How to use

Before installation, power off the printer or follow the manufacturer’s guidance for hot-swap replacement if supported. Remove the empty or spent cartridge from the printer by opening the cartridge access panel and sliding the old cartridge out. Unpack the BLACKPOINT BLB3520BCBW cartridge, remove any protective covers or seals, and insert it into the cartridge bay until it clicks into place. Close the access panel and power on the printer if it was turned off. Perform a test print or alignment check if the printer prompts for it to ensure correct installation and print quality.

Usage recommendations

Store unused cartridges in a cool, dry place away from direct sunlight and high humidity. Use native or manufacturer-recommended print settings for monochrome output and select standard or draft modes for higher page yield when appropriate. Replace the cartridge when print density becomes uneven, faint, or when the printer indicates low toner. Recycle or dispose of the empty cartridge according to local regulations or take-back programs.
