MPC7501 toner dropping. Like this hasn't been covered a thousand times before!

This may make you laugh, and possibly deserves to go in the rants & rave section, but who knows.

So, we're all aware these machines are lemons, and keep us pretty busy. But yesterday our national service manager (who of course has never been a technician) has laid down a challenge. The technician that finds a fix for the toner dropping issue wins $2000.

Now, I've been working on these since day dot, and I've tried all sorts from leaving gears off & leaving the springs off of the lube bar to adjusting the Vtref and toner consumption rate and everything in between including vaccing out the machine & filters to within an inch of its life and changing parts well before supposed life.

So far my response to his challenge is "See that big red button there? Turn that off!" Along with "If theres
a fix available for these machines, surely we'd all know about it by now!?"

What magic fixes do you use & what excuses/reasons do you give your customers that you see them on a regular basis for the same thing?

Can I get a peice of that $2K?? Here in the midwest we've been working on the drum ground problems these have. Tried new drum shft bearings and shafts. Fabricated metal ground plates that mount on the drum flange plate and contact the front side of the drum shaft seams to help. Ricoh knows about the problems but thier intel has been unofficial.........

Sounds interesting! Do you have any plans or pictures of these mods?

I've always felt its a charging issue, but with regards to the type of environment it's placed in. Generally, the smaller the room and the hotter the area it's in, the worse the issue. I've so many of these in my patch, some worse than others, and the most clicks I've had between visits is 100k in a month. I've had some success with lowering the toner consumption and adjusting vtref, but hasn't worked on all and is a bit of a balancing act with CQ.
