082 Power Supply 8.5V fail

Can be Power supply or CMX PCB. If CMX the printer will need to be re-flashed after replacing, there is no reasonable way to figure out which is the problem without replacing them.

Where is the 8 meg dramm located?

The 2 memory slots closer to the front of the printer. Under the chrome cover for the cabinet or the top cover for the pedestal.

Table mismatch error ibm 6400


Occasionally you willneed to reload the flash memory in the printer. To do this you will need a PCor laptop, a parallel or serial cable, and the correct flash code file. Thepart number for the flash code file can be found on the configuration printout.If the printer is not functioning and a current copy of the configurationprintout is unavailable you will need to gather some information to enable usto get the correct code for you.
In order to determine the correct flash code for the printer you will need toknow if the printer has any additional interfaces, the part number of thesecurity pal, the model of the printer, the amount of flash memory and draminstalled, and if the customer uses PGL, VGL, or IPDS graphics.
Once you have the correct flash code file you will need to copy it onto thehard drive of the PC you will be using to flash the printer.
Connect your data cable (parallel or serial) from the pc to the printer
On the printer, hold down the Start & Cancel keys while powering on theprinter. Continue to hold both keys down for 5 seconds and then release them.

The default download mode is parallel (Centronics). This is the easiest port toflash the printer through. If you need to change the download port to serial,see the note at the end of this article.

At this point the display should read "Waiting for Program Download".

On the pc, open a Dos window. At the command prompt, change directories to thedirectory in which you stored the flash code file.

At the command prompt type:

filename.exe -pb

where "filename.exe" is the name of the flash code file you areusing.

While the file is being copied into the printers memory the display will showyou the load process and status.

Do NOT interrupt the load process as this can damage the memory and controllerboard.

When the program has finished loading the printer will reset itself.

If after resetting itself the printer displays a Par error, table mismatcherror, or hangs on initialization reload the code again.

Once the code has successfully loaded and the printer has reset itself, poweroff the printer.

Disconnect your cables and reconnect the customers cables.

On certain 475 and 500 lpm models you will need to set the shuttle speed.

On 1400 and 1500 lpm models you will need to set the coil temperature.

On all models you will need to run a test print and adjust the hammer phasing.

NOTE: If you need to flash the printer through the serial port you will needto follow these additional steps.
When you see "Waiting for Program Download" on the LCD press theScroll Up key. The display will now show "Select DownloadPort=Dataproducts".

Press the Scroll Up key to cycle through the available download ports.

When the display shows the download port you would like to use, press the enterkey.

The display should now show "Waiting Download/Port=" and the port youhave selected.

At the Dos prompt type:
MODE COM1:9600,N,8,1,P
filename.exe -pbc1

Continue with the flash download procedure.

When removing the document that prints, how do I remove it from the continous paper without wasting a sheet every time?

Press the view button tear off the paper then press view button again and the printer will bring the paper back down, I think anyway

I replaced the shuttle and need to do the phasing

IMPORTANT The printer must be printing the Phase pattern of “H’s” when the Phasing Value is changed, or the New Phasing Value will not be written into NVRAM. If the value is changed when not printing, the printer will return to its default phasing
value when powered off then back on.
1. Install the ribbon.
2. Load full width (136 column) paper.
3. Power on the printer and set top of form.
4. Press Stop to put the printer into NOT READY mode.
5. Press Scroll + Scroll to unlock the Enter key.
6. Press Scroll + Scroll + Return + Enter to enter the CE Tests menu. (Press all four keys at the same time.)
7. The display will show “SERVICE / PRINTER MECHANISM TESTS”, the first menu item. Press Enter to enter the
mechanism tests menu.
8. Press Scrollor Scrolluntil
9. Press Enter. The printer begins printing all H’s, each line preceded by the phasing index number.
10. Press Return. The display will show
11. Press Scroll or Scroll until “SERVICE / HAMMER PHASE VALUE” is on the display.
12. Press Enter. The top line of the display will show
“HAMMER PHASE VALUE” and the bottom line will show the current phasing index number.
13. Press Enter. The phasing index (followed by an asterisk) will move up to the top line of the display.
14. Press Scroll or Scroll to increase or decrease the phasing index, then press Enter to activate the value as it prints.
Continue to increase or decrease the phasing index until the pattern of H’s appears.

15. When the print pattern is acceptable, press Stop. Printing stops, and the printer automatically enters the current phase
index value into NVRAM. The display shows “NOT READY”.
16. Press Scroll + Scroll to lock the Enter key.
17. Close the printer cover. Press Start to put the printer into READY mode.
NOTE: If you changed the phasing value, power down the printer, remove the shuttle cover, and write the new phase value on
the aluminum shuttle casting.

Where we get IBM printer model 6400 010 print head ?

Its not really a print head, its a shuttle assy, The shuttle takes individual frets are you looking for the frets or the whole shuttle assy? What ever you are looking for i would need the shuttle part# in order to get you the correct shuttle of fret.
