EPSON FX-880/FX-1180 Service Manual

Printhead

You can check for an open circuit in the printhead’s solenoid coils by using a multimeter and the table
below.  Note that the test pin numbers shown in Figure 5-2 match the individual printhead solenoids (dot
wires).

Remove the printhead by following the instructions in Chapter 3.  Be sure to perform the platen gap
adjustment after replacing or re-installing the printhead.
