This is coming from the toner cartridge. Replacing the cartridge will fix this issue at leat 95% of the time. This problem is caused by a defect or damage to the drum in the toner cartridge. If you have a new spare then just swap them out. If you do not have a spare even an old empty cartridge can be installed to verify that the cartridge swap will resolve the problem.
Good Luck and Thank You for using Fixya.

X2250 won't print form pc


A technique to improve print quality is to try and clean the cartridge nozzles. You may clean the cartridge by following the steps given below:
1. Go to the "Lexmark solution center." This can be done by clicking on "Start," go to "Programs" and Lexmark printer group. Click on the "Lexmark Solution center." Next click on the "Maintenance" Tab.
2. Select "Clean and Fix Horizontal streaks." Click on "Print". This will produce a printed page.
The colors that you should see here are black, yellow, magenta (a reddish purple) and cyan (a dark sky blue). You should notice the diagonal lines above and below the solid horizontal lines. These diagonal lines should be solid from left to right with no gaps.
If there are gaps in the lines or the print diminishes across the page, you should run the "Clean Print Nozzle" page a couple more times to try and clear it up. If you still have gaps at the top and bottom, you should "wick" the cartridges by following the steps given below:
1. Please open the "Solution center" again and go to the "Maintenance" Tab.
2. Select "Install color/black cartridge" and remove the cartridge or cartridges from the printer.
3. Get a damp paper towel.
4. Set the ink cartridge right side up on the damp paper towel so that the ink nozzles are against the towel and hold the cartridge in this position for about 15 seconds.
5. Now wipe the print head (on the bottom where the ink comes out) across in one direction only (left to right) until it looks clean.
6. Next dab the cartridge on the towel to make sure that the ink is flowing.
7. Snap the cartridges back into the printer.
8. On your computer, select "Old Cartridge install."
9. Repeat the "Clean Nozzle Page" one more time. If this fails to address the problem the entire procedure may need repeating.

Good Luck!!!!

How i adjust horizontal size and vertical size


To answer your concern, all you have to do is to change the setting of your aspect ratio on your TV.

Here is my suggested way to procede:


1. Apply 1080i signal, which should produce an oversized HD image on ColorStream1or 2.
2. Select an HD channel that is broadcasting standard 4:3 image, not wide screen.
3. Switch to the Service Mode ( Please refer to the above links). In the Service mode, press channel up/down to find the Adjustment parameters needed for the following steps.

4. Adjust HIT with volume up/down control for the image height to 22.5 inches.

6. Adjust WID for image width of 30 inches, (22.5*4/3)
7. Adjust HPOS to center the image.
8. Adjust PARA and TRAP to minimize geometric distortion.
9. Switch into Convergence mode and Adjust VLIN to get equally spaced horizontal grid lines.
10. Measure the length of the central grid lines and note the number of horizontal and vertical grid lines. This information is used to create an overlay grid.
11. Create the overlay grid on 40x25 x0.003 inch clear Acetate sheet, which you can get at the Art Supply store for under $2. Draw the grid with a fine line erasable pen. Draw vertical and horizontal lines through the center of the sheet so that the lengths are the same as the central grid lines. Now draw the grid so that it has the same number of lines as the convergence grid but are equally spaced, with the outer ones at the ends of the central lines.
12. Cut off about 1/4 inch from the right side of the sheet so that the sheet can lay flat against the screen, which is slightly less than 40 inches.
13. Put a reference mark on the TV frame 2.5 inches down from the upper left side of the screen.
14. Place the overlay on the screen so that the upper edge lines up with the reference mark. The overlay sticks by electrostatic attraction.
15. Use convergence controls to remove grid distortion and converge grid colors. Refer to the Anamorphic link for details.
16. Enjoy 1080i.

Other Comments:
I didn't realize I could create the overlay grid before placing the Acetate sheet on the TV screen, until I finished drawing the grid with the sheet placed on the screen. I added grid lines as called for in the procedure. I'm sure this method took much longer no only to draw the lines but some of them were difficult to see.

Part way through the convergence procedure, I became concerned that the image width was off since I did my screen adjustment with wide screen image. Thus, I decided to repeat that step with a 4:3 screen.

I confirmed the need to press 7 often to save results since after I adjusted one grid color without it, I accidentally hit a key that switched me out of convergence mode and when I switched back, all settings were gone.

Another mistake I made was not realizing that the cursor color determines which grid gets moved.

1) try doing a full clean from within the menu on the printer, or within the computer software
2) You need to perform a half test. Put a sheet of paper on the manual feeder and do a config page from the information menu on the printer. When the back edge of the paper enters the printer, quickly open the toner door to stop the printing. Now remove the toner cartridge and look at the image below. If the defect is present, then the toner cartridge is the problem 99% of the time. There is a slight possibility that during the conditioning stage of the print process the drum of the toner is not being fully discharged so when the next stage takes places part of the previous image gets put on the toner cartridge again. Very rare. If the defect is not present then the fuser has an issue.

Pages printed with dark horizontal lines the entire length of the page with a repeating (lighter) images.


I have seen bad laser scanners cause this...
A black line across the page from left to right, of various widths, at various intervals, all the way down the page.
First, though, I would reseat the toner cartridge. If the problem disappears, you are in luck!
Try another Toner Cartridge to see if the problem disappears.
It could also be a bad control board.
Good Luck.

If this problem is only happening with the black drum, it sounds like the drum is not getting cleaned correctly, and the residual toner is staying on the drum and being reapplied to the paper again. Replacing the imaging drum unit should take care of your problem.

My Ricoh Aficio CL2000N is printing several faint lines


Couple possibilities:
Fuser hot belt has wear lines transfering to the page
Black pcu needs to be replaced
Transfer unit is not being cleaned properly and needs to be replaced.
Remove each of these assy and inspect them for wear or lines that corespond to the lines on your prints.

HP Laserjet 5P shading edges of page


This is probably due to a defective cartridge, Charge Roller or Transfer roller.

Check the cartridge for a band of toner still on the drum.

Check the Charge roller for oil or smudges, this roller should be a lighter color and should be relatively free of toner or marks.

Same as the Transfer Roll, which will be dark, though excess toner should be evident.

A relatively smooth straight line is generally the cartridge.

A rather wavey or broken line is most likely the rollers.

You can however attempt to print a large amount of pages (25-50) in an attempt to clean the parts, however if either part is defective they will need to be replaced and no manner of printing will clean them.

I ran the hp toolbox "cleaning" mode too and it did not help the problem at all. I still have a dark smear concentrated in the middle of the page, and ghost images repeated lighter all the way down the page.
