Break the tab and pull out the tape and print again. The sticky tape is seal of the toner tank.

The seal tape might be inside the cartridge, attached to a pull-tab.

I am only specifically familiar with the HP toner cartridges, which have a colored plastic pull-tab attached to the tape which seals the toner drum during transit. You have to pull on the tab which in turns yanks the sealing tape out after it.

Each HP cartridge has a small instruction sheet included which shows the location of the pull-tab. Perhaps your Xerox cartridge came with a similar diagram sheet?

Masking Tape Gives TN-350 Toner a Second Life, August 25, 2008 By C. MACPHAIL "cmacphail3"
After the "Toner Life End" message appears, it refuses to printeven one more copy. Offensive...until you show it who's in charge.

Remove the cartridge and find 2 clear plastic port holes, one oneach side. The printer shines a light through these to decide when toshut you off. But it's too sudden and too early.

Cover one or both windows with a small piece of masking tape. I get about 3400 copies per cartridge instead of 2400.
