when machine start to print the first copy, half way , the error code F2-00 appear. then it stop. (the first copy reach the drum and half of it is printed.) what could be the problem????

I would check the toner motor and the toner roller. Make sure toner motor is turning. I would check the toner roller especially if the copies are really over toned. It is a foam roller and in the bottom of the toner hopper, if the end of the roller is worn, you will know it.

Here is a photo of probably what your going to find. I have run across this as well. Messy job. I took a few peices of 11x17 paper, taped them together and dumped the toner onto that after cracking the tank open. Vacumed it out the best i could, changed the roller and problem was solved. Our machine would always get very low TCS readings and as the problem progressed the DV was so over toned it was dropping toner onto the paper as copies were made. The easier fix is a new toner hopper but the price difference probably won't be easy to justify.

I have replaced the toner roller recently.(i have already clean the toner hopper unit and checked it and i am very sure it is in good condition)but when i execute sim 25-1, the deve reference reading goes very low, the reading is around 30. and the print out density is good( normal density). could it be the developer itself problem?(it is a used machine, so i have no record of the last dev replacement)

Possibly, I would clean or replace the ATC sensor when changing the DV.

ATC sensor. is it the one which is on the dv tank?

On a machine this old, I would also look at the mag roller for seizing. When it starts to seize, it will break gears in the main drive, so you won't hear any unusual noises. The developing unit just loses drive. If you replace the main drive only, the same gears will break in a few weeks (until the developing unit is replaced). =^..^=

Another thing to look at is if it is leaking DV. It will usually leak DV through the bushings where the Mag roller sits. If it is replace the bushings and clean the shafts where the bushing sits.
