Ricoh troubleshooting: How to fix a scan folder not found error

There are many possible reasons why you may not be able to scan to a folder from a Ricoh multifunction copier or scanner.  Here are some of the more common reasons:

- The folder that you are trying to scan to isn't shared.  Check the folder's share settings.

- The user account you are using to authenticate does not have rights to access that folder (possibly someone changed their password recently).  Update the password in the copier's address book (User Tools/Counter > System Settings > Administrator Tools > Address Book Management).

- There is a network connection problem somewhere between the copier and the computer.  Try to ping the copier from the computer and vice versa, then narrow down the problem by checking any intermediate devices (switches, hubs, routers, etc.).

- There is a hardware device or software program preventing the copier from reaching that folder (i.e. a firewall, anti-virus program, security suite, router, etc.).  Check any hardware/software security settings that may be preventing the connection.  You may have to set up an exception in your firewall.

- The copier and the computer are not in the same workgroup/domain.  Change the copier's workgroup or domain to match the computer you're trying to scan to.

- If you are using an IP address for the computer instead of a host name, the computer's IP address has changed.  Update the IP address, or change the destination path to use the computer's host name instead of IP address.

- If you are using the computer's host name in the scan folder path, either the host name may have been changed, the DNS record might be corrupted, or the DNS server might be down.  Confirm that the host name is correct, and if it still won't connect, replace the host name with the computer's IP address in the scan folder path.

- The copier's SMB protocol has been disabled (User Tools/Counter > System Settings > Interface Settings > Effective Protocols).

If scanning to a folder was never fully set up, you can find instructions for doing so here:

TrumpTalk Alexa skill

Love him or hate him, President Trump has said some outrageous things.  He's made ludicrous promises, tried to pass off many falsehoods as truth, and offended plenty of people.

Hear some of his greatest hits, as recited by Alexa.  Just say:
  • "Alexa, run the best words"
  • "Alexa, open the best words"
  • "Alexa, launch the best words"
 Alexa will pick a random Donald Trump quote from the TrumpTalk repertoire and recite it, with characteristic enthusiasm and passion.  The skill has 70+ Trump quotes to randomly choose from, with more added often.

How to get into service mode on a Ricoh Aficio copier or printer

NOTE: Before entering service mode, be very careful not to adjust any values that you are not familiar with.  You can take down the whole copier just by changing a few numbers or settings.  It's best to have a Ricoh-trained technician adjust any service mode settings.

For most modern Ricoh copiers (i.e. Aficio MP 6003):

To enter service mode, press the yellow Reset button, then 8-0-6-1-8-2.  Then hold down the red Clear/Stop button for about 5 seconds.  The screen will shift to a menu.  Select the first option in the menu: System/Copy SP Mode.

For most Ricoh copiers older than an "03" model (i.e. Aficio MP 4002):

To enter service mode, press the yellow Clear button, then 1-0-7.  Then hold down the red Stop button for about 5 seconds.  The screen will shift to a menu.  Select the first option in the menu: System/Copy SP Mode.

For most Ricoh printers without a number pad (i.e. SP 4310):

To enter service mode, hold down the up and down arrow buttons at the same time, for about 5 or 6 seconds, then release them and press the Enter button.

How to unsubscribe from all YouTube channels at once

Want to unsubscribe from all of your YouTube channel subscriptions at once?  Here's how.

1. Go to the YouTube subscription manager page.  (If you're not already logged in, you'll need to log in.)

2. Copy the code below and paste it into your browser's address bar.  Some browsers won't paste the javascript: part at the beginning; type it in if it doesn't copy over.

    var btns = document.getElementsByTagName('button');
    for (var i = 0; i < btns.length; i++) {
        if (btns[i].dataset.isSubscribed == "True") {
            if (!!btns[i].dataset.showUnsubConfirmDialog) {
                delete btns[i].dataset.showUnsubConfirmDialog;

3. Press Enter.

You will be unsubscribed from all channel subscriptions currently displayed on the screen.  No confirmation dialog box will be shown.  (Note that if you have channel subscriptions that are not currently displayed, they won't be removed.)

How to wipe an iPad

If you're planning to give or sell your iPad to someone else, it's a good idea to wipe all of your data off of it first.  Doing so is very easy.

  • Tap Settings
  • Tap General
  • Swipe down to the bottom of the menu and tap Reset
  • Tap Erase All Content and Settings
  • Tap Erase
  • Tap Erase again

If you just want to reset your iPad's settings back to their default values, but you don't want to delete any of your data, tap Reset All Settings instead of Erase All Content and Settings.  For the subsequent steps, select Reset rather than Erase.

How to reduce file size when scanning documents or images


When scanning a document, you can often get away with just placing the paper into the scanner and pressing Start.  However, if you scan a lot of documents, or if file size is an important factor, you'll probably want to check your settings to make sure you're not wasting disk space with bloated, unnecessarily large scan files.

Here are some things you can do to reduce the size of a document when scanning it into a computer or document storage system:

Scan in black and white

Unless you specifically need a color copy of the document, choose the option to scan in black and white.  Even if you are scanning a black and white document, make sure you check the color setting; a scanner set to scan in color may reproduce black on a page using multiple colors, which can make the file size significantly larger (often using 4 bits for every 1 that a black and white scan would use).

Some scanners will have an auto-select feature, which attempts to detect whether the document is black and white or color, and scan accordingly.  If you are scanning a stack of documents with only some in color, you may want to consider using this feature if it's available on your scanner.  It may be called Auto Color Select or something similar.

Reduce the resolution

Scanners typically measure resolution (the density of pixels) by dots per inch (DPI).  Lowering the DPI can drastically reduce the file size of a document.  For text-only documents, 200dpi is often sufficient.  For images or high-quality scans, you may want to use a higher number, like 400dpi.

Check your file type

The file type is a major determinant of how large a scanned file will be.  Unless you specifically need to use them, avoid scanning to TIFF or BMP files.  JPEG is a good format to use for images; it doesn't have all of the perks of a PNG file, but it does tend to compress the image to a smaller size.  PDF files are a mainstay of document scanning, and offer many useful features, but you can often get a smaller file by using an alternative format (such as DOCX).  Not all scanners will have the same range of file types to choose from.

Enable file compression

Most modern scanners have the ability to compress files so they take up less disk space.  Typically, this setting will be called File Compression, Scan Compression, Compression Ratio, or something similar.

Your scanner's user manual can tell you where to find the compression setting.  On a Ricoh MP series copier, for example, it would be in User Tools/Counter > Scanner Features > Send Settings.  Some scanners will allow you to tweak the amount of compression, while others will just have a basic on/off setting.  Compressing your file shouldn't change its appearance in any noticeable way.

Post-scanning adjustments

Once you've scanned your document or image to a file, there are still other things you can do to reduce the file size, depending on what type of file it is and which programs you are using.  Most image editors (including Microsoft Paint) will allow you to resize an image, and others (such as Microsoft Office Picture Manager) also offer the ability to further compress the file.  Adobe Acrobat includes a Reduce File Size feature that can shrink your PDFs.
