Carriage won't drop

If you press a key does it type or try to correct? The escapement mechanism that allows it to move from space to space may be sticking and causing your problem. That mechanism just may need a flushing and lubrication. You will see a shaft that runs through the carriage. Try to turn it top to rear until it stops. if you hear a click then it has been turned the right amount. If it doesn't turn, then it is as far as it goes. Try hitting the spacebar and see if the carriage moves. If it moves, hit any key and see if it moves. if it moves, hit another key. If it doesn't move then your escapement mechanism needs to either be flushed and lubed or adjusted.

This is a very rare error. It refers to the value cam sensor within the purge unit.
The purge unit is where the head and carriage park when not printing. i suspect some foreign item (probably paper) is jammed in the purge unit. You may have fun in getting the carriage to move out of the way . Turn the power off. See if can move the carriage to the left with no resistance. if you can great. Shine a torch into the purge unit and remove any foreign item that may be there.
If the carriage wont move then power up and when you hear the motor run kill the power immediately by pulling the plug. keeps doing this unitl the carriage unlocks. If still no joy then its best left to a professional as the purge can easily be broken and its a massive job to replace it.

Good luck.

You would want to try and reinstall the print cartridges. It is possible that something is just stuck that is why you are hearing the grinding sound.
Let me know.

Make sure Carriage is engaged to Carriage Slide -- place Carriage Lever in lock position

Check if you haven't moved the scanner lock lever accidentally - find the lock lever (used to immobilize the carriage in transport) and move it to locked position, then to unlocked, and power up your unit. Chances are that the carriage was not dislocated when trying to move while locked, and will start to operate.
If it's not that, it may be a number of things, like broken belt, encoder strip (if any), carriage motor fault - things you won't be able to repair yourself.

the L1-00 indicate the scanner carriage is not moving. Something is stopping it. Open the document feeder and turn the copier on while watching the scan carriage (beneath the main glass) - does it move or try to move ? does it make a noise?
If it seems to be moving freely for a bit and then stop - is it going back to its "home" position (starting point). Remove the main glass and then move the scan carriage by hand (with the copier turned off) .. does the carriage move ok? check for a loose carriage drive wire or debris or something broken. Make sure the carriage locking screw is not holding it. Then turn the copier back on and see if the carriage makes an attempt to move back to its starting point. if everything seems to be moving ok then the problem could ly with the "home position" sensor. It could also possibly be a bad drive motor.

Try lubricating the lock lever with a drop of Marvel Mystery oil.It should slide from front to rear

1. Reset your All in One product:
2. • Remove the power supply for ten seconds and then, reinsert the power cord and turn on the printer again.
   • Print a basic self test page.
3. Clean the paper path:
   • Take a look inside the printer to determine the side on which the carriage is located (left or right).
   • If situated on the right, make sure there is no obstruction and then, move the carriage all the way to the left side.
   • If situated on the left, make sure there is no obstruction and then, move carriage all the way to the right side.
   • If located in the middle, ensure there are no obstructions. Then, move the carriage first all the way in one direction and then all the way to the opposite direction. Please do not apply too much pressure.
   • Remove the rear access door from the back of your unit. Check for and remove any paper still in the printer.
   • Replace the rear access door and close your unit top cover.
   • Re-connect the power cable only. If the unit does not automatically turn on, press the Power button.
   • If the Power light is on and steady, print a self test page.
4. Plug your All in One product directly into another power outlet:
   • Remove the unit power cable from any power strip or surge protectors and plug it directly into a grounded wall outlet
   • Try printing again.

Before you try this, put a couple of drops of resin-free oil such as 3 In One (sewing machine oil) or a tiny bit of penetrating lube on the shiny rod on which the carriage rides.
The original lube may have either dried out or has turned into a paste-lube gunk that is making the carriage hard to move.

If the 'rubber band' has teeth on the inside, it is the printhead drive belt and it may be stripped.
If the printhead centers for cartridge changes when opening a cover, let it center, pull the power cord out of the wall and carefully attempt to move the carriage by hand.
If you hear a similar noise, then the belt is stripped and will have to be replaced.
I'm not familiar with your model so can't advise if this is a do-it-yourself job or not.
