Copier Locks up L1 Error Code

I looked it up in the manual and it says that the copier is locked. Actually its a 1645CS. I unlocked it, turned it off and back on again but I still get the same error. The copier barely starts up and quickly locks up.

"I've had this trouble recently. The lock switch is not so a lock switch but a circle object to the left of the printer and under the scanning part. I had to turn all the way to the unlock side and restart the copier.
What Bad place to put an lock/unlock switch"

This lock switch is for Transport,
It locks the Scanner, so as to not damage while in transport.
When installing/setting up the machine this should be removed?
If not sometimes people accidently bump it to lock position.
It can be easily removed with a Flat Screw driver. It will pop out easily..

It's possible the rail for the scanner has become gummed up. Remove the glass and use light oil, (tri-flow, 3-in-1, etc) on rail.

If unlocking and lubing the scanner rail does not work it will be the main pcb

First run a copy from the glass and one from the document feeder. If the line is only visible when running copies from the document feeder the problem is a dirty scanner glass. Clean the small piece of glass on the right hand side next to the larger original glass. Old style lighter fluid works best like Ronsonal or Zippo.(wick type - not butane) 2. If the problem shows in both copies you will most likely need a new drum unit, but you may be able to solve the problem by removing the drum from the holder by expanding the rear frame slightly until you can lift the drum out and then blowing out the charger unit above the drum with compressed can air. Reinstall the drum in the holder and check copy. ALWAYS HANDLE THE DRUM WITH A SOFT PAPER TOWEL - DO NOT TOUCH THE DRUM SURFACE or allow it to bump against hard surfaces.

I Don't speak Spanish but if your toshiba e-Studio is having an L1 error it likely means that your scanner is locked, if you reach into the output tray there is a knob on the front left hand side that locks your scanner in place. Turn it and your copier should work again.

The Sharp AL-1540CS copier produced a sheet all black then gave the error code L-1. The manual said to ''unlock'' the scan head lock, but after looking, it was already unlocked. After restarting the...

L1 or L1-00 indicates Scanner movement failure. The scanner is the part under the glass that lights up and moves back and forth. So if you lift up the feeder so you can see the glass, turn the machine off for a few seconds then back on. Watch the movement of the scanner. It should move right and inch or two then back to the left. If all goes well the copier should come to ready. Lay a piece of paper on the glass and press the print button to watch the scanner movement. If it binds up or does not scan correctly there are 2 possibilities.
1) your scanner lock is engaged and is preventing the scanner from moving. Check the clear plastic dial located under the far left upper side of the copier, near where the paper exits the machine. Make sure it is in the unlocked position.
2) Your scanner rail is dirty and dry. This rail can be seen under the glass towards the back of the copier. The scanner rides on this rail. It is very common for these to get dirty and for the grease to dry up causing the scanner to freeze up on the rail. The glass must be removed and the rail cleaned and lubricated.
Just power off then on the copier to reset.

Printer ar168D Error L1-00

The L1-00\r\n error indicates the scanner didn't return to it's home position or is locked and can't leave the home position. There is a lock switch (designed to lock scanner into place for safe transport) located to the left of the copier and just under the scanner. It's a plastic dial that needs to be turned to the "unlock" position. Once done, your problem should be fixed.
