Canon BJ-30 manual FUNCTION 3 Text scale mode, FUNCTION 4, 5 Top margin, FUNCTION 6 Smoothing mode

FUNCTION 3: Text scale mode

This setting determines how many lines fit onto a page by adjusting the line spacing. If you are using a software application that assumes 66 lines will fit on each page, set this FUNCTION to ON. The printer will reduce the line spacing by a factor of 62/66, which is from 62 lines per page to 66 lines per page if line spacing is set to 6 lines per inch (lpi).

FUNCTION 4, 5: Top margin

Use these functions to set the size of the top margin. Once selected, this setting takes effect when the next sheet of paper is fed.

The default setting is 0.12 inch (3 mm) because the default printer control mode is BJ mode. When you change the control mode to Epson LQ mode, the top margin will be changed to 0.33 inch (8.5 mm).

FUNCTION 6: Smoothing mode

Set this FUNCTION to ON to enable the Smoothing mode, which is used with the BC-10 Black BJ cartridge only. When Smoothing is enabled, the printer refines your printout by polishing away the jagged edges and ragged stair-stepping curves of characters and graphics. This results in sharp and crisp printout at 720 (horizontal) by 360 (vertical) dots per inch.

NWhen to set FUNCTION 6 to ON

Enable Smoothing mode when printing from MS-DOS applications with the BC-10 Black BJ cartridge using the printer’s internal fonts. Smoothing is especially effective for printing double height, double width, italic characters, and combinations of these characters.

FUNCTION 7: Automatic power off mode

The printer is idle when it receives no data and no instructions from the operator panel. This FUNCTION setting allows you to configure your printer to turn itself off automatically if it is continuously idle for 30 minutes. This function is a convenient way to maximize battery life. The factory default is Disabled.

FUNCTION 8: Font typeface lock mode

This function is called the Font typeface lock feature. It determines whether the font selected from the operator panel may be overridden by a DOS software application. The factory default is Disabled.

When you set this FUNCTION to OFF, the fonts specified by your software applications are used at print time. Set this FUNCTION to ON when you want the fonts specified through the operator panel to take precedence over the font selections made by your software application.

FUNCTION 9: Input/download buffer

This function controls the size of the input and download buffers. The amount of memory reserved for the data input and download buffers is 35 KB in BJ mode and 26 KB in Epson LQ mode. This function specifies whether to use this memory exclusively as an input buffer, or to split it between an input buffer and a download buffer. The factory default setting specifies that the memory is used exclusively as an input buffer.
