Why don't Kyo drums last a lifetime?

[Fer]

Hello, i am a Canon tech and from Canon i know two kinds of drums. Ceramic and opc, opc normaly lasts 60-80k on an A3 machine, while the Ceramics will stay there a whole lifetime, up to 3 Million copies.

Now i learned that all Kyocera printers use Ceramic drums, but they only last 300k. Can somebody please explain how this is possible.

The ceramic drums have the advantage that they last longer than other drums. You can also clean them with water. For example if a customer is using labels and the glue of the labels has covered the drum, you can always use water and a soft cloth to clean them, no probem. But they are also sensible to scratches and dirt. These drums do certainly not last for 3 Million prints. 300k for the Taskalfa 250ci/300ci/400ci/500ci is a normal amount. There are machines that have drums that last longer, but I haven't seen drums that last 3 millions prints. I haven't got experience with the High Volume Kyocera's, but the normal office machines use drum that last 300k-600k.

The CS-8030 and CS-820 can both get 3M prints if ... it's run at high volume and the primary charge is kept in good condition (not arcing).
This same if applies to all Kyoceras. =^..^=

I've wondered the same thing. I'm used to seeing the Canon drums go 3-7 million depending on the charge units, then I see a drum for a Kyo FS-3900 that can't make it to 300k. The DK-320 looks like a smaller but identical version of the Canon drum. The drum even looks great but can't make a good print. My theory is it has to be the aftermarket toner, or maybe Canon uses a thicker coating of ASi (Amorphous Silicon). After seeing some downright awful looking drums put out great copys on Canon's, I just can't shake the feeling I'm throwing away good drums everytime I replace them on the Kyoceras.

Let me put it another way.

Can u refurbish an old Kyocera for cheaps, by polishing the old drum, empty and clean the developer. Clean or replace the corona wire, replace the fuserROLLER?

On the desktop Kyoceras, you can clean the Main Charge Unit (on top of drum unit). Can also vacuum generic toner from developer and add OEM, if needed. Never tried polishing a defective drum. If there's a scratch, toss it and get another one.

Just like every other industry nowadays, there's no money in making products that last forever...

What is the cost of the Canon drum compaired to the Kyocera drum. I am guessing that there is more coating on the canon drums?? So they last longer? Just a guess.

I guess the price of the drum is roughly half of a new machine. More expensive than a Kyocera drum.

doesnt matter if the drum never reaches its target life as the warranty is so good is free.

i heard that can make selenieum at the surface for drum to live long life that's true!

if you're looking to refurbish the fs series printers, leave the drum alone but buy and replace charge rollers., cleaning them won't last even if it makes them look new

Charge rollers? Didn;t they use scorotron charging?

Corona wire charging, actually. No scorotron or charger roller. For Canon and Kyocera. =^..^=
