Does anybody know anything about the code to replace the ink supply station update there was no paperwork in the box on how to put the updated part in and update the firmware?

Hey Mike,
Found this info on the PartsNow site.

HP DesignJet’s New Ink Supply Station:
How to fit a square peg into a round hole
by Steve Geishirt, Director of Training
and Cesar Jump, Customer Support Technician


When HP improved its Ink Supply Station (ISS), they forgot to mention that the new part looks nothing like the original! Now it’s like fitting a square peg into a round hole. Parts Now! will give you tips on how to replace the Designjet 500’s ISS without losing your marbles!

More service techs are servicing the HP Designjet series – that’s because the series is a great revenue opportunity. After all, if a customer spends $5,000 to $30,000 on the large format unit, they won’t hesitate to pay for a service call. But there’s a new issue facing these service techs:an upgraded ISS station for the Designjet 500 & 800 series is creating a lot of headaches. The instructions to install the new and improved part are incomplete and worse, no service notes exist even for those who are HP authorized. The result is an incomplete repair: the fix for one problem automatically creates a second problem.

Three conditions exist when this problem occurs. A “maintenance due” or “all the ink cartridges displays a “X” message will require that you replace the Ink Supply Station; a 22:10 error code mean the spittoon is full and the ISS must be replaced. The new part number for the Ink Supply Station is C7769-60373. The replacement looks completely different from the original, (Figure 1). It’s not going to fit the same way the old one did. This usually spurs the first call to Tech Support: “Did I get the right part?” The answer is yes, so now the technician installs it, only to find a new message: “ink cartridge replacement required” for all inks. But even when new inks are put in, the message persists. Time for the second call to Tech Support.

What’s going on here is the new ISS no longer needs the spittoon (bottom black catch tray, Figure 3). However the instructions don’t say that. If techs install the new ISS according to the instructions in the service manual, the incorrect fit ends up pinching components on the new ISS. The pinched component is the cam system that is used to prime the cartridges.

There are “bongos” (Figure 4) – yes, it’s the technical term – that work with the cams (Figure 5) to raise and lower the bongos in the ISS station. This raising and lowering acts like a pump, increasing the air pressure in the ink tank or ink cartridge. The ink in the cartridge is in a bag, thus as the air pressure around it is increased, the bag of ink is squeezed which forces ink into the tubes which feeds the print heads – the crane assembly. If the bongos are inactive, there is no pressure to force out the ink. This lack of ink flow leads to an error code that there is an ink out situation. Oddly enough, when the cams that activate the bongos don’t turn, there is no error code, even though there is a sensor that monitors it.

The solution is two-fold. 1) We need to remove the old spittoon, black bracket in the back of the printer and discard it. It is no longer needed on the new ISS station. The old ISS station tended to leak ink which is why this spittoon was there. The new station fixes these issues. Removing the spittoon is only the first step. 2) An error 22:10” or in some cases the “Ink Cartridge Replacement Required” pops up after removing the spittoon. There was an Aerosol/Fan on the a servicestation and it is now gone and no longer needed. The old firmware is looking for the Aerosol/Fan. Upgrading the firmware before you remove the spittoon is vital.

Procedure for the Removal of Ink Supply Station Upgrade the firmware first. Before you start working on this printer, you must have the latest version of firmware, higher than A.02.14. If not, you expect some ink to leak!

Remove the right Cover Assembly, there are 5, T20 screws. Next, there are two ways of unlocking the carriage assembly. The first way is through the menus (Option 1 below). However, if the printer is in error state 22:10, or Ink Cartridge Replacement Required, then you cannot access the Service Menus so you will need to choose Option 2 above, right.

Option 1: 1.Go through the Set-up Menu.

2. Once inside the Set-up Menu, press the following key combinations to access the special service menus.

3. Press the UP and ENTER keys together at the same time to access the complete list of service tests (press for no longer than 3 seconds or until Initializing begins.

4.Once inside the Service Tools menu, press the UP or DOWN key until the front panel displays Service Utilities. Then press ENTER to access the Service Tools. Once inside the Service Tools, go through the Service Utilities.

5. Select the UP and DOWN arrow keys to highlight the “Unlock the Carriage.” Then press the ENTER key to begin the work.

6. Once this is completed, you should be able to slide the Carriage Assembly to the right and move it out of the way.

7. Now you can remove the Ink Supply Station.

Option 2:

2. Go through manually by turning the white gear (Figure 8) right under the one white spike gear, and then do 4-turns counterclockwise or until the black flag stops at a 45º angle.

1. Then move the Carriage to the right side of the Service Station and park it there. (Figure 8) This approach will reduce the repair time from days to hours.

Go to to this link, http://www.partsnow.com/service_today.asp. Once there, scroll down the page to the Resources, then click on the Service Today link. Once that page opens, scroll down some till you see a grid work of numbers, then click on the 11/08 link in the grid, it should open a PDF document for you that has the images included. Hope this helps. I haven't found anything about a firmware update yet though.
