I HAVE A KYOCERA FS-4000DN PRINTER THAT SHOWS ON THE DISPLAY : CALL SERVICE 7410:0027066 . CAN ANYONE HELP ME WITH THIS POROBLEM , MY PRINTER DOESN'T WORK

Error should be something like CALL SERVICE XXXX:XXXXXXX.
First four numbers are error code, and numbers after : is a page count of device.
Write down first four numbers and maybe i can help you.

Toner motor lock error ,usuall ycaused by using non manufacturer toner ,you may need to get a new developer unit

according to my reading, a flashing power lights indicates a problem you can solve on your own. while a error like you typed would mean something that you cannot resolve without help. a problem like a bad controller, or a bad chip. maybe a eeprom issue.

If Call service appears, turn off the printer, disconnect the power cord, and contact your service technician
Some errors cause the alarm to sound. To stop the alarm, press [Cancel].

#### represents a mechanical error (#=0, 1, 2, ...). Call for service. The printer does not operate when this message is displayed. The total number of pages printed is also indicated, e.g. 0123456.

This woiuld mean you printed 53103 pages with that printer before the error occurred.

Good Luck

I’m happy to assist further over the phone at https://www.6ya.com/expert/norman_d2fa496dce30c65d

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
