Question about Epson Stylus CX7800 All-In-One InkJet Printer

Scanning trouble PLEASE HELP!!!


The scanner light works and it moves. When the page prints, only approx. 1/4" on one side appears. The rest of the page looks like static on a television with colored streaks in it. We have installed it again and tried everything we know. Can you help.
I'm having the same issue - static appears in place of the scanned image. The white areas show where the scanner correctly pics up the image.

Try first reinstalling the scanner drivers, just to ensure it is not a controller problem.

If reinstalling drivers does not fix it, then it is either a lose connector/bad wiring inside the scanner.

Or a fault, like faulty scanner pcb, fauslty sensor, faulty scanner engines.

In both case the scanner must be taken apart and tested by a technician.

If you live in US you can call (800)922-8911 [ press 1 then 2 ] to get support.

If you live in a different country, use the Epson website to get support:

    If you get same problem even doing a copy , then it is definitively the scanner CCD array. That is the sensor that take a snapshot of the picture sliding on the document (see here to find out how it works).

    To fisx this the scanner must be taken apart, and the array replaced.

    Some times the array is fine, and you need to replace or put back in place the flat cable connectors that connects to the array.

    This job should be performed by a techincian.

Hi,

I am afraid that the scanner engine of the Epson CX7800 has sustained a hardware damage. This of course would require a fair familiarity of electronic components/circuitry and safety procedures, use of a DVM and a soldering iron. It would be to your added advantage access to a service manual or at the very least a schematic diagram with voltage readings. Should you be uncomfortable performing a DIY (do-it-yourself), perhaps your best bet would then be to seek the services of a qualified professional.

If you are considering a DIY, pls re-evaluate the cost of repair and the downtime including sourcing of parts. It may be to your advantage to simply replace the unit or request warranty repair/replacement (if still under warranty).

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

    As initially suggested, it is a hardware problem, the scanner engine.

How does it work when you print some file from computer?
Please let us know so that we can focus on one of them...

I wanted t know if the scanner which u r talking about worked correctly
before it had this problem ...........
if yes then there will be no problem with the drivers....
the problem could be either with ur printer

or

with the optical sensors ....

the light getting on or off does not mean that ur sensors are correct ....
try replacing the sensors with some other sensor and see if it is working or not and pls tell if it worked
till hen could u give the Scanners company and model no.

After clearing a paper jam when you print the right side of the printed paper is not as dark as the rest of the page. I have replaced the fuser to no avail is there an adjustment that needs to be made?


Hi there! Wich color is not dark as the rest?Only when you print in black and white or even in the color printing? If the black or any of the colors are not dark as the rest of the page you must clean the led scanners(Wehn you open the top cover you will see long black boxes on the top cover,those are the led scanners) if they are clean then your transfer belt is damaged and can`t transfer the image from the drums to the paper.You can check the belt by starting a printing and open the top cover while the paper is moving under the toner cartridges and look at the page!Please replay what you have seen so i can help you futher!Thaky for usin Fixya.

Is this happening when you print or when you scan? If when scaning you could have something on the scanner bed... If this is happening when you print, it could be the cartride is defective.

Test page and scanner


Hey satz, Take that test page, and put it into scanner, (Printed area will be on mirror side) then press scan button "Bottom left side of your printer". After stopping the fluctuation of light you will never face that problem. This error appears when you turn out the cartridge from your printer. sanjeev manglamenterprises@hotmail.com

Print Problem - vertical lines


If the problem only occurs when using the document feeder, the problem is not usually caused by the drum. When using the document feeder, try to notice where the scanner (the light assembly under your scan glass)stops just before the paper is being fed. Some multifunction machines have a small piece of glass that is separate from the large scan glass and the scanner assembly stays parked underneith it as the original is being fed over it. Most likely there is something on the glass where the scanner parks as originals are being fed thru the feeder. When putting your original on the large scan glass to copy, the mark on the glass will only show as a spot, but will show as a vertical line thru the whole copy when using the feeder.
