Kyocera fs-3900dn 0150:0000007 error - Kyocera FS-3900DN Laser Printer

Means that the laser unit is off. You should check the cables for the laser unit

Hi,
This problem is caused by a poor contact in the fuser connector terminals.
Check both sides of the connection (in the printer and fuser unit) In most cases we will find small pieces of paper inside printer connector causing poor contact between printer and fuser unit connector.
Hope i was of any help. If i was, please rate me.
Thank you.

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.

The 7410 is a drum installation error code. This is typically caused when the waste bin is replaced. Open the left door and push on the drum unit just above the waste bin, usualy a click will be heard when pushing it in. Then power cycle the printer. This should fix the error message.

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.

Right click on the printer icon and choose properties. Your emulations are listed there.

0150 - Engine PWB EEPROM error. Detecting engine PWB EEPROM communication error.

Solutions:
1. Switch the printer OFF; unplug the power cable; wait 20 seconds; plug in the power cable; switch the power ON, If the error comes back follow the next solutions:
2. Update / Burn the latest firmware version. You may need to call a Kyocera Service Provider because you need a CF card (compact flash memory card) and the FIRMWARE.
3. Replace the Engine PWB (a board) - again you have to call a Kyocera Service Provider.

did the error came on after replacing tonercartridge ?

open the door at the left and push on the drum till you hear click, problem should be solved afterwards.
