4.1.11. Reset to factory default settings
EscCRFD (27)(13)(70)(68) <1Bh><0Dh><46h><44h>
• This command causes a factory reset to be performed, restoring all the printer’s factory default settings. See
the section “Factory default environment” for a list of the factory default settings.
• You can also perform a factory reset using the printer’s control panel or remote printer console program (see
the User Guide).
4.1.12. Reset to user settings
EscCR!#R (27)(13)(33)#(82) <1Bh><0Dh><21h>#<52h>
• # can be 0, 1 or 2.
• #0 indicates the current settings are restored. Unlike the Esc E reset command, the Esc CR!0R command
resets the input buffer.
• #1 indicates the user settings 1 are restored, if the printer supports multi user settings.
• #2 indicates the user settings 2 are restored, if the printer supports multi user settings (Except for HL-7050).
• Depending on the model, you may be able to lock the control panel settings (“SETTING LOCK=ON”). In
that case, parameters 1 and 2 are ignored.
4.1.13. Printer self test
Escz (27)(122) <1Bh><7Ah>

on the model, you may also see the test pattern for HRC setting.
