the 7410 error may be a drum unit that is not pushed in properly or it could be the following
defective drum EEPROM drum needs to be replaced or
defective engine PCB
the above suggestions assume that it is an original Kyocera drum
hope it helps

this error indicates a problem with the fuser unit.
if you are an end user, you will have to check warranty status with you nearest service agent and have the fuser replaced free or get a quotation if it is out of warranty

Basically, you remove the cartridge and developer all at once, then remove the waste toner bottle, then push the grey tab in to release the drum cartridge (be very, very careful in removing and putting back in. Any scratches on the drum and you will enjoy black spots permanently on printouts).
On the right side of the grey charger section is a tab you can use to release it. Do this, then put the drum away in a light tight back to prevent damage to it.
The reason why this Kyocera printer doesn't have the primary charger wire cleaner is because it did away with it. It now charges via a black fuzzy looking roller on top which is like the secondary corona charger wire, which then applies it to a roller, which then applies it to the drum. I think this is nice since it should prevent printer quality problems better since there is nowhere for oxidation to really collect. But, OTOH, it does happen anyhow.
I cleaned mine off and the streaks disappeared. I used a non amonia based cleaner to help, since I didn't find any dust on it to begin with. Whatever you choose, do not get your fingers on it, or it will put oil onto the rollers and that will make it worse.
Worked for me.
