Expected page output and replacement cycles
Page yields for TN-2130 and TN-2150 Black toner cartridges are measured under ISO/IEC 19752 testing standards for monochrome laser printing. Actual page output depends on print density and document coverage.
| Cartridge Number | Type | Colour | Page Yield | Cost Per Page |
|---|---|---|---|---|
| TN-2130 | Standard | Black | 1,500 | $0.074 |
| TN-2150 | High Yield | Black | 2,600 | $0.055 |
Cost Per Page = Total Cartridge Price ÷ Page Yield (at 5% coverage). Prices based on Genuine cartridges.
Drum unit lifecycle and replacement
The DR-2125 drum unit is an independent imaging component that transfers toner onto the page and typically outlasts up to four standard TN-2130 toner replacements.
Choosing between genuine and compatible options

Pro Tip
Always keep a spare TN-2150 toner cartridge on hand, as laser printers halt monochrome printing operations immediately once the toner sensor detects a completely empty state.
Frequently Asked Questions
How do I know when to replace the DR-2125 drum unit versus the TN-2150 toner cartridge?
The TN-2150 supplies the black toner powder, while the DR-2125 transfers that toner to the paper. The printer displays separate warnings for toner depletion and drum life; drum units usually last through 3 to 4 toner cartridge changes before causing faint or streaked output.
Can I install a high-yield TN-2150 toner cartridge if my printer previously used a standard TN-2130?
Yes, the TN-2130 and TN-2150 share identical outer dimensions and slot directly into the same DR-2125 drum housing. The TN-2150 simply contains more toner powder, delivering up to 2,600 pages compared to 1,500 pages from the TN-2130.
Why does my Brother DCP-7040 still show a low toner error after installing a new cartridge?
This occurs when the mechanical reset lever on the toner cartridge does not fully engage with the printer's sensor during installation. Ensuring the cartridge is firmly locked into the DR-2125 drum assembly before sliding the unit into the printer usually resolves the issue.
