I Have a C451 which is producing a loud noise and there are two bands running throught the copy/print top one is greenish and bottom one id magenterish even on black copy/print.
I thought it must be a transfer belt prob so repalced it but still exactly same prob - HELP
As its very noisey Im thinking it may be laser unit but that exspensive to replace on a hunch. It still copys/prints but looks very grainy/washed out.
I HAVE ATTACHED SCAN OF A COPY FROM THE MANUAL

If it sounds like a router going through plastic then check the transfer belt cleaning unit drive gear (machine side not on the unit). I have just replaced my 3rd set of these. There is an updated gear, bracket, shaft and spacer to improve the reliability of this unit.
And Star Trek was just a tv show...yeah right!
What Mr Spock said.............
You dont have to have the part number for the new gears buy any chance?
TABT0900054EN00.pdf From the bulletin
Top Work Chaps - have the gears on order, is it easy to get to the motor.
Do you have both service manuals?
Yes got the manuals - Athough I actualy sell develop machines these days
We are also a DEVELOP dealer. You can get a pretty good idea of how to get to the gears from the theory of operation manual.
Good luck.
TOP WORK PARTS FITTED AND WORKING A TREAT - thanks for the advise, ever need any help with the older Canons, just let me know.
