IBM 6400 MODEL 9

Customer claims the message 'end of forms' displays every time a 'file' is sent to printer even though there are forms loaded in the printer.

When the forms are removed from printer, the printer will give an alarm condition and display 'load forms'.

I have not been to customer site as of yet and cannot give you any more information, but thought you folks might be able to give me a 'heads up' on this situation.

Thanks for your attention to this matter.

    Finally got a chance to look first hand at the 'end of form' problem with the

    IBM 6400 model 9.

    The printer will print several pages and then give an end of form message even though there are forms still loaded. The end user will press the Stop

    Button then the Start Button and printing will proceed and it will print a few

    more pages or may print only one or part of one before issuing the same message again and printing stops.

    I am currently trying to acquire a Service Manual for this printer.

    The end of forms sensor located between the platen and printhead is a

    unusual configuration. It appears to be a photo-optic wheel (regularly spaced cut-outs in the wheel) which is turned by the paper as it line feed upwards during the printing process. This wheel is held by a spring loaded

    arm which is moved back by the pressure of the paper being loaded.

    My question: are there two sensors involved here? I assume that the motion of the wheel as it is being revolved by the paper accounts for one sensor, but is there a sensor involved with the action of the arm holding the wheel when the paper does run out? The action of an arm or lever when paper runs out is something I am more familiar with. This rotating wheel is new to me.

    Thanks for very much to 'Machone' and 'Jackboy' for their responses for my earlier questions concerning this machine.

The sensor with the wheel is the paper motion sensor, The other one is the paper present sensor. Apart from these sensors needing a clean they never really go wrong. However, if your printing on black backed or shiney/reflective paper i.e labels the paper present sensor can cause problems as it cant get a reading. there is a fix for this, reseat the sensor 90 degrees so that its facing the wheel sensor. On the wheel you will see a 'flag' which moves in front of the sensor when paper is inserted, you need to paint this flag white (tipex will do) job done, seen this problem quite a lot.

This seems like a micro switch or sum such is not making/is making when it should or not.
The from load in a stack in the base to I guess there must be a wight sensitive device under the load platform.- stuck in or out.
Take a look at the web site.

Try taking canned air and blowing out the sensor. The wheel turns as paper moves, and the optical sensor sees the slots going by and knows it must have paper. If it doesn't see the slots anymore then there must be a paper jam.

Have been through this with a 6400 a few times, Jackboy is correct, it's a sensor which has gone belly up and needs to be replaced. Had to get an engineer to resolve it, not a major job as far as I am aware, however if you have never done it before seek advice. That is the only way to get rid of the message permanently.

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.

Do you get x64 printer drivers for an IBM 6400 print device, or is it best to just use the Generic Text driver ?

Load the drivers from IBM's web site. But.. depending what Windows ver. you are on go to install new hardware. Windows will find the drivers itself.

The print is only clear on the left side of the forms...

Platen Gap Adjustment (Figure 35)
IMPORTANT Only do this procedure if the original equipment shuttle frame assembly or platen has been replaced by a new or
refurbished unit.
1. Prepare the printer for maintenance (page 338).
2. Remove the shuttle cover assembly (page 357).
3. Loosen the platen open belt (page 415, steps 2, 3, and 4).
4. Raise the forms thickness lever (1) to the fully open position.
5. If you are adjusting any model except the 6400-i20, select a 0.011 inch (0.28mm) flat feeler gauge.
If you are adjusting a 6400-i20, select a 0.012 inch (0.30 mm) flat feeler gauge.
ATTENTION Do not force the platen against the feeler gauge. Damage to the hammer tips will result.
6. Insert the feeler gauge (2) straight down between the hammer bank cover plate (3) and ribbon mask (4), within four
hammer positions of the left end of the hammer bank.
ATTENTION Adjust the platen set screws less than 1/4 turn on one side, then check the other side. Adjustment sensitivity is
approximately 0.03 inch per revolution of the set screw. Also, insert the feeler gauge no more than two inches down
from the top of the ribbon mask.
7. Gently close the forms thickness lever (1). As the platen is closing, gently slide the feeler gauge up and down, keeping it
between the hammer tips and ribbon mask. If the feel is too tight as the platen closes, adjust the 3/32 inch set screw (5)
counterclockwise. If the feel is too loose, adjust the set screw clockwise. With the forms thickness lever closed all the way,
the feeler gauge should contact both the tips and the ribbon mask and move with light friction. Shift the gauge slightly to
8. Repeat steps 4 through 7 at the right end of the hammer bank.
9. After adjusting both sides, check the gap again at both ends. Readjust if necessary.

Printer setup

Continuous forms paper fed through the front of the printer also uses either the Front Push, Rear Pull, or Push-Pull tractor configurations. Make sure this is set correctly or it will reverse your margins.

It could also be your software. When you print through windows it's using the Microsoft system font controller, but your software could be setting font, margins, and alignment by the settings in the printer not in the driver. So if the first doesn't work, set your system back to align left then go into the printer configuration menu on the device and adjust the margins there.

Trying to use a jet direct box to make this a networked printer.

To "unlock" the operator panel on the IBM 6400 Line Matrix Printer, depress the Scroll Up and Scroll Down keys at the same time. On the IBM 6500 Line Matrix Printer, depress the Return and Enter keys at the same time.This acts as a toggle; if locked this action will unlock the panel, ifunlocked this action will lock the panel. The operator panel willindicate briefly which function is being performed. The printer powersup with the operator panel "locked."
