9. SCANNER INSPECTION MODE The printer incorporates a scanner inspection mode, the factory inspection program mode. The factory inspection program mode provides two types of test mode, and then each test mode supports a few test programs. Refer to the table below; Scanner panel test Line-feeding test Maintenance copy test Continuous test mode (scanner panel test / line-feeding test / maintenance copy test) Maintenance copy test N/A To enter the factory inspection program mode, you can choose one of the following; A) Turn on the power switch of the printer while pressing the Stop and Enlarge keys. B) Press the Stop and Enlarge keys after turning on the power switch of the printer. Note: Once you press any keys other than the Stop and Enlarge keys when the power is turned on, the printer cannot enter the factory inspection program mode any more unless power is turned off and the select sequence is repeated. The printer enters into Test Mode A immediately after entering the factory inspection program mode. If you want to switch between these two test modes, press the Stop key. The following sections describe the detailed operation of each test mode. 9.1 Test Mode A When the printer enters into Test Mode A, 'A' is shown on the seven-segment LED.

When all of the keys are being pressed then all four lamps are ON. 3) When the four keys are recognized, the Photo lamp flashes, and each of the seven segments on the LED is turned on in sequence.
