Frequently Asked Questions

Do I have to install a new toner cartridge into the Lexmark T640DTN when the toner level runs low?

Not necessarily. You can still maximize the remaining toner inside the cartridge by redistributing it. To do this, simply remove the cartridge from the T640DTN, shake it a few times, and reinstall it. You can print a few more pages with improved quality after doing this. But consider getting a replacement toner cartridge because the old cartridge will not last that long.
