1. Avoid The Ink To Get Exposed: Whether your printer is on or off, the ink cartridges are still exposed to oxygen once opened which causes them to dry out. Thought the standby mode keeps the cartridges as air tight as possible but it is recommended to turn it off. Also unplugging the printer without powering leaves HP refills exposed to more air and eventually damages the print-heads.

2. Maintenance: In order to keep nozzles clear, you have to go through the process of the recharge cycle the printer performs. You have to burn through ink and they are mostly found online on the name of re-manufactured inks and it is great. A command causes ink to be heated and forced through the print nozzle and onto the paper. It can help you save money as well.

3. Cartridge Not Recognized: Ink and dust can accumulate over time, blocking good contact with the printer. The strip and the contacts on a typical print cartridge are made out of copper. You will notice that the copper oxidation will be removed by the eraser and the contacts will turn golden color.

4. Lubricate Print-Heads: It is not such a tough task to lubricate the print-head assembly’s track once in a while. You should look for the shiny steel rod that the assembly’s mounted on and not the plastic ribbon. You should even avoid touching any of the ribbons if you can. Just smear the rod really thinly on all sides with petroleum jelly with a very thin layering. Move the print-head assembly back and forth a few times afterward to lubricate the inside.

5. Do Not Buy A Printer With Separate Print Heads: Since most people are not buying industrial strength HP refills, replaceable print heads are available with printers, thus, the print heads sediment up. Now, the only way of fixing it is to throw the printer away. This process is absolute waste of money and resource when you find out your multifunction scanner/fax/printer goes useless because of this.
