If you’re shipping a legitimate installer helper, follow these best practices so users and admins can quickly validate it:
Follow these investigation steps to establish provenance and behavior:
When executed (often requiring disabling antivirus and entering “Service Mode” on the printer via button sequences): adjprog l4150 l4160exe
The software allows for varied cleaning levels (Initial, Standard, and Deep) that are more granular than the standard user-accessible cleaning functions found in the driver. The "Ink Charge" function is used specifically when installing a new print head or after replacing the main board, drawing ink through the system to prime the nozzles.
Epson’s L4150 and L4160 printers are popular consumer-grade ink tank systems. Like all inkjet printers, they maintain an internal waste ink counter. When this counter reaches a hardware-defined limit, the printer locks operation, displaying “Service Required” or “Parts end of life.” Authorized service centers use proprietary Adjustment Program (adjprog) software to reset this counter. However, leaked versions circulate online under names like adjprog l4150 l4160exe. If you’re shipping a legitimate installer helper, follow
This paper dissects the nature of such executables, their operational mechanics, and the dangers of running unsigned service tools.
Most shared versions require a key. Common keys for L4150/L4160 versions include: The software allows for varied cleaning levels (Initial,
Before resorting to a risky executable, consider these safe alternatives:
| Error / Behavior | Likely Cause | Action | |----------------|--------------|--------| | “Communication error” | USB driver not in Epson “MFP Basic Mode” | Reinstall printer driver in single-function mode. | | “Model mismatch” | Wrong .exe for your printer | Use L4150.exe for L4150, L4160.exe for L4160. | | adjprog crashes on launch | Missing VC++ redist or Windows 10/11 compatibility | Set .exe to Windows 7 compatibility mode + Run as Admin. | | Counter does not reset | EEPROM protected / tool version too old | Locate newer adjprog version (e.g., v1.1.0+ for L4160). |
