I have a bizhub C450 and i am getting a yellow line at the top of my printed page and also 2 pink/red dots in the middle of the page. How can i stop this?


The yellow and magenta image units may be the problem. Yellow may have worn out on one end causing the yellow line. If the pink dots show up on every page but move around from page to page, there may be damage to the magenta image unit. You can remove the image units from the machine and look at the drums (long green cylinders), this should be shiny and clean. If not, you may need to replace.

What error code.
Toner sensor's are usually at the far end of the Toner Cartridge. It will have what looks like a connection, silver or bronze wire, or a chip look thing, if it is dirty it can cause error codes as it is not making contact with in the machine.

Konica c6500 c-2451 error


C-2451 - When the developing motor/Y
(M20) is ON, the maximum
detection value of TCR sensor/Y
(TCRS/Y) is the specified value
and the difference between the
maximum detection value and
the minimum detection value is
over the specified value.

relavant parts:
Printer control board (PRCB)
Developing motor/Y (M20)
TCR sensor/Y (TCRS/Y)

- first check that the motor is turning correctly, clean sensor, check toner pipes, that the toner is rally moving from hopper to developing unit.

i think that your fax is not set up right, or maybe the machine is missing admin and machine e-mail address, that can cause too this problem.
