How Can I Add Ink to "non-Refillable" Stamps - such as PLUS Privacy ID Guard Roller Stamps

This tutorial is to refill the "non-refillable" roller stamps made by "PLUS Guard Your ID". It is not for a refillable roller stamp which has.a refill hole in the middle of the roller.

The Plus Stamp non-refillable has a removable cartridge. The cartridge is not refillable and will cost $8. If you cut the stamp core open. You can see there is a sponge cylinder. A layer of rubber covers the sponge.

How to Unclog a Printhead

Some common problems in printers are indicative of print head clogging.  If you are experiencing a decrease in print quality, missing lines or blank pages while trying to print, this may be the issue.  There are many tips on the internet about unclogging the print head.  Such tips range from helpful to detrimental for the printer.  Today, I describe the unclogging process from an ink supplier’s perspective and hope it will be helpful to household users.

The mechanics behind clogging are simple.  The print head is like a water tank with a very tiny opening.  During printing, the machine squeezes out microscopic (picoliter) ink droplets.  The ink is designed to dry fast so as not to smudge. 

These are some possible reasons for clogging:

  • If the print head is exposed to the air for a long period of time, ink can dry up and block the small opening.
  • Foreign objects (ink impurity or dust) can block the opening.  Some internet instructions advise users to wipe clean the print head with tissues or paper towels, which may introduce blockage to the print head.  
  • An air bubble can temporarily block the opening.  Air is naturally dissolved in the ink. 
    • Fluctuation of room temperature will change the air concentration and thus form air bubbles. 
    • Changing cartridges also introduces air into the system.  (*Note: This is why you should do a print head-cleaning cycle after installing a new cartridge). 
  • It may not be a blockage.  There are processes that can permanently damage the nozzle; the print head may be scratched and damaged, the print head may have over-heated during a long printing process, or a paper jam may have caused the issue. 

Will a Refilled Cartridge or CIS System Void My Printer Warranty?

Will a Refilled Cartridge or CIS System Void My Printer Warranty?
In today’s fast-paced world in technology and entertainment, the trend toward high-quality printing is growing astronomically. With the high cost of original manufacture’s ink cartridges (OEM), home-refill cartridges evolved. Another mode of inexpensive ink manufacturing by third-party companies is the Continuous Ink Supply (CIS) System. This method feeds ink directly into the cartridge, eliminating the need for changing cartridges. The customer can save 30-40% by refilling old cartridges, and a BCH CIS System saves 80-90% in printing expense! Printer manufacturers do not recommend the use of these alternative ink solutions and even condemn them as unreliable and potentially damaging to the printer. It could be true for some inferior systems, but a well-designed CIS system can improve printer performance by eliminating air ingress, maintaining constant pressure and reducing the need of print head cleaning.
