HP LaserJet 5L - Creaking noise

[viktor weisshaeupl]

After many years of noiseless operation my HP Laserjet 5L has started to creak
when it apparently operates the transport mechanism. It probably comes from the
left front area, but I cannot locate it more precisely. The creaking is loudest
at beginning of operation, when printing several pages, it disappears. I have
sprayed PTFE-spray blindly to the left front mechanic parts inside, it did not
help much. I did not yet open the printer. Any similar experience and known
remedy?

Most often this is a toner cartridge problem. Have you got an old one that you
can try?

Good idea. I think the sound has started after changing a toner cartridge. And
maybe I still have the old one at home and not yet returned to the dealer. After
the weekend I will see. Is there anything I can lubricate on the toner cartridge
mechanism? I have had a look at that, too, but was not sure where on the toner
any shaft or axle engages and whether it is advisable to spray PTFE-lubricant
anywhere there.

I suggest you return the cartridge to your supplier for a replacement. The
likely cause is a poorly lubricated drum in the cartridge and that requires a
special dry powder lubricant.

I sprayed the left and right axle endings of the apparently rotating part of the
cartridge with PTFE-dry-lubricant spray from the outside, the creaking stopped.

Thanks for the tip with the cartridge. If it starts creaking again, I will bring
it back to the dealer.
