Kyocera 2-series Question

[Dark Helmet]

Sorry to be late to the party.

When the xx52ci and xx02i series came out, the fusees didn't seem to last as long as they should. It didn't seem to matter if it was big machines or little machines, the fusers just didn't seem to be going their life. I think it was on this forum I ran across a solution that I have incorporated into setup.

U346 > Selecting Sleep Mode > Fuser Power Mode > Off > Start > Machine will call for reboot > Reboot the machine

Since incorporating the above into my setup and deploying out in the field, I have experienced waaaay less problems with the fusers on theses models. I continue to do this with the 3 and 4 series. In fact any Kyocera model that has the option of U346 > Selecting Sleep Mode > Fuser Power Mode, I turn it off.

I think that leaving Fuser Power Mode on makes the fuser stay on most all the time causing premature wear. Kyocera may have address this with firmware, but I still turn Fuser Power Mode off.

I hope this helps.

Some one posted a document on that mode. Energy saver default is like 1 minute to sleep which stops the fuser from rotating. Of course 99% of people would never accept that so the machine gets it's timers cranked to max (bad bad bad). The fuser will sit and rotate for hours. U346 with fuser power mode off if i recall lets the fuser rotate for 1 minute while the machine is idle before it turns off the motor. This will cause the fuser to make the majority of it's life before the bearings blow up.

Silent mode is a better option. As soon as the job is done the fuser stops turning which results in the fuser making life. This works well on the TaskAlfa A3 devices. DO NOT do this to A4 or Ecosys A3 devices. The machines will run at half speed and don't have the rotation issue so there is no reason to turn it on.

Some one?

Both the xxx2ci and xxx3ci have more vivid colors.

The original fusers will squeal and give C6220, C6030, C6600 and C6770 errors. A couple of the metal shafts are made of very soft metal and very quickly wear down. The 5 second diagnosis is to carry your fuser over to counter, tip it onto the outer side and bump it on the counter. If it dumps a tablespoon of rust dust out of each end of the fuser you can be sure that you need a fuser replacement. The FR-8550H fusers seem to last longer than 170K. I think we've replaced EVERY original fuser.

For C2300, 4214, 4204, 4203:
All caused by the fuser. The belt rotation sensors detect differences in front/rear belt rotation speed. The endcaps slip on the sleeve ends ... fixed on FR-8550H fuser.

The imaging components seem to make yield.
The primary charge rollers have all the same sort of defects that you've seen of the Alphards.

The developing unit lock buttons tend to pop out by themselves. The best solution seems to be driving a small sheet metal screw into the edge between the button and the front cover:

For dog-ears, paper skew, 0523, 0524, 6511, C8100:
PF-7110 intermittent dog eared on new 4003 series

For 0512, 0502 misfeed:
KM-3552ci jams 0512, 0502

For 0533, 0534 we've had to increase page separation. You've probably had to adjust page separation before. Decreasing the spring tension increases the page separation. I think of it this way: More spring tension makes the separation roller follow the feed roller more. Less spring tension makes the separation follow less, resisting multiple feeds.

For 0413, 0502, 0000 won't clear:
A dusted over registration sensor will cause this.

For C8020, C8030:
The punch motor fails.

For C9040:
The original lift plate breaks at the rear post.

These machine use the empty black toner cartridge as the waste receptacle. There is a switch that is flipped on the cartridge when you remove the empty, so the machine can tell the difference between a full and an empty. So if the enduser takes out an empty black toner cartridge and tries to put it back in ... well it won't go back in. We get lots of calls for such things. It doesn't help to tell the enduser that shaking an empty toner cartridge doesn't help. ITS STILL EMPTY!

Hey Black dog not sure if you have done this or not, but we have used high temp glue on the film of these fusers to reconnect them and it has worked great! allow them to sit for 24 hours and then glue the other side. You can't really do it in the field but you may not have to throw every fuser in the dumpster.

To check if it will happen on the system, you has to take care for U167.
I created short information for our techs regarding this issue and i will share with you.
(data from our 25ppm show room/ training system, no real kind of usage, but a very good sample)

i do not recommend the use of high temperature grease because it can be counterproductive.
If the FK unit is always rotating with low speed, the length of the belt increases in early stage and therefore it will slip.
The rotation is controlled by 2 sensors.
As a result, the front and rear sensors send different signals and the C6xxx appears.

Just to clarify, Scot appears to be gluing the sleeve to the endcaps, not greasing them. I have had limited success with that. The glue I used did not survive fuser temperatures most of the time.
