Laser printers can be a source of electrocution, eye damage (from the laser), and burns (from the fuser assembly). The laser printer tends to have several high-voltage and high-temperature hazards inside it. To get the laser printer into a position in which you can observe its operation, it will be necessary to defeat some interlock sensors. This action will place you in potential contact with the high-voltage, high-temperature areas in the printer. Take great care when working inside the laser printer.

When troubleshooting a remote printer, check to see whether the printer is connected to the system through a print-sharing device. If so, connect the printer directly to the system, and try it. It is not good practice to use laser printers with these types of devices. A better arrangement is to install, or just use, an LPT2 port to attach an additional printer to the system. Beyond two printers, it would be better to use network-capable printers.

The easiest way to determine whether the printer is at fault is to run its self-test routine. If the self-test runs and prints clean pages, most of the printer has been eliminated as a possible source of problems. The problem could be in the computer, the cabling, or the interface portion of the printer. If the printer fails the self-test, however, it will be necessary to troubleshoot the printer's problem.
