HP 4000TN LaserJet. Was printing fine, then stopped. When I hit print on the computer, it goes through all the sounds and mechanical gyrations it always does and sends out a piece of paper as it always does, but there's nothing on it. Doesn't the low printer cartridhe show up as reduced quality for awhile? This just stopped cold from perfect resolution to perfectly blank. Any thoughts? Appreciate your help.

Hello, could be an empty toner, could be something blocking the laser from sending the image to the drum, or could be the laser went bad. May guess is try swapping toners first, that would be the best case.
Hope this helps....

First step is to find out if the fault is hardware. To do so print any of the printers internal pages (config page, event log etc..) If the internal prints are working ok, but blank when sending a job from the computer, then your fault is nothing to do with printer hardware.
If the printer internal prints are also coming out blank, then you have a hardware issue, so you may be looking at a faulty toner.. But could also be a failure of high volatge contacts, Transfer Roller, laser scanner etc..
