Epson PX-504A Reset Waste Ink Counter
The service-required message on Epson PX-504A often relates to the internal waste ink counter rather than an empty cartridge or paper fault. The steps below help you confirm and resolve that condition.
What the Epson PX-504A service message means
Epson PX-504A uses stored counter data to estimate absorber usage. The estimate may reach its limit before the pads appear completely saturated, but physical maintenance should still be considered.
Wic Reset Connect is designed to reset the compatible counter in Epson PX-504A. The physical waste ink system should still be inspected and maintained when necessary.
