Fuser problems Phoenix/Griffin(2)

[boutn]

Are there still people experiencing problems with the MX601FU MX608FU MX409FU MX408FU fusers?

We have a wall of fusers in our shop to rebuild which keeps on growing.

Mostly fusingbelts that are burnt, pressure rollers with massive buildup causing jams or paper rolled around the roller.

These almost never get to their respective lifetime expectancy, which is becoming a very costly situation.

Some here are saying they change the fuser temp to +10, others to +5, others to -5. So which one is it?

Some install the cleaning rollers (DUNT-9555DSZZ), some say they are crap and dont work at all.

Last thing i read was the German report about the latest firmware and the autmatic cleaning pages.

Seems to me these fusers are crap in general...

Re: Fuser problems Phoenix/Griffin(2)

I've seen a lot of issues Not making it to life, having to change fusing harness because of random HX's Codes. I'm guessing sharp went cheap on them because they are crap for the most part. Changed 3 harnesses so far this year and changed 2 fusers out because we didn't want to deal with rebuilding them only for them to crap out within the week ( happened once already)

I agree with all your comments above, don't add the extra cleaning roller kit, its just more junk to gum up and wear out
the rollers, or heat belts. Remember the MX2600 fusers, they had no cleaning other than the metal rod, and if you took that
out the fusers would run long past the pm specs. All them rods did was poke holes in the roller and make a noise, jumping on the roller.
I am getting some fusers to make 200k or more by cleaning the fuser blade at every call, stretching the springs on the blade
to make them alittle longer so the blade don't rub on roller so hard. And check all 4 coronas every call to see if the blade is leaking. If
they have toner dusting on them the blade is leaking. If you get them changed soon enough it don't dirty up the fuser rollers
so fast. Sorry for the winded reply but this about all I get done is deal with these fusers and the MSATa ,HDD, MFP issues, which cause constant
restart attempts, sluggish response, and no startup problems. I have found these issues on machines with really old firmware, so we try
to upgrade on every call. I'm done venting. Thanks for reading.

Don't be upset at the machines, be upset at Sharp for putting out crappy fusers. Seemed like for a few years we had the worst time with them, we kept complaining and nothing was done, other than setting the energy save to a minute, instead of maxing them out like we used to be able to do. It's mitigated a lot of the issues, but still have more than we should.

Re: Fuser problems Phoenix/Griffin(2)

We have been following a procedure that isn't in the manual but was relayed to us from our Sharp rep. When you go to replace the fuser, power up the unit be sure to get the install fuser message then power down the machine and then install the new fuser. It supposedly resets the thermistor values. I've been doing this for a few years now and it seems to help with the longevity of the fusers. Sometimes I even get rated life out of them LOL

Good luck

At this point, we'll try just about anything. Also didn't help when there was a few months maybe a month ago where fuser parts were backordered.. ridiculous.

also check the ends of the stripper plate.. they bend.. then it rubs the fixing belt.. they arent supposed to touch the belt at all.

Re: Fuser problems Phoenix/Griffin(2)

We had a lot of issues in those machines for HX-XX codes.

We always thought that were simply crap and moved on, refurbishing fusers and swapping to the customer.
But, after a deep investigation we noticed that, a lot of times, after errors were not resettable, we found Fuser Belt completely out of position, on the left.
And while on the left, fuser belt was activating "Meandering detect lever and sensor", causing the fuser to stop. With Error "H"

Now we are tightening a little bit fuser pression and seems to be a good way to reduce tech calls.
Dont' want to say "eureka" but let's see what's happens.

Hope to here from your experience.

Just give it a try.
Have a good day.

Re: Fuser problems Phoenix/Griffin(2)

L4-03 This monday for a rebuilt phoenix fuser. MX-407FU1.
Fuser at 12%, 6 months in field.

Yesterday, my co-worker was going CSI on it, and it turned out to be the rear fuser pressure roller bearing we replaced. Turns out these were non-oem bearings, because they were on back-order by Sharp.

We went through all the new bearings, and we found that a few bearings ARE NOT smooth to turn, like if the balls inside were intermittently "catching and locking" into place, if that makes sense.

In case someone else runs to this problem.

Good luck.

We were using non oem bearings on some of the older models. We found the grease came out real fast and then go bad right away.

Do we know if this only applies to Phoenix/Griffin color or also the Phoenix-B/Griffin-B Black and white?

Re: Fuser problems Phoenix/Griffin(2)

From my experience, these fusers often have a problem with inadequate or uneven fuser pressure. You are relying on those two little pressure springs to do all the work. Sharp doesn't provide for adjustment, though they DO provide new springs with a new fuser belt assembly. First Sharp was driving the sponge roller in that fuser belt assembly, then they removed the gear. They made a design provision to be utilizing a cleaning roller in the fuser, and that wasn't the answer. They clearly were having problems. IMHO, they need to hire an engineer from Xerox or Konica Minolta.

according the sharp guys the preliminary units that were shipped out for review before release actually had cleaning webs. they removed them when they went to production
