Print quality and reliability
The drum unit (CF257A) is responsible for transferring the image onto the paper. A drum in good condition ensures an even printout free of shading and streaks. When the drum is worn, the page shows recurring spots, grey backgrounds or streaks — that’s when it’s time to replace the drum.
Replacing the drum unit
Open the printer’s cover, remove the old drum unit and take the new CF257A out of its packaging without touching the green light-sensitive surface. Fit the drum until it clicks into place and, if needed, reset the drum counter from the printer’s menu. Recycle the old drum.
When should the drum be replaced?
Replace the drum when the printer reports that the drum is running out, or when the printout shows recurring defects (spots, lines, a grey background) that don’t disappear after replacing the toner. The drum’s yield is up to 80000 pages.
