Lexmark 4I3 - Manual (Page 256)

The OCR-A and OCR-B print languages have fixed CPI and Print
Quality settings. For these print languages, the CPI must be set to
10 CPI and the Print Quality must be set to NLQ. While the
Configuration Menu allows scrolling through the various selections,
this message is displayed if either the CPI or Print Quality is
changed when the print language is set to OCR-A or OCR-B.
Note: When the print language is changed to any language other
than OCR-A or OCR-B, these options become enabled. They are,
however, left at 10 CPI and NLQ and require reconfiguring if these
settings are not suitable.
This message is displayed when Menu is pressed when the Menu
Lock feature is enabled. Contact your system programmer.
This message is displayed when either the access cover or the
paper door is opened and the printer is in the not ready state. The
not ready state is reached when Stop is pressed from the ready
state. If the printer is made ready and a print job is started, the
printer runs at a reduced speed if either the access or the paper door
cover is left open.
