Before learning how to use the adjustment program, you need to understand why your SX 125 stopped working. Common symptoms include:
The cause is the waste ink pad counter. Every time your printer cleans its nozzles, a small amount of ink is dumped into an absorbent pad inside the machine. Epson sets a hard limit (usually around 15,000 to 20,000 cleaning cycles). Once reached, the printer stops working to prevent ink from spilling inside your home or office.
When the adjustment program does not work, you will see an error code. Here is what they mean for the SX125.
| Error Code | Meaning | Solution | | :--- | :--- | :--- | | Communication Error 20000010 | Printer not in maintenance mode | Repeat the button combination exactly. The SX125 is picky with timing. | | Function not supported | Wrong program version | You need the SX120 series program. SX130-only versions will fail. | | Timeout error | USB buffer issue | Disable "USB Selective Suspend" in Windows Power Options. | | Counter reset failed | EEPROM write protection | Power cycle and retry. If persists, the EEPROM chip may be physically failing. | | 20000100 | Printer is still in busy state | Unplug all USB devices except the printer. Reboot PC. | epson adjustment program sx 125 work
In the menu that appears, select:
Here is where most online guides lie to you. The adjustment program resets the counter, but it does not empty the physical sponge.
On an SX125, the waste ink pad is located at the bottom right side of the printer (under the capping station). When you run 200+ cleaning cycles, that sponge becomes saturated. Before learning how to use the adjustment program,
If you reset the counter without cleaning the pad:
| Problem | Solution | |---------|----------| | “Communication error” | USB only; disable firewall temporarily; reinstall printer driver first | | Program doesn’t open | Run as Admin + Windows 7 compatibility mode | | “Check model name” | Wrong region firmware – try TX125 / TX420W version | | Reset says “OK” but error returns | You need to physically clean pads first | | Printer still shows error after reset | Turn printer OFF for 30 seconds, then ON |
If you have decided to proceed with using the Adjustment Program to reset the waste ink counter, follow these steps carefully. The cause is the waste ink pad counter
Ensure your Epson SX125 is connected to your computer via USB and powered on. Make sure there are no paper jams and that the printer is in a ready state (aside from the error lights).
Epson does not officially support the use of this program for end-users. Using it voids your warranty (if still valid). However, for an older model like the SX 125 (discontinued in most markets), the adjustment program is often the only way to keep a functional printer out of a landfill. Many repair technicians use it daily.
