MX522 will not print when doc's are fed in using ADF. A blank page is ejected.


Are you feeding the page through upside down?
Most ADF Units require the page to be writing side up as they loop over the scanner and feed out with the text facing down.
Check the ADF Tray as it will have a picture showing how the pages are meant to be placed to be fed through the ADF.

Bizhub C652 has horizontal lines.


its important to find out whether the \'lines\' are in scan direction/ or only through Radf or only from scan glass,

if the lines are only showing when documents are fed throught the Radf, then the problem lies with the document scan plate( left of the main glass platen (about 2" in width)) or with the scan plate blade cleaner

if the lines ONLY appear when copying from the Glass then the issue lies within the optics (probably nothing more than a clean will be needed)

another question would be to ask if the lines are solid (black line overprinting image) or if they are \'missing\' lines where the image has failed to copy, sometimes it can be hard to work out which side the fault lies,so try shaded greys as a copy original .

if the scan lines are appearing on both Radf and Glassplatten ,mode then the issue may be dirty optics/ccd sensor or it could e an indication of the ccd failing or image control pwb in error while interpreting the image file.

what to do

1) place a grey sheet of paper in the Radf and have the copier photocopy both sides of the original and print to single sided sheets ( so the printer turns the original over to complete the task)

observe the result.

2) have the copier photocopy directly from the platten glass- single sided.

observe the result.

ckeck to see if the error has appeared on both sets of prints ,

if the error has only appeared in the first set of prints then the issue may be a tiny DOT on the slit glass (left of platten) - a dot on this glass will indeed appear as a Line as the original is scanned across the glass.

hhope thhis helps

Like many other people I have a vertical line down the copy, using the document feeder, not the plate glass. on my HP officejet J5780 3 in one. Your advice is to clean the small glass plate. I look...


I dont have a picture at the moment but if you lift the document feeder up to expose the large plate glass, the small plate glass is normally situated at the extreme left hand side of the large plate glass.

When I copy there are black lines across the page. I changed out the cartridge for a new one, but it still makes the lines.


Lift the copy bed cover and locate the **** glass (it is about 1" wide and sits on the left of the large glass)

Use a microfiber cloth, and a bit of water, and remove the debris from this **** glass. Make sure it is clean, then clean the white bar on the underside of the top cover (It will sit on that **** glass)
take a blank piece of paper and copy it through the feeder, if you have lines on the page that prints, you need to look harder for a spec on that glass. a small dot will create a line on any document fed through the feeder. A dot on the large glass will print only the dot as the paper is not moving over it.

Original document fed into top feed tray of mfc 7440N model come out with few thin black lines on the mid left of the scanned file. Scanning file from glass has no issue.


You need to clean the narrow glass strip on the left side of the machine when you open the cover. There is likely lint or something on this glass. This is where the auto document feeder pages are "imaged".

Prints fine,1/2 in black line down the side when we make a copy.


Try this (one of many troubleshoots)

There are TWO platens with the ADF models.
One is the obvious glass plate (bed). The other is a strip of glass that is almost an inch wide. This stip is where documents fed through the ADF is scanned. Chances are, this strip is dirty. Take a damp clean cloth and wipe it down. I use isopropyl (rubbing) alocohol and do a quick swipe to loosen ink, gunk, adhesives, etc. off of the glass and finish with a dry cloth.

Hope this helps!

It defiantly sounds to me like the optics are to blame, if you remove the platen glass you will be able to clean the optics very gently with a glass cleaner just to pull the dust particals off :)

Black line when aoto fed document prints


Hi,
If you lift up or open the auto feed you should gain access to a small **** glass underneath the autofeeder. Clean that glass with alcohol or some other glass cleaner. That should clear this up.

If any debris get on that glass the result is dark lines caused when the page travels over that part of the glass. Hope this helps. Let me know.
