is 159,242. There are many machines in the field that are still on the first fuser and are nearing 400K.
