mxm3070 and all series with mx561gt toner

[oscarconil]

I have problems with most of the mx561gt toners.
The machine is working perfectly, it asks for the toner, the new toner is placed and it begins to add toner and when the copies are very stained due to excess toner
In simulation 25-2 the setting goes to 55-60 and the only solution I can find is to deactivate dv in simulation 7-1 and make black copies to use up the excess toner,
then do 25-2 and adjust the developer again

Greetings and thank you

That might work temporarily, but you would be best served by changing the dev., run 25-2 and look to get a normal reading of 115-130. Developer has a definite life span, after which it can no longer maintain a correct carrier to toner ratio - the carrier being the polymerized ferrite compound (iron filings) that degrads just like rocks in a tumbler lose there jagged edges. If that developer unit can't produce an acceptable reading - change it out with one that can.

Hi
How much did the devices run? Is it original toner or cheap, imitation garbage? I have dozens of these devices out at customer sites and not a single one with this error.

The advice to only use OEM toner is good advice. We have several hundred of these machines using MX-561 toner, and ONLY provide genuine Sharp to contract customers. The others may be tempted to buy generic, but chances are that problems will arise - quality issues, F2-78 errors as dev unit spews toner on image density sensor, poor yield on drums & fusers as toner particles are too abrasive. A Sharp engineer told me there are approx. 200 variables in the formula for toner - particle size & density, melting & fusing temps, tribo-electric charge characteristics, etc. It is very high tech these days, especially with the newer polymerized coatings. There are ways to get OEM cheaply for both dealers & end-users. Why risk it with generic?

We used to have issues on the MX5141 series with aftermarket toners that would keep telling the machine to force-add toner, and eventually the DV unit would be full of toner and throw an error. Replacing the DV did nothing, and only replacing the toner would make it stop.

[oscarconil]

Yes, I have always used original toner and it has happened to me on almost all machines with mx561gt toner.

It has also happened to me with the new developer with very few copies and it is just when changing the used toner.

Sharp technical service doesn't give me a solution and I don't know what to do anymore.

I just wanted to know if it has happened to more machines.

all the best

As with anything else, make sure your firmware is at the most recent level. I would also suggest replacing the developer unit and material, replace or rebuild the drum unit, and perform the calibrations. Maybe even replace the toner at that time as well. Make notes of when you replace everything, then see how long it lasts

OEM or generic, seems to not matter, extremely common. DV life is supposed to be 560K, but this can happen at under 100K. Firmware doesn't seem to help.
Default reference for AT DEVE ADJ_L_K=128
Default reference for AT DEVE VO_L_K=128
A good DV spin usually results in something like 130/143
I've taken another developer unit (that was so out of whack it resulted in F2-40 codes and jammed at fuser), installed and calibrated to that one, cleaned toner sensor on the old DV unit after running 20 black pages in aging mode, reinstalled and problem disappeared.
There is a bulletin for shims under the ID sensor to adjust the angle - ARE-1455 (2 'lower sheet' mylars PSHEP7235FCZZ), results may vary. Maybe it's a toner lot # issue.

Please guys help me out
how can i clear total counter in mx 3069

MX-3069 is not an actual model and you'll need to contact Sharp for the procedure and provide a reason for resetting.

sound like bad developer.

Hello, can you send me that modification bulletin? Sharp Spain doesn't know anything and they don't know how to solve it.

I am seeing the same thing. When customer changes the toner the machine overtones itself. So far the only thing I have found that seems to work is powering off the machine. Changing the toner and then powering the machi8ne back on. I now know I am not the only one fighting this issue.

Sounds like a classic case of someone not "shaking" the toner.

We actually send all our toner boxes with big labels saying "SHAKE TONER WITH VIGOR x10 TIMES BEFORE INSERTING INTO MFP", just to avoid this.

Also, be sure to calibrate and clean the machine when doing a PM. These BW machines are great. I have one client with almost 3M printouts. Never had issues.
