Re: mpc 3500 false add toner messare

hi

to have a good value for the amount of toner in the cartridge make an ENGINE clear RAM and then change your developpers.

the whole assemblies or just the powder?

Re: mpc 3500 false add toner messare

If your'e going to do that, just change the developer, not the development unit.

Re: mpc 3500 false add toner messare

how about just doing a developer change and not doing a ram clear?

Re: mpc 3500 false add toner messare

If the printout quality is fine there is no need to start with replacing the developers or developers units. Faulty toner pumps are indeed a possible issue but on the other hand it's unlikely that two of them failed at the same time - still it's not impossible. I know that messing around with the SP called "new unit detection" can lead to strange issues - so make shure to keep it on the default setting.

Doing skyshots is a good way to check the toner supply mechanism. Usually a toner pump is never broken but it doesn't transport the same amount of toner into the dev unit like a healthy pump can do. So if the density fades away during performing skyshots, there's most likely a problem with the pump or the tube (chunked toner). There's also the toner hopper assembly that turns the bottles - I haven't had any issues with that but I read about faulty clutches so the bottles didn't turn or turned just sporadically.

Doing an engine reset - well it's indeed a harsh thing to do but not a problem if you upload the data to your sd card before.

Last but not least: Does the machine run with original toner?

Re: mpc 3500 false add toner messare

printing out the smc data is a better idea than copying NVRAM data to an SD card. Better to know the data you're resetting than to put all tha data back in, as some of it caused the problem. Hence you're putting the problem back into the machine

Re: mpc 3500 false add toner messare

You should also have at least the non default SMC page but having a backup of the NV-Ram data on your SD card is useful in case you find out the reset doesn't do the job, so there's nothing wrong with the data. Besides I got a related toner/detection issues fixed on other MPCs (last time it was a MPC6000 iirc) doing a reset, perform a copy and restoring the data afterwards. I know it's not really logical but todays MPCs also have ID/chips with some sort of memory located at the TD sensor elements and toner bottles. So there's the engine software, the ID chip on the toner bottle and some ID chip at the dev unit involved in the entire toner control/detection process software-wise. If an engine reset helps getting some (maybe faulty) data resetted or changed/reflaggt within other components, it might be the an explanation why it still works after restoring the initial engine NV ram backup.

Of course there's no warranty that this procedure will help. Even if you get the machine up and running, the error might come back if the origin of the issue is hardware-related.

Like I said it's important to keep the SP mode for the new unit detection @default setting. One might change it to use entire SPC PCU's (supressing error message) without the need of swapping the TD sensor/ID chip but I've seen this leading to issues stated by the thread starter.

Re: mpc 3500 false add toner messare

you have a point. If the reset doesnt solve it, at least you can start over.

Re: mpc 3500 false add toner messare

The machine recognizes that the bottles are low of toner, I saw it in the services mode and it showed that cyan an black had neg. levels of toner in them I explained that in the beginning post. The customer showed me samples of the copies that they recently made and they had lots of cyan and black on the manuals, Customer made 40 sets all were were perfect, no fade. I cant see how a pump could be a problem the toner seems to be getting their. I guess when the bottles were installed, the machine thinks they are the original bottles. Is there a serial number on the bottle that coincides with a serial number in the machine somewhere? I did not think to check that until now! Thanks for the posts

Re: mpc 3500 false add toner messare

There is a lot no. for every toner printed on the bottle and stored in the RFID chip. The machine does calculate the toner consumption based of the attaction time of the tuner pump clutch (iirc) - so if the performance of the toner pump is somewhat limitated (but still working) you might get bad readings for the remaining toner percentage. If a ad toner pumps needs twice the time to transport the same amount of toner, you might see the remaining toner percentage value lowering twice as fast (example).

You are telling that the machine displays "replace toner" but still prints? In this case this isn't really a true toner-end condition (the machine will display a huge pop-up and refuse doing printouts in this case). I guess the message you are talking about is a little text located at the bottom left of the display?

Yes, I understand. but if I added a new toner tube the message should go away? The customer said they added a new toner tube and the message remained.
Yes, the message is in the lower left corner, saying replace black and cyan toner

Re: mpc 3500 false add toner messare

I can't see if you've said this already in any part of the thread, apologies if you have. Are you running OEM toner?

Re: mpc 3500 false add toner messare

Yes, that was the first thing I checked! I also ordered some toner to see if possibly they got a bad batch of toner, but I'm not holding my breath!

Tube? I think you're talking about the bottles. I haven't seen much customers messing around with the toner tubes^^

I'd suggest to let the customer ignore the status message until the machine stops working (=real toner end condition/big message on the screen). Then you or the customers need to check if the bottles for the empty colors are really empty in this state and replace them with new bottles. Maybe the issue will solve itself then and the machine will display a proper remaining toner status. Swapping toner before the actual toner end condition might lead to further miscalculations software-wise, especially if the machine's calculation wasn't correct before.

Re: mpc 3500 false add toner messare

Thanks Gift,
I had suggested that to my Boss the other day. I really don't want to replace or do unnecessary adjustments if I don't have to! I'll just give the customer some extra toner and tell them to add the BOTTLES when the add toner message does come up. Thanks again to everyone for all your suggestions, I will reply when or if any changes happen.

Re: mpc 3500 false add toner messare

Is the Toner remain bar graph icon showing on the display ?
Set SP-5061

How much of the toner remain in the bottles is showing on each bar of the graph on the display ?
