Paper size when i want to make a copy the machine keeps on asking for letter paper in bypass tray,but it an A4 page. when i scan to my pc using ftp it cuts off at top of the page.

Did you trying hitting an Ok button, green button, etc to confirm legal size paper, maybe it wants you to confirm paper size. Also legal is 8.5x14, did you select legal or enter the size as a custom page?

Sounds like someone requested A4 size paper in a print job instead of the normal Letter size paper...
Try putting regular letter size paper in the bypass tray and then set it up as A4 size...the print job should then print out on that paper.

Two possible solutions to your problem.
If you are talking about grabbing more sheets than one from the tray, you need to make sure the tray guides are up flush against the paper.
If on the other hand you are talking about scanned/copied jobs, check the setting for your scanner, it may be set to letter size which is longer than A4, so the machine thinks it needs another sheet to complete the job causing a blank page to be sent.
Hope this helps

Someone has told the machine to either make a copy or print from a PC to the Bypass feed tray on the copier. If you are not trying to print something by using the bypass tray then just turn the machine off, then on again to clear the request from the copier. If you are trying to print or copy from the bypass tray then simply insert the correct paper size and direction into the bypass tray slot and the machine should automatically begin printing.
Good Luck and Thank You for using Fixya.

Check the display carefully, is it waiting for a different size to be supplied, or is it waiting for apaper to be loaded into the bypass tray

If you attempt to print/copy to a size not loaded into the machine, they will wait for the requested size. (depending on your optional menu settings)
This is especially a problem if you eg. try to print A4 size, and only have US legal or US letter loaded into the machine, and visa-versa.

The computer has sent a A4 size document to the printer and the printer is asking you to put a A4 size piece of paper in the bypass tray so it can print it. It may be an email A4 size that someone has sent you or check the settings in Microsoft Word print or page setup to see if it is set for Letter size, not A4 size.

A4 is n earupean size .change to 8 1/2 by 11 in both the copier and you printer setting..

check your settings on tray one. make sure the you set it to 11x17 by the way what is the model of your machine? don't set the machine to auto detect paper.

hi im jules_09.have you set the paper size first before copying.there is nothing wrong with adf its fine.if you want to use fls go to the program then set the size of the paper and which tray you are going to use each paper tray can be adjusted according to your paper size needs

Are the print jobs being sent to printer all the same page size?

Are they all print jobs sent letter page size and your printers cassettes are set for A4 or something?

Your printer is asking for letter size paper, because any paper it has is not set to letter  and document that it is trying to print has been sent as that size.

Check what options you have on print driver on pc as far as Tray defaults, paper type and size settings

Check printer settings via its keypad as to tray defaults, paper size set for each tray and paper type, some printers have paper size switchs on their trays too.
