- The Obvious: (but sometimes overlooked)
Check fuses or circuit breaker (if you are able to do this) if your printer is plugged in but doesn't start. Remove the printer to PC USB or parallel cable and put back in to check they it hasn't been knocked out of place. Also check on your PC through Device Manager and look for yellow exclamation mark or red X next to any USB devices. If the printer has an online/offline button check this hasn't been switched accidentally.
- Update your printer driver
Go to the manufacturer's website to install new drivers. This may be useful for Windows PC users
Windows XP: Select Start-Printers and Faxes-Add a Printer (from Printer Tasks in Printers and Faxes window)
Windows 98, ME, 2000: Uninstall the printer driver and reinstall.
Select Start-Settings-Printers. Right click your printer icon-select delete and Add Printer.
- Print Test Page:
This can either be done through the printer properties on the computer or on the printer itself. If the test page looks ok then check the cables, PC or software. (see point 2 on drivers)

- Paper Jams
Pull any jammed paper from the printer in the direction it would normally come out of printer. If it keeps jamming then turn it off and let it cool down. Take the toner cartridge out and check there is nothing obvious inside printer that is obstructing the paper movement. Don't poke around too much as you may damage your printer which won't be covered in your guarantee.
