6. What is the difference between toner cartridge and drum unit?

There are many brands who produce integrated ink and toner cartridges. But not Brother brand. You must purchase both toner cartridges and drum units to install them in your printer together. One the one hand, the toner cartridge contains toner used to create crisp and clear text and image. On the other hand, the drum unit transfers the toner to the paper.

7. When does Brother toner for MFC-L3770CDW expire?

The shelf life of the Brother MFC-L3770CDW toner compatible is 2 years from the date of manufacture posted on the cartridge box.

8. Do these toners dry up if not used often?

Toner is supposed to be dry. Because it is a powder, not a liquid like the ink. Just make sure you do not store it in an extremely humid environment. Because if it is wet, the powder may gather together. Thus, your printed documents may have all kinds of issues.

9. What may caused faded blue stripe on the edge of my printed document?

Streaks on copies and prints can be caused by contamination in the paper path, such as contamination, dirt, or debris on the print head lens or conveyor belt. Such defects may also be caused by the use of wet paper or the use of paper that does not meet the correct specifications of the machine.

10. What is the chip on Brother MFC-L3770CDW series toner for?

There are two reasons why original brands install chips. The first is the original brand want printer users to purchase the original Brother product only. For customers, on the other side, when you can buy a third-party compatible toner cartridge at a very low price, this chip will make compatible brand developers spend much more time studying the chip. And the price of cartridge replacement will increase for the research and development costs and time they pay. The second is the printer can track the amount of toner in multiple cartridges.

11. Will TN227BK runs out after it prints 3,000 pages?

Yes, in the first place, you can expect about 3,000 pages at a coverage of 5%, which usually means a black text without rich images or graphics. It might run out faster if the coverage is over 5%. On the contrary, it will last longer when the coverage is less than 5%.

Moreover, when the printer displays a low toner message, you can take out the TN227BK toner and shake it from side to side several times. Then, put it back into the printer. By doing so, usually it will print more pages as expected. If the print quality starts to decline, it's time to replace a new toner.

12. What is the difference between high-yield toner and standard-yield toner?

The sole difference between Brother high capacity toner and standard capacity toner is that high yield TN227BK can provide 3,000 pages on A4 paper. In the meantime, the standard yield TN223BK will provide 1,400 pages on A4 paper.
