MPC2050 waste toner container, empty or replace?

Re: MPC2050 waste toner container, empty or replace?

Hi guys,

I am having a trouble with a MPC2551 and waste toner bag.
We usually empty both of them and as for now we get no problem.

But Yesterday we had and issue. After emtpying TBs, machine won't clear message and stop working.
We managed sp code to reset (Sp 3 902 17/19/20) but machine goes into near "empty condition" and stop after few copies.

We notices that SP 3-800-001 after reboot goes into condition "2" while SP 3-810-001 stays in condition "1"
We checked sensors and they look good. Changed toner bags with recycled one with no success.

What else can we check?
we raised sp-3-800-003 to 2.000 in order to have more time to investigate, but no light at the end of the tunnel.
Any help is appreciated.

Thanks

My tech solved it.

Deeply scanning SP pages we found SP 5 607 13 (not mentioned in our italian manual)
Switched to 1 and then back to 0 (after reboot) solved the issue.

Hope to help someone!

Regards.

We always reset the counter just so other techs can see what it's at. Has anyone else had issues with the new WTBs (front ones) being defective? Gear shaft is bent, causing excessive noise and sometimes service code. Happens on about 50% of the bottles we've bought recently.

A while back, I believe, there was an RTB about this. they say that the coil jumps out of the guide that holds it in place and then the noise is the result.

What is 5607-13? My USA service manual (current version, just downloaded) doesn't list it.

Same thing here - my manual also does not list it.

There's a good chance he scrambled those sp-numbers. I don't have a mpc2050 with me to verify atm, but I do remember SP5067 is a valid sp-mode? Changes part replacement type between tech<>user.

I was wondering about that same thing when I went hunting in my manual....

Re: MPC2050 waste toner container, empty or replace?

Very sorry. Mistyped it. the right one is SP-5-067-13 (MPC 2551)

But At least the problem was not solved.
Machine still wants a new waste toner....
even with a new one!!
WTF!

I'll look through it.

Regards.

@polarbear can you post RTB about the coil.. i don't have tessa access! Thanks!

He was referring to the MP C2051/2551 manual, not the MP C2050/2551.

Have you reset the cleaning unit PM counter, SP 7804-018?

It would be nice if you would tell us exactly which waste toner container you were talking about (we can't see your machine after all). But if you are referring to waste toner container 1, look at the cavity in the machine the container is installed in. On the left hand side, you will see the gear that drives the augers inside the container. Pretty close to the gear, you will see a photo-interrupter style sensor. That is the sensor that stops the machine when waste toner container 1 is full. As such, if that sensor is contaminated with toner, not even a new waste toner container will help. Try cleaning that sensor and see what happens when you put the new container in.

Thank you guys for your help. Machine is a MPC2551
Waste toner container 1.
Photosensor was cleaned.
Sp 7-807-18 or 23 do not cancel the error.

May be a faulty board?

Use the input checks in the service mode to check the operation of the waste toner collection full photo sensor.

Also, check the operation of the auger inside the waste toner collection bottle. I have had one delivered, brand new with the auger snapped.

Also, make doubly sure that the message is not saying waste toner collector 2. This is a separate waste toner collector that collects waste toner from the transfer belt unit only. It can be emptied, but usually if this is full, the unit has already gone past its life.

Re: MPC2050 waste toner container, empty or replace?

Bit late to the party here, but I have a bunch of these.

My basic recommendation is dump the door bottle every visit. That sucker is the peanut bladder of toner collection bottles and doesn't hold much.

The side tank will hold much more and will go 120K easy. I typically empty the door 2-1 over the side tank.

I do not reset the PM counter for the side tank unless I actually replace the cleaning unit. I want to know how many copies are on the cleaning unit if the customer has an issue. The usual replacement by the book is 120k. I have had customers that do a lot of full color and the cleaning unit won't make 120k before you start getting smeared images after the first 5 or 10 prints/copies. If a customer does very little color and sticks to mostly black, that cleaning unit can go 200k or 300k with no real issues.

Re: MPC2050 waste toner container, empty or replace?

Waste toner bottle 2 detects full when it starts to back up and the collection coil shifts and trips switch. sometimes you just have to push the coil back over.
