Setting the DIP Switches
The LQ-510 has two sets of DIP (Dual Inline Package) switches located under a small cover above the control panel. By changing the settings of these switches, you can control various printer features, such as the character set and page length. The new settings become effective when the printer is turned on, reset, or initialized.
DIP switch settings are shown in the DIP switch tables starting on page 3-7. Descriptions of all the DIP switch functions begin on page 3-9.
Changing a DIP Switch Setting
To change a DIP switch setting, first turn off the printer. Then open the DIP switch cover and use a pointed object, such as a pen, to change the DIP switch settings. A DIP switch is on when it is up, and off when it is down.
The new DIP switch settings take effect when the printer is turned on.

The DIP Switch Functions
Auto line feed
When auto line feed is on (DIP switch 2-4 on), each carriage return code (CR) is automatically followed by a line feed code (LF).
Input buffer capacity
The input buffer stores data from your computer. If you want to free your computer for other tasks while the printer prints, change the setting of switch 2-5 to 8 KB (on). Before using user-defined characters, however, be sure to set the input buffer to 1 KB (off).
Printing direction
With unidirectional printing, the print head prints in one direction only. This allows for precise vertical alignment, making it ideal for printing graphics such as lines and boxes. When DIP switch 2-6 is off, the printer prints unidirectionally; when it is on, the printer prints bidirectionally. Either setting can be overridden by a software command (ESC U). To achieve precise vertical alignment without the slower printing speed caused by unidirectional printing, see your authorized service dealer for adjustment of your bidirectional print settings.
Tear-off mode
When DIP switch 2-2 is on, the short tear-off mode is on. This feature automatically advances continuous paper to the tear-off position, and then reverse-feeds the paper to the loading position.
See the section on using short tear-off later in this chapter.
CAUTION: Do not use the short tear-off mode with labels.
