Troubleshooting the Power Supply on a HP LaserJet 8150

The LaserJet 8150 has a duty-cycle of 150,000 pages a month.

HP's LaserJet 8150 multi-function printer can print 32 pages a minute on letter-sized paper. It has a duty-cycle of 150,000 pages a month (the number of pages it can print in a month without undue stress to the machine) and includes a 220 MHz processor. Power consumption is considerable, as is common in older printers. The printer uses over 600 watts when operating, and uses between 145 and 165 watts when in standby, depending on model. Problems with the power supply on the HP LaserJet 8150 can be rectified by following some troubleshooting steps.

Instructions

1. Remove the power cable from the wall and plug another appliance in to the same outlet if the printer won't turn on. If the other appliance works, the power outlet is working.

2. Look at the specification label at the back of the printer near the power inlet and verify that you are using the correct specification model for the region that the printer is operating in. There are two variants, a 100-127 volt unit and a 220 to 240 volt unit. In the United States, you need to use the second of the two.

3. Plug the printer directly into the power strip or wall power outlet. The printer doesn't use a power adapter--like a laptop--for converting AC wall power to DC.

4. Allow the printer to go into power saving mode. If the printer gets quiet, it hasn't switched off. After 30 minutes, if nothing has been printed and you haven't turned the printer off, the fan will stop operating. Power consumption is greatly reduced. Print when you are ready and the HP LaserJet 8150 will "wake up." Turn the printer off at the end of the day for total power savings.
