Printer Self –Tests
Printer Self –Tests
With the exception of testing the interface between the printer and the host
computer (and the associated data cable), you do not need to send data from
the host computer to the printer to test printer operation. You can use the
printer's built–in diagnostic tests to check many of the functions of your
printer, including print quality and overall operation. These diagnostic tests
include the following:
•
Printer Demonstration
Demonstrates all the functions and features available on the printer.
•
Print Error Log
This test prints the contents of the printer's internal error log.
•
Print Ribbon Log
This test prints a log of ribbons that have been used in the printer.
•
Ripple Print
A "sliding" alphanumeric pattern used to identify missing or malformed
characters, improper vertical alignment, or vertical compression.
•
All E's
A pattern of all uppercase letter E's used to identify missing characters,
misplaced dots, smeared characters, improper phasing, or light/dark
character variations.
•
All H's
A pattern of all uppercase letter H's used to detect missing characters or
dots, smeared characters, or improper phasing.
•
All E's + FF (Form Feed)
A pattern of all uppercase E's repeated for ten lines and followed by a
form feed to the next page top–of–form, used to identify paper motion or
feeding problems, such as paper path obstruction or improper forms.
•
Underlines
An underline pattern useful for identifying hammer bank misalignment.
•
Clear Error Log
Clears entries in the error log.
