爱普生 WorkForce 840 重置废墨计数器
The service-required message on Epson WorkForce 840 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 WorkForce 840 service message means
Every cleaning cycle sends a small amount of ink to the waste ink system. Epson WorkForce 840 adds that activity to its counter and displays a maintenance warning when the programmed threshold is reached.
Wic Reset Connect is designed to reset the compatible counter in Epson WorkForce 840. The physical waste ink system should still be inspected and maintained when necessary.
