Hello!
Why did you change the fotoconductor Unit???? This part of the machine is to create the image.
Your problem is in the tray. Meaby a broken switch. Take out the all tray and look inside to see if there is same obstruction.
If you do not see anything i advise you to call a Tech.

Dont waste more money if you dont know what your doing. This is the best advise i can give you.

See you!

Most of the time the motor in the laser unit has gone bad.
The laser could also simply need cleaned.

When the machine stays at the "Please Wait" message and nothing else happens, the most likely cause is the hard drive. The hard drive will need to be replaced in order to restore full functionality. You can disconnect the hard drive to make the machine work in the meantime, but you'll lose some functionality.

sc363 is a yellow PCU error. Try replacing the toner cartridge and resetting the PCU. If the error comes back, you'll probably need to replace that yellow PCU.

No, you can't reset. You'll need a tech. Here's what the manual says: Symptom (SC101) - Exposure lamp error - The standard white level was not detected properly when scanning the white plate. Possible Cause: ? Exposure lamp defective ? Lamp stabilizer defective ? Exposure lamp connector defective ? Standard white plate dirty ? Scanner mirror or scanner lens out of position or dirty ? SBU defective

You could remove the color and black&white drum units and check from below the units to visually observe lines on all the 4 drums. If so, you have to change the drum unit/units. Drums occassionally get damaged before life this way due to solid toner particles inside the toner bottle.Always "shake the toners very well" before replacement, and if you print rarely, then remove the toners and do the shaking to prevent clogging due to inactivity.

I guess by your fault description that there is a blank gap before the printing starts? The only way to cure this problem is to replace the registration clutch as it is turning on too late and not releasing the paper quick enough. Also check that the paper tray dial is displaying the correct paper size and position.

Thanks Jason

Sounds like you need a new cleaning blade. It is located inside the process assy behind the drum.
