TROUBLE SHOOTING
The list below is intended to help the operator to correct possible
printout troubles or flaws in printout quality, and to decide when
assistance from the Service dept. of the nearest UBI distributor
is required. Note that most problems are due to operating errors
or normal wear of the printhead.
