  • My iMac doesn't work that in safe mode, normal mode the screen layout is really weird. Help, please! :)

    Hi guys,.

    Since yesterday my iMac 27 inches of the end 2009 has acted weird. Text was not good more visible and popupscreen were empty, white or black. (do not know why they are uploaded in reverse)

    Then I tried a clean install. Screen was working again fine. Then formatted my drive and installed the new OSX.

    Download went fine, but when installing the pop-up screens were not visible.

    After a few random reboots on my side, it worked again.  Thus, installation...

    But... Now, I always have the same question. In safe mode, everything works fine, but in normal mode, the screen is *. Pop - up screens are blank/black or white, the numbers are mixed, etc. What it can be.

    I already installed it on an external HARD disk, reset the SMC and the PRAM, Test hardware (message only 1 failure: 4sns/1/40000000: TH00 - 9,000.) "But I think it's because I installed my SSD later, that's why I need to use a program like HDD control to control the fan).

  • vertical white line on the printed document

    A vertical white line appears on all printouts.  The text print normally on the white line on color documents. on black and white documents, white interrupted the printed text, how this can be fixed?

    I use a portable printer Officejet 8500 a Premium with Windows 7 Ultimate.  However, the problem has resolved spontaneously.  I cleaned and aligned several times and my assistant copy a number of documents on the printer and then printing my document there was no evidence of the vertical white line.  Thank you very much for your help.

  • HP Officejet 8040: White line, do not print, vertically when printing from HP Officejet 8040 all in one.

    The white line appears when I print. This has nothing to do with the scan or copy.

    It's about everything that I print and sound always vertical and in the same place.  The Interior of the 8040 seems pretty locked. Not much to go and see what it could be at this place in the printer. I ran the vacuum cleaner at least 5 times and the alignment of 3 times. Help, please.

    The problem you see may be caused by a spot on the MICR band.  You can clean the Strip as shown in the here document coding.  Be aware that the coding Strip is fragile and there are fine lines, printed on the Strip that are essential to the proper functioning of the printer.  Be very gently when cleaning of the band, if you're too vigirous band (and printer) will be damaged.

  • Printer AIO 922, Solution of white lines

    I have a printer Dell AIO 922 a 3 or 4 years. It has been a very solid performer like a use inkjet housekeeping and I wouldn't hesitate to buy another Dell printer based on this one.

    Recently, it started showing the white lines, or more precisely, the horizontal white gaps. As the snapshot on the right. I searched everywhere but not found a solution. Available notice usually includes nozzles cleaning or using the alignment. A proposed post to wipe coding transparent plastic strip. These things did not help. Being an engineer and a professional problem solver, I decided to understand it. I hope that it is beneficial for someone else, as I often took advantage of other messages.

    First note is that it is a paper feeding issue, nozzles ink jet not blocked because there is no ink "missing." If you close the gap, the letters would be properly trained. The gap that has happened on each 37 mm (1.4 inches) to the bottom of the page. I was thinking one of the plastic gears in the drive of the paper feed system is broken or clogged with impurities, etc. With that, I decided to open it up and look at the bowels of the printer. I realize that many people prefer to go out and buy a new printer that do this, but it's for the rest of us. Because it is unusable, and there is no alternative available, I had little to lose.

    I unplugged all the cables power and carefully removed the top of the hinge scanner, being careful not to damage the cables sheet fragile 3 or 4. So I removed the 3 screws in the lid of the lower unit (printing). Carefully open and removed the lid of the snap-in using a knife and a flat blade. ATTENTION: you may need a second set of hands very patient to avoid damaging the hinges and cables that connect the top scanner at the base of the Ribbon. All cables can be removed gently from their connectors, but it's a little tricky. Tip: tape the scanner to scanner bed cover and the support arm to scan at the base of the scanner so that they are not flop around as you work on this.

    Now, you are looking in the Open box. On the right side of the friction of the main axis of power (the tree is approximately 1/2 "in diameter and has a rough surface to pull the paper into the printer) is a thin, transparent plastic disc. There are thin black lines around its outside edge that pass through an opening with an optical sensor that the shaft turns, driven by the engine. This provides a precise location feedback paper power control.  The disc is difficult to achieve, so I took a Q-Tip with alcohol to friction and wiped two sides that I shot it through the white plastic gear. Make sure you do not damage it. I repeated until the Q-Tip has come back clean. It looks like a small jet of ink mist gets type everywhere inside the printer, judging by other surfaces. So, after a few years of use, he had finally started do the misread encoder and cause the power issue of paper resulting. I have put together and he has beautifully reprinted.

    In this printer and I suspect in many other inkjet printers, there are 2 sets of engine controls, mechanisms and encoders. One for the race the printhead horizontally and one for paper feeding. In my research, I have never seen this mentioned. I've seen many, many messages asking for solutions to the "horizontal"white lines "-much of which doesn't seem to find solutions.  So, here's my karmic contribution to those who are willing to delve a bit inside the box. Good luck.

    Awesome! Thanks a lot for posting this solution. I just followed your procedure for my Dell 922 AIO printer works again.

    Hello sz6,.

    Looks like you may need to clean the lid of the scanner printer and it's other components.

    See this troubleshooting article for step by step instructions.

    Vertical stripes, lines or streaks on Copies, faxes or scan

    This article can also help to solve your problem.

    Received faxes are empty or have vertical lines

    Articles specifically mention the vertical lines, but given that printing works very well and it has only the faxes or scans I think that information is still valid.

    It is a problem that is known at this stage and is still under investigation by the folks at Adobe.  As they work through it, move your projects to the software rendering and move the SOUL to software exports.  It may take longer to work through things, but you avoid the strange lines.

