Chapter 4 DIAGNOSTICS
• 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.
• 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.
Test Width
Set this parameter to run the self-tests at full width or 80 columns.
Paper Out Dots
CAUTION Only authorized service representatives should set this parameter.
This parameter is used to adjust the paper out distance from the perforation;
you can specify where the last line on the page will print when there is a paper
out condition. Setting this parameter correctly prevents printing on the platen.
System Memory
Displays the amount of RAM installed.
