If you own a Samsung Xpress SL-M2165 or SL-M2168 monochrome laser printer, you’ve likely encountered a frustrating roadblock: the printer refuses to print, displays a “Replace toner” or “Toner exhausted” message even with a full cartridge, or—worst of all—shows a cryptic error code #676 on the screen or in Samsung’s Printer Status program.

This error is almost always firmware-related. Samsung (now owned by HP) aggressively pushed firmware updates designed to block non-genuine or refilled toner cartridges. The “676” error specifically indicates a firmware mismatch or chip authentication failure. Ultimate Guide: How to Fix Firmware, Chip Reset,

In this long-form guide, we will walk you through:

1. Understanding the 676 error.
2. How to identify your printer’s current firmware version.
3. The concept of “chip reset” vs. “firmware downgrade.”
4. Step-by-step instructions to fix firmware ML2165 ML2168 chip reset printer Samsung 676 link issues.
5. Where to find safe firmware files (the missing “link”).
6. Post-fix maintenance.

Step 4: Chip Reset – Manual or Automatic?

After downgrading, the printer no longer enforces the 676 block. However, the toner chip still shows “empty” if it was previously used. You now have two options: Understanding the 676 error

Option A – Automatic chip reset (preferred):

• With downgraded firmware, turn the printer on.
• Open the front cover, remove toner, close cover, open again, reinsert toner.
• The printer will reset the chip counter automatically. No external resetter needed.

Option B – External chip resetter:

• If the above fails, buy a universal Samsung chip resetter (e.g., “UniSmart” or “TNR-100”). Place the resetter pins on the chip contacts for 5 seconds.

Step 3: Downgrade the Firmware (Most Effective Fix)

Samsung/HP pushed firmware updates after 2018 that actively block third-party and refilled cartridges. The only reliable fix is to downgrade to an older firmware version that does not enforce chip lockdown.

⚠️ Warning: Downgrading firmware may void warranty (expired anyway for these models) and prevent future HP auto-updates. Step 4: Chip Reset – Manual or Automatic

Method 2: Firmware Fix (Permanent Software Reset)

This method modifies the printer's firmware so it no longer checks for the chip. This allows you to refill the toner indefinitely without buying new chips. Warning: This voids your warranty and carries a small risk of "bricking" the printer if done incorrectly.
