15.Corrupted Flash ROM

First reload Firmware (direct connect a PC via a 6 foot/2 meter IEEE 1284 compliant parallel printer cable), then reload Boot Code, and finally replace the Main PWA (to check the Flash ROM) for the following problems if issue cannot be solved by any other means:

Horizontal banding (1cm spacing) Microbanding (.5 to 2mm banding)

16.For printers which cease printing during overnight print runs ensure the room lights remain on (or is consistent from the time media was measured) as this may affect paper sensor performance leading to incomplete print jobs.

17.For O/R Error Messages ensure both L and R values indicate numerical ranges of ...107800 through ..1082000. Any other numerical range could indicate a failure of the respective carriage PWA. A target range is typically displayed as P10.800; indicating the target cartridge drive voltage for this PWA is 10.8 vdc.
