FPD-350 First copy comes out dark, not the entire page, moves threw the page. After that copies are fine, only happens at turn on or after it has been in stand by. It looks like a bias problem, I'm thinking a week power supply or bias board. Changed coronas and grid, dv, imiage is kinda weak as well. Paul

fuser drum is bad. photocopier use electricity to transfer the toner to the paper, then it is heat fused to paper. it appears that the problem is occurring around the time that the toner is attracted to the paper.

THE CARTRIDGE PORES ARE PARTIALLY BLOCKED USE FORCED COMPRESSED AIR TO OPEN OR BLEED THE PORES AND THEY WILL WORK FINE

The document feed rollers may be dirty/worn which is causing the paper to come into the scan area late causing your document cut offs. use a clean, lint-free cloth dampened (not moist) with water and clean the document feed rollers. Confirm they are dry then, try scanning multiple pages and see if they pull through without stalling. If they do, it's time to replace those rollers.

The cartridge or Toner is splitting out more ink.... Remove the cartridge Clean it and place it again.

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.

change the ink cartridge & get your printer serviced

There should be a light/dark slider on the LCD display, just move it up towards the darker setting.

Clean the optic section,the mirrors,lens and axpolamp.Clean the charge corona wire and grid and the transfer corona wire.

Try replacing the cleaning blade on the drum.

Test page printed properly. Don't know what to look for in the test page or the applications. the cartridge was changed recently
