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.
General Information 1-1

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.
General Information 1-3
4227-X00
Maintenance Approach
The diagnostic information in this manual leads you to the correct
field replaceable unit (FRU) or part. Use the error indication table,
symptom/check table, service checks and diagnostic aids to
