Make HP printer think there is a new catridge after catridge refill

I read this information:

While a Hewlett Packard (HP) inkjet cartridge can be refilled easily, getting it to work again in the printer is another matter. The contacts on the back of the cartridge are programmed to read the ink level, but they don't reset for the printer just because you add more ink. You must get the printer to recognize the cartridge as new. You can do this easily if you have two other old cartridges, or you can manipulate the contacts on the refilled cartridge.

Difficulty: Moderate

Instructions

Things You'll Need:

• Adhesive tape

1. Insert the cartridge you refilled into the HP printer. Have the printer print an alignment page, thus recognizing the cartridge. The printer will still read the ink level as where it was before you refilled it.
   
2. Remove the cartridge from the printer and replace it with another old cartridge. Have the printer print an alignment page with this cartridge so it recognizes it as a different cartridge from the first one.
   
3. Replace the second cartridge with a third one and run the same alignment page. Because the printer only retains the memory of two print cartridges, it will erase the memory of the first (refilled) cartridge.
   
4. Insert the refilled cartridge into the printer. The printer will now recognize the cartridge as being full.

1.  Second option:
    1
   Tape over the contact squares on the top left corner of the cartridge's contacts. Insert the cartridge into the printer and run an alignment page. Ignore any messages that might appear saying there is a problem with the cartridge.
   
2. 
   
   Take the cartridge out of the printer. Remove the tape from the left corner and tape over the contact squares on the top right corner. Place the cartridge back in and run another alignment page.
   
3. 
   
   Remove and reinsert the cartridge, this time with no tape on any of the contacts. Check to see if the printer recognizes the cartridge as being full.
   
4. 
   
   Repeat the above steps if the cartridge is still shown as being empty. This time, use the bottom corner contact squares instead of the top ones. If you are still unable to reset the cartridges, using multiple cartridges is likely the only way to do it.

In my case, I only have two cartridges, so I did a combination of both techniques. I put the old one (without ink), then the same one covering some of the contacts with tape, then again the same one, covering other contacts... finally the refilled cartridge... and it seems to be working!

By the way, I have an HP Deskjet F4185

Scan and send a signed contract as PDF

After signing the contract, you scan the pages, and each of them will come to you as jpeg (or some other format) image file.

Then, print to pdf each of these images. Now, you have a bunch of PDF files.

If you have ubuntu, then you can merge the pdf files into one, using these instructions:

http://ubuntuhowtos.com/howtos/merge_pdf_files

First of all you will need the program called pdftk. You can get it by opening terminal and typing:

sudo apt-get install pdftk

Now you can merge pdf files by putting them in the same directory and typing:

pdftk 1.pdf 2.pdf 3.pdf cat output merged.pdf

or if you wish to merge files in alphabetical order you can simply type:

pdftk *.pdf cat output merged.pdf

If you use this last command, make sure you don't have any other files there in pdf format which you don't want to be merged with your contract (or any other document, of course).

Garbage bin staining the wall

Our garbage bin had been for the past few years staining the wall behind it because every time somebody tried opening it with the foot, it was pushed backwards and would make contact with the white wall behind it. We had somehow got used to live with the fact of that big stain on the wall.

We have painted recently, and I decided to do something about this stain so that it wouldn't appear again. Here is what we did: we put two door stoppers at the bottom back of the bin.

First we cut two rectangular pieces of wood.

(Hmmm... the floaters instead of shoes... I guess we need to improve in safety at work)

We placed these pieces of wood inside the bin, at the back, i.e. behind the points where the stoppers will go.

Then we drilled two holes of the respective size for the screws, going from outside, through the bin and reaching the wood. As you can imagine, the wood is to give strength for holding the screws that will hold the stoppers.

Finally, of course, we screwed the stoppers, and viola, the bin doesn't touch the wall, unless you really force it to!

Automatic Word Completion Problems with OpenOffice.org

I was having problems with the word completion while working on the translation of a large manual. I thought it was a problem that the word completion was not working properly, so I searched for how to switch it off... and this is what I found:

How do you turn off the automatic word completion behavior?

1. Open a text document.
2. From the pulldown menus, select Tools > AutoCorrect Options.
3. Select the Word Completion tab.
4. Deselect the check box to the left of "Enable word completion".
5. Click OK.

1. For OpenOffice.org 3.2, open a text document.
2. From the pulldown menus, select Format > AutoCorrect > AutoCorrect Options.
3. Select the Word Completion tab.
4. Deselect the check box to the left of "Enable word completion".
5. Click OK. 

(from: http://wiki.services.openoffice.org/wiki/Documentation/FAQ/Writer/AutomaticFunctions/How_do_I_turn_off_automatic_word_completion%3F )

When I went to the settings, before turning it off, I decided to try deleting all the previous entries... they were several thousands I guess.

After deleting them, now is working much better, remembering new entries, thus guessing well and not giving me wrong guesses, that cause misspellings.
