Kyocera Ecosys FS-3900DN in HP emulation mode

Have you tried just setting it up as an HP? Kyocera machines emulate HP.

The message is indicating that you do not havea real Kyocera toner installed in the machine.

Will just reflashing the firmware fix this?

I have replaced the EEPROM (as per my post near the top) on a few of these, so that the printer will come to ready and then flashed the EEPROM via parallel port with upto firmware.

In the menu of the printer yo can change the emulation, try selecting a difernt emulation to see if that corrcts the proble.

whai is the defect my kyocera ecosys fs-3900dn has error code call service 6000.0240336

The Call Service 2200 is a drum motor error. The motor or gears might need to be replaced. First remove and re-seat both the developer and the drum unit. The developer is directly under the toner cartridge - lift it up then out first, then open left side door remove the waste bin and press the button on the drum unit just above the waste bin pull the unit out (carefull not to touch the drum surface). Re-seat both units. If this does not work call in a Kyocera Tech.

It is a "mechanical error". The part after the colon is the number of pages printed. It's probably worthwhile taking the trays, toner and cartridge out and opening all the access doors and checking for something obvious before calling in an engineer.

Try changing print driver and switch emulation to kpdl auto if not already there. If this doesn't work go to properties on driver under font and switch to bit map. Don't do this step unles yo have to it really slows down your printer.

Try downloading the manuals from Kyocera :

Please take a moment to rate this solution. Thanks.

See if this is set to pcl6, make take care of it.
