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.

Normal 0 Driver could be corrupt.
Disconnect the printer or at least be sure it is turned off. I'd do both and reinstall the CD software program that came with the printer. When the software program asks you to connect the printer to the USB port, do so and it should again work properly.
Hope this helps. Bud

Ibm 6400-008 with P62 error

P-62 error is DC program not valid. The printer cannot find the controller program or the validation checksum is corrupt.
You can try to reseat the flash (memory simms) but it probably will not help. You need to re-download the program (microcode) to the machine and if it still fails replace the flash with pre-writen flash.

If you need a copy of the microcode and instructions on how to load let me know here (I will try to keep an eye on this post)

Usually with this error the program checksum for the printer controller is corrupt or the data controller memory is corrupted.

You can try redownloading the program into the printer or it's possible it also has bad Flash Memory.

Did you try reflashing this unit and then it came up with this error? If not you might need a reflash or a new CMX controller bd.

If you have any other question please contact me I am an ASR for Printronix and they built the 6400's for IBM so I know the pritner inside and out. I also carry all the parts new and refurbished to fix it.

Please let me know.
