Test Pattern

Now you’ll see your LX-80 print something even though it’s not connected to a computer yet. Make sure that your printer has paper in it and that the power switch is off. Now, hold down the LF button on the control panel while you turn the printer on with the power switch. The LX-80 will begin printing all the letters, numbers, and other characters that are stored in its ROM (Read Only Memory) for the draft mode. When the printing starts, you can release the LF button; the printing will continue until you turn the printer off or until the print head gets near the end of the page. To see the same test in the NLQ (Near Letter Quality) mode, turn the printer on while holding down the FF button. Partial results of both tests are shown in Figure 1-9.
