"He who marches out of step hears another drum." ~ Ken Kesey
I don’t know anything about the Exile print heads, but if it’s anything like a Douthit and has only one print head, then it’s an easy replacement (as far as head replacements go). Similar to an Epson print head on an epson printer. Not that bad to do. For a single head, I dunno if it really needs a “calibration” as much as it does a proper procedure of bleeding the lines and doing a head clean/purge etc.I just did an install and training with Mark from Douthit and a separation customer of mine. The Douthit install/setup is easy. Most of his installs today, are done remotely. They ship it, you put it in place and log in with Mark and you set it up while he’s on the phone and computer. A head replacements might be the same in the Douthit case.A single print head on an I-Image takes a couple screws to remove, insert the new head that can only go in not slot and lock it in. Literally. That can be a 10 minute job. It’s only when you have more than one head on the I-Image where it gets more challenging. I’ve replaced 3 heads on an Image within 3 hrs including the calibrations after install.You just got that within a year didn’t you? Under warrenty?Is this the Vid you are referring to? There is no sound. I hate vids with no sound. But it doe look like you can handle this with no issues.https://youtu.be/Fn9wM-XhYVM
