Knocking noise I am hearing a knocking noise on the left side of the printer (Looking at it from the front) about the middle of the machine towards the front. Any guess on what is causing it and how to fix it?

    Heard the noise with toner out. Already tried swapping the fuser out and noise still came back. Noise also followed toner to another known to be good machine. I am wondering if it is internal gears that are having issues that are not worth fixing.

Remove the toner cartridge to hear if the noise goes away.

Pull the 2 caps with the arrows on them in the rear to check if the 2 Phillips screws are tight.

If you loosen those screws, you can pull the FUSER out and check the gears.

    Trust me on this. The 4000 is the best HP ever. I would get it fixed if it were mine.



    I still think some assembly is just loose.

How do I sort the knocking sound on this machine hp laserjet M5033 MFP


Knocking usually means the gears are not turning the cartridge rollers properly. This would be why it probably doesn't knock with the door open when you run a motor test.
Take the Cartridge out, close the door, and and let the motors turn and see if it knocks still. While you close the door look to see if there is a gear that protrudes from one side as the door closes. If the gear does not come out when the door is closed then it will not turn the cartridge rollers and would cause the knock. Also, if the gear does come out but does not link up to the cartridge fully it can cause the same kind of sound. You would also get a similar result if the gear's teeth are stripped out on the drive side of the gear.
Many models do not have that type of drive gear. They may have a drive gear on the left side of the cartridge compartment. Look at that to see if it show wear and tear.

The only answer I'm afraid is to visually inspect to see what's knocking. Look for misfeeds and paper jams, they are the most likely problems

Throw that piece of garbage out and get an HP or Samsung. One of these has plagued my office for years and I've spent countless hours plotting its demise. Worse than useless: unreliable.

My printer is Lexmark x5650. It prints well, but when i try to scan it starts making knocking noise after few seconds and continues 15 sec. then i get a message on printer's control panel display...


Unrecoverable scan error indicates a hardware problem. It's also evident with the "knocking noise" in the printer. I strongly suggest you contact Lexmark technical support for assistance.

Scanner bed is knocking, is there a special adjustment on it to stop the noise?


Hi,
every scanner I have owned makes a knocking noise. That includes Epson and Canon and HP.
There is no adjustment that I have found.
If you are concerned ring the Dell Support phone number.
Cheers,

Lexmark t644 making knocking noise when printing. I sprayed some air duster around the rollers but the knocking still persists.


Could be caused by the fuserroller. If the machine has been out of use for some time or if you do not print very mutch, the pressure roller of the fuser gets flat spots witch can give a knocking sound.

Dell 5310n knocking noise when printing envelopes


This is a good thing. The 'knocking' noise is actually called a "Thumper". It's purpose is to get the air out of the envelope before it hits the fuser. Air in the envelope typically leads to creases on the envelope itself.

Minolta QMS 2350 showing service call 15 xfer belt


Your error means -
Incorrect pressure by or separation from the transfer belt cleaner
Remedy
1 - Check the Belt cleaner positioning sensor pc9 (located at the rear on the left hand side towards the top when looking from the front of the printer)
2 - Replace the Second image transfer roller pressure/separation
mechanisms.
3 - Check the Image transfer roller pressure contact solenoid SL2 (this sits more in the middle behind the printhead)
4 - Replace PWB-A.
5 - Replace PWB-P.

Hi Elenor.

With the blech line of dust is easy - if you have a thin screwdriver " _ " one and a torx10. Remove the bezel from the front panel and push with the thin screwdriver in the small holein the panel. While pushing (not hard) easy slide dhe front panel towards the back of the printer. Unplug the ribbon cable carefully. The panel unmasks 1 screw. There are 3 in total. The other 2 are under the scaner cover - pull it with force straight up untill you remove it.

Unscrew the 3 torx10 screws then pull the cover with the glass easy from the back - up lift ti untill the front releases.

Be carefull with all the ribbon cables.

With the other problem...

Where (in witch part of the printer) do you heare the noise?
May be true - becose of the belt but not necessary because of it. You can have a piece of paper or an obstacle in the left or right sice of the printer in the craddle's path, or the spring that pulls the best straight could be weak.

Have fun
