Chips, Printer Messages & Installation

Installing: open the front cover and lift out the drum unit with the toner attached. Push down the green lock lever and lift the toner cartridge out of the old drum, then click it into the new drum until the lever lifts. Slide the corona wire tab back and forth a few times and reinstall the assembly.

Reset the drum counter: after installing a new drum, reset the drum counter from the printer's menu or by holding the Go/OK button with the front cover open (the exact steps vary by model). If you skip this, the "Replace Drum" message stays on.

Drum vs. toner: this is the drum only. It works with TN820, TN850, TN880 or TN890 toner and lasts through several toner cartridges.

Compatible vs. Original Drum Units

Original (OEM) drums are new from the printer brand and cost the most. Compatible drums, like this one, are newly manufactured by a third party to the original's size and page-life specifications, so they drop into the same slot at a much lower price. Castle Ink sells compatible (newly manufactured) toner and drums and remanufactured inkjet cartridges.

Frequently Asked Questions

How long does the DR820 last?

About 30,000 pages at one page per job, based on Brother's rating. Printing several pages per job extends it.

Is toner included?

No. This is the drum only; it holds a TN820, TN850, TN880 or TN890 toner cartridge.

Will this void my printer warranty?

No. Under the U.S. Magnuson-Moss Warranty Act, a manufacturer can't void your printer warranty just because you used a third-party or remanufactured supply. If a non-original supply directly caused damage, that specific repair might not be covered.

How long can I store it?

Keep the drum sealed in its light-proof bag at room temperature, away from direct sunlight, until you install it.

When will my order ship?

Orders placed by 4 PM ET, Monday through Friday, ship the same business day from Long Island, NY, by USPS (2–5 business days). Expedited 1–2 day delivery is available at checkout, and shipping is free on orders over $50.
