Quick Setup Guide, Adjusting the Head Gap

Windows-Based Systems:

Install the Printer Driver

To print from a Windows-based system, install the printer driver located in the Drivers folder on the CD supplied with your printer. This driver provides full printer capability and will automatically switch the printer to the correct emulation that your software requires.

Use the Add Printer Wizard to install the driver:

1.Place the CD in your CD-ROM drive.

2.Click Start → Settings → Printers.

3.Click Add Printer. The Add Printer Wizard appears.

4.Follow the on-screen instructions.

5.When you are prompted to select the manufacturer and printer model, click Have Disk, then browse to the appropriate CD directory and double click the inf file:

•Windows XP \Drivers\WinXP\English\Oemprint.inf

•Windows 2000 \Drivers\Win2k\English\Oemprint.inf

•Windows 98 and Windows Me \Drivers\Win98_Me\English\Oemsetup.inf

•Windows 95 \Drivers\Win95\English\Oemsetup.inf

•Windows NT 4.0 \Drivers\NT40\English\Printer.inf

6.Follow the on-screen instructions to finish.

Non-Windows Systems:

Set the Emulationin the Printer Menu

If you are using a non-Windows system such as LINUX,® a DOS® program, or an older application such as Word

Perfect® 5.1, you must set the correct emulation in the printer menu. If the menu is set to the wrong emulation, you will see strange characters, incorrect fonts, etc.

Your printer emulates the following printers:

IBM (2480)—factory setting; Epson FX (ESC/P); OKI Microline

Note: If you are replacing a Microline ML 184 printer, set the printer menu to match the emulation being used for the existing printer.

To change the printer emulation in the printer menu:

1.Load continuous forms paper.

2.Turn the printer off.

3.Press and hold SELECT while turning the printer back on. The printer enters the Menu Mode.

4.Press FORM FEED. The first line prints showing the factory default emulation:

5.Press TOF SET until the emulation you want appears.

6.Press PITCH and MODE together to save your settings and exit the printer menu.

Note: If your Non-Windows system requires you to select a compatible printer driver in your software, see the Online User’s Guide for information to do this.

Adjusting the Head Gap

The head gap is the distance between the print head and the platen roller. When you use envelopes or multi-part forms you will need to have a larger gap than when using plain paper. Use the recommended head gap to ensure the best print quality and easy paper feed.

CAUTION: Incorrect setting of the print head gap can cause print head damage or ribbon jams.

To adjust the print head gap, move the colored lever located to the left of the ribbon cartridge (a), to the correct position for the type of stationary being used, as detailed below:

Paper Type	Weight	Lever Position

Single part paper	14 - 20 lb (52 - 75 gm)	1,2
