Digital BW, The Print

A little entertainment for you guys at my own expense.
Today I finished running curves for both a 1400 and a 3800 and decided to run some prints, compare the two printers with their different carbon ink sets and in general, just play a little.
But, I decided to first fill up all the cartridges. The 3800 in particular drank buckets of ink just getting the old ink out and the new ink in.
All set, start with an old image that needs to be reprinted anyway and run some tests. Nozzle check on the 1400 shows blocked Ebony. Expected, played with that quite a while and it was just plain stubborn. So I decided to make a BO print, thinking that would clear it out.
The BO print looked pretty good so I decided to make a print with all the grays (4). It looked like hell!
Tried to make a toned print. (I have magenta and yellow inks in the two leftover channels for separate curve toning.)
It looked horrible. Magenta everywhere it shouldn't be and quite noticeable despite a very small percentage of toner set.
Went back to try to make a straight 4 ink B&W print without any toner and was horrified to see magenta all over it. (Have you guessed yet?)
Started to wonder if my relatively new printer had somehow blown a gasket when, looking a little closer I realized that when I had reinstalled the cartridges after filling them, I accidentally swapped out the M ink cartridge with the one holding LK ink!
Here's the weird thing. Two cartridges were in the wrong slots and the 1400 didn't notice or care. Apparently those aftermarket chips don't tell the printer which cartridges they are supposed to be!

Anyway, when you stop laughing...!
