My Brother MFC 9440cn keeps giving a paper jam error message from tray #1 when there is no jam. Looks like paper cannot feed always

not sure if your on copy mode or print mode ..close the MP tray door....turn off then on go to general setup select tray 1. not sure if your on copu mode or print the machine wants you to add paper to the tray that needs it. if you add paper dowes it still say"add paper" .if this is the case then the tray sensor is 1)broke2) pushed out of the way folded3) tray feed roller are not installed correctly no allowing sensor ..make sure your printer settings(properties) are set the that tray.

check the wheels that pick it from the tray.
If they feel smooth, try to put some tape on them and rip it back off.
This cleans the wheels. Also try a new pack of paper and check if it\'s set to plain paper and not to heavier or coated paper

you might try this:

open the back cover for paper jam and check is there any foreign object is present then remove that it and start printing

The paper is not feeding from the paper tray. The loud click is alarming, but not the problem. Check the adjustments in the paper tray. The left and right guides should be snug, but the rear guide should give between a 1/16 inch and a 1/8 inch of free play. If the rear guide is tight, that is the problem. You can check for this by depressing the lever on the right front of the tray. Depressing the lever should raise the stack of paper out of the tray so that it can slide forward.

If you remove the paper from the tray, but will see calibration marks for the paper size you are using. Unlock the read paper guide n the tray, squeeze the release and move the guide ot the mark for the size paper you are using. For example, it you are using letter size paper, the read guide should point to "LTR".

my brother MFC-6490CW keeps coming up with an error message 'cannot print 70' how do i solve this?

With my Brother 8840D I have had paper jams that when cleared would not delete from the display nor would the machine operate until I unplugged the machine for around eight hours. I guess it is a sort of reset or reboot.

When you ready to print your computer.please go to print properties setting paper source default or tray 1 or MP.MP mean multi pass tray.I mean front paper loading tray.

Have you gone into the printer properties and changed the feed tray? If not to do this go to file and then print ( if hit the print button on the toolbar it will just print), beside the printer model there is a properties button, in there near the bottom you can change which tray you want the paper to feed from. Hope this helps.
