Put paper in the manual feed tray(tray 1).
When the paper gets about 1/2 way into the printer, open the top cover.
Pull out the toner. Look down at the paper in the printer.
Do you see a thick dark line? Replace the toner.
No thick dark line, check the fuser for damage.
You can try to clean the scanner light, but the light does not cast a straight one directional beam. It is more like a flood light, if one spot is blocked it will still cast light on that spot of the paper. Try checking the print cartridge. Normally if it is an inkjet copier, it will leave a line in one spot if there is a defect in the cartridge or if it is running low on ink. I woul try another cartridge first, then we can go from there.
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.
You are getting black lines in green color,and apperence of parallel light and dark lines because your colour catridge is almost empty.So solution is replace the catridge and take a printout. There is no proplem with a printer. i think it solves your problem.
Notice where the metal retainer beneath the glass cuts off the view of your document you wish to copy and make allowances on your copy. Most printers disallow some portion of the edges of any document for handling the transport of the document through the feeder, or in the cases of contact copiers, a portion of the sheet as you have experienced, so that the edges need not be so carefully adjusted to avoid the dark line in edge copied formats.
Format all documents so that you do not need to copy the portion excluded.
Sometimes this can be accomplished by reducing the size of the document.
Streaks in direction of paper travel
There are dark lines running along
the page in the direction of paper
travel from the leading edge to the
trailing edge (B-size print shown).
The printer displays no error code.
Note A-size prints are processed
through the printer with the short
edge of the print parallel to the
direction of the paper path --
making horizontal print artifacts
parallel to the shot edge of the
B-size prints are processed
through the printer with the long
edge of the print parallel to the
paper path -- making horizontal
artifacts parallel to the long axis
of the print.
1. Check the end of life for each of
the consumables by printing the
supplies usage page. From the front panel’s Printable Pages Menu, select
Print Supplies Page.
2. Run the solid fill test pages; From the front panel’s Printable Pages Menu,
select Service Pages, then select Print Solid Fill Pages. If the missing bands
only occur in a single primary color, replace the print cartridge of the affected
3. Swap print cartridges and run another test print.
Note Under some circumstances, streaking may occur in the margin of
SRA3-size paper. This is due to the edges of the paper extending
beyond the end of the imaging components. print-quality in the
margins of SRA3 paper is not guaranteed.
4. Inspect the Accumulator Belt cleaner; replace the cleaner, if necessary.
5. Run the Remove Print Smears routine. From the front panel’s Support Menu,
select Improve Print-Quality?, then select Remove Print Smears.
6. Replace the Developer Housing Assembly (RRP 27, on page 7-171).
7. Remove the print cartridge and (with a flashlight) check for debris along the
edge of the developer housing.
Leading Edge hope that this will help you.
As far as copying goes, it could be lines on the scanner glass. You might want to check that out.
Do you have any way of checking the condition of the drum on the cartridge to see if there are any lines on it. Find the drum cover protector by removing the drum cartridge straight up, lift the drum protective cover and see if there are any lines on the green surface. Try to keep it out of direct light as much as possible. Make sure you lift it straight up so no toner or developer spills out.
I've seen a few cases where the cleaning blade on the drum is defective. Usually you can return them and get a replacement at no charge.
