The initialization string contains codes that override the panel and
menu settings. To change your printer to ignore the reset code,
enter the Menu Mode, go to the Set-Up group and change the
setting for Reset Inhibit to Yes.
The I-Prime signal will automatically override any front panel
settings you have made. To eliminate this problem, enter the Menu
Mode, go to the Parallel Interface group and change the setting
for I-Prime to Invalid.
For more information on changing menu settings, see "Changing
the Menu Settings" in Chapter 3.
Problem
Nothing happens when I turn ON the printer.
Solution
Check the power cord connection to the outlet and to the printer. If
you are using a power strip, make sure it is turned ON, and that the
fuse hasn't blown or that the circuit breaker hasn't tripped. If the
solution is not obvious — call for service.
Problem
The printer does not print when the computer sends data.
Solutions
1. Is the SEL light on? If not, press the SEL key.
2. Check that the interface cable is securely connected to both
the printer and the computer.
Problem
I'm getting strange symbols, incorrect fonts, etc., when I try to print
a document.
Solutions
1. Check to be sure that the printer driver you have selected in
your software matches the printer emulation.
2. Please refer to the Printer Driver section for details of
emulations, then check the menu settings (see "Setting
Printer Defaults" in the Operating your Printer section).
