Question: I am considering an ink refill kit for the Canon MP620 printer, which includes multiple bottles of both color and black inks. This printer has a mix of smaller CLI cartridges and a larger PGI-220 black cartridge. Can you confirm if the PGI-220 cartridge uses pigment ink? Is it advisable to use dye ink in this pigment cartridge? Also, does pigment ink offer better water resistance for shipping labels? For another printer we own, the HP Deskjet 940C, does it require different inks compared to the Canon, or can they use the same inks? Lastly, which type of ink is less likely to clog if printing is not frequent?

1. Ink Type in Canon PGI-220 Cartridge: The larger black cartridge in your Canon MP620, marked as PGI-220, indeed contains pigment ink. Canon labels pigment ink cartridges with "PG" or "PGI" and dye ink cartridges with "CL" or "CLI."
2. Using Dye Ink in Pigment Cartridges: There is no problem to use dye black ink in the pigment (PG/PGI) cartridges.
3. Water Resistance of Pigment Ink: Yes, pigment ink is typically more water-resistant when dry compared to dye ink, which can be particularly beneficial for printing shipping labels that may be exposed to moisture. This resistance can reduce the necessity for additional protective measures like packaging tape over the labels.
4. Interchangeability of Inks Between Canon and HP Printers: The inks between your Canon and HP printers can generally be used interchangeably for the black ink. However, make sure to use the appropriate tools and follow refill instructions specific to each cartridge model to ensure optimal performance.For MP620, you will need a set of refillable cartridges. These cartridges can be found on eBay by searching "refillable cartridge MP620". We do not sell cartridges. For HP deskjet 940C, the HP 45 cartridges can be refilled with kit https://bchtechnologies.com/pigment-ink-refill-kit-for-hp-black-15-c6615d-40-51640-45-51645-cartridges/ The two black inks are pigment. However, if you want to use dye ink, you can use the same dye ink you use in the 6-pack for Canon https://bchtechnologies.com/standard-600-ml-4-color-refill-ink-for-canon-kd600x-cc/, and buy a priming tool separately: https://bchtechnologies.com/priming-clip-for-hp-15-40-45-c8842a-45si-cg339a-51645a/ For HP 78 tri color cartridge, you will need this priming tool: https://bchtechnologies.com/priming-clip-for-hp-17-23-41-78-tri-color-cartridges/ and use the same ink as the six pack
5. Ink Susceptibility to Clogging: Pigment ink is more prone to clogging compared to dye ink, primarily due to its larger particle size. This can be a concern for printers that are not used regularly. To mitigate this, it's advisable to perform occasional cleaning cycles and print tests to keep the ink flowing and prevent the nozzles from drying out.

Addressing printer issues can be intricate due to the hands-on nature of the problems. For instance, resolving a simple clog might involve advice on unclogging procedures. Conversely, if the printer was inactive for an extended period, a thorough service for the ink system might be necessary. Paper jams can originate from numerous causes, and solving such issues is a common in-office jest.
