If you can go to Google Images and look at cameras from the 1950s and 1960, you'll see little levers toswitch from X to M and back to X. This longer time allows the flash bulb to get brighter and brighter, and when it is at its brightest, the shutter opens to capture the most light. With M-sync there's a longer time between when the flash goes off and the shutter goes off. The alternative to X-sync is M-sync, and M-sync is designed for use with flash bulbs - find a grandfather to tell you about them. Return the printer to your authorised Zebra partner.Anyway, what X sync means is that the camera is set up for electronic flash, and there is very, very little time between when the flash goes off, and the shutter opens (and then closes).Return the printer to an authorised Zebra partner.Įrror 9 Red and Red Green - The printhead or motor has had a critical failure.When it does, the printer will automatically resume operation.Įrror 8 Alternate Green Red - FLASH memory is not programmed.
