Repair damaged circuitry to black ink cartridge

I have just aquired a 6940 printer. However, there is some damage to the ribbon circuit that feeds the black print cartridge. It appears that the metal spring holding the cartridge in place has become dislodged and has pierced the ribbon circuit breaking one of the tracks. I would like to know the best/easiest way of removing this part of the circuit so that I can make repairs to it.

    Thanks for the advice frcs68, however I have managed a repair. I was able to scrape away the top coating of the broken track thus exposing the circuit below, and using some fine copper wire and a very steady hand I was able to solder the wire across the break, and cover up the repair with some electrical tape. I was also able to do this with the ribbon still in the printer by just removing the housing for the cartridges. The printer is now working 100%

The ribbon i sprinted on a flex. it is non-repairable.
if you want. get some of the older ribbon (used for the IDE hard drive). but you need to unsolder the connecting connector and solder the ribbon directly to the ckt board. not a easy task, specially the components and feed through is getting smaller.

How do you get the ink cartridge out of the printer


  1. Unplug your Kodak Photo Dock's power cord. Pull the black tab on the right side of the printer down to open the ink cartridge door.
  2. 2 Push up on the green cartridge release tab in the upper center of the ink cartridge to release the old cartridge. Pull the old ink cartridge carefully from the Photo Dock.
  3. 3 Rotate the new ink cartridge's ribbon wheel on the side of the cartridge clockwise with your finger to remove any slack in the film. Do not rotate the wheel too much---this will damage the cartridge.
  4. 4 Insert the new ink cartridge into the Photo Dock with ribbon film facing down until you hear the cartridge click in place. The ink cartridge will only go in one way.



    Do not touch the ribbon with your fingers. Handle the cartridge by its edges.
  5. 5 Close the ink cartridge door and plug in your Kodak Photo Dock's power cord.
jQuery('.article ol .image').each(function(i,e){ var $this = jQuery(this); $this.find('img').error(function(){ jQuery(this).remove(); $this.remove(); }); });

The black ink cartridge has failed


It happens when that spring comes loose from the right side. When you get that hole, traces or wires in the ribbon cable are broken and you have to replace the entire carriage. Around $89.00

Printer not working


Hi I am Vortash either the printer circuit in the printer has a fault or the drivers have been corrupted or the control head is damaged or dirty .. So firstly remove the cartridge and with a small brush and some ink flush or alcahol gentley wash the cartridge holder check that the ribbon connecting it to the printer circuit is not damaged . Clean the print head ? cartridge connections with the fluid or alchahol and leave for five minutes replace and do a printer purge or clean . In add printers remove the printer that is installed and any secondry image drivers .. and rebbot the comuter follow the on screen instructions and install new drivers if you can update the latest drivers from the Epson web site then reboot again ... go to add and remove printers again and print test page or a document from your files .. if the fault has not ckeared the fault is the electronics of the printer and it will need an engineer to repair it .... Regards Vortash

The black is printing dark redish brown


Dear friend, your Black Ink Cartridge is Empty thats why your printer is using the Colour Cartridge to produce the Black Colour. This is the reason you are having Dark Reddish Brown colour instead of Black.

Printer Toolbox Not Recognizing New Black Ink Cartridge


Pop out the cartridge and look inside the printer where the black cartridge goes. There may be punctures in the ribbon cable from the metal wire that rests against the catridge. I have lost 2 6940's to this problem.
