I am using win98se. The first copy I print has light vertical strips on page where the print is gone or may print light. These strips may be 1/4 to 1 inch wide. Subsequent copies are considerably better. However it seems the print is not as dark as before. I have tried a new toner, drum assembly, cleaned the primary corona wire and wiped the scanner window. No help. Any suggestions. The fact that the 2nd page prints better may be a hint to the problem to someone in the know. Thanks for any help.

Re:
It sounds like your transfer unit may be at fault. There may be a scrap of something caught somewhere in the mech or it could be that the unit is scratched or otherwise damaged.
Try changing the unit.

For copy jobs, clean the glass with a soft clean cloth, regularly, not just the 8.5 x 11 screen but the 11-inch x .5 inch strip that copies when using the document feeder. Print job: their is probably dirt or ink on the rolling parts. Q-tips are good for cleaning this up, careful, don't burn your fingers.
Does this happen when you print, or only when you copy? If you print out a configuration or user settings page, or print a page from the computer, is it also missing two vertical lines of print or is it only when you are copying?
If it happens when you print, you may need a cleaning, or you may need to replace the toner or drum cartridge. If it's an inkjet machine, there's a possibility there is some ink or grease on the encoder strip (a small belt-like plastic strip that goes through the print-head carriage).
If it only happens when you copy, test both the flatbed and the document feeder. If it happens on both then you may have a bad scanner. If it only happens when using the document feeder, you likely have some whiteout (or something) on the glass. When you make a copy in the flatbed, the scanner moves across your document. When you make a copy using the document feeder, the document moves across the scanner. In this case, if there is anything on the scanner glass (like whiteout) your copies will be missing a vertical line of print data (it could be white if there is whiteout on the glass, or it could be dark if something dark is on the scanner glass).
Usually you can lift the flatbed cover and look at the glass to see if anything is on it (usually at the left side of the scanner). Clean the glass, first with alcohol to remove the obstruction, and then with a little windex to remove anything the alcohol may have left behind.
Most likely a page was scanned with 'white out' (Liquid Paper), still wet on the page. As the page feeds over the scanner, (a narrow strip of glass that runs across the width of the page along the feed path) the wet liquid paper comes off on the glass as a thin line and dries. Thereafter, when copying, the scanner light does not go through the liquid paper streak and the result when printed is a thin vertical line that runs the full length of the page.
If this is your problem: follow the path that the paper travels when sending a fax or making a copy, until you find the scanner (narrow glass strip). Take a clean, soft cloth and a small amount of methylated spirit (or white spirit) and remove the now dried Liquid Paper from the glass. Clean the whole strip ensuring that the glass is left clean and dry.
Dirt. Open the ADF, the top of the scanner/copier. The ADF glass is the thin strip of glass on the left. Damp cloth with windex or any glass cleaner. Scrub the strip of glass.
you need do follow steps: 1) take out the cartridge find a cover there is the drum inside, the drum you can see the color on the drum surface
2) check out and clean any pieces of paper or dirty waste toner stuck there, because there is a waste toner cleaner on the drum surface which is like a long rubbon strip (something like that) you can spin anyway a little to clean.
3) if you check out any different color (vertical round drum), that is the drum surface worn or scratched. you can see the worn area show light color than normal area. so you need change it better.
4) if the color all very same and still not fix, you need check again something stuck the drum surface near cleaner rubbon.
hope help you fix it, please take a rating let me know how much helped you thanks! keep in touch your question please.
There must be a strip of glass about one inch wide, next to
the large glass. There is the problem !
Clean that strip thourougly. When you use the feeder the pages
are scanned thru the small strip of glass.
I had a hp 3050 yesterday with two vertical lines running down the page when making a copy. All I had to do was to pull open the top cover where you put the paper you want copied and cleaned the glass strip with a rag and alcohol and the lines were gone.
If the problem only occurs when using the document feeder, the problem is not usually caused by the drum. When using the document feeder, try to notice where the scanner (the light assembly under your scan glass)stops just before the paper is being fed. Some multifunction machines have a small piece of glass that is separate from the large scan glass and the scanner assembly stays parked underneith it as the original is being fed over it. Most likely there is something on the glass where the scanner parks as originals are being fed thru the feeder. When putting your original on the large scan glass to copy, the mark on the glass will only show as a spot, but will show as a vertical line thru the whole copy when using the feeder.
