IBM 6400 Matrix Printer - Answered Questions & Fixed issues

Check the link http://www-01.ibm.com/support/docview.wss?uid=nas8N1013805 Hope it helps

Printer will need to be re-flashed, you will need to get the correct firmware.

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. CMX MRP provides IT Parts Product Supplies and Services Power Supply MRP provides IT Parts Product Supplies and Services

Driver, the printer can't even hold one page in memory let alone many pages.

Bad CMX PCB, you will need to flash it after replacing it. This is the part you would need MRP provides IT Parts Product Supplies and Services

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.

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

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 Scroll↑ or Scroll↓ until
“PRINTER MECHANISM TESTS / HAMMER PHASING” is on the display.
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
“SERVICE / PRINTER MECHANISM TESTS”.
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.

A reflash might do it, we offer that service in-house. [email protected]

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.

Might not find any anymore, IBM has discontinued and no longer supports the IBM 6400 series printers and or any printers at all. If you need some support or printer parts please contact me. Rory 708--597-4222

Might be your gap is set to high. try moving the right lever from A to B for example and see if it clears it out. Also might be your parallelism, you will find to hex screws on the right and left of the platen assy that u can adjust. This will balance out the shuttle if one side is printing to light and another is printing to dark. Rory 708-597-4222

usually u get those on mod 14's and up and it could be a few things (i would try in this order from lowest to highest priced) coil temp needs to be set, hammer bank cables, shuttle and or cmx bd need to be replaced. Rory 708-597-4222

you can first try power off and power on, if that doesn't work you can try disconnecting and interfaces you may have connected to the unit like a 10/100 card or twianax card. If you don't have any of them cards attached then you might have a bad logic bd, or have a logic bd that needs reflashing. Rory 708-597-4222

it seems your controller bd lost its config somehow. They do that if the NVRAM has gone bad. You might need to replace the Controller bd (CMX BD) Rory 708-597-4222

The Problem you are having is due to re-inked or remain ribbons. You need to use OEM Printronix Ribbons, I have new in stock if needed part# 107675-001 they come in a 6 pack. 708-597-4222 Rory

Hi there, I hope you haven't throw away the printer.. :)
i face similar problem.. its solve by tightening the ribbon latch screw that secure the latch to the ribbon motor.

There are several sites listed that offer drivers for the IBM 6400. Google IBM 6400 and select any site that looks suitable, try another if it does not offer what you are looking for. Good Luck.

Hi

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.
