HP 900 manual Serial, Parallel, and USB Problems, If the left edge of printed output is missing

Troubleshooting

Solving Problems

∙Make sure the infrared light path is not blocked.

∙Check for paper in the printer or other printer errors.

∙Make sure Windows is running—infrared printing is supported only while Windows is running.

∙In BIOS Setup the infrared port must be enabled and the mode selected. The mode must match the driver. In Windows 95, an infrared driver must be installed. For details, refer to the driver’s Readme file located in \Omnibook\Drivers.

∙Click Start, Help and use the Print Troubleshooter. If you’re using Windows 2000, click Start, Help, Troubleshooting, and Print.

∙See “Infrared Problems” on page 103.

If the left edge of printed output is missing

∙If the printer you are using is a 600-dpi (dots per inch) printer, try selecting a compatible printer driver for a 300-dpi printer. For example, for a 600-dpi HP LaserJet printer, try using the HP LaserJet IIIsi driver (300-dpi). Certain applications may not work properly with 600-dpi printers.

Serial, Parallel, and USB Problems

If the serial mouse doesn’t work

∙First, make certain you followed the manufacturer’s installation instructions completely and have installed the mouse properly.

∙Check that the cable is properly connected.

∙Check settings in Control Panel (and in Windows NT Diagnostics).

∙Make sure the serial port is working—see the next heading.

∙If you have problems with a serial mouse that you can’t resolve using the suggestions in the OmniBook manuals, you should consider using a PS/2 mouse instead. The PS/2 bus provides better support for pointing devices than the serial bus does, especially when docking and undocking under power management.

If the serial or parallel port is not working

∙Check that the cable is properly connected.

∙Check settings in Control Panel (and in Windows NT Diagnostics).
