Why using syringe is the best way to refill a cartridge?
Jul 26th
Peoples always ask me, why using syringe is a better approach when you refill a cartridge.
Simple reason, you take control. Let me explain.
When your printer “declare” the cartridge is empty, actually it is not totally empty. The printer “estimate” the ink level by calculating the ink consumed during printing. So, when you want to refill the cartridge, how do you know how much ink that you need to put into the cartridge?
The best practise of refilling cartridge is not to refill too much. This is one of the rules that I mentioned in Best practise of refilling cartridge page. If you refill too much, the ink inside the cartridge give the pressure to the print-head and you may get ink “blob” in your printout.
By using syringe, you control how much ink that you need to inject into the cartridge. Most HP cartridges inform you how much the ink contents inside the cartridge at their label, so you can inject up to the amount of ink mentioned in the label. Once again, don’t refill too much. You have to stop injecting the ink when you see the ink come out from the refill hole (suck a bit if necessary).
Some refill kit manufacturers don’t like to use syringe in their product for packaging reason. The syringe make the refill kit bulky, taken too much space in their packaging and less attractive appearance, etc.
What is air bubble?
May 12th
When you shake the cartridge, it may form air bubbles inside the cartridge.
Does it harms? It depends. The most critical is not to have air bubbles in the print head. Popular terms is air bubble trap. When you shake the cartridge, the air bubbles will form in the sponge. If this happen, just leave the cartridge overnight, the air bubble will goes up eventually.
If the print head have air bubbles then the quick solution is to perform head cleaning (instructed from your computer). The head cleaning is like flushing the ink into tiny hole inside the print-head. Of course, this will reduce some of ink in your cartridge.
If you can wait, don’t force it. Leave it overnight. Let the air bubble release themselves. If the problem still persists then you need to perform head cleaning.
Reset ink level for HP C6657A (HP57)
Mar 9th
Last month’s post, I have shown to you on how to reset ink level for HP 56 and HP 58. Today, I will show you on how to reset ink level for HP C6657A or HP 57.
Note: These procedure may not work for some printers. The printer simply refuse to print alignment page when you cover the contact with tape.
Put tape over Contact #1 as shown in the first picture above.
Put the cartridge back into the printer with the tape fixed on the cartridge.
The printer will print an alignment page. Once this has completed, continue with Step 3. If the printer does not print the alignment page then this procedure will not work for your printer.
After the printer has completed printing of the alignment page, open the cover, remove the cartridge and place a piece of tape over Contact #2 as shown in the second picture on the left.
Put the cartridge back into the printer. The printer will print another alignment page.
After this page has been printed, remove the cartridge from the printer, remove all tape from both Contact #1 and #2.
Reinsert the cartridge back into the printer. Ink levels should read full now.
If the process does not work for you, make sure that no adhesive left stuck on the contacts of the cartridge. Any residue may cause the cartridge not to be recognized by the printer at all.
If you have cleaned the contacts with rubbing alcohol, go through steps 1-4 again, make sure each step is followed exactly.
