mpc2050 -51 noise

[Mark Bbb]

If someone can tell us what exactly needs to be lubricated to elliminate all the regular noises on these models - without replacing parts - we are willing to pay you the amount you want.
You can send me a private message.
Thanks in advance.

Grease the sep pads in the paper trays (all the points that slide down into the groove. Replace the springs on lube bars in PCUs (they have "updated" springs now), or you can stretch the original springs a smidge. As for the fuser grumble, nothing to lubricate there, just have to replace that.

There was a bulletin on that 7 years ago.

Thank you for your reply.
Would the springs be the issue? Have you tried it yourself?

Re: mpc2050 -51 noise

The updated springs (AA063690 - shorter and not as flimsy) will get rid of the high-pitched squeal for a while. Have put them in many units, especially after the tech bulletin was released, but in a pinch, I've just "stretched" the original springs, so that hopefully it will give a little more down force on the lube bar. Takes about a minute per unit to change out those springs and they're cheap!

Re: mpc2050 -51 noise

the problem encountered in the field and the dust of paper that settles in those points. replace the pad and solve the vibrations

Re: mpc2050 -51 noise

I will clean the pcu's and remove the lubricant bar and test without them to see if it is better.
If it is (better), then you are wright and i owe you one.
Might take awhile because there is a lot to do here.

if you are talking about Vaseline... that is a VERY low temperature substance... IT WILL NOT LAST LONG in a fusing unit.

get some high temp bearing grease or buy the Ricoh hitemp fuser grease. They have specs for lubes for a REASON!

As for if I have tried it, yes. In verified amounts and only on the points shown in the bulletin. White lithium is good. Vaseline will not work. Read the bulletin!!!

Re: mpc2050 -51 noise

sp5804 - 47 is checking the movement of the Magenta drum.
I have removed the lubricant bar from this unit and checked with this sp, and... the noise is the same...
So, question remains...

Re: mpc2050 -51 noise

The noise is from not enough lube on drum and now you have removed it completely, put lube bar back in with new springs and try again.

OK, i thought the noise would be the friction between the lub bar and drum...
Now i understand!
Thanks!

Re: mpc2050 -51 noise

I have replaced all 8 pcu lubricant pressure springs (AA063690), and you know what?
It's still beeping.
So, my guess is that the lubri bar is almost empty, thus not giving pressure enough onto the drum, even with the modificated springs...
So, if you want to solve this issue well, you need to replace the lubricant bar.
Anyone has tried this?
Anyone knows where to order this lubricant bar?

Re: mpc2050 -51 noise

Are you sure the noise is coming from the drum units? Also check the exit section. I have had high pitched squeak from there on these machines.
