"Cannot Adjust Fusing Unit"

I have recently replaced my fusing unit. Upon powerup with the new unit I tried to run the fuser adjustment procedure. It started and after a few moments failed. I entered the Maintanence menu and tried to run the fuser adjustment and I got the message "Cannot Adjust, See Manuel". After looking at the manuel it said I had to make sure I had plenty of toner, so I put in all new toner cartriges. Still no luck getting the fuser to adjust and even my IKON guy was confused. Got any suggestions.

    J, I may have a problem with the HP sensor. Would the printer continue to work if I had a defective, dirt, or blown fuse on the HP sensor?

Hi there set the transfer belt into the home position then power on this resets the transfer home which then allows calibration. Tray this if not replace transfer unit.

Thanks J

    Try cleaning the HP sensor with a blast of compressed air. It should continue to work but you will get a SC code every now and then also the machine will not be able to calibrate correctly.

    Cheers J

Ricoh mpc3500 fuser unit setting error

Most common problem is the electrical connector on the fusing unit or the connector that the fusing unit connects to inside the machine is broken. So when you push the Fusing Unit in to the machine the connector moves out of position and doesn't connect properly.

Fusing unit is not set properly

turn the printer off and reinstall the unit after it has cooled off (30 minutes). Then open cover B and D. Remove the fuser unit, then reinstall it properly. Close covers D and B. The error clears automatically if the fuser unit is properly installed.

If the error is not cleared, the fuser unit is out of order. Replace it with a new fuser unit.

if you already replace PCU still produce line on copy it could be fuser roller found at fusing unit. if black lines replace fuser unit or if available fuser roller much better but if white lines just clean laser unit. another problem may contribute might be deform frame of scanning section includes mirrors and alignment of lens unit this problem occur usually upon transport of the machine.

Generally, when you have a ghosting problem, the issue is with the fusing unit. If you have a new fusing unit (or if you can get one) install the new unit and the problem should go away.

If you don't have access to a new fuser, you can try replacing the drum/imaging unit. Sometimes a ghosting problem can be caused by a bad cleaning unit (inside the imaging unit), but usually it's the fuser causing the problem.

Unfortunately, on the AP3800C the oil supply unit is part of the fusing unit. However, you can purchase just the oil supply portion of the fusing unit and replace that (part #G0604022).

I'm not sure how much that would cost, but it's got to be cheaper than a whole new fusing unit.

Canon IR5000 not running 20 lb. will run 60lb. and cover. 20 gets stuck in middle

If it's getting stuck in the Middle , I am assuming it's getting stuck right a the fusing section, Ok if it is running 60 lbs of paper greatly but, jams in the Middle , this tells me your fuser needs to be adjusted, This is something you don't want to do if your NOT a Service Technician most likely if your fuser was adjusted for 60lb paper the temperture was also adjusted so the paper won't be too too hot, I am certain your fusing unit will need to be adjusted or the Upper fuser/Lower Fusers are worn. Yea, you'll have to call a indiepent or an authorized dealer for this, unless you know how to rebuild the fuser yourself- be careful- this is exteremely hot unit.

Even though u can check the lamp by removing back cover and turn on the machine u can observe the light of fusing lamp
