Printer is printing with horizontal blank lines


you did not indicate machine or how you are printing.

1- printing from glass or doc feeder?
did you check the small scanning glass on left side?
usually if there is a dot (pen dot or similar) it will come out as a line on docs, this is because the paper is moving while scanning, so it now sees the dot a s a line. Line up the paper w the glass you should see where the problem is comong from.

Horizontal print gaps on ml184+


Hello,

The most common cause of missing sections in the letters is a bad print head. These types of printers (Dot Matrix) create the print with the print head which has a line of small pins called hammers that are activated by an electromagnet. Each pin has its own hammer. If the electromagnet fails or you have something jamming the hammer then it will not move to strike the ribbon and make the image or letter. You can get a replacement print head online for about $15.00, the part number is 50063802. Here is a picture of what the print head looks like. :

When I copy there are black lines across the page. I changed out the cartridge for a new one, but it still makes the lines.


Lift the copy bed cover and locate the **** glass (it is about 1" wide and sits on the left of the large glass)

Use a microfiber cloth, and a bit of water, and remove the debris from this **** glass. Make sure it is clean, then clean the white bar on the underside of the top cover (It will sit on that **** glass)
take a blank piece of paper and copy it through the feeder, if you have lines on the page that prints, you need to look harder for a spec on that glass. a small dot will create a line on any document fed through the feeder. A dot on the large glass will print only the dot as the paper is not moving over it.

When scanning dots show up in a vertical pattern


Printer DPI and PPI Ratings, General Dots per inch stands for the maximum number of tiny spots of ink that the printer can place in a straight line where the spots are theoretically small enough (i.e. ignoring spreading or smearing effects of ink on paper) that if placed in every other such dot position leaving white space between them, the spots can be individually distinguished. Pixels per inch stands for the maximum number of unique positions in a straight line that the printer can place an ink spot under control from the outside world, namely from a computer connected to the printer. Lines per inch stands for how close thin parallel lines can be printed and still be distinguished in the finished printout. The spaces between the lines count as "lines". Pixels per inch and dots per inch originally referred to the same thing. The printer mechanism was under the direct control of the computer and was physically positioned and placed dots as directed by the computer. Back then, most printer mechanisms were limited to placing dots only in positions suggested by a grid of dots X per inch horizontally and Y per inch vertically, for example 100x100 dpi Nowadays, many printers put dots "wherever they want" as opposed to in positions suggestive of a horizontal/vertical grid. Still there is a minimum dot size and a minimum dot spacing. A picture file (image file) represents pixels in a uniform horizontal/vertical grid pattern. And the printer needs to make a finished picture of the size, say 5x7 inches, that the user chose regardless of the number of pixels in the picture file. To simplify the process of relating the pixel count in the picture file to the possibly non-uniformly spaced dots on the paper, the printer or its supporting software may generate a temporary intermediate picture file with a set number of pixels per inch. The printer may have, internally, several choices of ratio of pixels to dots and the published rating can be the largest ratio except that the published rating may not exceed the dpi rating. Therefore there might be three "per inch" values involved at a given time, the pixels of the original picture file, the pixels per inch that the printer works with, and the dots per inch of the printer mechanism. Pixels per inch is usually not mentioned with printers. All printers come with their own software (including parts called drivers) to install on your computer. Usually the software does not let you exercise control over individual dots using your picture file. Rather the printer takes your picture file or data file and uses its own built in logic to lay down the dots and create the printed output. We are led to believe that a printer's ppi is usually a fraction such as a half or a third of its dpi rating. When a temporary picture file is created, there are at least two levels of software in use. High level software (which may run in your computer) takes your picture file and creates the temporary file. Low level software runs in the printer, takes the temporary file and controls the dot size and dot placement on the paper. Sometimes a printer is advertised using a phrase such as "300 dpi 1200 dpi quality". This means that the printer has some way of making dark edges on a light background appear smoother than the first number would otherwise suggest. A printer with 300 dpi 1200 dpi quality definitely cannot resolve alternating dark and light pixels less than 1/300'th inch each. But curved and diagonal lines and color boundaries should not have jagged edges suggesting individual dots rigidly positioned on a grid with a 1/300'th inch pitch.

Poor Print Quality


the print head has a series of pins that shoot back and forth striking the ribbon and placing a dot on the page, a series of dots create a letter etc. one pin is not working correctly. it could be the head but try re-instal drivers to eliminate that as a cause. if the line persists then i'm afraid it may well be the head to be replaced. good luck
