Have considered the clutch, but I have watched the the front locator disk and even turned it using a screwdriver to make sure it is fully in position, also can run the image causing probs in a several hundred run fine, but as soon as adding the black only pages to the set it goes off during a run, which I think must have something do do with the devs spinning with no toner through, maybe building up a charge? It may also be the reason if the machine is left alone for a long time it comes good?

if it has the latest version it will say 700/700i on ui when you turn it on otherwise you dont

If there was no toner In the Dev tank it would bring up a fault, I would be inclined to reload the IOT software if you haven't done so, what fiery has this got? External or bussle?

Is it any job sent does this or just one type of file?
I have had image quality problems with the c75 and reloading the software fixed this.
When you changed the Dev tanks did you use 700 tanks or 5000?

Nzer, I would be interested to know how you solved the cq issue.

Have just today managed to have this job run on a J75 with exactly the same results, in that the colour imaged mottled out over the run to an unacceptable quality, funny thing was that the operator of the J75 mentioned that they knew that their machine did this on plain stocks on similar types of print runs and usually had good results with running large b/w with minimal colour runs using plain 80gsm on coated 1 setting.

I did test switching paper type settings originally but only once the image quality had already deteriorated and made little difference

Returned to 700 customer this arvo and ran 70 books before had to stop for the day, all books looked good but not large enough run to confirm, will hopefully run more tomorrow.

Running on coated 1 slows the job considerably which is not a problem for the client, hopefully this is a suitable workaround, will post outcome.

Thanks

Returned to check machine, customer was up to 375 sets - (running 80gsm plain as coated 1) prints looked good - the odd one looked a little mottled but for plain stock certainly acceptable, customer is happy with the quality.

Thanks

Slowing the 700 down was the answer?
