    Designjet 510, broken latch

    Customer broke again the latch and also the ink tube cover for the 2nd time within 6 months. I replaced last December both the complete Ink Tube system including cover and also the purple latch with original HP parts.

    Question: What could be the reason other than customer induced damage caused by bare stupidity? Got replacement for the broken parts thru eBay but would like to know what's behind it that those parts became damaged again so soon.

      I've only seen one latch broken, and it was not one of my smarter endusers. =^..^=
      If you'd like a serious answer to your request:
      1) demonstrate that you've read the manual
      2) demonstrate that you made some attempt to fix it.
      3) if you're going to ask about jams include the jam code.
      4) if you're going to ask about an error code include the error code.
      5) You are the person onsite. Only you can make observations.

          If they leave that purple latch out (unlatched) and close the cover, the carriage bangs it into the arch on the right and then shows an error that the carriage latch is open. I think this is what breaks the latch, but it's just a guess.

          The printer will work without the latch or the top of the carriage latched down.

              seeing how this is the 2nd latch/tube set, clearly the end user is not performing replacement correctly..

              Agree with Kiran ... I would not warranty/call back on this.. this should be a CHARGE call...

              review the procedure AGAIN with them....

                  Thanks guys.

                  Another question came up. The purple hub of the paper roll spindle is cracked. Can this be purchased separately? # please?

                      HP only supplies that part as part of the entire spindle assembly. 24" is C7770-60094 the 42" is C7770-60005. LPS has them for $66 and $80, respectively.

                      Or you can usually find just the blue collet on ebay.

                          Don't want to open a new thread since its the same machine and customer:

                          A few days ago I've replaced the above mentioned latch/ink tube cover. The customer informed me during that occasion that the machine sometimes makes magenta colored blobs on the paper. Pictures attached.

                          There seems to have happened a spill of ink where the ink tubes enters the printhead. Since the machine was operating well for the moment I didn't want to inspect the cause or do anything cause the customer is heavily depending 24/7 on this printer. Could it be such an easy thing that the ink tube slipped from the nipple or may I expect that the recently replaced ink tube assembly got damaged by the previous broken latch issue?

                          Thanks

                              The tube assembly is broken and should be replaced. This is also the only way to correctly repair the carriage cover latch.

                                  My guess is that in the process of installing, you accidentally fractured the barb where the tubes join the carriage. It's easy to do.

                                  If you still have the other ink tube assy maybe you can cobble something together from the collection of parts. =^..^=

                                      Definitely NOT!! (Cat, you are the only one I would allow such a remark about me, but you're wrong this time. lol )

                                      This happened long time after I installed the ink tube assembly and before I installed the ink tube cover. In the mean time however, the notorious nervous customer managed to break the latch and the ink tube cover.

                                          Guys is this the part which is broken:

                                          Dusenanschluss fur HP DesignJet 500 510 800 Tintenschlauch C7770-60286 | eBay

                                          Or do I have to replace the whole ink tube assembly #C7770-60286 again? *

                                          Thanks

                                              You can certainly try that, but in my opinion I would only replace the entire tube assembly and not try to repair the assembly yourself.

                                              The tubes are meant for that barbed fitting to go in once. If you can even manage to pull the old one out, I wouldn't expect it to seal correctly on the replacement barb. You really need to cut the used end of the tube off, and I doubt there's enough slack to do so.

                                                  Kiran is correct on this. I've tried it. I ended up having to cut off the tubes from the barb as close as possible (was flushing the ink out of the tubes) and then put the tubes back on the barb with use of a hair dryer to warm up the tubes. They slid on okay but there's not enough slack to let the tubes rest in the proper seated position and get the cover to stay. Replacement is the best way if it's for a customer. If it was just my personal printer I wouldn't have a problem with it.

                                                  If I was to do a flush job again, I'd take the tubes off the ink station end instead. Plenty of slack up there.

                                                      Thanks guys.

                                                      Are those 4 tubes fused together or are the separately lying in the tube holder assembly? Or asked the other way around: Would it be possible to move one tube downwards a little taken advantage of the slack at the ink station?

                                                      When an ink tube has been removed from the head, is it than necessary to prime the system again?

                                                      'told you I'm a noob.......

                                                          If you fool around with the tube (cutting pieces and refitting and replacing parts) you'll have to suck the air out. Parts of the tubes are together. I'm not sure where though. I wouldn't mess with it. It sounds like a good way for a customer to come back and claim you stained their rug by making ink leak all over. I would just replace the ink tube assembly.
