I changed my black cartridge, which was low. Now I get color bleeds, mostly yellow, in vertical streaks, on the printed paper.

THE PAPER SELECT ARE NOT COMPATABLE, SELECT LGL IS EQUAL TO 8.5/14 FLSC IS EQUAL TO 8.5 /13. TRY TO SELECT BLACK COLOR OR CLEAN YOUR DEVELOPING UNIT.

You can try changing the print density under print quality in the control panel. YOu can also check the reset to factory default and see if this helps. It could need what is called a maintenance kit where the fuser and rollers are replaced. I install these all the time and sounds like this is what you need.

Try using the HP Print Diagnostic Utility in Windows - HP Customer Care (United States - English).

Post / thumbs / testimonial are welcome!

when you open the front of the print you will see the streaks on the black transfer sheet.

Close the front door half way or until all the cartridge doors open.
You will see the same streaks on the problem cartridge(s) as on the transfer sheet.

Change that particular cartridge, let the printer recalibrate, and presto streaks are gone.

You can dab the bottom of the color cartridge on a damp paper towel, check the streaks left behind, if there is no yellow either there is no yellow in the cartridge or it's just plugged. Dab it a few times on a wet towel, if still no yellow, you need another cartridge.

Issue: Banded or streaked prints
Solution: Change the Print Quality Settings (Windows)

Change the Print Quality Settings (Windows) The Quality setting controls how finely ink droplets are placed on the printed page. Depending on the type of paper being used a higher Print Quality setting does not always insure a better print. Print speed will decrease as the Print Quality setting is increased. Follow the instructions below to change the print quality settings in the Canon printer driver for the Windows operating system through a printing application.

1. Click 'Properties' in the Print dialog box.
   
   Note: Depending on the Application software, 'Properties' may be displayed as 'Preferences'.
   
   
2. Set the desired print quality in the 'Print Quality' section.
   
   
3. Select 'High', 'Standard', or 'Draft / Fast'.
   

To set more detailed print quality settings, follow this procedure:

1. Select 'Custom' and click 'Set'.
   
   
   
   
2. In the Set Print Quality dialog drag the slide bar from 'Fast' to 'Fine' to select the print quality.
   
   
   
   Note: There are five options in 'Quality'. However, selectable options are limited depending on the media type.
   
   
3. Select 'Auto', 'Dither', or 'Diffusion' from the 'Halftoning' section.

The following can cause bands (vertical on a normal page)


Faulty Toner cartridge
Faulty Drum Unit
Faulty Transfer Belt
Contaminated Fuser
Damaged or dirty LSU glass

Most of the time when I find this happening on a printer, not just Ricoh's it turns out to be the PCU (photo conductor unit). The color PCU is one unit and the black is a seperate unit. Hope this helps.

Check to see if you have a paper jammed near the drum near the color ink cartridge interface.

Without actually seeing a print sample or the machine, my bet would be on the black print cartridge. Even though it reads a an acceptable level of toner, the cartridge itself sounds like it has developed a proble. 1. It's the most obvious 2. It't the cheapest place to start. If it does not correct the problem, you can still use it later. 3. It's the problem in about 80% of these types of cases. 4. I know it should be fine, but if things didn't go wrong, I wouldn't have a job! Let me know. If not we'll investigate further. Ed
