4227-300 Button Test Pressing each operator panel button causes the alarm to beep. Pressing multiple buttons simultaneously results in no beep. Return to the Service Menu by pressing Menu/Quit. Factory Setting Factory Setting allows the selection of the default page length and code page from U.S. defaults (11", Code Page 437, Character Set 1) to Non-U.S. defaults (12", Code Page 850, Character Set 2). Printhead Bank This allows the 18-wire printhead to be set to use the left bank only, the right bank only, or both banks (default). This allows the printer to continue to print with a damaged printhead or cable. Jam/PSet Sensor Test This test enables or disables the PSet and Jam sensors on the left tractor. Impact force Impact force enables the striking force of the printhead pins to be changed. Three selections are possible. • Normal Auto-This is the default value. Impact force of the printhead pins is adjusted automatically for paper thickness. • High-This is the highest impact force and overrides the Normal Auto selection. High pin force is used to obtain clearer print on medium thickness forms. Leaving the printer in High can damage the printhead, especially if printing on single-sheet forms. • Normal 1P-Disables the automatic setting of the impact force. Normal 1P is used to print in normal force when thicker print media is used, such as labels. Log clear Clears the error log. 3-4 Service Manual
