Horizontal streaks HP LaserJet 3200m scans
How do I get rid of horizontal streaks HP LaserJet 3200m
copies and scans? Whether I copy or scan, I get horizontal streaks like this: ______________________________________ |xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx| |xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx| |xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx| |xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx| |xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx| |-------------------------------------| |xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx| |xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx| |-------------------------------------| |xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx| |xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx| |xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx| |xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx| |xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx| |xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx| |-------------------------------------| |xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx| |xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx| |xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx| |xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx| |xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx| |-------------------------------------| |xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx| |xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx| ______________________________________ What is the cause and solution for these horizontal streaks? |

Measure the distance between the streaks. Using the downloadable service manual, or the "Print Quality" help page, you can isolate which element is contributing to these streaks due to how far apart they are (each of the rotating elements are a different diameter, so their tell marks are different spacings apart.)

True, but also try a new toner cartridge, just to make sure, and that is the easiest rotating bit to replace. But there is no toner in the case of scanning a photo. 1. I put the photo in the scanner slot (the HP LaserJet 3200m is not a flatbed) 2. I bring up IrfanView on Windows & select IrfanView: File Acquire/Batch Scanning 3. That scans the photo into the computer but the result is horizontal streaks (perpendicular to the direction of the paper flow). The glass plate inside is about 9 or 10 inches wide and 3/4 inch tall and I cleaned it before asking you what the problem was. I don't see anything else inside that "sees" the photo other than that paper-width wide strip of 3/4-inch wide glass. The conundrum is that the streaks are in the opposite direction as anything that touches the photo (the rollers roll in the vertical direction but the streaks are in the horizontal direction). That enigma should give me a clue as to what the cause is, but I can't think of anything that goes horizontally. This is what the HP LaserJet 3200m looks like https://www.tradebit.com/usr/manuals...Mservman01.jpg The manual is 10 dollars https://www.tradebit.com/filedetail....service-repair |

In fact, it's pretty clean. Here is a scan of a photo that was put in the slot long-side horizontal. So the scan was vertical. http://i.cubeupload.com/dmSy3Y.jpg Notice that the scan was from the top to the bottom of this picture (from head to toe) but the "scratch" lines are from side to side (which is not the direction that the paper moved). There isn't any moving object side to side, is there? (The horizontal scratches are not in the original photo!) |

Do you get the same streak when you use it as a printer instead of a copier? If so it is a print engine problem. If not it is a scan engine problem. Almost 100% of scanning problems that produce a line the length of the scanned document are caused by a little spot of dirt on the scanning element - it looks like a class bar across the paper path - check for a spec of dirt - possibly white-out on the class. Tou might not be able to see it but you should be able to feel it - scratch it off and the line will dissappear. |

You'll be amazed at what can blow out of insides. Also, turn it upside down to remove staples and paper clips. Here is a scan of a photo that was put in the slot long-side horizontal. So the scan was vertical. http://i.cubeupload.com/dmSy3Y.jpg I think that means that your landscape photo moved through the mechanism lengthwise, or from left to right. Is that correct? I'm not sure because the landscape photo shows white lines perpendicular to the stylized lines shown in your original posting. Perhaps it might be better if you abandon the landscape scan and switch to a more consistent portrait scan? Extra credit for annotating the JPG to highlight the problem. Notice that the scan was from the top to the bottom of this picture (from head to toe) but the "scratch" lines are from side to side (which is not the direction that the paper moved). There isn't any moving object side to side, is there? (The horizontal scratches are not in the original photo!) I thought it was the horizontal white scratches that you wanted to eliminated. I don't see any scratches perpendicular to the white scratches. However, if it is the white scratches that are the problem, the answer is obvious. You have some dirt, white out, toner, or label glue stuck to the document scanner window. In the service manual: Go thee unto Pg 226. That's the document scanner assembly on the front lid (behind the keyboard). The should be a narrow glass window in the document scanner somewhere. It's usually about 1/4" x 8.5" and runs along the width of the page. I can't find it in the various exploded views, but it has to be there. My guess(tm) is that it's covered with speckles of dirt, crud, dust, white-out, glue, etc. Clean it and the white streaks should disappear on the scans. Just follow the paper path during scanning. It should be somewhere along the path. Another possible cause is that you have light leaking into the document scanner assembly causing the white streaks. I can't tell from here where it might be leaking in. Try a scan with the room lights turned off, or with a cardboard box over the 3200m, and see if the streaks disappear. Good luck. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

So the rollers would be parallel to the 11" side. I've read all your posts and they all seem to say that, except for your conclusion that the rollers are vertical. I don't like either horiz or vert, I don't know what they mean, but I do like parallel or perpendicult to 11" side. Does your owners manual have a troubleshooting section? |

I believe I am the only poster who gave instructions based on determining first if it is a printer or scanner issue. NOWHERE that I can find has the OP clarified whether the lines show up is simple prints. All I have found was in "copies" and "scans" A 3200 is not a flatbed - so if there are lines in the scan, they will be from something contaminating the scan head and will run the "length" of the paper - in the direction of motion through the scanner. There is no other scanner failure mode that will produce any other pattern of lines. If it is a PRINT error, there can be several patterns - with different causes - and generally the same solution. If the lines are the "lenth" of the paper and present on prints as well as copies, there is a scratch in the drum - usually but not alwats preceded by "spots". If they are the width of the paper and evenly spaced by about the circumference of the drum, there is a defect line across the drum USUALLY this is not as crisp or clean or fine a line as the other possibilities. The solution to both PRINT issues is to replace the drum/cartridge. The solution tu the scanner problem is a carefull and thorough cleaning of the scanner element (unless someone has scratched it by running a staple through it) |

Yet, the streaks are horizontal (in the opposite direction in which the paper physically moves down through the scanner). A scratch on the toner cartridge drum would make a vertical mark, but the edges of the aperture can also make a horizontal defect on the drum; it might be something simple (a dust line, removable by lifting it off with a piece of sticky tape) or it might be a defect caused by overheating and fusing of the toner. |

Horizontal streaks HP LaserJet 3200m scans
I actually have one of these. Not a wonderhorse. Plagued by a third party software package and deliberate NO NETWORK policy. I have seen streaks and generally they are caused by foreign objects on the glass or other scanner parts.
However, it could be a sensor starting to go, memory failure, or even an issue with the driver. Is movement smooth with a repeating cadence during scan? Do you have a piece of paper from a previous paper jam floating around inside? Try some canned air. Also try scanning COLOR photographs at high resolution and see if the error stays in the same place. If it does look for optical problems from glass to scanner. Reinstall your drivers. Good luck! |
