In August of 2017 I installed all nine new ink cartridges, with auto reset chips, into an Epson R3000. The ink levels showed as full on both the printer display and the laptop Epson printer status window. As I used the printer, the printer and driver both reported lowering ink levels and they both agreed with each other.
A few days ago the MK ink stopped working. Since the reported ink level showed just below 50%, I thought it may be clogged print heads. After running cleaning cycles, with no change, I pulled the ink cartridge out and found it empty. I checked all the other cartridges and they all had only about 25% ink remaining. Except yellow (Y), it was nearly empty.
Low ink level warnings were never generated for either the Y or MK cartridges. Only the PK cartridge gave me a warning. I don’t trust that the other cartridges will give me low ink level warnings.
Why are the cartridges not reporting proper ink levels and how do I correct the issues?
