Oki c9500 blotches

Hi
Our c9500 prints blotchy marks on every page, equally spaced every 3 inches or so horizontally across an a4 (portrait) sheet.
We've printed a full page of each colour, and it appears on all, so it's not the cartridges or drums and also changed the fuser unit.
The printer has been cleaned up in all areas as well. Any ideas?
Thanks
Dan

SOURCE: Oki C9500 makes VERY LOUD clunking noises but prints fine...

The sound is most probably from one (or more) of the drum units. You can check by taking them out and trying to run the visible gears by hand. If you have spare drums, change them one at a time until you find the defective one.

We had this issue and removing the optional hard disk fixed it for us, I'm guessing it was on the way out and wasn't really being used so it will not be missed.

SOURCE: Oki C3100 - v poor print quality

Hi Errol

The way to identifiy your problem is to send a full colour print to your printer and open the top just as the paper starts to come out . if you then remove your toner / drums for all the colours you can see the transfer belt if the quality of the image that you can see on the transfer belt is good and clear your problem is with the transfer form the tranferbelt to the paper and not any toner /drum issue and the most likley cause is the transfer belt itself "but before you relpace it remove it and clean around the electrical contact points and generally make sure the internals of the printer is free of loose toner .

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.

Black dots/blotches on the sides of printed sheets - whats is the cause and how t to fix it


If you have random blotches on both sides of the sheet, your printer probably needs cleaning, especially in the fuser section. If the fuser is difficult to get at, here's a good cheat developed for HP LaserJet 6 printers: Use a basic graphics program such as Microsoft Paint to draw three solid black rectangles about 2.5" top to bottom, going all the way across the paper (the space in between is not critical - the key is that you go as close to edge-to-edge as you can get). Print out this sheet.

Put the sheet back in the paper tray so it will print on the blank side (usually printed side up). Open up a quick text processor (Notepad in Windows). Type a single space, then print (some text editors won't print a document with no data in it). Dirt in the fuser will get stuck to the black areas on your cleaning sheet. Test your work by printing another copy of " ". Repeat with a new cleaning sheet if necessary.

At college we have a w7200, how can we print across the paper rather than down it, for example a panoramic image across the width of the paper and say 20cm high


Try selecting LANDSCAPE as opposed to PORTRAIT by using the proper print menu in your application rather than the simple print icon from most tool-bars.

You can usually find it in the FILE menus

Problem printing multiple pages on one sheet!


This is not the fault of the printer but the fault of word.

The way I did it successfully was as follow:
File > Page Setup > Layout = Landscape (sounds like you have already done this)

In the print dialoge, instead of OK, click Properties. On the layout tab, select landscape and below that select pages per sheet = 4 and then click ok... Then click OK to print.

Printing 2 pages on landscape document


Usually if you see the page in the Publisher window is already landscape, it will go landscape in the Printpreview and also in the print out. I just try to imagine what is your problem.
If I am not mistaken, this is what you did:
You have two "small" pages (maybe A5??) and you want to print it in one page of A4. Of course the A4 should be landscape.
Publisher does not have the facility to set 2 pages A5 in one A4 like in Microsoft Word.
The easiest way is just create a new page with A4, then copy the 2 pages (or you called it flyers) and paste it in that A4 landscape page.
Publisher can do print 2 pages A5 in one sheet A4 but the arrangement is as booklet. You can see the choices in File --> Page Setup --> tab "Layout" --> scroll the Publication type.
I do print 2 pages A5 in one sheet with many variations using addition software named "Clickbook".
Let me know if I m wrong in interpret your problem.

Horizontal streaks on pages


Streaks at 2.82 inch intervals: Horizontal marks at this interval are the result of a mark on the fusing roller of the printer. In some cases, these marks can be cleared up by running a cleaning page through the unit. Laser Printer Cleaning sheets can be purchased at your local printer/office supply store. If the marks persist, this can indicate a more serious problem with the fusing roller that would require service attention.

Streaks at 3.74 inch intervals: Horizontal marks at this interval are the result of a mark on the image drum of the printer. There is no way to repair a damaged photosensitive image drum, so in the case that it is scratched or otherwise damaged, the entire CRU (toner/drum cartridge) would require replacement to clear up these marks.
