The default setting for 6x4 photos is 100mmx150mm paper. If the machine does not detect paper that size or has not been told where to find it, the machine will report a paper fault. Refer to the manual on the CD that came with the machine esp Ch2 P14 and Ch4 P22 for help in this. If you don't have the CD you can download the manual from the Brother Website.

Load Legal paper in Cassette 1.
If you want to print using only one piece of paper currently loaded in the Manual Feed Slot, click [Resolve Error].
If you want to feed paper from the cassettes, remove the loaded paper from the Manual Feed Slot.

Hi,
do you mean CHECK DOCUMENT SIZE?

If yes, check the paper size slider in cassette, check under printer properties custom paper size, it should state the paper wich is in cassete.

I put the 4x6 in the bottom cassette. I place it with the shiny side down. Landscape is when the 6" length is front to back in the tray.

I use the cassette exclusively for 4x6 and use the back tray for all else. It works great.

I hope it helps!!!

which is the model of the printer, not all the printers permite to you do this

Tackler- I dont think I have a solution but I know that the cassette should stick out about 5cm i.e. the cover just fits on nicely. I found with mine sometimes it needed a firm (but not hard) push in as obviously some sensor was not being tripped and it would just not pick up the paper in the tray. Have you tried using the top down feed? At least if that works you can print (and you can stack up a couple of pages).

The problem is that only "fine photo pro" is available when the paper selected is photo paper. Change source to the sheet feeder, hit the "Paper" button and then select normal paper. You'll then be able to change the quality to normal.
