Have you reset the web counter? It will stop advancing when the counter hits 350k.

is it a band at the front end of teflon roller?
could be dev material , from pin hole in drum ,or charge grid too close to drum {remove grid cleaning pad}
happy copying peter

thank you for your time to reply on my problem regarding the web rollers.i appreciate it very much.i followed the instructions and the machine is working now

Make sure the correct web was used. The B600-750 are different from the 7155-7272. To be exact, the brown gear on the web of the B600 has less teeth than the 7155.

I had several machine with the webs not advancing or rolling out of the fuser after the pm.

Thanks a lot to Scott Lewis and Superfly.
I have the same problem and a very angry customer...
I really did not think to the items counter reset...

In fact, this 750 has about 500000 copies/prints made.

Next week i will go to the customer and thanks to your informations i hope to fix it !
Furthermore that machine sometimes makes severe wrinkles on standard A4 - 80g sheets. Do you think a correct fuser-roll lubrication (whith regular fuser-web action) could solve even this wrinkles problem?

Thanks again and sorry for my awful English.
Marco.

[Marcotoshiba]

OK!
today i have resetted the counter explained by Scott Lewis

Now web solenoid works fine (one shot every copy) .
I made about 1000 copies before to leave my customer without any wrinkles or any other problem...

I hope the problem is fixed.
Thanks.

One of the things that can cause wrinkles on copies is not entering the fuser smoothly. A slight build up of toner on the metal plate that enters the fuser can be the cause.

[Marcotoshiba]

Thanks for your tip about wrinkles.

At a moment the problem does not still exist, but in case of wrinkles will occurs again, i will consider to check and well clean the fuser metal input-plate.

Best regards,

Marco.
