The black cartridge is empty, and the color cartridge is full, can it be filled directly?

It's best not to, take the color ink down, use it first, sometimes even the supply has to rely on the original ink cartridge to overhaul, leaving a good one only good and no harm. Remember to seal the ink outlet of the cartridge, otherwise it will leak, and in fact, it can't be left for too long, it will dry out.

Even the ink supply is still relatively easy to have problems, but you have bought it, then, what can be done at present is to always pay attention to maintenance, use the best continuous supply of ink, don't move the external ink tank, put it in the same place!

ps: Even if it's really broken, you dismantle all the things related to the offering, don't leave traces, take it to the repair point to repair, and don't admit to using the supply to death, just say that you use the original version, otherwise you won't repair it!

OK. HP's printer black is used separately from the color cartridge. You can start by switching to a black offering. When the colors are used up, they will be replaced with colors and used together. There are no other effects.

I heard that I can save a lot of money by filling ink, so I went to buy a bottle and came back, according to the instructions on the Internet step by step, there was no problem at first, and it was relatively smooth, but then somehow the ink mouth was blocked, and the ink began to seep outside, as a result, my hands, printer, desk, the ground was pitch black, and I couldn't wash it clean.

The last time I heard a colleague say that it is quite cost-effective to modify a continuous supply system for the printer, I went to change it, and it was really good to start using, I was still a little proud, who knows how long I was proud, the machine had a problem, the words that were typed out were deep and shallow, there would be no for a while, and a document had to be repeated many times. Later, I went to repair it, and when I opened it, there was ink splashed everywhere in the machine, and people said that the ink mouth was blocked, and it was caused by myself.

Those compatible ink is easy to block the ink port, note a few times the machine can not be used, get the after-sales people do not give repair, a machine thousands of dollars, other parts are fine, but it is broken the most valuable core component - the print head, this money is not saved, but I have found some trouble for myself, and I am not troubled!

The difference between even inkjet cartridges and ordinary ink cartridges is:1. The process is different

Even the inkjet cartridge is generally transformed from the ordinary printhead cartridge, and there is generally no sponge inside the inkjet cartridge, and the space for containing ink becomes very large, and more ink can be added at one time, and some air balancing devices are also used; The internal structure of ordinary ink cartridges has a sponge, and the ink cartridge relies on the sponge to carry the ink, and the sponge occupies a large part of the space, and the ink capacity is not very large.

2. The quality of the cartridge is different

Even the inkjet cartridge is generally a secondary transformation of the cartridge, and the internal sponge device is taken out, although ink can be added for recycling, but there is no sponge to absorb ink, and the ink leakage phenomenon on the way of the cartridge is more serious; Ordinary ink cartridges are generally brand new, and a sponge is used inside to carry the ink, so there is relatively little ink leakage.

Precautions for the use of inkjet cartridges:1. The bottom of the external ink cartridge needs to be kept on the same plane as the printer. That is, the printer and the outer cartridge need to be placed on the same desktop.

2. Do not easily plug and unplug the ink cartridge. Otherwise, it is easy to get into the cartridge air.

3. Do not easily clean the nozzle.

4. Do not disassemble the sprinkler head under any circumstances unless the sprinkler head is replaced.

5. Resolutely do not use syringes to pressurize the nozzle.
