printer making buzzing/humming noise

[dapace2]

hp color laserjet pro MFP M281fdw makes a humming noise when printing.  The whole office hears this so we're not talking about a low humming. 

hp customer support helped me solve the problem - replace any low cartridges.  We had two that were 20% remaining and the support person said hp printers are known to make humming noises when cartridge levels are less than 25%.  This tells me hp cartridges are only 75% usable.  I wish I would have known that before I bought the hp product.

Hi Dapace2,

Laser printers in general may do noises when one of their toner cartridges is running low. This means it may happen to any laser printer, not only a HP one. I am sorry you had to experience such an unlucky situation.

Have a nice day.

Our MFP M4777fdw has also been making awful noises lately during printing.  Our black cartridge is newer and has plenty of ink, but our color cartridges are virtually empty.  We really have no need for color at the present.  My question  is, can these color cartridges be causing the noise even if we're not printing in color?

Thanks.

Yes that could be the case as well. Also, another part that may be responsible for noise is the ITB (Intermediatte Transfer Belt). Sometimes, especially after a lot of use, the toner waste compartment of the ITB gets some rubbish or just to much of excess toner. Cleaning it may help with the noise and with the print quality as well.
