Question about HP LaserJet 2840 All-In-One Printer

1 Answer

Loud Screeching noise when printing.

Sounds like it is in top right side, but I don't think its the scannner motor. Sounds like a polygon motor going bad or maybe a spun bearing in a fan.

How do you test a polygon motor on a kyocera 1135

If the polygon motor is bad, it make a bad noise ( like a jet plane :) ), or you'll get an error code if the light beam won't reach the beam sensor. You can test if the motor spins by sending a print job with the cover opened from laser unit if the position of LSU is accessible. This motor spins only when a job is in progress not at the printer initialization. In some cases a noisy motor will not affect the quality of print. Don't try to pull out the polygon and apply grease on it because it won't work anymore. Those motors are equilibrated in laboratory and if you interfere its equilibrium state, won't work anymore.

L6 = Polygon Motor Lock Detection

Polygon motors are not serviceable items.

Try switching the machine off/on. If the code doesn't clear then you will need to get the motor replaced. Quite often the motor will have made a screeching or rattling noise before it fails.

Hope this helps
