Canon DR9050c: Is double-feeding very frequently despite new rollers (consumables). Only three years old. Problem is new. Has been working well up to this point.

Hello -

From Support information I found on the Canon website, the paper feed rollers of your PIXMA iP1900 may need cleaning.

The feed roller cleaning function allows you to ckean the paper feed roller. perform feed roller cleantng when there are paper particles sticking to the paper feed roller and paper is not fed properly.
The procedure for cleaning the feed rollers is as follows:

1.Prepare the printer
Remove all sheets of paper from the rear tray.
2.Open the printer driver setup window
3.Click Roller Cleaning on the Maintenance tab
The confirmation message appears.
4.Execute paper feed roller cleaning
Make sure that the printer is on and click OK.
Paper feed roller cleaning starts.
5.Complete paper feed roller cleaning
After the rollers have stopped, follow the instruction in the message, load three sheets of plain paper into the rear tray, and click OK.
Paper will be ejected and feed roller cleaning will be completed.

Best wishes.

The only thing I can think of, without actually seeing it work, is the feed rollers. I've never liked the feed system on this model, seems to be very temperamental. It could also be the feed clutches. There was a modification that should have done years ago dealing with the feed system. I don't know if this applied to the extra two cassettes but the two upper paper pick-up assemblies were to be replaced. Gears were updated.

If this is a Canon CR-180 or 180II machine then the feed tires need to be replaced. Often if you are using the grey feed tires, the middle one will come loose from the platic hub and cause this problem no matter how much you tighten the tension wheel. The part numbers of the seperatrion roller assembly and the feed tire assembly are as follows.

MG1-3530-000 Seperation roller (has 3 tires)
MF1-4210-000 Feed roller (has 2 tires)

You can also replace the two in the hopper area, they are:

MF1-4352-000
MF1-4353-000

That is a common problem on older machines; hopefully that helps

Please see this solution from Canon. It is recommended you check your manual for the proper procedure for clearing paper jams. Incorrectly removing jams could damage your printer. Trust the following helps resolve your current issue.

Issue: More than one sheet of paper feeds while printing


Solution: Clean the paper feed rollers using the MX300 operator panel

Cleaning the Paper Feed Roller (Roller Cleaning) Clean the paper feed roller if paper is not fed properly. Cleaning the paper feed roller will wear the roller, so perform this only when necessary.

1. Make sure that the machine is turned on, and then remove any paper from the Rear Tray.

2. Clean the paper feed roller.

(1) Press the Menu button repeatedly until MAINTENANCE appears.

(2) Press the or button to select ROLLER CLEANING, then press the OK button.

The paper feed roller will rotate as it is cleaned.

3. Repeat step 2 twice.

4. Open the Paper Output Tray.

(1)Put your finger in the rounded indent beside the Paper Output Tray and open it gently.

(2) Open up and set the Output Tray Extension completely by pressing down the hollow on its front side.

5. Make sure that the paper feed roller stops rotating, then load three or more sheets of A4 or Letter-sized plain paper in portrait orientation in the Rear Tray.

Set the Paper Thickness Lever to the left.

6. Repeat step 2 three times.

The paper cleans the paper feed roller as it feeds through the machine.

If the problem is not resolved, wipe the paper feed roller (A) located on the right side inside the Rear Tray with a moistened cotton swab or the like. Rotate the roller (A) manually as you clean it. Do not touch the roller with your fingers; rotate it with the cotton swab.

Double printing or double feed??. Double printing means document printed in 2 copies. Double feed means printer feed double paper in one moment. For double printing,please check number of copy of document in printing preference properties.
Double feed occurs when pickup roller fails to pick the paper correctly. It's usually caused by shaft of paper pick up roller which is broken. You should replace drive assembly (include pick up roller) in this case

You can see the feed roller by opening the door on the lower right side. The copier will try to print with this door open. Steven 805-520-3003

On this machine, the feed rollers might be worn down.
Not seeing the machine and by the description. there can also be other possible problem areas, deep in the machine itself.
Does the paper feed partially out?
If it does not, are there paper black scuff marks where the rollers were trying to feed the paper.
Can you hear the solenoids feed the paper?
If the paper does feed and seems crooked, it is possible the paper tray springs need to be stretched out just a little to push the paper tray plate more on the feed rollers.
Make sure the tray is completely up in the latched position so the feed wheels will touch the paper stack itself.
If you have a two paper tray, make sure you tell the machine what size paper you have for each tray.
Run paper in each tray.
Good luck.

The exchange roller kit has all the tires that pick up the paper in the kit (feed, separation, and pick up tires). I think the other tire you are talking about is just one tire not the set.
Also check to see a switch on the scanner that is used for single feed or multiple feed. If its on single feed it will multi feed all the time. You can clean the tire with rubbing alcohol too, to see if your double feeding goes away.

Have you still getting the problem, have you done cleaning of Cartridge, its nozzle and Contact strip.. then cleaning of Printer roller or carriage rack.. Do a Service of it or get it done by Technician.

Also check the feeder tray.. to grab paper one by one by printer.. Manually

Take all updates for printer and OS.

The only suggestion I could make may be obvious but my experience has taught me that you need to make sure the paper is installed correctly, especially with double ply paper. We have learned that the yellow receipt copy ply must be attached properly to the green roller so that the double ply paper from the roll feeds correctly through the print roller. Also make sure the double ply roll paper is not loose coming off the roll that feeds to the print roller.
