These machines constantly burn up fusers. Either paper curls up under the thermistor and pops the thermo-fuse or the fuse just pops on its own. We have replaced fusers and an hour after the tech left they call back for another failure. Has anyone adjusted fuser temp in sim #161. These are the default temps.
Ready temp=160 Stable drive=170 Stable stop=170 Temp full print=170 P. roller temp=150
I have changed a machine in the field to 165 on the stable drive, stable stop and temp full print. Does anyone have this same problem and what if anything can be done. The previous management failed to register machines for warranty so I have a S-Load of fusers that can't be sent for credit. $330.00 for each fuser OUCH
Do you know which thermostat is dying? I had to carefully take off a few covers to test one individually.
Older fusers had an issue where the thermostat next to the heat roller inside the belt would warp and run into the heat roller. The one I had would make a coffee-grinding noise. A recent revision of fusers should have fixed that.
We had a C4035E randomly blow the other thermostat next to the press roller. Replacing the engine seems to have fixed it. *still crossing fingers*

Bily, Have you tried to get a return authorization for any of those fusers? I don't register my machines and when I have a problem it just asks the date of install. After the serial number of course. They do check when we bought the machine and run the warranty for 39 months or the rated amount of copies from that. Or 36 months from install.

My parts man told me KMA connect wont process RA without machine being registered. I will try myself, thanks for the info. Still wondering why these fusers make grinding noises and blow fuses.
Im currently troubleshooting a C6030 code on a KM-C4035E model. I've tried two different fuser assembly's, an engine PCB, and a power source board. It sure acts like it's a logic issue but I'm stumped. Any ideas?

Found out that my parts man was not using the full serial number when entering on KMA. We only use eight digits/characters in our comp system. Now heres antoher question. Lets say I have a Voyager placed in the field for two years and the fuser goes out @ 269K. I get warranty credit for the fuser and replace with another fuser. Three months later the fuser goes bad again. Machine still less than three years old but copy count is 305K. Now I have to use warranty sales. Now I have to go back in KMA and review the eight PO's that I have made in the last three months. How do I know which PO the fuser came from? I just picked one of the PO's that seemd about the correct date and used the invoice number and date. Do I get another three years for the replacement fuser? What a bunch of horse dung!!!!!
BTW the latest part number for the fuser is 302fz9316B. If you look on KMA and track that item number you will see that there have been 12 part number changes for this fuser. To me that means they are junk and they keep trying to fix a bad design.
guys: i decided to extend the sleep mode 240 then set the weekly timer to shut down the color copier @ 7:PM & Turn them back on @ 6:00 am, this formula is working so far. i think that in long term we need to clean or replace the thermistor more often...
billyzoom re the coffee grinder noise. i took one of these units to pieces to work out where the noise comes from and the answer was. inside the heat roller there is a bar that holds the themistor in place and it warps which brings the thermistor in contact with the inside of the roller .the grinding noise is the thermistor grinding away the inside of the heat roller.
ajax we were in a position where kyocera was out of stock so i thought i would be able to fix it .after about 2 hours dissmanteling it i gave up and just threw it back together as best as i could and returned it to kyocers .so the answer to your questions is none and none but at least i found the problem.
Does anyone have a part # or location where you can buy a new thermostat? I have had 2 of these units go bad and was able to fix one with a jumper, the other fix is in progress. Yes these fusers are a PIA to disassemble and get back together, however it is worth the trouble to have at least 1 in stock for these kind of problems.

Our only fuser failure was on a KM-C4035E where the fixing belt walked to the rear and began howling. I took it apart, centered it, and with-in 3 minutes it had walked to the rear again and was howling at the moon. I thought about howling along with it. I still think overall Kyocera is producing very robust equipment.

This issue has got to be addressed by KMA. We have used 44 fusers since this product has been introduced. We currently have 18 units, 3 of which are in boxes in our warehouse, so they haven't used any fusers.
We have a situation again with the same customer, where a fuser was installed at 4:30 pm and at 8:30 am the next day has a C6000 code.
These are not cheap parts, and we stock 1 of each for the C3232 etc, and the C4035. We have not gone more than 2 weeks without using 1 or both of the fusers and have to overnight one to a customer. That is if KMA has them in stock. Otherwise we are taking one out of a machine in inventory, installing it, when the new fuser comes in going back out, installing the new fuser and putting the now used fuser back in the machine from inventory. This is all due to the Order tracking system. If we try and register the fuser from the inventory machine as the replacement fuser, we randomly get "duplicate part serial number" which means the system knows which fuser is installed in which machine. Fun, fun, fun.
Oh yeah KMA warranty covers the part, but not the $100 to overnight and $20 to ship the part back, plus the related travel. BTW, this customer is 45 minutes away.
I have always thought KMA has made tremendously reliable products, this is really rattling my confidence.
I must admit I've gone through quite a few fusers myself. Most of my color machines are CS-C4035E, and I've had two of these fusers last less than 24 hours.
But since we started getting part#: 302JD93054 I haven't replaced a single fuser for the coffee grinder noise (thermal switch comes into contact with the heat roller inside the heater belt). I've had a few heater belts perforated by the customer.
On our in-shop machine I got an extra 5 days out of our fuser after it started making the noise by coating the face of the thermal switch with high temp grease. These fusers are not that hard to disassemble.
I must agree that the warranty is a major pain in the axx. I have three fusers that we can never sell that are designated as "loaners" to get the machines back running until the warranty fuser comes in.
