! Never remove the ink cartridge from the carriage unless ! ! ! ! !
this manual specifies to do so. When transporting the printer after installing the ink cartridge, be sure to pack the printer for transportation without removing the ink cartridge. Use only recommended tools for disassembling, assembling or adjusting the printer. Apply lubricants and adhesives as specified. (See Chapter 6 for details.) Make the specified adjustments when you disassemble the printer. (See Chapter 4 for details.) Once the ink cartridge mounted on the printer is removed, air comes into and creates bubbles in the cartridge. These bubbles clog ink flow and eventually cause printing malfunction. For this reason, If you need to remove any ink cartridges during disassembling, be sure to replace them with new ones. Because of the reasons above, make sure to return the printer to the user with new ink cartridges installed.

1. Start the service program and access the main menu. 2. Select USB ID input/check and click OK. The USB ID input/check screen appears.
5.2.2 USB ID Input
The USB ports of this printer are located on each board of the card reader part and printer part, and each part has its own USB ID. This is because, on Windows 98 and iMac, the USB port driver controls its devices by referring to the USB IDs. For the reason above, the USB ports of the printer part and card reader part are independently assigned. However, since the printer operates combining the both parts, it need to have the same information in their USB IDs. So this section describes how to input USB ID by using the service program.
C A U T IO N
Input USB ID under any of the following circumstances:
! When you replace either control board:
Since ASP control board does not have a USB ID, you need to get the old board's USB ID by referring to the other board's ID and input it as the USB ID of the new board. ! When you replace the both control boards: Unless you know their USB IDs, you need to input the printer's serial number to let the service program automatically define and store the new USB IDs for the both boards.
