Question about Office Equipment & Supplies
I purchased a HP LaserJet 6L around 3 years ago used. I replaced the rollers, and the whole front panel to the printer (sensor tabs were broke). All told, I still got the printer for a steal. It has ran fine for about three years, but here recently, it has started to make a high-pitched noise, and then it only prints lines on the paper. At first, it was only doing this intermttently, but now it doesn't even print at all, and makes the nerve-racking noise everytime I try to print. I replaced the toner cartridge, but it did not help. Even when I turn the printer on and off at initial start-up it still makes the noise. I am ready to take this baby apart again, but if it is either an easy fix, or not fixable, I don't want to waste my time or ruin it any further.
The problem with the screeching sound and horizontal lines printing is no lubricant for a small motor, not the main motor. To fix this problem, download the service manual which shows how to remove the case. You’ll need a phillips screwdriver and some machine oil or something similar to Z-Max. When the printer is apart and you’re facing it, on top there’s a compartment with a metal cover plate (shield) held by two screws. To the left is a spring loaded switching system that rocks into position when it’s called, and presses on the tab of a leaf switch. With the printer plugged up, you can press on the leaf switch which will engage the printers system, causing the printer to attempt printing. During this you’ll hear the screeching sound you’re describing. This is your test procedure during this repair. Next, notice the two multi-wire connectors at each end of the compartment. One bundle runs across the top of the compartment and connects on the other side. Remove both connectors and the two screws that hold down the shield; one holds down a metal pressure tab, also to be removed. This releases the shield exposing a small circuit board that has a control IC and a small motor. Three screws holds this circuit board to the printers plastic casing. Taking care not to handle the circuit traces (IC Static Protection Protocols), remove the screws and remove of the board. On this board is a small motor with it’s flywheel held down by a square weight and a pressure tab. Remove the top tab and the weight, turn the plastic guide to the side, and lift the flywheel away from the motor. Apply the lubricant to the shaft of the flywheel and reassemble the system. Try your switch test. Chances are, it’ll work without all that screeching. If you get that far, trust me, it’ll print. The "finge"

I have this exact problem as well. It printed a few pages, then gave some high pitch noise, the paper still rolled out. Then when I went to print a test page, it printed the paper with just lines and now, it won't even feed the paper into the printer.
Any luck on a quick fix?
