Multiple pages the machine is taking in more than 1 page at a time when sending a fax. Is there a roller that needs to be cleaned or replaced?

IF IT JAMS OR TAKE ALL THE DOC AT THE SAME TIME CLEAN OR REPLACE ADFRollers and separation pad. TEMPORARY SOLUTION IS use sanded paper gently to give surface of roller and adf pad, moer grip

Have you checked that you have no paper jams?

If you have time and small amount of skills do the next:

Open cover of keyboard panel ( pull towards ), then you will be able to see, on fax side two rollers, and on keyboard side one separation assy ( rubber piece grey or black color ), as first aid use mild sand paper and "scratch" on it and clean with alcohol.
Also clean the rollers on fax side, while turning them.

This is only as first aid. If then works, that means that you need to order and replace separation assy. For EU code is HG5-1308-000.

TIP: when you replace sep.assy, also tighten the spring wich holds separation assy.

Clean the rubber feed rollers and the separator under them (the area below the feed roller that is supposed to hold the next page in place when the top one is fed.
Sometimes the roller is on the bottom, and separator on the top, depends on model.
Use a lint-free cloth dampened with isopropyl alcohol or at least dampened really sparringly with water + washing-up detergent.

Open up the document feeder and clean the roller and pad with alcohol.

There is a separation pad under the feed roller,that pad needs to be cleaned or replaced.If you open the fax and remove the cartridge,inside at the back were the cartidge was you will find a roller,cleen that roller.Under the roller there is a strip of rubber-the separation pad.Take a ruller cover it with a cloth and use it to clean the sep assembly under the roller.If the problem pressist the sepparation needs to be replaced.

look for a piece of paper in the paper path. clean all paper feed rollers

Open the document feeder (number panel). Make sure that a switch actuator is not stuck down.

~When sending one page, does the display indicate usage of any memory ? If it does then it is merely a feeder problem. If you open up the front flap (the whole panel holding all the number keys and display it hinges forward) you will see to the rear of the machine two rubber rollers - the rubber 'goes off' after a bit - it either dries out/ perishes or gets dirty. You can try cleaning these with a slightly damp rag (avoid paper towels/ fluffy cloths). However, if they have gone past their use by date you may have to consider replacing your machine (unless a proficient engineer can replace them for less than the cost of a new machine). Whilst the front flap is open, below the lower of the two rubber rollers is a glazed screen which houses the scanner. Run you finger across the glazed area and see just how much dirt is being scanned across each of your pages being sent - you might be surprised!

In the meantime, this is not an unusual situation - but do you really have to send 80 pages of fax (5 - 20 I can understand)? The risk of missing one page (and it being a crucial one is too great). However, my L350 will not pickup following pages and is much happier sending single pages only. The only solution, I am afraid, is for you to stand over the fax and feed one page in after another, just as the previous one leaves the input tray. You can keep an eye on how many pages have actually scanned and if it matches up with how many you have fed through by keeping an eye on the page count on the machine's display.
Can't offer a better solution i am afraid. hope this helps tho.

most likely the seperation pad has worn out and possibly the roller parts sould be still avalible for this model. besides replaces the worn parts in the machine there is no quick fix besides cleaning the rollers and the seperation pads in the machine with a damp soapy cloth with like dish soap and wiping dry with another cloth it might work better for alittle longer or till you get replacement parts.
