The "top — long piece" in the context of the Epson L4260 Adjustment Program typically refers to one of two things, depending on exactly where you saw the phrase:

1. A specific check or wear counter – In some Epson adjustment programs, "Top Long Piece" might relate to a PF (Paper Feed) adjustment or a scanning unit component, specifically a long plastic guide or a timing scale strip (the transparent encoder strip). The program may ask you to check or replace it if it's damaged.

2. A mistranslation – Epson adjustment programs often have awkward English translations from Japanese. "Top — long piece" could mean:

   • Top margin adjustment (long paper) – i.e., adjusting the top print margin when using long paper (like panoramic or roll paper).
   • Long border top – related to borderless printing adjustment for long sheets.

Acceptance Criteria

• Successfully read and display current waste ink counter on L4260.
• Reset operation returns counter to zero and creates a verifiable backup.
• No change to unrelated settings unless explicitly chosen.
• All operations produce detailed logs and allow restore from backup.

Security & Safety

• Local-only operation warning (recommend offline use)
• Require user acknowledgment for irreversible actions
• Validate EEPROM/firmware files with checksums before apply

Step 2: Launch the Program

1. Right-click AdjProg.exe → Run as Administrator.
2. You will be prompted for a "Model Name." Do not type anything here if it is the "Top" version; it should auto-detect via USB.
3. Click "Particular adjustment mode" (This is the top option in the menu).
