Sealing Solution is applied to the cartridge printhead before taping or inserting in clip. The solution displaces ink in the printhead, maintains moisture and ejects cleanly when installed in the customer printer. Do you need printhead sealing solution? Distilled or DeIonized water (like the water you get out of your Reverse Osmosis unit installed at your shop) will work but this stuff works better. It has a few ingredients like Propylene Glycol in it which makes it "like" water. Chemists call it Hygroscopic for it's ability to attract and hold water, this keeps your printhead, already contaminated with ink, from drying out. Can your customer "I just opened this cartridge and it doesn't work" really fast ten times?

Nothinng will return a cartridge with a burned printhead to service. But this printhead cleaner used in a heated ultrasonic tank will dissolve dried pigmented black inks returning printheads to service without damage to the electronics. Paying your cartridge kid for 30 minuted to get an old Lexmark 16 to work doesn't make monetary sense. Total disassembly, cleaning and refilling is not nessescary for many "fresh" cartridges and it too wastes your technician's time. But some nozzles are almost always clogged. Exposing the printhead for 10 seconds in your heated ultrasonic water with this solution added will break down the cloggs and return a good printhead to full performance rapidly. Do you need ultrasonic tanks? No, you need heated unltrasonic tanks.

You push the plugs in to a HP "Pork Chop" cartridge to gain access to the sponge medium for refilling. You replace the plugs afterward to keep debris out and properly ventilate the chamber. Why ventilate? Because, if the plug doesn't leak air, a vacuum will result in the ink chamber causeing it to stop delivering ink long before the ink is expended. Your customer says "it worked fine for three pages then the yellow quit". Or they say "I hate you and you ruined my zen and I want my money back you toad". Or they say.. These plugs fit OEM fill holes and vent properly.

You are using hot glue to put top caps back on, right? This hot glue has a working time of 30 seconds, bonds well to plastic cartridges, is easy to reheat for additional cycles. We use them to plug the drill holes in HP 564/920, Canon 221, Lex and Dell top caps and even HP 88 types. It's the fastest, cheapest way to fill holes and bond in an ink shop. The best hot glue gun? It doesn't matter, find a cheap one or get a used one off of Craigslist. Call $10 the limit. Get a full sized one with a trigger. If there are two and one is pretty, take the pretty one.

You are cleaning your cartridge contacts, right? To avoid mid cycle failures you have to. The contacts on cartridges generally degrade over time because the copper and tin oxidize making a high electrical resistance barrier. Windex will clean them (and etch them) but you should finish a contact cleaning with a non-corrosive contact cleaner. It also removes sticker goo and upgrades the presentation of your products. P.S. Sell it to your customers so they have something to clean the contacts inside thier printers. When you sell it to them, advise them not to use Q Tips, they leave cotton fibres behind that can cause contact issues.
