RE: How Do I Silence A Squealing Pressure Roller And/Or Toner Cart. Roller?

Hi. I have a question that I need your help with a laserjet printer.

I have determined the problem with some simple testing, a squeaky rubbing roller with my old legacy Lexmark X215 Laserjet B&W unit. This is a discountined unit. I believe the rubbed squawking is coming from the pressure roller that butts up against the toner cartridge roller. When I have the door open to the toner cartridge compartment and I use a pen cap to push down the lever to run the unit (as if I had the door closed) while printing with the toner cartridge full seated in its position in the unit I hear the squeaking noises when I print. While having the lever down on the unit (with the door open) and the unit is running, if I just pull the toner cartridge out slightly from its locked position, the squeaking stops. The only contacts between the toner cartridge and the unit is the gears on both sides of the toner cartridge in contact with the units 2 gears, the toner cartridge roller against the pressure roller of the unit, and the electrical contacts on the side of the toner cartridge. Noise is not coming from any of the print rollers in the unit.

Now here is the thing I will add. I may of done something wrong here unaware of what I did at the time– if I did indeed anything wrong or not. I had wiped the entire length and circumference of the toner cartridge roller with a clean cloth just prior to inserting it back in the unit. It was printing many black speaks and blotches on white ditto paper and by cleaning the toner cartridge roller, it went away. Since then it squeaks. I had oiled the 2 gear wheels with a few drops of a 3-In-One oil on both the unit pressure roller gears and the toner cartridge gears. Since then I was told not to use oils and I have cleaned the unit up. The oil drops I added were not that bad as I thought at all. A few drops got on the printer rollers by accident earlier. Using denatured alcohol, I cleaned up the printer rollers and now they are clean. Actually, I have cleaned them very nice. There is no noise or squeaks coming from the print rollers.

I have attached to this post a PDF file from Lexmark regarding their X215 unit. Please note that the pressure roller is number 4 in the diagram.
I have also attached the PDf file for the whole main unit. The frame assembly fits inside the main assembly for your information.

What would cause it to have a rubbing squeak noise? This testing tells me that it is the gears or the rollers – pressure roller in the unit or the toner cartridge roller? Will this go away on its own in time? How can I correct this?

I have tested the print quality and everything is okay. Now, when it prints it makes a nasty rubbing squeak sound.


Any help is much appreciated.

Please reply.

Thank you!

 

Any way you can shim the toner cartridge?

 

@ Caliban & all:

Thanks for our reply...

A good idea! Yes, I should have added that part to my post too. I did try to wiggle and shimmy the toner cartridge in the printer and you cannot wiggle or shimmy it. It is SO tight and locked in there unless you begin to pull it out by the last stage of pulling it out before fill removal. What I am calling the "last stage", kind of like the last "click" before it fully seats in the final resting place in the printer. When it is fully seated in the printer is when the squeaks happen. I got a funny feeling the toner cartridge roller and the pressure roller (part of the printer) and rubbing and making that squeaking sound. I may be wrong and it is something else.

Question is why would they be rubbing now and making a squeaking noise now? They didn't before? They do (I think.) have contact with each other when the toner cartridge is fully seated in the printer.

Any further ideas on what you think is happening? ...any solutions?

Please reply.

Thank you!
