Similar to Tyler’s thread for the R1900, my R2400 has started behaving similarly. Today, for the first time, I installed the refillable cartridges I ordered a couple of months ago (with Cone Color K7 inks). Everything went well and I started printing some test pages for profiling the inks with Red River paper using SpyderPrint 4.2.3. The test pages printed perfectly. I then had to do some other tasks for a couple of hours and left the printer and computer on.
When I returned and continued printing the SpyderPrint test pages, the printer went into a cleaning cycle (a particularly long one in my opinion), then went through all the motions of printing (moving the paper into the printer, adjusting its position, etc.) then it stopped with the paper and ink lights flashing rapidly together (not alternately).
So I embarked on my 5 hour search through Google looking for an answer (like Tyler), and did all the obvious things like check for a paper jam, reset the ink pad counter using both the official Epson utlility (well, it wouldn’t reset anything because it said resetting wasn’t needed yet) and the SSC utility (which said the flashing lights was a “Fatal Error”), did a soft reset with SSC, removed all the cartridges and reseated them, and replaced all the cartridges with my second set of refillable cartridges. Nothing has worked - every time I try to print, whether it’s a page from SpyderPrint or an Epson head-test, it keeps doing the same thing as I described above (long cleaning cycle, bring paper into position, then stop with the two flashing lights). I’m really grateful I installed the waste ink bottle today because it is now more than half full! The only thing I haven’t done yet is put the Epson cartridges back in, but it’s now late and that will have to wait.
I’m guessing from Tyler’s post that you also don’t know what could be causing this to happen, but I thought it worth asking anyway.
