Phaser 6250 Color Laser Printer Service Manual
Power On Self Test (POST)
The following tests are performed when the printer is powered on, after the boot
loader runs, and before the operating system is loaded and initialized.
POST diagnostics are intended to provide a quick means of isolating a defective
subsystem associated with the Image Processor Board, SDRAM, and ROM. POST
returns control to the boot loader and the operating system is loaded. The operating
system then loads the imaging processing software. If POST detected any soft errors,
a message is printed in a red box on the start page. If the start page has been turned
off, POST forces a start page to be printed. If POST detects any hard errors, both the
front panel and health LED blink the error code pattern, see "LED Blink Patterns" on
page 4-6.

After the POST tests have finished running, the Xerox ‘splash screen’ is posted to
the front panel and PostScript begins initialization.
