Looking for folks who are using the latest firmware update PLS_32_22_23.7 in their 800w machines. Was anything broken in this revision? Just curious as my last update killed the media advance. Thanks all
Narrowed down for this media DreamScape Caviar with bad coating (lines in the coating transmitting right through the ink). 4 rolls in the same lot # with other perfectly fine rolls.
We have the sane thing happening with our 360 using a variety of media. I believe its from the heater elements needing replacing. we just took apart the heater box and unplugged all the small holes which were filled with latex ink dust. That helped but did not eliminate the issue. I have a tech...
FWIW
Open bed UV Flatbed printers create an huge invisible cloud of micro droplets as they work. They permeate the air and land on everything in the vicinity. Becoming sensitized to these or other chemicals by contact or inhalation is not uncommon globally.

Tension is set to 8 but HP is adamant to not increase the tension saying that tension is like pulling the media along. Waiting to hear back. many prints were already produced just fine, its just happening with a heavy ink load across the print area
So I have been printing a job on the 60" version of this material in 8 pass 110% ink-vacuum @50 and have had the ink scraping the leading upper edge of the curing unit. Hp said to lower the curing temp from 195 to 180 which helped until I got to a dark section with full ink load.
Does anyone run...
just to follow up, replaced Y/M head after shaking up the ink box and sub tank. Two hard cleanings and voila, full strength yellow ( not quite as instantaneous as voila )
I do know this is not an isolated issue. Two 800w machines banding as described, bought to run in 6 pass as advertised in Virginia. Final solution unknown, that was 1 month ago.
Nice schematic, called up tech support after shutting down machine, said to just pop out the sub tank and stir it up. Restart and do a couple of hard cleanings to clear the line. Am ordering a fresh box of yellow and replacing the head. Thanks for your input, much appreciated!
yellow water is right, so I have the access to the sub tanks open but I'm not sure what air line I'm looking for. Can you remove the sub cart with the machine powered on?
The machine had sat idle for a couple weeks (at least), yellow nozzles are all firing when viewed via blue light. Color cal was run with image quality being identical before/after. I’ll switch profiles at the rip and maybe run a pure yellow stripe to get ink moving. I can move the Y ink box to...
I’m new to this machine, all nozzles are firing but the yellow is the weakest I have ever seen across many printers I’ve operated. Is this “normal” for this unit? Running front lit matte banner stock and Thrive 18. When I look at the profile color readings per color in onyx media manager, colors...
