18-Wire printhead resistance checks

The printhead is electromagnetic and has two columns which contain 9 wires. The left column (viewed from the
platen or paper side) is the B side with wire 1B at the top. The right column is the A side with wire 1A at the top.
The A side is raised and lowered (by an electromagnet), to increase print quality. Needle 5B is used for AFTA
paper thickness measurements. The printhead is connected to the Engine board by a 22-pin cable, a 26-pin
cable, and a 12-pin cable. (The 4247 Model Z03 does not use the 12-pin cable.)
