T770 hangs at 58%

T770 44" hangs at 58%. I saw one other post for this. the solution appeared to be to "reseat" the formatter. Also, for the same post I saw the recommendation to pull ink and printheads and restart plotter and add one at a time to see whether one might be causing the problem.

 

I plan to:

1. clean formatter contacts and reseat the formatter later today and see what happens.

 

2. update firmware, if I can.

 

3. replace the hard drive if I have to--I'm not going to show up with a new hard drive today.

 

4. before hard drive replacement I may try to reset the EEROM--I don't even know if it's possible for this to rectify the problem.

 

Just my real quick thoughts, not sure I've thought through real well, heading to location this afternoon.

 

Thanks for any input.

Paul

Re: T770 hangs at 58%

I would check out page 55 and 56 in the service manual that is in regards to the LED's on the formatter card, which ones are lit, not lit, or flashing may help pinpoint you in the right direction.

OK, TJ, I'll check that out; saw that in manual but didn't think of it when I posted this. Thanks. I'm thinking a reseat will take care of this; I hope so.

Re: T770 hangs at 58%

I have it from a reputable source that the problem is a bad main pca--not the hard drive, so that's what I'll try. Reseating the formatter did nothing, still hung at 58%.

Re: T770 hangs at 58%

The main pca was bad. Replaced it and it was fine. For some reason, a few times afterwards, I got a 21.1:03 error having to do with the primer? pump. But after a few restarts it went away. Actually I shut it down, removed the ink cartridges, restarted it, and added the ink when prompted, then it didn't give the error again. Don't really know if there was any consequence to those steps or not.

Re: T770 hangs at 58%

Well dang, replaced the main pca now the customer says can't print anything to the plotter. Am I missing something? Thought all should've remained the same. Again, did have 21.1:03 error but don't think related. Maybe the formatter needs to be reseated? don't know.

Re: T770 hangs at 58%

Can you browse to its embedded web browser or ping it?  I hope it is just needing the connectivity info to be reprogrammed.

Re: T770 hangs at 58%

TJ, would it be normal to have to reprogram the connection settings in the front panel after main pca replacement? I mean the correct IP address was right there on the front panel upon "ready" status.

I'm away from the plotter right now.
