    ICP challenge :)

    new install c6500 in the middle of setting it up, an ICP blew. i was in another state and it was already afternoon so i walked 8 blocks to a radio shack and bought this setup and soldered it in.
    i had someone hold my phone camera on zoom so i soldered the right points and i believe its still running to this day with a ,063A glass fuse.

    ran across the photo and wanted to share.

    anyone else have emergency copier surgery pics?
    We know a thing or two because we've seen a thing or two.
    The medication helps though...

      Great! Did similar in the past with a Di-450. But how did you find the location of that ICP? Metering out or do you have list with all the ICP's?

          That's got to be easier that soldering in a new ICP. I can solder to death (3), before a single one survives. Back in my Mita days I did something similar with backup batteries. Soldering a lithium battery directly to the board was tricky, but add a few inches of wire and it's manageable. Nobody was carrying a phone camera in 1990, lol, so no pictures. =^..^=
          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.

              Way to improvise! We use to do that a lot back in the day when machines were more mechanical & PWB's basic with componets spread apart. Today PWB componets are so small & close together that it's almost impossible to solder anything. The boards are "dipped" in a solder bath when made or done with robots. The soldering iron has been removed from my Platt toolcase for several years now. Still carry meter that I might use once or twice a year and same with vacuum in car. Lol this is how I'm downsizing getting near retirement Still way to many tools and stuff in my case that I never use!

                      Sharp had about 3" of wire on their replacement batteries. Plus they had empty spot on board where you soldered new batt in then remove the old batt. This way no counts were lost. Back in the day the OEM actually made some things easier, not many

                          yup, just got my needle probes and ohm'd a few before i found the bastard.
                          this sounds bad but when i found it i held a paperclip to both sides of the ICP and the machine didnt code out nor did the paperclip get hot on bootup so i was convinced a simple inline fuse would work.

                          We know a thing or two because we've seen a thing or two.
                          The medication helps though...

                              I've repaired many an ICP in the past using similar methods. On the latest machines though, it seems once the ICP blows, the component it's protecting is already blown as well.

                                  i dont recall the exact reason it happened however i would not rule out tech error

                                      no pics but i use the solid state icps that look like transistors , pre-form the legs to squeeze existing cube icp and solder one side at a time.
