The Epson PX-504A delivers reliable printing, but periodic maintenance routines can increase the waste ink counter and eventually trigger a ‘Service Required’ lock.

During head cleaning and maintenance cycles, excess ink is routed to internal absorber pads. The Epson PX-504A uses a software counter to estimate pad saturation and locks printing at a set threshold.

Most Epson PX-504A waste ink counter locks are solved by a software counter reset. Wic Reset Connect provides a straightforward procedure.

Common Symptoms

• Printer refuses to print even with ink available
