My Cross pen fell on the floor and won't work

If answer 1 fails the pen can be returned to Cross for repair at no cost to you.

Pull up the top of the pen (with the clip). Remove the refill cartridge and examine it. If it is not damaged put it back in and fasten it in place by twisting. The cartridge comes with a colored plastic top. The cartridge must be inserted with the plastic on.That top must not be removed.

Did you get an answer to this as my Swarovski pen is doing the same?

The cross feed drive shaft is connected to the cross feed spindle via a coupling that resembles a universal joint that is threaded onto the end of the cross feed spindle. Either one of the roll pin holes in the drive shaft coupling has worn and the roll pin fell out or it has broken, or the coupling could have came un-screwed from the cross feed spindle. Remove the 4 bolts that hold the cross feed gearbox on and slowly pull it away from the machine and you should see the coupling I'm describing. My guess is that the roll pin broke or fell out due to wear. You can buy a new drive shaft and coupling or drill and install the next larger roll pin. Either way you should download a parts list for your machine. Just search for it, they can be downloaded free.

This pen will only work with GTCO SLX or Cordles Roll-Up products.
Install a new battery and it should work on a SLX cordless tablet or a Cordless Roll-Up.

There are a couple reasons a pen refill won't start writing right away. The first thing to check is the tip--often there is a bit of glue or plastic over it in order to prevent leaking.
If that doesn't work, then try one (or both) of the following two methods:
1) Place the refill (but not the tip) in some warm water. Heat will allow the liquid in the gel pen to become thinner and flow more naturally.
2) Hook a rubber band around the middle of the pen, using tape to ensure safety, and wind the pen while holding the rubber band on either side of the pen. Make sure the cap is on the pen. When the rubber band is tight, when you pull straight out on the rubber band from both sides of the pen, it should spin very quickly. The centripetal force will cause the liquid in the pen (at least half of it) to move toward the tip.
Make sure you fasten the rubber band to the pen with tape or something similar; otherwise the pen may go flying off at someone nearby. Also, again, make sure the cap is on to prevent any ink spraying out--this is unlikely in a gel pen, but it could happen.

Try hitting the pen head into your hand 5 times. Do the same with the eraser ( do it pretty hard but not too hard. I hurt my hand with the pen tip a LITTLE so you can gauge it by that). The humidity in the air causes the pen pressure to stick apparently. I had the same problem and this made it work. You should try and clean it too but if you don't want to take the pen apart this is the way to go. i hope this helps.

In settings, turn Tip Feel all the way to maximum Firm.
Does this help?

I got the same problem and have just solved it. I disassembled the pen and removed plastic sting that connects eraser cap and sensor (I've found that it fell down and stuck in the "click mode" when the pen was held upwards). Then reassembled it successfully. The eraser won't work, but you will get a spare sting instead :)
