LExmark X264DN grinding noise while printing

[spree]

Can anyone help with grinding noise while printing? It is one gear, which is under the gearbox (gearbox was completly out) and the gear is situated to the cube. The cube is in the printer.
When I look to the parts list, this gear is not supported as a spare parts.

Anyway I can make mistake and the gear is the next problem, but when I look at the gear, the gear is little jumping.

Do you have any idea what to do?

Thank you.

See photo.20170314_125128.jpgThe gear you do not see (the cube yes), but the gear has the safety pin on it.

What does that gear drive? Quite often the gear you see twitching is right next to the damaged gear, or driving something that just won't turn. =^..^=

Do you have any idea, how can I check, which gear is fault? Because when the gearbox is mounted, it is terrible to see some hidden gears.

Gear drive = gear box?

Disassemble it and start turning gears by hand. Or read the manual. Or both, that's what I would do. =^..^=

The cube is a clutch. The clutch have shaft and at the end of the shaft is the gear. I think this clutch, or something behind clutch is bad. Nevertheless this spare parts are not awailable for this machine.
The gear box (gear drive) is good.

I think the part you need is

40X5370 - Media feed (ACM) clutch

I've replaced this on the X363 (same printer). Be prepared to do some splicing as running the new cable through the side of the chassis is impossible. The instructions that come with the clutch reference a splicing connector which isn't in the box.

Yes thats the part!!!

In manual it is!

P.S. the gear box has the long lever to the front door (when you open/close front door). I disassembly all front door parts and I turn with the doors left/right/up/down, but I can not disassembly the lever from the front door.

Yup. I don't know if I was just missing something or if removing that arm was just simply a pain in the ass. I was being extremely careful because if you break the end off, you'll have to replace the whole gear assembly.

When you brake it, you must change whole gear box or front door cover

Re: LExmark X264DN grinding noise while printing

Depending on which part broke.

40X5367 - Main drive gearbox (in motor) - If the tip of the arm broke
40X5379 - Front door cover - If the tab with the hole for the arm broke

That arm is attached to the drum engagement gear in the main drive assembly. I've broken the tip of the arm on the Dell 1720's (Lexmark E250) and had to replace the main drive assembly. The design is the same as the X264.

The lever is out

Thank you for your help.

Today I changed Media feed (ACM) clutch (40X5370), but the noise is still here. The clutch is jumping. I think the gearbox is fault, or the shaft.

Any idea what to do? What is fault?

Re: LExmark X264DN grinding noise while printing

The only other parts are the gear assembly or the autocomp assembly.


Can you tell/see if the issue is in the main gear assembly? The end of the autocomp (the arm with the rollers) has a small gear cluster in it. Perhaps there's something wrong in there making it appear there is something wrong in the main drive assembly?

What I see the gear assembly is good, but the autocomp (the arm with the rollers) I must check it, because the grinding noise is when the paper is picking up.

Here is the picture of the autocomp:
