Appendix A:  Using Monitor3 with Your 
iMac 
The Monitor3 utility lets you continue to work on your iMac while 
your document is printing (though printing and processing may be 
slower). The Monitor3 dialog box lets you check on your print jobs 
and cancel, pause, or restart them.
See the next section to turn on background printing and increase 
the memory allocation for Monitor3.
Setting Up Monitor3
1
Open the Chooser from the Apple menu and select the icon for 
your printer (SC 600SC 440SC 640, or SPEX). Then select 
the USB Port.
2
Under Background Printing, click On and close the Chooser.
3
To increase the memory allocation, select EPSON Monitor3 in 
the Extensions folder in your System folder. Then choose Get 
Info
 from the File menu and set the Memory Requirements to 
2000 or 3000, depending on your system’s available RAM.
Now see the next section for instructions on using Monitor3.
