4227-X00 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.
4227-X00 This is a versatile printer that combines excellent print quality along with the ability to print several print styles and graphics.
4227-X00 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.

4227-X00 Service Checks Auto Gap Service Check Theory of Operation: The Auto Gap Motor and Gap Home Sensor automatically set the printhead gap for the thickness of paper being used by rotating the eccentric carrier shaft. The printer detects maximum gap with the Gap Home Sensor, and minimum gap by driving the printhead against the platen. In addition to compensating for the thickness of the paper itself, the printer must increase the air gap for thicker papers.
4227-X00 Auto Gap can be set to Off to reduce time-to-print if the printer is always used with a single type of paper. With Auto Gap Off, the gap can be set to Manual Position 1 (thinnest paper) to 7 (thickest paper). With Auto Gap Off, Single Auto Gap has two selections: • • Fixed - the printhead gap is never changed. Open - the gap is opened when loading forms.
4227-X00 Auto Sheet Feeder (ASF) Service Check Auto Sheet Feeder Principles of Operation The auto-sheet feeder (ASF) feeds into the cut sheet paper entry throat. To use the ASF: • • The paper select lever must be set to cut sheet. Auto Sheet Feeder must be selected in the display menu. Continuous forms can be used with the ASF installed by moving the paper select lever to continuous forms and pressing Start to feed the continuous forms to the first print line. The ASF contains no electrical parts.
4227-X00 2 FRU Action Paper Feed If the paper does not feed, do the following: • Remove the ASF. • Be sure the base printer feeds paper correctly. • If it does not feed paper correctly, go to the “Paper Feed Service Check” on page 2-20. 3 Gear Train Be sure the ASF drive gear on the inside of the printer’s right frame rotates.
