All copies and scanner outputs result in a totally black image

You have no light output. The system places a charge, the image will remove charge (without image processing, the system leaves full charge ) (removes charge where no image is if negative processing)
EX: a copier has platen closed makes a copy because the cover has a white surface the light is reflected and removes charge from Drum. If you make a copy with platen open out put will appear black. Charge was not erased, toner is attracted to charged area.
Most systems use a small wire to place charge, depending on what development (pos or neg) with broken wire will also result in either a black or blank output. I would look for a broken charge wire.

Hello joe,hope you are well.Canon copiers have literally hundreds of "meters " that the device is constantly monitoring.Things like the number of 11x17 scans,reports printed,incoming faxes,outgoing faxes,prints at 600 dpi....etc.Its wild.The device is capable of displaying to the customer a total of six meters.The displayed meters may be customized for the customer by a technician as per the customers request or needs.Each meter is named by a number,for example "101".That particular meter indicates the total of how many sheets of paper(regardless of size) that have successfully exited the machine.102 meter indicates the total number of sheets that have been output using 8.5 X 11' as the basis.So a sheet of 11x17 paper would increment the 101 meter once,but the 102 meter would "click" twice.For billing purposes my company keeps an eye on the 102 meter to maximize profit,as it should be.Now how Canon determined the display of the other meters you see is a mystery.Again there is a meter named 958,which is the number of documents scanned to the MAILBOX. So, to completely answer your question: 108 is the total black and white copies made regardless of size.230 is just color and monocolor regardless of size.321 is{your gonna love this one}color prints on 11x17.322 is color prints on 8.5x11.So there ya' go! TMI city!!! Hope this helps.

IssueWhen you copy, fax, or scan an original, the resulting output contains vertical bands, lines, or streaks in one or more colors.When you print the original, the output is normal.

• Static interference
• Loose USB cable or power cord connection
• Fingerprints, smudges, lint, or dust on the scanner glass

Pls check your color Scan settings. Generally there will be some color difference between the original and scanned Image because, the original is 'reflected light' whereas, the scanned image is a 'source light' on the monitor. The monitor setting can also affect the color output. S. Mohan

First you should have installed the scanner in the computer using the cd comes with the scanner.

1. Confirm that the printer is powered on and press the <Open> button. (The paper output tray will open.)
   
   
   
   
2. Load paper in the auto sheet feeder or the cassette in the portrait orientation.
   
   
3. Lift the document cover and set a document on the platen glass.
   
   
   MEMO:
   
   - Regardless of the document size, set it in the landscape orientation.
   
   - Place the copying face down on the platen glass.
   
   - Align the document with the alignment mark (shown as the arrow) on the lower right corner of the platen glass.
   
   
   Note: The machine cannot scan the area approximately 3 mm from the front and right edges of the platen glass.
   
   
   
   
   < 1 > Alignment Mark
   
   
4. Close the document cover gently.
   
   
5. Confirm that the printer is in Copy mode. If the printer is not in Copy mode, press the <COPY> button to switch into Copy mode.
   
   
6. Check the copy settings, following the procedures below carefully.
   
   
   
   
   < 1 > Check the paper size and media type.
   
   
   < 2 > Use the up / down cursor button to specify the number of copies.
   
   
   < 3 > Use the right / left cursor button to adjust the intensity.
   
   
   Memo: Pressing the right cursor button increases the intensity. Pressing the left cursor button decreases the intensity.
   
   
7. Press the <Color> button for color copying, or the <Black> button for black & white copying. (The printer starts copying.)
   
   
   Note: To cancel copying, press the <Stop/Reset> button.
   

This has something to do the brightness chosen. In the manual mode, if you choose a dark output, the output will have tis area also; if you choose, lighter output, it will omit. In the auto scan mode, the scanner decides what is the best output.

Get you a HP scanner

A color scan will give real output as it is. If the background is grey, the output will also be grey. If you select 256 Color output, there may be small change in color, as compared to the original. If you select grey output, all colors will be converted to Grey. If these files are converted to PDF, it will be same, except in ODF format.

If you select B&W you can save the file in TIFF format. Unlike grey or color, each pixel can be either black or white only. To scan in black and white you must select right brightness. By doing os you can eliminate background (technically noise) and capture foreground(data)

i is problem with your scanner if you ablt to open it and just apply little bit servicecing for your scanner head rod or ypy can show it service peronnel.
