Well... it's gone midnight here now, but I just got back home after 4 hours at the unit... Damper deflating now I managed to get into INK FILL (air pg)... Checked ink lines as didn't see much coming out, just a bit of the flushing solution I left in the heads and nothing more..... More damper...

Absolutely, but 90% of the magic is the same, just different parts are moving! The fact is my friends still need flatbed for sample printing etc, colour management testing anyway and the overlap is significant. The ink management, heads, driving electronics are some of the more interesting...

I wonder how hard it would be to drive a number of heads that could put down a solid opaque white base coat in a single pass conveyor system, LED UV cured, compatible to be overprinted by CMYK inkjet next down the line (Agfa design PID or DP ink set)... Friends of mine been quoted almost $80K...

I'd hope to be able to modify this one to be able to take bottles, perhaps through tweaked old ink cartridges, assuming it all gets back to action! Now for today's update... Finished cleaning of the station assembly and fitting of newly serviced pump heads, the glued capping top plate is...

Thanks, I found the removal quite awkward, as that rear tab prevents a 'straight up and out' approach which would have been nice. The service manual (calling them dumpers ?!) doesn't particularly say anything special that I saw about reinstallation other than being the reversal of removal...

The pumps ready to go back in the station housing. The worst of the ink mess that was basically EVERYWHERE under the station was cleaned up (the felt pad removed, clearly totally full as it weighed a lot!) Could do with an Ethyl Acetate pressure washer :) That chemical certainly makes...

Dampers and belt have arrived! However before the exciting and highly anticipatory printing test can be done (Schrodingers cat anyone, the heads are both dead and alive until observed!), the repairs to the peristaltic pumps is needed and a bit more clean-up in that area first. I think we may...

Getting the pump head plate assembly out wasn't particularly easy, the capping section had to be unscrewed to make it easier (had to come apart anyway for cleaning) Separated the pump heads, and flushed through the peristaltic tube sections with ethyl acetate just to clean up a bit so don't...

This evening was a bit more cleaning ready for the pump repair (waiting on the replacement tube hopefully tomorrow) My hands have been a bit of a pain recently, I think down to sweating in nitrile gloves for 2-3 hours (not contact with ink), developed an itchy nobbly rash, so trying to limit...

Thanks! It's quite a journey, but hopefully will be of help to someone else too. Thanks for the information on the butyl carbitol, seems we can get this as Butyl Diglycol here in the UK. I wonder if that's what is used in the 'flushing/storing' agents with a slight oily consistency. I guess I...

Solder bridged the gap on the first repair... Covered with a UV cured conformal coating and additionally hot melt glue to both sides of the cable for additional mechanical support. The second cable repair wasn't so easy, as unfortunately the gap was a little large for solder, so had to use...

Two of the head EVEN/ODD connectors were then swapped around and the HD THERMIST error moved with the head cable, so it wasn't a fault with the slider PCB. It was felt to be a bit odd to have two even channels with the same failure and I'd understood these heads to be very reliable/durable, so...

Slider relay PCB with FFC cables to slider board disconnected, showing no D1 light (located between CN3 and CN7): Inspected the board for fuse problems etc but found nothing obvious, all fuses intact (the fuse for the 'D1' led power indication is on the reverse of the board). I started...

Hi everyone I thought it may be helpful to someone if I'd document/share my experience of bringing back to life an old UJF-3042 printer, purchased with the aim of helping out a local business print product samples and experiment getting colour matching right (printing on various plastic...
