thorough discussion of your printer and its output options, see the ImageWriter II Technical Reference
Manual.
Changing Settings With DIP Switches
The ImageWriter II has two DIP (dual inline package) switch blocks, designated SW1 and SW2. Both are
located toward the lower left corner of the printer. (You may have to slide the ribbon deck to the right in
order to see them.)
Location of DIP Switches
SW1 has eight switches and SW2 six switches (two of which shouldn’t be touched: SW2-5 and SW2-6).
Tables A-1 and A-2 show the default settings for each block and describe the functions of the switches.
Do not touch switches SW2-5 and SW2-6. These are reserved for authorized Apple technicians to adjust
hammer-fire timing.
Default Settings for SW1
Note: Some DIP switches use Off for Open and On for Closed.