  • White lines around png when exporting to PDF

    I'm having the problem that the imported images frequently have white around the outside of the image bars when the document is exported to PDF format. Looking at the two images currently affected, I noticed that they are two PNG images. I have fixed the image that was just rectangular turning them just in a JPEG file that I did not require the use of transparency, but the second object is another question, and I require the use of png transparency. These lines are not normally present when in indesign.

    Line is noticeable only in one place where a black rectangle together black background (only the upper part of the rectangle is visible on black as one side is covered and the other side is outside the crop area) so I don't know if it's the only spot, it happens.

    The line isn't even a straight white line!

    I had this problem before with lines that appear around objects that should not be there, as well as objects are not like they do in inDesign, any advice to solve this?

    I don't think you should use PNG for the files that will be printed. You would probably get better results if you saved your png as TIFF and replaced in the layout.

    In any case, it could be a consequence of the piquant effect and just one thing on the screen only when it prints very well.

    In Acrobat disable "Smooth line art" and "Smooth images" in the Page display preferences and the white lines could disappear.

  • Unexplained white lines in formats EPS and HAVE

    Thanks for taking a peek. I'm at my limit with this one.

    I have a book in InDesign CS4 with overall imported EPS pictures. The EPS files created with Illustrator CS1/CS4 (we have updated recently - ago, big jump!). When you test the exported PDF book we noticed that several images have what seems to be random white lines framing the areas of the work. I searched through the knowledge base on the seam, sought in Illustrator/InDesign forums on 'white lines' and various other key words, but so far I have not found a honest solution. I tested these corrections starting with settings display "Line Art/Smooth Image" PDF, InDesign "Aplatissements predefined transparencies Transarency" smooth, all the way back to the work of the Illustrator files.

    I must emphasize that these lines are only visible on the screen after a series of expansions in Acrobat or InDesign. The lines are not visible on the screen in the EPS formats / HAVE, however, when you print directly from Illustrator, they find themselves on the hard copy. There is at least a starting point?

    In one of the most obvious examples, we noticed framing around objects with drop shadow effects. The background of this image is a gradient. The foreground object has a shadow effect. We tested the removal of the shadow effect and the lines disappear. We then reapplied the shadow but removed the gradient of the background. Again, the lines are left. All this is fine I guess, if we need to go through each drawing and eliminate any shadow scope and/or degraded (rather annoying though and disappointing that some effects may be inevitable to represent a series of illustrations). But honestly, is it normal that these two effects of situations of conflict in this way? The biggest problem is that there are designs with these ghosts lines that have no background gradient shadow or drop. I have no idea where to solve this!

    From what I read and what I've seen with tests, there is a problem of transparency, supported by our experiences with shadows - possibly in the original format of EPS designs are created in. ' save under... ". ». I does not solve it. Backup to a flattened. TIFF or even. JPG is really not an option.

    With the help of shadows with gradients is a no-no? Maybe something in the transition from CS1 to CS4? I'm a clueless fool who just needs to stick with Photoshop? Laughing out loud. I do not know!! Someone please enlighten us on this one. I try to understand these things on my own, but Illustrator is my weaker demand. In any case, all tips are very much appreciated.

    Thank you in advance.

    -Christmas.

    I use Illustrator CS3 and had the same problem.  I finally got the white lines if go by saving my file .ai, flattening of the work (go to the layers palette, the pitcher, then "Flatten the work"), print to a .pdf file (or I guess you could save as), and then close the .ai file without saving (because I didn't want the flattened .ai file).

    It worked!  Woohoo!

    It is a good idea and makes me think that my reference to flattening is misleading. Flattening in the layers panel work can definitely have an effect on transparency, but this isn't a flattening of transparency in the strict sense of the term. Julie mentions printing in PDF format, or save as PDF. These are two totally different things. In the case of printing to PDF, the output is post script, which does not support transparency. The PostScript is converted to PDF. So it could be transparency in the document of the monolayer, but transparency has been flattened at the printing stage.

    This method can be effective, but only if the PDF output does not need to be placed in another application. In any case, Julie was correct does not back up after flattening the layers.

    I spent hours trying to solve this problem.  I did as stated in this thread, and passed under the eps to AI file, but would really like to know why this is happening with this particular eps file.

    Maybe we can find a solution to this problem.

    Kristeejo you should display your illustrations drawn mode and see if you have pictures divided into sections. If Yes, then this is perhaps the result of some with object: flatten transparency. It's very embarrassing when someone does this. Sometimes, you can select the pieces of the image (see the links Panel, they are all integrated links), then use object: pixelation. Do not do this to vector elements. After rasterization is completed, the pieces become an entire image, and I hope that the seam lines will disappear.

    The other possibility - and the solution because it is much easier - is that someone has placed a Photoshop EPS, and it is interacting with transparency. You can re - register the Photoshop EPS as a native file to Photoshop and re - link. I've seen it eliminate the thin white lines in output.

  • White lines in the table

    I am new to the use of Dreamweaver and I was trying to make a website composed of images. I created the template on Photosho CS2 and then I slice them and I'm doing my site in Dreamweaver using tables.

    I started doing 1 line and column and then I continued on by splitting of cells and to make my site but it does not come out right. I have these small white lines between rows and columns. I tried to press (ranging from all rows and all columns), but still nothing changes. Here is a screenshot of what my site looks like:

    Can someone please tell me what to do to get rid of those white lines. Also, I checked the code and I see no tag so it cannot be that.

    Problem is some parts are normal as mentioned Osgood and parts are not. The only thing I can think is nested tables which I don't know is a good idea.
