Installation & Troubleshooting

Installing: open the printer's front cover and remove the toner cartridge if it sits in the drum. Pull the used drum unit out by its handle. Unpack the new drum in dim light, remove the protective sheet or packing pins, and never touch the green drum surface. Slide the drum in until it locks, reinstall the toner cartridge and close the cover. Reset the drum counter if the printer asks.

Drum messages: if the printer still reports a worn drum after installation, reset the drum counter from the printer's maintenance menu (see your printer manual). If it isn't recognized, check that all packing material is off and reseat it firmly.

Repeating marks or light print: make sure the protective sheet is removed and the toner cartridge is seated in the drum, then print a few pages to settle the toner.

Compatible vs. Remanufactured vs. Original

Original (OEM) supplies are new from the printer brand and cost the most. Compatible supplies, like this one, are newly manufactured by a third party to the original's size and page-yield specifications, so they drop into the same slot at a much lower price. Remanufactured supplies are emptied originals that have been cleaned and refilled.

Frequently Asked Questions

How many pages does the Xerox 101R203 print?

About 10,000 pages, based on Xerox's rating for the original 101R203 at roughly 5% coverage.

Which printers does it fit?

WorkCentre Pro 635, WorkCentre Pro 645 and WorkCentre Pro 657. See the full list above, or check our Find Ink by Printer page.

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 it sealed in its light-proof bag, away from heat and sunlight; a drum unit can be damaged by light exposure.

When will my order ship?

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