3–36 Troubleshooting
♦ Phase Printer A hammer timing test that permits you to adjust the
hammer phase value. The hammer phase value is a timing parameter that
controls the vertical alignment of dots in character printing. The
numerical units are relative; they do not represent a physical
measurement or value. There is no “correct” value or range. The factory
prints the initial phase value on the aluminum casting of the shuttle
assembly, next to the motor housing. Use this value as your starting point
when adjusting hammer phasing.
♦ Paperout Adj. This test prints a vertical comb pattern. You will use this
pattern when you do the end of forms (paper out) adjustment procedure.
The comb pattern lets you measure the number of dot rows from the
completion of a paper out fault to the end of the paper.
♦ Burnin Test Use of this test is not recommended. This test is used by
the printer manufacturer to burn in the printer prior to shipment, and has
no value as a maintenance tool.
