OK, so label me dumb. I reconnected the trailing cable to the carriage assembly and the electronics panel, etc. and began the startup test.

 

I haven't done anything with this model before, so in reconnecting the trailing cable, I damaged one end of a connector (they're fragile). Yes, now I know. The damage can't be repaired (they are REALLY fragile).

 

So, I've ordered a new trailing connector - and we'll have to wait a bit to see what the start up test tells me.

 

Thanks for your patience. I'll be back.

I hope you did not start up the plotter with the damaged cable. If you did you may have blown the emod. You have to be very careful when installing the new trailing cable at both ends. If the cable is not installed correctly you can blow the emod and they are expensive and hard to come by. The hardest part in installing the cable is at the emod location since most emods have a big bracket that each cable goes into and sometimes when they are inserted they do not fully seat. I usually recommend removing those brackets so you are only left with the little black connector for each cable since it is easy to tell if the connection is fully seated and not at an angle. Many years ago I blew an emod and ever since I always remove those brackets. If you are lucky then you will see a small glass fuse at the top above the trailing cable. Some later model non plus models came with the fuse rather then a square testing point which is 10A and if you have the fuse then that will blow if the cable is not seated correctly and that fuse is replaceable which makes life a lot easier.

New drive belt and trailer cable arrived today. Installed both.

 

The trailing cable is a royal pain to thread and fold properly - as if I don't need to tell you that.

 

All that being said, I continue to get a trailing cable error on the self test.

 

I pulled both ends of the trailing cable and reseated them - taking extra care. Same error.

 

Suggestions?

As I said if the printer was powered on with the cable not sitting right or damaged, then odds are the main board has been blown. There are a number of surface fuses on the board that blow and the only way to repair to to solder new fuses. If the board had the little fuse I told you about in my previous post above the trailing cable connectors, then you just need to replace that one fuse which is a snap in type.

Main board is the older type with the the non-replacable fuse. I have one more thing to try, then we'll see.

 

As I do the self test, it starts OK, begins to cycle, then I give a quick "close right door" followed by the trailing cable error code.

 

So - what's a new or replacement board cost?

Big bucks. Do a search on this site as there was a person named Ralph McGranahan <rmbservices@sbcglobal.net> He repairs the boards. You could also try a google search of his name and hp designjet and CAL which is where he is located.
