You need to replace the heater board. A SSR doesn't switch off anymore.

You don't need to go into service mode to backup the parameters. Just start it up and do a backup from cutter control. If not possible, write to summa. They should have the file somewhere. (These cutter can be over 20 years old...)

I had to replace hundreds of DX4 heads because of a 100% compatible ink, where the ink manufacturer (from the USA) gave a warranty on the heads. Not one was paid for... Since then, we sell only OEM.

First things first. A SP-540i is a CMYK printer. LC/LM/ and especially LK would help a lot, but not possible on this 4 channel printer. If your head alignment is off, you get grainy halftones, no matter the settings. A quick check is a 100/100/100/100 hairline (0.05mm) square 30x30mm or so...

Your problem is highly likely the cyan head, that needs replacement. The TR2 cyan seems to clog the head sometimes. Get it fixed during warranty.

Use the latest version of flexi, because there have been bugs in early versions of this bundle. If they don't let you update. Use the Summa plugin for Corel or Illustrator to create the marks, print it without any cut settings from flexi and output it with Winplot to the cutter. (You can find...

BN20 have been a pita since it was introduced... I told our sales guys to stay clear of them. Guess what, they sold a lot of this crap. BN2 are a lot better. (Choke valves in the ink path, Ethernet, instead of crappy USB, replaceable media guides, print heater and dryer... they actually fixed...

Your problem sounds like your orange is demixed. Orange is almost as bad as white, in terms of demixing.(if you don't shake the cartridges regularily, this will happen) There are alternative media libraries not using orange, but you need to activate them first, because they are hidden by default.

It's sort of masochism to run a old hardware with win/Intel drivers on a new fangled Arm Hardware on a Mac. We simply don't support it. If a customer has the time and nerve to try it, so be it. Just don't call me... My two cents to be constructive (after my rant), if possible try to use the...

Problem here is the type of printer. Since these are UV prints, they need to be cured and therefore need additional passes with the lamp. Ecosolvent Rolands would skip the white spaces.

Could be, that onyx only sends straight lines. I've seen other cutting software do this. This is not a big issue, when the vectors are sent to a cutter directly.

I have sold/serviced all major brands and never liked the complicated user interface of Graphtec. They cut nice, but the Summa (T) cuts superior and faster. I'd go for Summa.

HP has a automatic drop detector for defect nozzle replacement. Vanguard doesn't even have a manual way to do that. As long as there are no missing nozzles, it prints nice. But with degrading heads you will get banding. HP has a unique way of handling white with not much user intervention, where...

Sounds like the mainboard (formatter) needs to be replaced. There have been some small quirks in the early firmware versions, but not what you describe. Squeeking of the rewinder unwinder mechanics can be solved with a bit of grease most of the time.

There are different things, that can happen. The 315 doesn't have a spectro, so it measures the density with the line sensor. This is not very precise per se. The line sensor needs to be clean, otherwise it measures only bullsh... (the spectro sensor is closed/covered during printing, the line...

I'm pretty sure, you spilled ink over the feed encoder disk/sensor. (It's in that area in this printer) This needs to be cleaned/replaced.

I would not try it. What I can say for sure is, the printer will do a cleaning after every 30 carriage scans. (Not if you run it in service mode...) But, you don't know the chemical compatibility of the two inks. It could clog your heads instantly and permanently. To avoid this you would need to...

could be wrongly connected flat cables or bad head. (The bow in the magenta shouts: bad head)
