Model-specific reset guide
Epson CX3900 リセット廃インクカウンター
The service-required message on Epson CX3900 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.
Why Epson CX3900 stops printing
Waste ink produced by cleaning cycles is collected inside the printer. Epson CX3900 tracks those cycles electronically and can stop printing when the calculated limit is reached.
Wic Reset Connect is designed to reset the compatible counter in Epson CX3900. The physical waste ink system should still be inspected and maintained when necessary.

Epson CX3900 reset FAQ
What if the first reset attempt fails?
Correct the driver or USB communication problem first. If the key was consumed, use the new-key generator or contact support.
Does Epson CX3900 need service mode?
No. Epson printers do not use the Canon service-mode sequence. Connect the printer normally by USB.
Does the reset clean or replace the ink pads?
No. It changes the stored counter value. Inspect, clean or replace the physical waste ink system when its condition requires it.
