Thanks for answering, guys! :-)
In my P600 print dialog, I have an "expansion" option for borderless. This determines how much the print is enlarged beyond the edge of the paper. Where I have to go borderless (I try to avoid that as I don't think that the "spit pads" are user-replaceable), I see the expansion at minimum. This gives me a fine white line (less than a mm) around the edge of the print, giving me some confidence that overspray has been minimised. The thin edge is easily trimmed off. If you want to avoid trimming, you may be able to play with the expansion setting.
Good idea. I haven't touched the expansion setting so far.
The porous pads however, are easily replaceable. At least for the x900 series (haven't worked with others yet). They are just thin porous stripes of material, that are stuck into the holes and held by small "noses". The parts numbers are visible in the image I attached. They cost a few bucks but they are also easily cleaned with isopropyl acohol (which I am doing in a regular basis when I'm cleaning the wiper and the flush box).
But there lies the problem: With borderless printing, the overspray starts to saturate the pads up to the point where they act like a sponge. Any paper that touches them WILL get wet from the ink on the back side. Of course, the excess will get drained to the borderless maintenance tank at some point, but in my opinion, this will not stop the pad from acting like a sponge, just from overflowing.
My maintenance tanks are brand new and I can see cleaning fluid draining into the tank very well. It just seems like the porous pads itself are just not a really good solution if you do a bunch of borderless images in a row.
I will try the expansion setting first, if the problem persists, I guess roll printing is the solution.
Kind regards
