1. General Information
Description
The Lexmark Form Printer 4227-100 and 4227-200 are dot matrix, electro-mechanical printers that form characters on print media using a printhead and fabric ribbon. The printhead is composed of 18 miniature solenoids containing print wires and operates on electromagnetic principles. When a solenoid is energized, the small print wire pin is “fired” toward the ribbon to make a dot on the paper. The printer receives commands in the form of an electronic data stream from the PC through the parallel or serial port connector. The printer logic receives and translates the electronic data stream into carrier returns, line spacing, characters, or graphics as instructed.

Voltage, Ground, and Continuity Readings
Voltage Readings
All DC voltages must be within +5% through -10% of the values to be considered correct. Unless stated otherwise, all connectors should be connected normally when a voltage measurement is done.
When a “Line Voltage” measurement is to be done, the voltage on United States and Canada machines should be between 100 V ac and 127 V ac. On World Trade machines, the voltage is according to each country’s specification.
Ground Checks
To check for a correct ground, measure the voltage between the ground and a known good voltage source. The voltage measurement must be the same as the source voltage to consider the ground is correct. Continuity measurements may be used to check grounds, however, be sure to measure to a known good ground using the lowest ohms scale and check for zero ohms.
Note: Always unplug the power cord before doing any continuity measurement.
Continuity Readings
When measuring continuity, be sure no back circuits affect the measurement. If necessary, unplug connectors to remove any back circuits. Zero the ohm range on the lowest scale (X1). An open circuit will read infinity. A circuit with correct continuity will read zero ohms.
