The SMK's have a percentage. When they reach 100, the printer complains, but can still be used. If the squeaking is your only problem, just replace the oiler felts. (I can do it in 10 minutes on the lower rail, for the ones on the upper rail, it takes longer and is mostly only done during the SMK3)

I have only installed fluo colors additionally to CMYK on sublimation systems. But the lightfastness is not very good.(to say it kindly) I know that swissQ has inks for their UV printers. Color vibrancy is a question of color management mostly, or dirty colors.(nice to see, how the changeover...

Hard to say from here. Often it's a PIP, or a (air)-leaking cartridge. Then it could be a pump, the tiny tube going to the pressure sensor. But the best one I had lately was a printmech board... it powered the primer solenoid all the time.

I just installed a S3 with camera last Friday. The mark recognition is really fast. (Compared to a standard Opos, or Graphtec, Mimaki, Roland) If you intend to do die cutting and have a decent Rip software, Summa is the way to go. This customer uses a somewhat clumsy workflow. Design and mark...

is it only at the first cut? Then it could be the damper inside the solenoid being compressed. This is a known problem in older Summas. The official solution is to replace the cutting head. I refurbished a couple of these heads successfully with new dampers.

Hello the creasing tool is just a pin with a radius at the tip. So it's omnidirectional. Real creasing wheels require tangential control. I've only seen them on Summa flatbeds, Kongsberg, Zund and the like.

2500.- sounds like one work day around here. During this time, it should be possible to create 4-6 printmode/media combinations. This depends of course on the printers functions... (a UV printer is more forgiving in terms of ink limit, than a ecosol or sublimation.) In my experience, defining a...

Sounds like a leak somewhere from damper to cartridge. Happened to me (mostly in the tubing)a couple of times with heavily used older machines like an EX now is...

The felts are presoaked,(I did many SMK3) The reservoir on the right isn't. For the felts on the back, they even include gloves, so you don't get the oil on your hands.

Look at the trailing cables(one for power, one for data) going to the print carriage. At a certain age (scan cycles), this cable starts to fray(if you see the shielding through the insulation, replace it)... inspect it.

Both printer-cutters can do that.

Is Skycut some Chinese copycat cutter? What software do you use? I had a case many years ago with a brand cutter, where I needed to decide if the curves are sent as short straight vectors or circle segments.(both is possible in HP-GL) If the software send straight vectors, how short do they need...

The lubricating felts are presoaked with oil. 3 in 1 is perfect.

Sometimes, the ink in the big cartridge and/or the intermediate tanks get demixed. Especially when your ink sat too long. I saw such issues after the COVID time. You can try to shake your inks. Sometimes we needed to replace them.

When I checked the installation document for the PC60 (predecessor of the PC600), it showed how to install the printer driver on Win3.1/95 and NT...

Well, it's either hours of your time to find some ancient software, that only runs on Win3.1 and takes hours to install ant train your customer, or you "donate" some cash to make it easier for everyone

Depending on what your "customers" intend to do with it, it's probably easier to buy a sign software(under 100 bucks), that supports generic Roland cutters or even HP-GL. I'd also interface it with a serial connection, but that's my take... I always connected the early cutters this way(35 years...

Maybe a distilled water flush, between the two cleaning solutions... There is always a risk, when doing such things.

Looks like your encoder strip is dirty. Check/clean it.

Read the manual and check out the Summa tube videos.
