Ever wanted to know how big boys make remanufactured inkjet cartridges? Read on and I'll give you a quick outline of what you actually get when you buy a remanufactured inkjet cartridge.The first thing to realize is that refillers, or Remanufacturers only remanufacture inkjet cartridges that contain a print head. Those include Hewlett Packard and Lexmark. All others are variations of aforementioned cartridges. This is because generic or compatible cartridges for others, Canon, Epson etc., are very cheap and they could not make a profit by remanufacturing them.
Step 1. The Empties Search.
In order to remanufacture an inkjet cartridge you must first have empty one to refill. When a new printer using a new cartridge is introduced it may take several months if not years for empty cartridges to become available in quantity that warrants refiller to make investment to tool up for remanufacture. As of this date a very popular HP cartridge that was on market for over a year is still very scarce as remanufactured. A very popular Lexmark cartridge, 12A1970 cartridge is almost impossible to locate because Lexmark is buying them back, but these are articles unto themselves.
The inkjet cartridge remanufacturer carefully inspects cartridges for blemishes and for evidence that is has been previously refilled. They must be "virgin" cartridges (never refilled) or they won't get refilled. (By most scrupulous remanufactures) Next cartridges are electrically tested using sophisticated electronic equipment that tests print heads and related electronics. This will be a 100% pass/fail test. No in betweens here. Anything under 100% gets tossed.
Step 2. Cleaning.
Each cartridge is cleaned ultrasonically inside and out. All remaining ink is thoroughly flushed from cartridge and they are bathed in a cleaning solvent. Step 3. Refilling.
Here is where to pros are separated from hobbyist. To properly refill a cartridge there must be a measurable balance between ink flow, vacuum and pressure. Very expensive refilling machines are needed to accomplish this task properly. The machine will have capacity to refill many cartridges at same time. The cartridges get snapped in place and when all gizmos are set properly they all get filled at same time.
