According to my service manual, this error is occurring during the Power On Self-Test. While it is a "soft" error, it normally can only be resolved by replacing the Image Processor Board. But wait! There's more! Here may be a way to reset without the expensive replacement: The most likely cause is that the Image Processor Board has not successfully loaded its NVRAM contents (instructions) into RAM. All print engine operation halts, and will only become ready when the Image Processor Board successfully boots. 1. Check for media or debris in the paper path. 2. Power cycle the printer. 3. Verifying Image Processor Board failure: a. Power-off the printer, and remove the Image Processor Board. b. Power-on the printer. Wait at least 5 minutes while the print engine initializes. If there was a problem with the Image Processor Board, it will now not affect the Engine Control Board. c. If characters appear on the Control Panel display, the Engine Control Board is functional and the problem is most likely with the Image Processor Board. d. Turn off the printer and reseat the Image Processor Board and turn on the printer to determine if seating was the problem. e. Perform a PostScript NVRAM reset, see "Postscript NVRAM Reset" on page 6-9. f. Turn off the printer and systematically remove individual optional components from the Image Processor Board to isolate a possible problem component. g. Replace the Image Processor Board. I wish you luck with this repair.

id try lubing the feed rollers well the metal bars where they contact the chassis and lube gears and stepper motors. its been awhile since ive had my phazer. i traded it last year to my church pastor but try that. radio shack sells a teflon lubricator part no. 64-2301a and im certain amazon also sells them.
