You can get good reds on the HP as long as you have the right equipment ( spectro and software ) and 2 inch thick wood pulls through the 550 without issue. Setup time is 1.5 days for hardware, and training can go as little as another 1.5 days to 3 days depending on your current knowledge /...

Have you tried fine text mode? Dont think your overspray issue is a Black head anyways, looks like magenta to me. Small text with a composite black is a pain, change the text to a pure black on the rip and it will be better, fine text should make it crisp again.

Low suction on the belt is less likely due to ink on the belt ( unless the holes are actually filled in with ink ) and more likely to be fouled vacuum blower fans inside the belt drive assembly. For the HP/ColorSpan type flatbeds, these trays can be pulled out and cleaned, or replaced in the...

The best flatbed techs in your area are Sonoma Graphics. Not many independents out there on the HP flatbeds aside from myself, and I am outside of driving range to you.

I bet it's not a printhead... I bet you have either never changed, or forgot about changing the lens that covers the color sensor on the carriage. If there is a block of black foam inside the cover over the print zone, you should find a few replacement lenses in little plastic bags. Dig...

Do not use a razor or any other blade to remove ink buildup. I have replaced several belts because the operator slipped and damaged the belt. Because the belt is under tension, small rips grow into tears, and a torn belt can lead to huge problems. Add a headstrike event and you can destroy every...

that reseat printhead error can be as simple as a bad printhead, but it can also be a bad interconnect board, or a data cable. Assuming you are looking at a used unit with no service contract the repairs could cost you.. Try a fresh printhead in the unit, if that does not clear the error I...

like I said, it will work, but when the internal wires fail you will get opens, or shorts. If the shorts invole the 4 wires that are normally not connected it CAN damage one or both boards depending on how the cable fails. Just because a workaround does work, it does not mean that it is a long...

you will get punchier reds and blues running a CMYK profile vs a CMYKcm profile. Onyx default rendering intent is usually set to "perceptual" but for vector color work you will see brighter colors with a "saturation" setting. If your red is too orange, pull the yellow back 10 or 15%, and add a...

respectfully going to dissagree with Wunder. The LVDS cable is a straight through cable, but it only makes use of 4 wires AND the RJ45 connectors are grounded to the cables sheilding, ( So it IS NOT a standard LAN cable ) while you can run for a brief period with a 8 wire cable, those boards are...

if you are still having this problem the most likely culprit is a failing power cable to the headboard. The bundle of black and red cables carries several different voltages to the board, the printheads run from the 36v power supply, and if you get an intermittent open on that power line, there...

How much overprint are you running, and are you using "borderless sheet" on your Onyx? To hit a good full bleed on the 500/700 you do not need more than 1/8 inch overprint, unless your media is irregular. I see a lot of shops select the borderless sheet option in Onyx thinking that it sounds...

I bet you have "borderless sheet" set as your media type in Onyx, that will produce a -.2" margin at the printer. Change your rip to a regular sheet, and you can set your margins on the printer on the printing page, options menu.

regular profiling or color calibrations should get you pretty close color regardless of the RH changes. You should reprofile or at the very least recalibrate your profiles whenever there is a change in the environment, after you install a new ink, or replace any heads. The more stable your...

White underflood will get you the best color, and whatever you do... Do not run the job on MaxMetal. That stuff is coated with PVDF and you will not likely see good ink adhesion to it. Stick with polyester resin coated ACP ( DiBond, GraphicAL, etc ) for your flatbed printing, use the MaxMetal...

Technically, the LX600 uses 600 series inks, and the LX850 runs 610 series inks, so they are not the same, but you should see similar performance. I don't know how tight your heavy knit material is, but you will want to use the ink collector kit regardless of how tight you think it is. There...

if you are seeing 100% jetting, but you are still failing autojet calibration you probably need to clean your image sensor lens. I would reccommend powering the unit down, and removing the camera to clean it. You can used swabs with isopropyl alcohol, and an air gun to remove the ink and dust...

I doubt your ink was finished curing after 10 minutes, depending on coverage and density ( probably high in both cases due to printing on glass ) UV ink continues to cure at a molecular level for up to 48 hours depending on your ink and remaining life of your bulbs. You can get a better cure...

you should not be seeing that much ink on your drip tray, I would wager that you have an overfilled head or another vacuum problem. Is there ink in your vacuum tubes above the heads?
