To Seal Or Not To Seal

Written by Barry Shultz


I get many emails from people with refilling problems and one ofrepparttar biggest is cartridges that just won't print after refilling them. There are many reasons for this but one problem in particular has been popping up with frequency lately. People are sealing cartridges that must not be sealed in order for them to work properly, or at all for that matter.

If you are ever in question as to weather to sealrepparttar 107182 refilling holes on your cartridge here are some tips. Ifrepparttar 107183 refilling hole is onrepparttar 107184 bottom ofrepparttar 107185 cartridge you better seal it because if you don't it will obviously leak inside your printer. In these casesrepparttar 107186 breather holes onrepparttar 107187 top ofrepparttar 107188 cartridge have not been disturbed so it should work properly if no other problems exist.

Ifrepparttar 107189 cartridge is a Canon BCI-3e or BCI-6 you better seal it and seal it good! For some reason these cartridges must have an air tight seal over any refilling hole orrepparttar 107190 ink will completely drain out ofrepparttar 107191 ink port that feedsrepparttar 107192 ink into your printer which causes quite a mess. These seem to defy physics. A dab of hot glue works well for these cartridges andrepparttar 107193 "dimple" of glue comes off easily with your fingernail when you want to refill again.

Cartridges that should NOT be sealed are all HP color cartridges. In particular isrepparttar 107194 C6578. This cartridge is deceptive because when you refill you are instructed to punchrepparttar 107195 little plugs in that are onrepparttar 107196 top ofrepparttar 107197 cartridge. While these plugs may look to be completely sealed they are not. A close inspection will reveal that these plugs are actually vented. So people looking to restorerepparttar 107198 cartridge to its original condition will seal these holes. Bad move,repparttar 107199 result is vapor lock and no print.

Emerging Printer Interfaces

Written by Barry Shultz


There are some new and exciting technologies for printers that we will all be enjoying inrepparttar very near future. Actuallyrepparttar 107181 technology is available right now but many people do not understand it or know how to use it.

The technology that I will focus on here is IrDA and Bluetooth interfaces. Gone will berepparttar 107182 wires which extends a lot of possibilities for placing your printer in your home or office.

IrDA is an acronym for Infrared Data Association. IR devices work by using infrared technology, and hence don't require any cables to connect them torepparttar 107183 printer. Actually this is old technology revisited. It was used widely in TV remote controls. IrDA will be replaced by Bluetooth eventually because of it's restrictions.

Using such printers, one can print directly from a mobile device, such as a PDA, cell phone or even a video camera, which supports an IrDA interface withoutrepparttar 107184 need of any cables or even a PC. The only shortcoming isrepparttar 107185 line of sight restriction. Asrepparttar 107186 devices work using infrared rays, any obstacles betweenrepparttar 107187 communicating devices will blockrepparttar 107188 signal.

Some HP printers with IrDA support are HP DeskJet 340, HP LaserJet 5MP, HP LaserJet 6MP, HP 2100M and HP4050N.

Bluetooth is another addition torepparttar 107189 new interfaces available for printers. Bluetooth is a low-cost, low-power, wireless radio frequency technology that allows various devices to communicate with each other.

These devices operate inrepparttar 107190 2.4 GHz ISM (industrial, scientific, medical) band. An advantage of Bluetooth over IrDA is that close proximity betweenrepparttar 107191 communicating devices is not required and distances of up to 40 feet are allowed. Also, Bluetooth does not suffer from any line of sight restrictions.
