Question about IBM 6400 Matrix Printer
When you power on the printer, do you hear the fans kick in? If you checked the Maint. Man. skip steps 1 & 2, almost 80% of the time its CMX brd, not knowing your 6400 model? Part# for CMX 40mhz 157450-901, older models have 155802-901 CMX 25mhz V5.5...
Oh yeah if u don't hear fans kick in when you first power up, 80% jumps to 95% chance CMX bad.
I hope you have a current configuration print out! it will save headaches and a lot less down time...

I suggest you get a sheet of Card Stock (Heavy
paper) and place it in the feed way. Then press the print
button applying a slight amount of pressure on the Card Stock so it
will feed through the printer. The reason for this is in some cases I
have been able to clear the paper track of debris that was deposited there
Worth a try, as I have fixed a number of printers this way, saving costly repairs.
Hope this helps. Bud
