How to use Google to search over multiple sites

Google has a lot of useful advanced search features.  One of them is the site: filter, which allows you to specify a specific website or domain to limit your search to.  Conversely, you can use -site: to exclude certain sites from your search results.

You can also use the :site filter to search over multiple domains or sites.  The OR operator is used when you want to do that.  For example, to search for "ducks" on Facebook and Twitter, you could type a query like this one:
ducks OR
And you would get results similar to this:

You can combine the site: filter with other filters (allintext:, filetype:, etc.) to narrow the scope of your search even further.

How to fix an SC400 error on a Ricoh Aficio SP C430DN printer

On a Ricoh C430DN printer, an SC400 error is often caused by a dirty image density (ID) sensor.  You can clean this sensor yourself, rather than pay a technician to come out and do it.  A dirty ID sensor can also cause other problems, such as color misalignment issues.

The ID sensor on this printer is actually a set of five sensors, located on the ID sensor board.  The ID sensor board is located inside the front door of the C430DN. You can see a picture of it in the service manual, on pages 4-48 and 4-49. (If you don't have the service manual, you can probably find it online -- such as on -- but always be careful when viewing or downloading documents from unfamiliar sites.) The manual shows you the procedure for removing the ID sensor board; you don't need to do all of those steps just to clean it.  Follow the steps shown until you are comfortable seeing or reaching the ID sensors so you can clean them.

If you can get to the sensors, you can wipe them down with a dry, lint-free cloth.  You can use a tiny bit of alcohol to clean them, but make sure you wipe off every last drop.  If you can't physically reach the sensors, use canned air to clean them.  Be sure to clean all five sensors.  Don't use an oil rag or a cleaning wipe to clean the sensors, as these can leave a residue.

Often, cleaning the ID sensors and rebooting the printer will resolve an SC400 error.  If the problem persists, however, it may be time to call a technician to diagnose it.  You may need to replace the ID sensor board, or you could have a problem with the transfer belt unit or another internal component.

How to prevent Twitter from posting your location when you tweet

By using location services with a Twitter mobile app, you may be allowing Twitter to post your location under your tweets.  At the bottom of your tweets, if you see "from" and a location next to the date and time of your tweet, then at some point you gave Twitter permission to post your location.

To prevent Twitter from adding your location to your tweets, follow these steps:

- In your web browser, click on your avatar in the upper right corner (next to the "Tweet" button).
- From the drop down menu, select "Settings and privacy."
- On the left side of the screen, select "Privacy and safety."
- To the right of "Tweet location," uncheck the box next to "Add a location to my Tweets."
- Click the "Save changes" button at the bottom of the screen.
- Enter your Twitter password in the text field.
- Click on "Save changes."

If you'd also like Twitter to remove your location from any tweets it has already been included in, click the "Delete location information" button below the location checkbox, then click "OK" when prompted to confirm your choice.
