Yes, actually crossed them on the main board.  I've lost touch with the nomenclature.

Re: Important: Firmware upgrade for HP DJ T770/T1200

Hi Tim - just wanted to close the loop on my post. It was a broken starwheel assembly. We did replace it and although we had subsequent errors, they became moot after Budget office ok'd a new printer. Pity - I was hoping to troubleshoot it to the bitter end! Thanks for your help.

Thats good to know Sixhats, I've had times when I wanted to complete a repair like that and decisions were made to replace equipment instead, so you don't get the chance to learn in case you see the problem again. Please mark your post as solution resolved! Thanks.

Arekme, sorry so late.  I believe that white idler? gear that you are calling a bushing? comes with the star wheel motor.  If you still need it, I have 1--white gear that is slotted.  Think the starwheel motor came with 2 so have 1 left over.

Re: Important: Firmware upgrade for HP DJ T770/T1200

I have a T1200 with 22.0.10 code.  We have replaced the left ink supply station and the PCA board, but still cannot get the code to clear.  Any suggestions?

Hi, did you replace the starwheel motor and upon reconnecting main board cables possibly cross the 2 largest cables?  If so you need to uncross them and hopefully you didn't hurt anything.  If you did, and have troubles after uncrossing them, you might want to look at this thread:

The plotter had a 22.0.10 code when we were first called to service it.  We tried replacing the left ink supply station and that didn't take care of it.  We then replaced the Main PCA and the code still did not clear.  We never replaced the starwheel motor.

Re: Important: Firmware upgrade for HP DJ T770/T1200

Just in case:  for the 2 largest cables to the board, did you get the 1 with blue tape on it into the blue socket and the 1 remaining largest cable into the black? socket.  Think the 1 from the ink supply station goes to the black? socket.

 

If you swapped these 2 cables by chance on the main board, you would continue to get error 22.0:10.

 

I know you probably didn't do this (like I recently did), but just in case.

Re: Important: Firmware upgrade for HP DJ T770/T1200

Well, I assume you would continue to get error 22.0:10 if the cables were swapped.  I'm referencing a T770 not a T1200 on which I swapped the cables which could damage, in my case it did, the rewinder motor, I think, in the upper right roll support.  1 poster in the earlier thread link only had the motor bind up and freed it up and it no longer gave the 45.1:03 error - error related to rewinder motor.

We came in after another company was servicing.  I think we will check to make sure those cables are not crossed and see what we find.  Thank you very much.

Re: Important: Firmware upgrade for HP DJ T770/T1200

i remember its starwheel motor problem...


Try the following:
�� Switch the Power OFF from the back of the Printer and disconnect the
Power cord. Reconnect the power cord and power On the Printer.
�� Check that the Starwheel Assembly cable is not damaged and is correctly
connected to Main PCA.
�� Open the Window and check for any visible obstacles restricting the
movement of the Starwheel Assembly, then clear the obstruction.
�� Perform the Scan Axis Starwheel diagnostic test to troubleshoot the
problem further → Page 4-7.
�� Replace the Starwheel Motor → Page 8-167.
�� If the System Error continues, replace the Main PCA.
this is the definition from the service manual, hope this helps.

Re: Important: Firmware upgrade for HP DJ T770/T1200

If you have installed said upgrade you may find that you now have an issue with print orientation - specifically, A1 drawings will not print in landscape format on A0 sized paper. We have just solved this problem by installing the July 23rd 2012 firmware update (ver TT6-TTAJ_8.2.2.3. Why-oh-why aren't HP telling us that this update solves the ploblem?

In the netherlands you can buy the starwheel motor not directly from HP.

 

So we have placed the Starwheel motor Q6718-67017 in out webshop.
