printhead’s spacing adjustment by twisting a flat-blade
screwdriver in the adjustment slot to move the printhead’s
position until the indicator reads the correct value.

measure the larger of the two gaps.

between the printhead and the drum. Repeat the adjustment.
Confirm the left side is still in adjustment. If not, alternate
between the two sides until both sides read 0.0030

properly seated. Reconnect the two printhead ground wires to
the printer frame.

set the correct gap between the “hot” printhead and the drum.
