Fix Streaks on Lexmark C500

Step 6 Remove the blade

Under the carriage is a pair of plastic blades which feed the toner onto the roller and collect waste toner. The roller turns toward you, so the top blade is the one which causes the toner to be streaked. Grabbing the corners of the blade assembly, you can gently work it loose from its seat on the cartridge. There will be a lot of toner, so try to keep it from flying around too much.
