Accessing the EPSON Status Monitor 3
You can access the EPSON Status Monitor 3 by selecting the
EPSON Status Monitor 3 alias in the Apple menu.
Note:
❏ The EPSON Status Monitor 3 appears automatically when an error
occurs.
❏ The appropriate printer port must already be selected in the Chooser
so that necessary information can be received from the selected
printer driver when the EPSON Status Monitor 3 starts. If the
printer port is not correct, an error will occur.
❏ If you change the printer driver in the Chooser while the spool file
is printing in the background, output to the printer may be
disrupted.
❏ Printer and consumable products status information appears in the
status window only if the Chooser is acquiring status normally.
