Printer Tests

These tests are used to check the print quality and operation of the printer.
NOTE: Your authorized service representative will typically run the tests.
•
Shift Recycle. A sliding alphanumeric pattern which identifies missing or
malformed characters, improper vertical alignment, or vertical
compression.
•
All E's. A pattern of all uppercase E's which identifies missing characters,
misplaced dots, smeared characters, improper phasing problems, or light/
dark character variations.
•
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 Adj.. 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.
•
Acoustics. A particular test pattern that is used to measure acoustics.
•
Adapter Test/Ethernet Test. Prints the Ethernet statistics stored on the
Ethernet adapter (if present).
