E’s + TOF. A pattern of all E’s followed by a form feed to the next
page top-of-form, which identifies paper motion or feeding
problems.

All H’s. A pattern of all uppercase H’s used to detect missing
characters, misplaced dots, smeared characters, or improper
phasing.

All Underlines. An underline pattern useful for identifying hammer
bank misalignment.

All Black. A condition where all dot positions are printed, creating a
solid black band.

Shuttle Slow. Verifies proper operation by exercising shuttle and
ribbon motion at low speed.

Shuttle Fast. Verifies proper operation by exercising shuttle and
ribbon motion at fast speed.

Shuttle Only. Exercises only the shuttle at fast speed.

Phase Printer. Checks for wavy print. The initial phase value is set
in the factory. Run the test and check the quality. (The phase value
prints on the left margin.) If the print looks too wavy, change the
Phase Value parameter while the test is running. While the phase
printer test runs, press the DOWN key. To change the value, press
the PREV or NEXT key until the desired value displays and then
press ENTER.

Paperout Adjust. Verifies the current Paper Out Dots setting,
which determines where the last line of text will print when there is a
paper out condition. Setting this parameter correctly prevents
printing on the platen.

Burnin Test. Reserved for factory use.

Print Error Log. Prints the current log of errors. Most non-routine
faults (ribbon stall, voltage faults) are stored in the error log.

Clear Error Log. Clears entries in the error log.

Ethernet adapter (if present).
