Hi i just bought a second hand konica minolta c350 and when i print something it is notting enough clarity. please anybody can help me .

I would first starts by removing the Imaging units that are locked with blue levers below toner cartridges one by one for each colour and use the cleaning tool that is provided on the door (metal rod with handle and a pad on the opposite). When you pull the Imaging unit all the way out, you will see inside a long strip of LED and next to it on left hand side about a 1-2 cm another strip of MICRO LED Array. This is essentially yor print head and it has to be spotless clean. Use the rod and padded end to clean each of the arrays. This will give better sharpness and clarity to your prints. Then put Imaging Unit back in machine and pull the blue stick from the Imaging Unit out-in-out-in. The next step is to do Stabilisation and Gradation adjustments. This can be done in Service Mode. This should improve your printing. If it doesn't then you have either worn Imaging units _or_ Transfer Belt _or_ incorrect settings on Fuser or Fuser being worn.

How do I replace rollers that are too slick to feed paper properly and from where can I purchase said rollers?

The rollers may have become glazed from feeding particular paper stock. Your machine may be old enough that the feed rollers are simply worn out. Finding replacement rollers could be difficult, especially if the machine is so old it no longer is supported.

What can be done to fix my fi-6670?

You may need to lubricate the moving parts. I had a printer that was playing up like this and the bars that the print head moved on needed a tissue with a small quantity of machine oil to be rubbed on the bar to allow the print head to move freely. If all the scanners are the same age the lubrication they had may have worn off.

Scanner runs loud not smooth

I have many years experience with Canon scanners and I do have some suggestions for you.

The only time I really experienced a loud scanner in that model was if if the rollers the smaller black ones were not spinning freely causing the paper to drag to the machine. That usually was caused by a gunked up bronze bushing the rollers sit in. When you open up the top half of the scanner by raising it up and with the power to the scanner turned completely off. You should be able to spin the small black rollers freely by hand by just passing your hand over each one. They are mounted on a shaft and and each set of 4 or 5 black rollers are mounted to a single shaft.Try spinning them if they all spin freely then your problem is with the lower rollers.

Again with power completely off try pushing on the black rollers on the bottom by hand. You will feel some resistance with these rollers because there are gears mounted to the end of these shafts and they are belt driven. They wont spin as freely but should spin with some resistance and if it is the problem your having with loudness you should here sort of a metal on metal sound that is telling you one of the bushings is worn out. If you dont hear any sounds then your problem is probably with the main drive motor that propels these rollers. To get at that motor you will need to remove the back cover first and then the right hand side cover because the motor is on the right hand side as you are facing the machine as if you were going to use it. The fix can be as simple as readjusting the tension on the main drive belt by loosing the screws on the main drive motor pulling the motor back until you have more tension on the belt and then tightening the screws back on the motor. Or it can be the motor itself. You will have to remove the screws that hold it in place and then slide remove the belt and slide the motor out towards you. You will recognize this motor because its towards the back of the machine, silver in color, with one small electrical connector mounted to it and its round about 3 to 4 inches in diameter. Once the motor is out try spinning it by hand to see if it is binding. Also once it is out now try spinning the bottom rollers by hand to see if you get a metal on metal sound because they will spin much more freely now. Once you determine which one of the items is causing your loud noise then contact your local canon dealer for the replacement part or you can even try looking on Ebay there are many parts for sale for your scanner its a popular model still today.

I hope this helped you out and if not let me know.

Scanner won't pull paper in - belt problem

Are you sure the belt is off?
To remove the side covers you need to remove the back cover, then the top cover. You will notice a small 'catch' on both sides of the side cover. You need to release to open the sides.
