BLACK MARK ON THE COPIES OR SCANNED IMAGE


Clean the slit glass under the document feeder. Lift the feeder and find the thin piece of glass on either the left or right side and give it a good cleaning - you marks will likely go away.

Sharp IR 2016 platine glass dirty


The cover plate is above the glass white surface of the scanner. If this is the same dirty stains will come out on copies.
The glass must be clean.
By feeding the original documents through the ADF, the scanner lamp is no longer the path to scan, the ADF is responsible for passing the original document over the scanner, while it remains still placed on the side under a thin glass is to a large glass side. This also must be clean, otherwise you will be black lines on each point or spot on the glass.
Good luck ...

Why is there still a line showing through middle of pages when scanning/printing via top document tray of toshiba e stuido 351c? I know who to clean glass area but not top tray.


Does this line appear when you try to print to the machine? Or when you make copies on the scan bed? If so, then you most likely have a mark on the drum unit. If not, then the **** glass that the document feeder uses is located to the left of the large glass surface, attempt to clean that and ensure that no mark or scuff marks are on the **** glass.

I want to clean the underside scanning glass of the HP C4180 scanner/printer because when I scann, the top is clean, but the scaned pictures look like they have little specks of dust all over the scanned...


It takes several steps to remove the glass carrier for cleaning, but it's not really difficult. You'll need a T10 Torx screwdriver, eyeglasses cleaner or similar, and a lint-free microfiber cloth.

1) Remove usb and power cables. Flip the front covers open (revealing the cartridge-insertion area). Remove 2 screws from the right-side panel, and remove that panel.

2) Open the photo-paper holder on the left side, depress plastic tabs on its top and bottom so it can swing out 90 degrees, and remove it.

3) Remove 2 screws from the left-side panel, and remove the panel. This exposes the gears of the paper-handling mechanism; take care not to move the gears. Disconnect the three ribbon cables connected the bottom circuit board.

4) Flip up the LCD, exposing a screw. (Note that this one is shorter than all of the others.) Remove the screw. Lift the scanner lid and remove two screws just behind the rear of the glass. Close the cover. Lift the rear of the glass carrier, then slide it back slightly to remove it. Take care not to move the scanner bar that remains in the main body of the machine.

5) Keeping the lid shut, flip the glass carrier over over. Spray cleaner on the glass and wipe; repeat as needed. I use a bright light at a low angle to check for particles on the glass.

To reassemble, just reverse the steps. Finish by cleaning the top of the glass.

My Dell 926 all in one printer has started putting a red line through all the photos I try to scan. What is causing this and how can I fix it?


it could idicate a weak laser. try cleaning the glass with a soft cloth which also sometimes begins to give a kind of coloured look which it gets older. if none works trying moving the picture form position to position across the glass to see if it does give the same problem.
good luck and let me know of the outcome

The scanner is reporting an E2 error code when it draws a document in. Any ideas? Re-cycling the power clears error but comes back when I scan. thankyou in advance


Hi,

This error message means ADF front side scanning optical alarm (lower optical unit ADF) which indicates ADF (front) lamp intensity check. Please follow the steps provided below:

1. Is the upper glass (white sheet guide)of the reading section dirty?

Open the ADF, and clean the sheet guide (white part) and the glass.
# When operating the scanner, the ADF’s inside glass becomes very hot. Take serious caution as the heat can cause burns. Before you clean the inside of the scanner, turn off its power and unplug the AC adapter from the outlet and wait (at least three minutes) until it gets cold.Be careful not to pinch your fingers when the ADF cover is being closed.
Note: Cleaning should be done approximately every 10,000 sheets scanned, though it may vary depending on types of
documents scanned. More frequent cleaning is necessary when the following types of documents are scanned:
- Smooth surface document such as coated paper
- Documents printed on almost entire surface
- Documents processed with chemical materials such as carbonless paper
- Paper with a high calcium content
- Pages with pencil lead
- Document where toner is not fused sufficiently.

If the above does not help, then the issue is caused by any of the followings for which you may have to contact the Fujitsu Expert/Engineer.

1. Lower Optical unit ADF may be dirty.
2. Lower lamp may not be functioning properly.
3. The connecting cables might be damaged.
4. The connectors are not connected properly.

Hope the above information is helpful.

Regards,

I have a Xerox copier model XD105f. When the unit is first turned on or waken up the green scan light bar (I do not know the correct name) starts it's re-indexing mode the gets stuck repeating a 1/4"...


I have seen this occur if the reference strip (white strip underneath the registration edge on underside of glass) is dirty. Clean the underside of the entire platen with glass cleaner sprayed onto a cloth and wipe clean with cloth dampened with water. While you are in there, wipe mirrors with dust-free cloth. Take care to move carriage CAREFULLY as you can jump the cables off of the pulleys.

Line in copies that go thru feeder


Hi,

Over time the automatic document feeder (ADF) will get dirty, occasionally causing vertical black streaks or lines in scans and copies .

Manual cleaning of the ADF might be necessary. Follow the procedure below to manually clean the ADF .

You will need the following materials:
  • Soft lint-free cloths
  • Glass cleaner
if you look carefully on the left side of ADF ( top feeder ) there is an assembly which u can lift , there wud be a set of rollers if u lift that part there would be a glass strip . u are suppose to clean that strip .
While holding up the inside of the ADF, clean the glass in the location of the vertical streak with one of the cotton swabs. Try cleaning the glass first with a dry cotton swab. If that does not correct the problem, then moisten the swab with glass cleaner .
If the vertical lines or streaks still appear, go through the above cleaning process again, this time cleaning the entire surface of the ADF scanner glass.
and after this try the following steps as well .
CAUTION: Use only glass cleaner. Avoid abrasives, acetone, benzene, and carbon tetrachloride, all of which can damage the scanner glass.
