Question about Canon PIXMA MX310 All-In-One Printer

2 Answers

Thickness lever The printer keeps asking to check if the thickness lever is to the left. It is but I still can't make a copy of anything, even a regular 8.5 X 11 sheet. I followed the instructions to the tee but to no avail. Is the printer defective?

    This is the most frustrating machine I've ever dealt with. One error message after another and I'm not even thru initial setup yet. Now I get the "check thickness lever" message even though it IS already set to left. Anyone out there have a solution?

I just bought one of these printers and got the same message when trying to print from my digital camera... All you have to do is press the OK button on the printer!!! Don't feel too bad.. there is no documentation that explains this.. I only found this after I started frantically pressing all the buttons on the printer out of frustration.. Good one Canon.

Printer will not function. paper thickness message i550


Thanks for using FixYa. To resolve the issue of paper thickness message you’ll need to turn your printer on and open the lid and there is a small blue lever having two positions, left for regular paper and right for envelopes.

Please do rate the solution and revert for further assistance.

Will not print and keep getting paper thickness error

Did you try moving the paper thickness lever (blue lever on top of the print cartridge holder)? It should be all the way to the left when you start--if it needs to be adjusted the printer message will let you know.

Printing envelopes on HL4040CN

I just bought a HL-4040CN and all my envelopes wrinkled, regardless of the size, paper thickness or software settings (thin envelope, thick envelope, etc.). Here's how I solved the problem....Open the rear panel and you'll notice a small gray lever on each side, which is probably pointing to "A" on the scale (A, B, Envelope). Move both levers to "Envelope" and close the back panel. The troubleshooting manual says the levers should be moved back to "A" after printing the envelopes, but I left them in the Envelope position and can't see any difference when printing regular or test pages or envelopes, except the envelopes are no longer wrinkled. I called Brother and asked them if there was any reason why the levers can't stay in the Envelope position, and they told me they could be left there if it wasn't negatively affecting other documents. Now, I have a great printer that prints everything without any problems. Hope this helps.

The Paper Thickness Lever should be set to the left for normal/plain paper. This switch can be seen inside the unit in the area of the paper output tray.

Printer won't print

I know that the paper lever is where your paper is loaded. Check the grey plastic tab and try to drag it to the right or left. Depending on your paper size you might have to check the owners manual.
