Setting Of Dip Switches; Fig. 50 Removing Manual Paper Feed Knob; Fig. 51 Loosening All 4 Screws - Epson MX-80 Operation Manual

5. Setting of DIP Switches

In order to suit the user's specific requirements, desired control modes are
selectable by the two built-in DIP switches. The DIP switches (SW1 and SW2)
located on the control circuit board of the Printer are as shown in Fig. 54. To gain
access to the DIP switches, the upper case of the Printer must be removed.
NOTE: Turn the power off whenever you attempt to open up the printer case. Adequately
discharge static electricity which might be charged in your body, or it may cause
damages to internal electronic parts such as LSl's, IC's, etc.
Remove the manual paper feed knob (black knob on the right side) by pulling it
straight out, with firm but steady pressure. (See Fig. 50.)
I
Turn the printer upside down on a soft surface. With a Phillips type screwdriver
completely loosen all 4 screws. (See Fig. 51.)
Place tape over the 4 holes so the screws won't fall off when you tip the printer
right side up.
