Chapter 3: Setup and Use Q8 Series User’s Manual
8
Interface Connection
The Q8 supports USB and RS-232 Serial interface connections.
Note: When connecting the Q8 to a computer via the USB cable, make sure to utilize the same USB port used during the
driver installation process, which enables the printer to retrieve needed commands or data from the PC. If the same USB
port is not available or not known, then in the printer’s Properties Dialogue Box, under the Ports tab, ensure the current
port location is checked.
To connect:
1. Make sure the printer is powered OFF.
2. The printer will identify the communication port automatically.
3. The default values of printer port can be obtained from the self-test report. (See Chapter 2: Operation Basics/
Advanced Functions/ Self Test)
4. Cable configurations for interfaces are found in Appendix A of this guide.
5. Please take the following measures to reduce cable noise.
- Restrict the length of the interface cable to less than 6’ (1.83 M) if possible.
- Keep the interface cable separate from power cords.
Installing the Ribbon
Note: Load ribbon only when using the thermal transfer printing method. Remove any ribbon that may be loaded when
using the direct thermal printing method.
Warnings:
(1) The Q8 supports ribbons with ink on the outside only. Check the ribbon package for ink side specifications.
(2) Always install a ribbon with the ink side facing outwards. The ink side of the ribbon must face the media and NOT
the Printhead
(3) If using a ribbon less than 110 mm wide, place the ribbon roll in the middle of the Ribbon Spindle for proper
alignment.
(4) Make sure the inner diameter of the ribbon is 0.5″ (12.5 mm).
To install the ribbon:
1. Open the right cover of the printer and turn the handle to the “open” position. Flip down the Printhead Module
Plate (see Figure 5-1).
2. Remove the ribbon from its package, and place the roll into the Ribbon Supply area, pulling out the Ribbon Release
Knob to insert the roll, and allow the leading edge of the ribbon to fall underneath the Printhead module. Ensure
the ink side of the ribbon is facing down (see Figure 5-2).
3. Lead the ribbon below the Printhead module towards the front of the printer.
4. Attach the leading edge of the ribbon to an empty core. Mount the core onto the Ribbon Take-up using the Ribbon
Loading Knob.
5. Turn the Ribbon Take-up Knob clockwise to ensure ribbon is tight and smooth (see Figure 5-3).
6. Close the Printhead Module Plate and turn the handle to the “close” position to lock the Printhead Module (see
Figure 5-3).
