Motors MX-4070

Re: Motors MX-4070

I pulled the paper feed motor (just above the transport motor), same part number, and there is wear on the gear in the same area where it meshes with the next gear. So looks like that one will be next. If that happens, that will make 3 major drive assemblies in one machine. 38K blk and 22K clr.

We have several machines that have multiple motors fail in this way and several times per machine. We have tried the whole assembly to see if that is the issue, it wasn't. UGH

Re: Motors MX-4070

FYI: for a temporary fix that actually worked until part comes in

I shimmed the motor assembly mounting screws by applying washers in between the copier frame and motor mounting bracket. This moves the "bad" part of the gear away from the mesh and good part of the gear to drive the assembly.

hope it helps for you too

Re: Motors MX-4070

The motor issue is 90% of the time to do with toner between the gears due to spillage during shipping. The toner on these models has dev in it as well and as such is quite abrasive. When replacing motors strip ad clean the whole drive unit or the issue will return. lubricate with the correct greases as per the service manuals. I noticed in the photos the gears are very dirty. I will bet this is toner / dev.

Very true. However, we have had several units where we replaced the whole drive unit and still had the issues occur. As I mentioned earlier, we are looking into different grease options here. It was just never really been an issue before.

Re: Motors MX-4070

Whats been happening is the DV units are filling up because of a design deficiency. There is a bulletin about it. So now the units will hold more without clogging the tube. CCE2027r is the TT.

Re: Motors MX-4070

I have had to replace several motors, RMOTP1045FCP1 , that cause error code L4-03 and L4-02. No sign of gear wear, just failing motor. Hardly ever had to replace a motor on any of the old Sharps.

Re: Motors MX-4070

I have had to replace loads of these motors, mainly for fuser drive errors, no visible wear on the motor gear but swap with the paper feed motor for testing and always then throws up transport error proving motor failure. Again, can be on devices with any amount of mileage, from really low eg 20k to bigger volume.

Must be a lubrication issue because no other obvious reasons!?

That's settled. Factory defects in the manufacture of the motor.
