ABSTRACT:
A remanufactured laser printer toner cartridge having a foam gasket seal with the transverse edge of the inner periphery extending from a longitudinal edge at an acute angle, preferably about 22 degrees, which angled edge prevents post testing excess toner from building up into a roll and jamming at the exit port as the remanufactured cartridge's pull strip is pulled when making the cartridge ready to install into the printer, and minimizes the likelihood that the gasket will be pulled off of the cartridge hopper section and jam the pull seal exit port as the pull seal is removed from the cartridge.
