I have successfully used the Penny Method to create a hot glue plug.

You say What is the penny method?

Please read below for the answer.

The Penny Method is the method by which an American coin (a penny) is used to flatten a glob of glue over a top fill hole. One benefit in using the coin is that the thickness of the cap is less than 1/32. This is very important if you have a clearance problem with your carts and your printers case. The case can grab the carts plug and pull the plug from the cart (the top fill method is being used in this scenario).

I decided to try the Penny Method because I found that using my finger was messy and gave mixed results.

Here are the details:

Before I used the Penny Method I practice on a lid of a food container. My glue gun has two temperature settingslow and high. I placed globs of glue on the lid using the low setting and the high setting. After placing the glob of glue on the lid I placed the penny on the glob and pressed down on the glob. After a minute I pulled-up the penny to find a circular piece of glue. The glue was no more than 1/32 thick.

I flatten a number of glue globs. The temperature of the glue made little difference in the success of creating the glue plugs. The amount of effort to pull the penny from the glue glob was all over the place. The effort went from very little to medium effort. The degree of effort to pull the penny off the glue did not change the glue plug. The glue stayed in place and was difficult to pull from the plastic. This told me that the plug would not leak.

Note: I used the Penny Method on a cart before performing my experiments on the lid. I filled the cart and used the penny to flatten the glue plug. The plug did not leak. I was told by some people on this forum that my Penny Method would not work. This was said to me even after people were told of the success I had with the cart. Well, I thought that maybe the success I had with the cart was a fluke. I decided to experiment with the lid to see if my initial success was a fluke or not.

Even though the plug stayed in place no matter the effort it took to remove the penny I wanted to find a way to pull-up the penny with the least amount of effort. So, what to do? I decided I needed to use a releasing agent on the penny. I wondered what to use as a releasing agent. I decided to use petroleum jelly. I placed the jelly on the penny. It worked. It required very little effort to pull-up the penny. The very little effort told me that the glue plug would not be disturbed when pulling-up the penny and thus, the plug would give a good seal.

Even though at this point I was fairly sure that my Penny Method would work on a cart I decided to perform another experiment. I wanted to find a way to keep the glue from the fill hole. Most of the time removing the plug cap did not remove the glue in the fill hole. One had to dig out the glue which was very time consuming. I decided I needed to place a disk of material over the hole and placed the glue over the disk. So, what material to use? I decided to use a disk of inkjet paper. I had used a hole puncher on some inkjet paper and I used one of the resulting punched out disks to cover the fill hole.

When experimenting with the paper disk I found that I first had to put down a small amount of glue next to the fill hole. Next, with a pair of tweezers I place the paper disk on the glue and pressed down on the disk. I had found that placing glue on the unglued disk would not work. The disk would not stay over the hole. With a glued down disk I could place glue over the disk and the disk would stay over the hole.

At this point I had everything I needed to successfully use the Penny Method. I had learned that the penny would give me a nice flattened-out glue disk. The penny only required very little effort to be pulled from the glue disk. And last, the paper disk would keep the glue from entering the fill hole. I was ready to use the Penny Method on a cart.

I pulled a PGI-220BK cart from my PIXMA MX870 printer. The cart had 1/8 of ink in the ink reservoir. I replaced the cart with a virgin OEM Canon cart. The virgin cart was getting old and I thought it was best to use the cart before the virgin cart was unusable.

The pulled cart had a 5/32 fill hole. I removed the hot glue plug from the hole. I removed all signs of glue in the fill hole and around the fill hole. I made sure that area around the hole was smooth and clean.

With the hole cleaned I glued a paper disk over the fill hole. With this done I placed a glob of glue over the disk and I pressed the penny down on the glue. I waited for a minute or two and pulled-up the penny. I looked to see what had happened. I saw a nice glue disk with the paper disk being completely covered by the glue disknice and neat.

Note: The size of the glob if made into a ball should be somewhere around 3/16 dia. to 7/32dia. If you do not have a clearance problem the ball dia. could be as large as dia.

Next, I turned the cart upside down to test for leakage. I waited for fifteen (15) minutes and turned the cart right side up. I then touched a tissue to the glue plug to see if there were any signs of ink leakagethere were none. I did this test two more times. I saw no leakage.

With no leakage I believe the Penny Method was a success. Now, some of you may have spotted the fact that I did not fill the cart. This was on purpose. The ink that was in the cart was enough I believed to tell me if the glue plug would leak. You may disagree. I had another reason to not fill the cart. I decided that the cart was not to be placed back into the printer, but was to be placed into long time storage. In my thinking a filled cart is one that will leak. A cart that was not filled would have a better chance not to leak than one that was filled.

ATTENTION: I have a question to the naysayers, Do you still believe that the Penny Method does not work?

Below are pictures (with notes) I took when I performed the Penny Method:

1. This is a picture of my glue gun. The brand name is Ad tech. It has two heat settingslow and high. The low is 140 F and high is 210 F. Please use the temperatures as reference only. The model number is 401. I believe I bought the gun at Sears. IMG 2512 My hot glue gun

2. These are pictures (front and back) of the glue stick package. Ad tech makes the glue sticks. I believe I bought the gluesticks at Sears. The front of the package says the following: NON-YELLOWING, FULL SIZE, Multie@Temp, 24 GLUESTICKS, BONDS WOOD, METAL, GLASS, FLORALS, FABRIC AND FOAM IN 20 SECONDS!

Here is some information on the back of the package:

3. This picture shows the glue plug with the penny next (for scale) to it. The plug is approximately 7/16 in diameter. You can see the paper disk under the glue plug. The marks on the paper disk is printing from the sheet that was hole punched.

4. This picture is a side view of the cart that shows the penny next to the glue plug. The thickness of the plug is less than 1/32.
