OK, I've got a CSDM72UVX at my new shop, and I'm trying to get it tuned up a bit, but having some issues. First all, I know it's a dog (according to MANY previous posts, and my own experience with it so far), but until I can get it replaced, I'd like to make it a well-behaved dog, or at least one that will stop pi$$ing all over the floor (metaphorically speaking). First I gave it a GOOD cleaning, which helped a bit, but then I ran into: Issue #1: the print heads are wildly out of register. Edges are fuzzy (Y-axis out of register), and there is serious striping (X-axis out of register). Diving into the manual, I decided to first run the automatic calibrations and see how much that helps... lord knows how long it's been since this poor old thing was calibrated last. I figured after that, I'd go through the (apparently tedious) process of manual calibration to further tune it up. Problem is, it's not completing the auto calibration. It prints the strip, thinks about it for a while, then says, "Automatic registration failed-- registration mark not found." Whiskey tango foxtrot!? Nowhere in the dox does it mention anything about this error, nor anything about reg marks in the calibration at all. I'm *pretty* sure I'm following the instructions correctly, but...? Issue #2: substrate (we run coro almost exclusively on this machine) warps & lifts off the deck after passing the platen, causing head strikes. Now, I did find a post on this forum about altering the UV lamp shutter angles, and I'm going to try this. I also made a weighted roller which holds the sheet down as it comes out. Definitely helps, but only once the sheet gets far enough to go under the roller. Any more ideas? Issue #3: STATIC!!! We've been using anti-stat spray, but that seems like a bit of a dodgy solution to me, and I'm skeptical about how it affects ink adhesion. Also, we go through those little spray cans like crazy. Gonna try to rig a dryer-sheet wipe behind the platen, but I also see in the dox mention of an "optional ionizer bar" (user manual, pg 3-25). Anyone have this? What is it, is it available, how can I get one, does it work, etc.? OK, I know this is a long post, but I'm hoping the wisdom of the forum will prevail and send me some good ideas to try. Issue #1 is my top priority right now, since the rest matters little if the print quality isn't there. Yeah, I know it's never gonna be a LightJet, but I'd like to see a lot LESS of the banding and edge-fuzzies. And again, I know this machine's best use may be as an underwater habitat for marine life, but until I get the machine I want, I'm stuck with the one I've got. Love the one you're with, right? Cheers all, looking forward to the responses.
