Lift the entire mechanism/board assembly and place it in the cabinet.
The mounting shelf (in the rear of the mechanism) should fit under the row of ribs
along the back inside of the cabinet. The front of the mechanism assembly should now
drop into place.
If necessary, gently push the front corner of the PC board closest to you.
The assembly is correctly positioned when:
•
The PC board is in its guide slot at the cabinet bottom
•
The printer mounting hole is lined up with the screw hole on the bottom
•
The printhead cable is inside the cabinet and is not protruding through the bottom
Hold on to the entire cabinet assembly and turn it over.
Replace the bottom screw and tighten gently.
Do not overtighten.
Attach the ground strap to the PC board.
Position the cover, taking care to align the buttons with the switches underneath.
Push on the left corner until that latch snaps.
Carefully push out on the inside back of the cabinet with your left hand, while pushing
down on the L cover with your right hand.
This will snap the L cover into position.
Hold the top cover vertically over the hinge brackets in the printer cabinet.
Align the hinges.
Push down gently until the cover snaps into place.
Place a roll of paper in the paper bin area so that the loose edge feeds up from the
bottom of the bin toward the printhead area.
Close the receipt cover by pushing it down until it latches firmly into place.
Turn on the printer.
Run the print test.
