Nylon Diagnostics This section discusses diagnostics at power-on and how to do the printer test. Power-On Diagnostics The following tests are performed when the printer is turned On. • RAM Test • Font ROM/Microcode Sum Test • Timer/Interrupt Controller Test • NVRAM Test • Switch Scan Test of the operator panel • Carrier Initialization • Paper Feed Initialization If any errors occur during the tests, a combination of blinking LEDs indicate which test failed. Printer Test You can run a Printer Test to aid in problem determination. In addition to the normal power-on internal tests (see "Power-On Diagnostics" on page 15), the printer test generates a sample printout. This test printout can be printed either with or without connecting the printer to your computer. Section 1: Introduction 15
