CG4 Series Service Manual Page 4-29
4.15 FACTORY USB BOOT DOWNLOAD MODE
This mode enables the printer to connect multiple printers to a single USB port of the host computer.
In factory USB boot download mode, the printer motion will be based on the boot download mode. In this
case, the returned contents of descriptors shown below are different because serial number is not returned.
USB will be selected automatically regardless of interface you specified.
If executing auto reboot in factory USB boot download mode, the printer will be activated in factory USB
interface mode.
Notes:
• If you missed the chance to release the FEED/LINE button in step 2 above, just keep holding the
FEED/LINE button and wait for the next cycle.
• If you released the
FEED/LINE button at the wrong ON LINE (POWER) indicator, just turn off the power
and restart the procedure.
