Why this answer matters
Faded output can be misdiagnosed when users treat 'toner' and 'drum' as the same part. Brother's standard-yield TN830 is rated up to about 1,200 pages under its stated method, while DR830 is a separate imaging drum.

Requirements
What has to be true
- Match the exact HL-L2405W model and regional supply family.
- Use TN830-series toner and the separate DR830 drum where those are the manufacturer-listed supplies for your market.
Verify it yourself
Use this test sequence
Change one variable at a time so you know which requirement made the difference.
- 1
Print a controlled grayscale/small-text reference before replacing parts.
- 2
Check the printer's toner/drum status and page counters where available.
- 3
If replacing toner does not change a repeatable print-quality defect, follow Brother's model-specific print-quality path before replacing the drum blindly.
Limits
What this answer does not prove
- Page yield is an ISO-based estimate, not a guarantee for every document mix.
- Consumable numbers can differ by region; imported units should be checked against their regional Brother support page.
