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.
