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. They are described in more
detail in the Maintenance Manual.
•
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.
•
Ethernet Test. Prints the Ethernet statistics stored on the Ethernet (if present).
•
Acoustics. A particular test pattern that is used to measure acoustics.
•
Demo. Demonstration of various print attributes.
•
Dice 5. Pattern used to measure print density.
•
Prnt Ribbon Log. Prints log of cartridge installed in the printer.
•
Checker. For factory use. This pattern helps identify marginal printhead elements, quality of edge
sharpness, and uneven print quality.
•
Weld Patch Log. Prints log times for ribbon starts, welds, and ribbon stops.
•
Novram Err Log. Prints detailed information about the most recent Novram related failure that has
occurred. It is useful when the front panel reports "BAD NVM" or "ILL NVM" error types. Contact the
Customer Solutions Center and provide this information if such an error occurs.
