HP 56 and 57 cartridges
After filling these carts, is it necessary to cover the holes with tape?
New carts have a label over the holes without any venting. Some suppliers of ink say covering them with scotch tape is not necessary, others say to cover them with tape, others say be sure to punch a pin hole for venting. -- Dave C. Remove the five 9's (leave the 4) for email. |

I reuse the same label, so far I've used 3 labels about 8 or 9 times, but they
are beginning to lose their stickiness. There is venting via the narrow grooves under the label, which is why I prefer to keep a label in place after a refill, and I'm careful to align it properly to restore the same venting. A lot of refill ink suppliers say that the label can be left off though, but it doesn't seem right to me, and must make the ink more prone to drying out in the sponge. "Dave C." wrote in message ...

The holes vent from under the label through molded channels. They can be
left safely uncovered. The labels are designed to hide the availability of fill ports for the cartridges, while still allowing the cartridge maintain ambient pressure.
