Code C-OF34 on Biz Hub 350

After refilling the cyan toner in the Bizhub 350 we started getting this error code on color print jobs. B and W print jobs run fine. But, when you run a color job the printout is delivered but the system throws code C-0F34. The door has to be opened to clear the code and then you can print again (one sheet at a time). Any ideas?

SOURCE: bizhub 350 error code

c3852 means low fuser(hot section) temp setting. hold down utility or stop key, then you should be abel to do trouble reset. if problem persist it would most likely be a lamp or a sensor, which will require a technician to come out.

SOURCE: biz hub 250 Pdf printing problem

Hi I am former Konica Tech Support for 26 years. I do some network problem. Y may need to upgrade the copier memory. or this just simple setting. on the printing side I can assure you no problem. there is a setting on the operation panel choosing if you prepared pdf when ever you to e-mail, scan to box or scan to SMB. You can delete the old print driver and the control panel delete your even the printer Icon at the printer and fax folder. Re install the printer and the printer driver. And make sure send a test print. If so happened that you don't have the print driver you can go to Konica web site and download the print driver. There are many kind of print driver. postscript driver and etc. I hope this info will help you and if not you may contact me again.

SOURCE: Biz Hub c250 gives error code 3452

C3452: Pressure Heater Trouble.
Try to reset it like this:
Shut down from the main power switch (the one behind the front cover).
Keep pressed the Utility/Counter button.
Power on while the button is kept pushed.
Release the 'Utility/Counter' button only when you see the 'Trouble Reset' button on the touch screen.
Touch the 'Trouble Reset' button, a small ok should pop up underneath.
Power off, wait for a few seconds and then power on.

C452 only cyan not printing and coming up with c2551 error.

I have a customer that does not print much color and the color toners end up settling into a lump at the back of the cartridge and then it throws this (or other color TCR) errors.

Its a once every 6 months deal, go in, shake the hell out of the toners, get the machine to recover (TCR toner supply i think the button is called) and away it goes till next time.

Biz Hub C250 - code error C2551

Ahhh, you must be the same Macdaniel I emailed for clarification a short while ago.
C2551 relates to the Cyan imaging unit, the machine thinks the toner level inside the Cyan imaging unit is low.
Opening and shutting the main front door is the reset procedure. However if this doesn't work you should try the following
Remove the Cyan imaging unit, give it a bit of a shake and then refit.
Experience tells me that the above only works on occasion and you will probably require a new imaging unit. They are available for around £250.
Please be aware that the fault could also be down to a circuit board being defective, but this is less common.

Biz hub C252

YOU CAN RE-TONE THE MACHINE BY ENTERING SERVICE MODE SELECTING IMAGE PROCESS ADJUSTMENT AND TCR SUPPLY SELECT THE COLOUR THAT IS DEFICIENT AND RUN THE SUPPLY JUST ONCE. BEFORE YOU DO THIS CHECK THAT THE SEALING STRIP ON THE TONERS HAS COME AWAY AND NOT STUCK OVER THE HOLE HENCE STARVING THE MACHINE OF TONER.
