The easiest way to do this if you have not got the software loaded for the printer, is open a document in word for instance, go to File>print and when the print window opens, go to properties, and see if there is a utility tab, if there is click on it and select clean nozzles.

Also have you tried looking under programs, if there is a program for your printer the maintenance tools should be there

My DSC38 printer is leaving streaky lines all over the printed sheets what do I need to change? thanks


If you have tried a new toner cartridge and that didn't fix it you probably need to put in a new drum or Fuser kit. If it is really old and has had a lot of use I would consider replacing the whole printer with a new one. The fuser kit I saw listed on Amazon for this printer was half the price of a newer printer. If you do a lot of printing or this is in a business environment make sure when looking at replacements that you get one rated for the number of pages you print a month. I have had really good luck with HP and Brother laser printers.

Color printing became faint and streaky so I replaced both the black and the color cartridges. That fixed the problem, but it recurred after only a few dozen pages. So I replaced the color cartridge...


You didn't include make and model of your printer so we can only guess. My guess is that you don't use the printer daily or for many documents and the printhead is clogged with dried ink.
I finally got tired of cleaning printheads so often and went with a color laser printer; it costs more to run but it at least prints when told.

My printer just prints in very light red


You are out of red ink, OR the print head is clogged (but that usually) produces streaky lines more so than light color.
You can try cleaning the print heads:
  1. Open the 3845 desktop assistant c00026601.gif icon on your desktop or start menu
  2. click on utilities or tools
  3. click maintenance
  4. click clean cartidges
  5. follow the on screen instructions
If that doesn't help, you're either out of ink in which case:
  1. Buy a new cartridge (or have yours refilled professionally)
or your print head is clogged beyond repair, in which case:
  1. Buy a new cartridge
Happy printing.

The printed pages are coming out really streaky. We have tried cleaning it, but no joy. Any advice?


Print a few pages. As they are printing open the cover. Remove the toner cartridge. Look down at the page that was being printed. If it is not "streaky" look at the fuser, it probably needs replacing.

If that page is "streaky" replace the toner cartridge.

C5150: All color prints are extremely streaky and


This happened to me. It was caused by a bad "oki compatable" color cartridge. One time it ruined my drum. It was always the yellow color. Decide which cartridge is printing streaky. Remove it, bang it on the inside of a large plastic garbage can. Clean it. Reinstall it . If it still prints streaky throw it befor you ruin the drum. Replace it.

My priter prints blue lines across all colored pictures or text.Any Idea?When printing black only,there is no problem.any colored - blue lines are added.I did reintal the drivers,used old and new but...


Have you tried cleaning the print heads or replacing the color cartridge? where as it it printing black fine it leads me to believe the problem lies in the color cartridge. my first recomendation would be to run the clean print head wizard in the printer settings and if that does not work then replace your color cartridge.
