Our Polygun TC was left on for several days. It is difficult to thumb push in the 2" glue slug and is spewing a dark molasses color from the glue tip. How do we clean and clear this problem to...


Hi,
The dark molasses is the old glue that is in the gun that was "cooked" I don't think the tool is burnt out. I would take a shot at pushing sticks into the gun while it is heated up until the glue that comes out of the tip turns clear. Then the gun should now be "cleaned"
Then unplug it, so that it cools down. After it is cooled , you will be able to remove the old dried up goo from around the tip so that it is completely clean.
WARNING: DO NOT IMMERSE THE GUN IN WATER
The gun is not really designed to be disassembled and cleaned.
The next time you use it, it should be fine.
Hope this helps,
Mark

With the switch in the up position(toward input screws on back) and placing the ohm meter probes; one on the upper left, one on the lower right, continuity is read. Reversing (one lead on upper right, one...


I answer questions for free.
I understand electrical devices.
It is unclear how many screws are on the switch you are testing.

If your switch does not show ohms when the switch is in one position, then it sounds like the switch is bad. But you can read information below for more information about your testing.
You can also add a comment and continue the discussion.

Let me provide more information about switches because you seem interested in electricity and the information may help us understand where the other is coming from in case you add a comment needing more help:
2 screws on switch: (excluding ground screw)
An ordinary single-pole switch usually has 2 brass colored screws.
These screws only read ohms or continuity when switch is in one position.
When the switch is in the other position, there are no ohms that pass through the switch.

3 screws on switch: (excluding ground)
A 3-way switch has 3 screws. There are 2 brass-colored screws and one dark-colored screw.
Put ohm tester on dark screw and continuity will show between the dark screw and one of the brass screws.
Flip the switch and ohms will test between dark colored screw and the other brass screw.

4 screws on switch. (excluding ground)
There are 2 screws on each side of switch.
This type of switch might be a special purpose double-pole switch.
Or it might be the more common 4-way switch.
Add a comment if you have a switch with 4 screws.

Below is a typical 3-way switch application showing the dark-colored screws:

Here is a typical 4-way switch circuit:
Notice the switch in middle has 4 screws:

I want to change the signature on my outgoing emails. How do I do that? Can I add a logo to it?


1. Go to your email box.

2. Click on 'Options' (upper right, blue letters).

3. Scroll down to and click on 'Signature' (second column, under 'Management').

4. Select> 'Editor: Plain | Color and Graphics.

5. Enter signature text and/or graphics (you can 'Copy' and 'Paste' text and/or graphics directly into the input field).

8. Check the box:
'[/] Add signature to all outgoing messages'
Or leave the '[_] Add signature....' box unchecked and check box below compose area (when sending messages) '[/] Use my signature'

9. Click on the 'Save' button (upper left, under 'Mail' tab).

---------

You can 'Copy' and 'Paste' your pictures directly into the input field (if the image is JPEG format - ".gif" or ".jpg"), but there is limited space. If your picture suddenly disappears, it may have gotten corrupted during the process, try it again. Note: some images may not allow you to copy them due to HTML restrictions on the page.

If your picture is in your computer, you can send it to yourself via an attachment and it will be in your 'Search Shrtcuts' > 'My Attachments' - 'My Photos' folders.

After you locate your picture in the search shortcuts folder:
1. Double-Left click on the photo to open.

2. One-Right click on open photo to reveal the pop-up menu.

3. Choose 'Copy'.

4. Go to signature input box and one-Left click on target area to set cursor.

5. One-Right click to reveal pop-up menu.

6. Choose 'Paste'.

Or you can upload your image to 'Photobucket.com' and 'Copy' it from there.
Photobucket
http://photobucket.com/

------------

The Color and Graphics version of Yahoo! Mail also gives you the ability to include HTML graphics in your signature, by doing the following:

1. Locate an image (".gif" or ".jpg") that you wish to add to your message. This image can be selected from the Web.
2. Once you find your your picture of choice, right-click your mouse and select "Copy" from the menu that appears next to your cursor. Note: some images may not allow you to copy them due to HTML restrictions on the page.
3. Login to your Yahoo! Mail account.
4. Click the "Mail Options" link in the upper right-hand area of the page.
5. Click the "signature" link in the left-hand Personaliztion column.
6. Make sure the cursor is in the Color and Graphics signature field and paste your copied image by pressing "Ctrl+V". Your fonts, sizes and colors should all remain the same. You can also resize your image.

If you would like to edit your signature in the future, just return to the Signature area, make the changes you want, and click "Save."

Fault code J50 & dark strip.


This is for a Mita 1560 Photocopier (analog)
J50 was caused by exit sensor not sitting correctly in its bracket,I fixed this by pushing it until it
clicked back in.
The dark lines & double imaging can be caused light getting onto the drum ,or if the drum gets
cold (so I have been advised) which one it was for sure I will never know because when I
returned the next day & fixed the exit sensor the copy was OK.

Colors bleeding, red tint around images


The liquid coolant between the guns and the lenses may be fogged, low, or both. If the red gun has fogged coolant, you'll see red fringing around objects. It can be drained and refilled with new coolant, but it's gotta be the right stuff. You may be able to get some from a junk set, as I have done with success. Shine a light into the front of each lens. If the liquid has gone bad, you'll be able to see it.

Double images


You could have some type of convergance (three colors, three guns) problem. Also a misaligned horizontal or vertical oscillator.Ceck to see if any of tiny magnets around the bell of picture tube or next to coils in and around bell of pix tube are missing.

You need to use the convergence feature for your set. What this is is having the three color guns aligned properly, There is hopefully an automatic adjustment on your set-up menu, if not adjustments for each seperate gun. Basically you adjust the lines of the adjustment screen so the line turns black and white. You can easily see what needs it.

If this needs to be done manually, it is a chore. Contact me for directions how to do this. It is best left to a pro but this can get costly and wouldn't hurt if you tried yourself as if someone comes in, the cost would be the same whether it is out slightly or severely.
