Max Professional 2145 Rubber Rejuvenator - 10 oz.,Black and Silver

It works - saved my printer. Apparently, printers are subject to dirty and/or dried out rollers which causes the printer to jam. In my case the printer - a Brother MFC 7340 - became totally unusable. Paper which previously jammed sometimes was not jamming every time - could no longer print out anything. I was not thrilled at the prospect of scrapping an otherwise good machine and shelling out for a new one. Probably a whole lot of this problem was my fault in the first place for continually using the back side of paper after I no longer needed what was on the front side. I read the reviews and instructions and thought, what the heck....I'll give it a try. It comes with a long red nozzle to allow you to pin point the product deep into the machine and directly on the rollers. I removed the drum and toner cartridge so as to expose the rollers in the front of the machine. They were literally black and covered with ink. I squirted some of the product - using the nozzle - directly on the roller, let it sit for a few seconds to soak in, then wiped the roller with a 2x2 cotton square - all the black ink came off. The roller was bright white underneath. Next, I manually rolled it forward, exposing the next portion of the roller and repeated the process until the entire roller was cleaned. You can only access one small area if the roller at a time so it takes several steps to clean the entire roller. You have to keep pushing the roller forward exposing each section until you have cleaned the entire roller. I then repeated it on the other side, replaced the cartridge and plugged the machine back in. It is very important that you unplug the machine before doing this cleaning - the fluid is flammable and, worse, you don't want to get a shock or cause an spark to arc while working on the machine. I then tried to print and it worked perfectly! Well worth the small price to purchase this product in order to save the printer. This bottle just saved me the cost of a new printer. When you store your bottle of product, be sure to put two strong elastic bands to secure the red long nozzle which will easily otherwise get lost.

Printer wouldn't auto feed until I used this product.

Used on my printer rollers, which were not feeding paper correctly. Used a small amount of the product, allowed it to sit overnight and the next day it worked like new. Very satisfied with results, shipping was prompt. Wish a smaller size was available!

I used to repair VCR(old style video tape recorder) before which uses pinch rollers and belt extensively. This stuff really helps to restore the gripping power of the rubber pinch rollers if you know what you doing. From my experiences, while some machines will work by just spraying on the rollers only, most machines will need extra steps to make it work and make the repair last a lot longer. Toners and inks tend to build up on the rollers thru time. If the build-up is not too much, spraying on the rollers directly alone may temporarily solve the problem but if the build-up is too extensive, the roller needs to be cleaned thoroughly to really make it work. To clean the rollers manually, you need Q-Tips and optional cleanroom wipes or any lint-free cloth. To do so: 1. Pre-Treat The Rollers with the Rubber Rejuvenators: Spray the rejuvenator on the rollers (try not to get on the other plastic parts), let it sit for a minute. 2. Clean The Roller With Q-Tip: Spray the rejuvenator on to the roller again and also the Q-Tip and rub the Q-Tip across the width of the roller in a back-and-forth motion. The Q-Tip should become dirty (usually black) as you clean it. Make sure you clean the entire surface of the roller until almost no black residue discoloring the Q-Tip. 3. Repeat Step 1 & 2 on Other Rollers 4. Make sure that you clean all rollers in the paper path.

I use it to refurbish cassette tape players, I apply it with a cotton swap

Not bad

Update to previous review.. The cover cap has been strengthened, at least on this past order. Great improvement on the cap. Thanks Hello, as far as the chemical product, it is great. I just have problems with the packaging. The top lid appears to come off to easily and then the spray applicator breaks off. And you don't want to try to put the sprayer back on. The can will empty out and the chemical is strong smelling. Outside of that.. this stuff is great!!

It doesn't help, caused damage and NOW a replacement printer is necessary. Rubber rejuvenator states ALL machines. This stuff is horrible and you will be worse off than when you started. Absolutely unbelievable.

We use this for our commercial printer. Often the rubber advance will pull too many sheets in at once, or simply get stuck. This little printer hack has saved us from throwing the printer out the window!

Restored pick up rollers on my printer to an as new condition.

Perfect

Good Product.
