Double printing can occur for several possible reasons including an improperly seated ink tank, a misaligned print head, and a dirty encoder stip.
removing the cartridges, unplugging for 30 secs, replacing cartridge. uninstalling/reinstalling the print driver. realigning. making a copy works fine.
Ghost prints happen when the drum or fuser unit within your printer become faulty. Because a fault with this element won`t heat the particles of the toner to a high enough temperature, the marks being made on the paper are much lighter in colour and appear more faded than typical documents.
To prevent ghosting, it is crucial to be efficient with the speed of the print head and the material. This means slowing down the print head in time and gradually, and printing less material before changing direction. For example, before a sharp turn.
Description. im2double takes an image as input, and returns an image of class double . If the input image is of class double , the output image is identical to it. If the input image is not double , im2double returns the equivalent image of class double , rescaling or offsetting the data as necessary.
Ghost printing happens when an image or text is repeated more than once on a printed page. This is often caused by an issue with your drum unit, which is the electrically charged cylinder that transfers toner powder on to the paper.
Ghost imaging, often called cloning, is a software-driven data backup process that copies the contents of a computer hard disk in a single compressed file or set of files, referred to as an image.
When you enable Ghost Mode, your location won`t be visible to anyone else on the Map! You can turn Ghost Mode on and off, or set a timer if you only want to be on the down low for a little while.
transitive verb. : to produce two images from two negatives in a fixed position on (a photoengraving plate)
The overlapping occurs when a text field is not wide enough for the text it contains, causing the text to automatically scroll below the first word. The second word is invisible on the electronic copy, but is visible when printed. To remedy this, you can expand the text field by dragging the handles on the field.
The double thresholding idea is to use the output from the higher threshold to select all the touching regions in the output from the lower threshold. Morphological reconstruction can do exactly that. The Image Processing Toolbox function to use is imreconstruct.
To compare two images, we use the Mean Square Error (MSE) of the pixel values of the two images. Similar images will have less mean square error value. Using this method, we can compare two images having the same height, width and number of channels.
Ink and toner problems can include streaking and fading (which usually indicates a dirty print head) or toner in a laser printer that is running low. For inkjet printers, the print head may need a good cleaning. The printer utility app that came with your printer will include a cleaning option.
Full-duplex data transmission means that data can be transmitted in both directions on a signal carrier at the same time. For example, on a local area network with a technology that has full-duplex transmission, one workstation can be sending data on the line while another workstation is receiving data.
The Stacked-CNN method can detect most shadow pixels in the dataset, but it also causes pixels in non-shaded areas to be insufficiently recalled. Some non-shaded pixels are wrongly classified as shadow pixels, resulting in blurred shadow detection images, which is consistent with the results of qualitative analysis.
If your refresh rate or resolution is too low or too high for your monitor, it can cause flickering or ghosting. To fix this, you need to adjust your refresh rate and resolution to match your monitor`s specifications and capabilities.
Relationship experts and psychologists agree that people who ghost are avoiding an uncomfortable situation. This evasion, while perceived as a lack of regard, is often because they feel it`s the best way to handle their own distress or inability to clearly communicate.
Shadow printing is a printing technique that creates a lighter shade of the text off centered to make the text appear to have a shadow beneath it.
A ghost image is a commonly observed artifact in an orthopantomogram whereby a dense, often metallic object is located between the source of x-ray and the focal center, resulting in a duplicate `ghost` image at the contralateral aspect of the image.

By default, Ghost stores any images uploaded to Ghost Admin locally to its filesystem, and delivers them via the same Ghost front-end service which delivers Ghost themes.

In order to ghost someone, don`t reach out to them at all. That`s the definition of ghosting. If they text, call, or message you, don`t respond. Eventually, they`ll get the hint that you don`t want to talk anymore, and they`ll stop reaching out.
Double exposure results when the receptor is exposed twice, and two images appear superimposed onto each other. This error results in two errors; one receptor that was double-exposed and another that was not exposed at all. It is extremely important to avoid this error because it exposes the patient to radiation twice.
The best way to prevent or reduce ghosting is to use a lens with multi-coating, which is a type of coating that reduces the reflection and transmission of light within your lens elements. A multi-coated lens can also improve the contrast, clarity, and color of your image.

Laserjet 4250 print quality issue (see image)
ANSWER : It looks like a fuser problem. One way to prove it is with the half-stop test. Put a sheet in the drop down manual feed tray. Send a print job and watch the paper. When the end of it is about to enter the printer, open the lid and take out the toner cartridge. Look at the printed image. If it looks OK, then it is a fuser problem. If not, then it is a toner cartridge issue since it hasn’t gone through the fuser.

Samsung CLP-300 Image Ghosting
ANSWER : Hi there – did you resolve your issue? It exactly mirrors the issue with my Samsung CLP-310. Each print carries across to the subsequent print as a ghost/smeared image and I diagnosis has revealed the transfer belt (ITB) has smeared toner remaining post each print. I was therefore considering replacing the Transfer Belt, but fear it is not the issue as you found. Whatever should be removing the toner from the Transfer Belt post print, is not, and then I get smeared ghosting on subsequent prints of the last print. The only mitigation is to print 5 blank pages post print, then the ghosting/smearing reduces to nearly zero (proving that the toner is being removed partially at least)…. Any help gratefully received.

Print Quality Issue (Streaks and Ghosting)
ANSWER : Streaks are mostly caused by internal drum wiper blades that clean left over toner off the drum to prepare it for a new image. Ghosting is caused by a leftover image on the drum. The 6 inches that you mention would be the circumference of the part that is causing it. Fusers will never cause either problem.

ANSWER : You don’t have to replace it until it wears enough to affect the print quality. You’ll get spots or stripes. Here you go on a free reset. If you read the thread, someone says the procedure also works on your model. http://www.fixyourownprinter.com/posts/33634
