Once I refilled the HP # 21 black cartridge, but after refilling it stopped printing. I tried to reanimate it by running the command "Printer Properties - Printing Preferences: Cleaning the Cartridge, Aligning, Printing a Test Page", but this did not work. In addition, for half a year the color cartridge HP No. 22 was lying idle, which also stopped working after refueling and, obviously, dried up. I tried to clean with steam, cologne - nothing helped. Subsequently, I still managed to restore the dried cartridge, and in just 1 minute.
Necessary
- - 1 ml insulin syringe;
- - cologne;
- - napkin.
Instructions
Step 1
You still need to soak the color cartridge in cologne. For this, a napkin was moistened (by no means a cotton pad!) And the cartridge was placed by the print head on the napkin for 5 minutes.
Step 2
Secondly, when refueling, the air still got into the syringe, since it was impossible to tighten the ink without sucking in air, so it was decided to draw out the air with the syringe (more precisely, draw out the air through the foam rubber nozzles with a needle!) Until the paint appears. While this did not help, it was likely aided by the recovery of the cartridge.
Step 3
And here's the secret! I took a syringe (no needle!) And started sucking air from the print head itself. In a minute, ink appeared, and it was possible to print and photocopy the image with red paint, and then black.
