HP4015

[krm]

Machine started with some slight grinding noise. Took out newer fuser for inspection and looked OK. Seemed a little difficult to hand turn. Reset it and loud grinding noise and rattling, etc. The swing plate gear seamed a little worn, but not obviously bad. Any thoughts would be appreciated and I've ordered the referenced parts.
Thanks.

Re: HP4015

the swing arm gears are showing were and tear replace them.
double check the fuser gears.
If there is wear in these ares it will sound more like a washing machine than a printer.

Re: HP4015

It has been my opinion and will continue to be so, that the issues with the swing plate/fuser drive are caused by poorly engineered press roller bushings. Especially the 42xx/43xx series HP's and it looks like they really didn't learn anything when they designed the P401x series.

The biggest problem has been that people will change the swing plate or even the fuser drive gear, but do not change the press roller bushings. Or worse the remanufacturer that provides your fusers are not changing them on every fuser they rebuild whether or not they appear to need replacing (we do).

The bushings get worn causing a wobbling of the press roller, this wobbles the fuser drive gear, and causes, in a short period of time, damage to the swing plate/fuser drive gears. HP keeps beefing up the swing plate gears and some companies make this gear out of metal in an effort to prevent this from happening. Yet the problem remains, because the root of the problem is never addressed. The bushings are the same as they have always been.

Do yourself a favor and replace the swing plate and the fuser (one from a manufacturer that replaces the bushings, preferably with OEM bushings) and you'll probably solve the problem, for a while anyway.

Interesting! Makes sense. I will ask my supplier about that.

Any trouble losing settings on this model from formatter removal? I have not replaced this model yet. Is it the same process? I know the assemblies are different.
Thanks in advance.

Sorry for very slow response. Replaced the fuser again and replaced all the swing plate gears via a kit. I took my time, cleaned and lubed shafts/gears and has been great for many weeks! I did it at the shop over a weekend and took me about 1 hr on a relaxed pace.
