This means I believe that the thermistor, or possibly the fuser, has failed. Our 8500 is in exactly this state at present. It occasionally works for a few pages after it is turned on, then it stops when the two rear LEDs turn on.
We had a new thermistor fitted but this has not resolved the issue. Not currently clear whether the new thermistor was incorrectly fitted, the base had to be filed to fit and it may not be close enough to the hot roller, or whether we have a more fundimental problem.
Any other views on this?
Thanks

    Further to my solution:


    I have fitted a second ATH1401 Thermistor and the 8500 is now restored to active service. Happiness! : )


    See how to get the Fuser out in order to fit the part here:

    The correct part is shown here:

    The part I bought was from here:

    http://www.applemacparts.co.uk/store/ind...



    The problem could be that the design of the part I bought is slightly different to the original, you have a file a small plastic alignment lug off the base since it doesn't align with the alignment hole in the Fuser AND the Thermistor itself has two sharp lumps where it bears on the Fuser - unlike the original part shown above.

I have a HP LaserJet 1312nfi that is giving me a FALSE paper jam message. I repeat - FALSE PAPER JAM IN BACK DOOR. False false false. I have uninstalled it on my computer and nothing. I have opened it...


Hello Chris! Welcome to FixYa!

If you are facing False Paper Jam error in your HP Laser Jet 1312nfi but If you cant see any obvious paper jams, try to look closely into the rollers or the inside. There could be some tiny paper shreds stuck within those rollers. Or there could be a tiny piece of paper blocking the printer's sensor and thus giving you a false paper jam error.
The rollers should be cleaned if the paper fails to feed smoothly into the unit. All document and media rollers should be cleaned using a lint-free cloth lightly moistened with water.

1. Turn Off the printer and unplugged power before cleaning the rollers. This will allow the rollers to be turned by hand in most cases.
2. Remove the rear access door to access the rollers. Clean any dust and debris from the rollers.
3. Open the back of the printer and check metal paper rollers (not the rubber rollers) in the interior of the printer. They should be clean and move freely. If these are not bright and shinny or have buildup on them, they should be cleaned. Also clean any dust and debris off of the rubber rollers.
4. Close the back cover and reattach the rear access door.
5. Plug the power cord back in and power the unit up. It should reinitialize for about 20 seconds.
6. Print another extended self-test page.
After following these steps carefully, False Error message will be disappeared.
I hope this solution helps you
Let me know if you have any confusion in your mind.


Sir, Your Rating as FIVE Stars for this solution and words of appreciation will be esteemed

Orange light blinking, cleared paper jam, changed printer cartridge, won't print subsequent documents.


Double check all doors/ rollers for small pieces of paper stuck in the rollers. Sometimes just opening the door in question and closing will reset the paper jam sensors. Paper jams can be smaller than your pinky finger nail. So double check,

Comment if it still isn't working.

HP 6940 print head jammed.resume light flashing


Welcome to FixYa!

Usually print head/carriage jam is caused by paper jams or previously cleared out paper jams that left a small torn paper inside the printer.

Turn off the printer by pressing and releasing the power button.
After the printer turns off, press the power button to turn the printer on again.
The printer might go through a warm-up period of up to 2 minutes. Lights might flash and the print carriage might move. Wait until this warm-up period is complete. Then try to print a self-test page. If it is able to print, the issue is resolved. (See instructions at the end of this article on how to print a self-test page.)

If the printer does not turn off, clear any paper jam. Press the resume button on the printer front panel. If the paper jam does not clear, continue with this procedure.

Leave the printer turned on, disconnect the power cable from the printer, and then disconnect the USB cable from the back of the printer.

Push the two latch handles on the rear access door of the printer toward each other, and then remove the door. Please refer to the image below.

Remove any paper that is inside the printer by pulling the paper out from the back of the printer.
If the paper jam cannot be removed from the back of the printer, raise the printer cover, remove the paper jam from the front of the printer, and then lower the cover.
Remove the paper carefully. It is possible to damage the printer when removing paper from the front of the printer.

Reconnect only the power cable. If the printer does not automatically turn on, turn it on by pressing the power button.

Again, the printer might go through a warm-up period of up to 2 minutes. Lights might flash and the print carriage might move. Wait until this warm-up period is complete. Then try to print a self-test page. If it is able to print, the issue is resolve. (See instructions at the end of this article on how to print a self-test page.)

If the Power light is blinking and the print carriage is still in a stalled position, continue with this procedure.

With the printer turned on, open the printer cover. The print carriage might move into the access area automatically. Allow it to move to that position.
If the print carriage does not move automatically into the access area, turn off the printer by pressing the power button.

Disconnect the power cord from the back of the printer.

Looking in through either the ink cartridge access door or the output paper tray, make sure that no obstructions under or around the print carriage are blocking it from moving.

Make sure that the print carriage can move freely across the width of the printer by gently pushing the print carriage to the left and then to the right. Clear any obstructions.

Remove and reinstall the print cartridges. Make sure that it is properly installed back.
Close the printer cover and connect back the power cord.
Print a self-test page. If it is able to print, the issue is resolve. (See instructions at the end of this article on how to print a self-test page.)

To print a self-test page, make sure the printer is turned on. The USB cable of the printer to the computer must be disconnected to make sure that we are isolating the printer problem.

Press and hold the Print and Cancel button at the same time. Make sure that the printer is loaded with paper. The self-test page will like the image below.

ROYAL RL170MX Shredder won't shred


Did you ever put shredder oil onto the cutting blades?????
The blades can clog with paper dust and then it can't shred as many papges as it should or even jam completely...you should occasionally shred a sheet of paper with shredder oil poured onto the sheet.

1) take a flash light and inspect the paper path just to make sure there really is nothing there.

2) print a test page from the printer by pressing the big button ( I think) one of the buttons, can't remember I work on so many models

3) take out cart. turn off then on, install cart. and do step 2
