Our Lexmark 1000 typewriter is not printing in the usual bold,black print we're used to just recently. We have installed a brand new plastic tape - #1380999 and see no improvement. It appears the striker is not hitting perpendicular to the Daisy wheel because the letters are grayish along the left side and along the very bottom of the letters typed. This is happening more than 50% of the time. Is there any adjustment for the striker unit to correct this problem or may it be something else that needs some tweaking??
