Kyocera printer FS2400 shows me error code 6400,what can i do,,,,pls helpe

SOURCE: error code C 6400

This code is a fuser problem code. Follow the procedure below. If the code does not reset or comes right back then: you will have to check the thermistor, thermo fuse and fuser lamp. If 1 or more are defective then replace. After you replaced the defective part you will have to clear the error code again.

Here's the way to reset that fuser code;

First open top cover then turn on power.
press system menu/counter
arrow down to service
press and hold start, # then enter keys
arrow down to maintenance
press enter
arrow down to Sim 163
press enter
select execute
press enter
turn off power then back on

SOURCE: p62 error code

The IBM 6400 printer uses internal programming software that is specific to the printer based on installed interfaces and graphics options. This software resides in flash memory and when the printer is first powered on the software is executed. During this process it initializes the various processors on the controller board, initializes the optional interface cards, and then loads the necessary operating settings into dram. If the programming software becomes corrupt it will fail during startup, giving you the DC Program not valid error or a number of other error messages. The solution to this is a reflash of the printer. Unfortunately, the flash software is proprietary to IBM and they will not distribute it to anybody. The only way to get the printer reflashed is by calling IBM and having one of their engineers reflash the printer.
