Question about Ricoh Aficio GX3050N Printer
I'm 99% all the responses on the error 990/999 are wrong. This error is due to a clogged waste ink line. These are great printers but they have some design weaknesses and this is one of them. I believe the waste ink coats the inside of the waste ink line and then a layer dries (the end of the waste ink line is open to the above the waste ink collector) then another, then another until the line clogs. You can put water inside the head cap when you have this error and the priming pump will not pull it thru to the printer and you'll notice no ink shows up in you waste ink collector. I was able to recover a GX3050sfn from this error by power cycling and chunks of dried ink showed up in the waste ink collector. Now the bad news, it does not seem to be simple task to clear the waste ink line, but I'm working on a solution. I've tried connecting an extension tube to the waste ink tube above the collector and pulled a vacuum with a 60mL syringe when the printer was powered on but no luck (this can clear epson waste ink line clogs because I've done that many times to fix C80s/C84s/C86s etc.). It is possible to prevent this from ever happening by creating a sealed bottled waste ink system (contact me at email@example.com if you want help with this). I should have a fix also very soon even if I have to disassemble the printer.
