    All connections appear to be OK. Printer does not respond.

    Do these things just die??

  • Anonymous Dec 11, 2007

    My Laserjet 4L one day just wouldn't turn on when I sent a document to it. I disconnected the I/O cable, pushed the blue top button (below the error lights) and nothing happens.

    As I moved shortly thereafter, I've misplaced my operating manual.

    Is there a fuse or hidden switch which could be preventing the printer from powering up?

    Without connecting the I/O cable, shouldn't the blue button when depressed cause a print test sheet to be generated? Would it help in troubleshooting/repair if I reconnect the I/O cable?

    Any advice would be appreciated.

Replace the power switch. A fairly standard switch type. You may get one off ebay or similar site. If push came to shove, you could just replace the power input assy.

In general, yes. Some model-specific features won't work with other models, of course. For example the 4P does PostScript while the 4 does not. But as long as the customer confines himself to basic printing, the 4L driver should work properly with any of the 4-series printers.

My HP LaserJet 4L printer just makes a grinding sound when I attempt to get it to print. It makes the sound for several seconds and then the Paper light starts to flash without printing
Common issue with these older 4L printers. The problem is a small plastic gear on the main drive motor has cracked. This is what causes the noise and since the machine is not "running" there is no paper feed and thus the paper jam light. Basically there is no drive to any of the printers components. May be hard to find a replacement motor these days but that is what you would need to fix the printer.

HP Laser 4L driver for USB port
Not all USB adapters are the same, you need the one that is made for your printer, I would try a different adapter before going too deep, because when you plug it in your computer should see it even without drivers.

HP 4L printer indicates no paper when the tray has
When you removed the paper jam, was the paper torn? If so, did you ensure that you found all the pieces. (Put the piece of paper back together like a puzzle to verify). There could be a piece of paper stuck in the printer that is causing the paper sensor to fail.
The other possibility is that when you removed the paper jam, something became dislodged in the printer. Forcefully removing paper from the printer can cause this.
