After cleaning roller my printer still jam the A4 papers

I don't know what make or model printer you are working with but all printers have one thing in common. They all have feed rollers that wear out. If you have cleaned the rollers with simple non-ammonia based glass cleaner and it still jams, time to replace the rollers. If you have replaced the rollers but it still jams, get a stiff piece of plastic the size of letter/A4 paper, remove the paper tray and push the sheet up through the feed roller/registration assembly to force any shards of paper out of the paper path. If it is happening in the fuser area. check the rollers in the fuser to see if they turn freely.

Good luck

Hi Rosa,
There was a paper jam and you cleared the jam, however you missed out to do one other thing. Cleaning the Rollers.

If the Paper Feed Roller is dirty or paper powder is attached to it, paper may not be fed properly.
In this case, clean the Paper Feed Roller. Cleaning will wear out the Paper Feed Roller, so perform this only when necessary.

You need to prepare: three sheets of A4 or Letter-sized plain paper

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

2.Open the Paper Output Tray gently, and open the Output Tray Extension.

3.Clean the Paper Feed Roller without paper.

(1) Press the (Maintenance) button repeatedly until b appears.


(2) Press the Black or Color button.
The Paper Feed Roller will rotate as it is cleaned.

4.Clean the Paper Feed Roller with paper.
(1) Make sure that the Paper Feed Roller has stopped rotating, and load three sheets of A4 or Letter-sized plain paper in the Rear Tray.
(2) Make sure that b appears on the LED, then press the Black or Color button.
The machine starts cleaning. The cleaning will be completed after the paper is ejected.


This should fix the issue

Without doing a complete disassemble, remove all covers, remove paper tray(s), remove ink cartridges (or laser cartridges...everything that is EASY to remove. Clean your rollers (may be gummed up a bit), remove all dust, dirt, grime, everything. My Canon printers are extremely sensitive to jams. As long as you keep it clean internally, you should have no problems. Take a look at this video about paper jams.

Clean the pickup roller with a damp cloth, check whether transfer roller under toner cartrige rotates freely. Check if the size of the loaded paper is the same of the document in the application, i.e. if you print on A4, your document should be set to A4. Sometimes you may receive a document by email with different paper format from what you expect. Reformat the document as setting the page size to your loaded in the printer one.

Good day, I will give you the procedure how to clean the roller or canon pixma mp160.

Clean paper feed roller

There are rollers that the paper has to go between to be pulled forwards. When the rollers get dirty with paper dust, paper starts jamming. So you need to clean the rollers with a moist (not wet) soft cloth, Keep rolling the rollers manually and keep cleaning them. Then allow a few minutes to dry them up. And no jam after that.

1. First, clean your printer. Get some spray-n-wipe cleaner and a clean cloth and clean the entire inside of the printer. Also ensure your paper isn't dirty. Now print a test page. Does the symptom persist?
2. Remove all jammed paper. Check the paper tray first. Look closely at the paper rollers nearest where the paper exits the printer; this is a common source of jams. If you’re trying to print labels, they will often jam just before exiting the printer.
3. Try to print a test page. Does the printer still jam? If you can find no source of the jamming, check the printer's message display window and refer to your user’s manual to look up the printer error code.

Hi guys, I eventually found a solution to the problem for my printer. With the top cover open, I pushed a sheet of 120 micron thickness A4 clear plastic binding cover through the exit tray as far as it would go to rest against the bottom row of rollers. I switched the printer off then back on again and as the rollers lifted momentarily, I pushed the sheet of plastic as far up through the machine as I could before the rollers went down again - it went in a fair distance. The printer then ejected the plastic sheet. I then put the plastic sheet into the paper tray and tried to print a blank document page. The plastic fed through cleanly and my printer has been working since without any error messages. I hope this works for you.
