Color streaks are typically caused by the photoconductor unit (which contains the drum) for that specific color, so your most likely solution is to replace the magenta and yellow photoconductor units. For the CL7200, all 3 color photoconductors come in one kit, EDP #402305. Replacing the magenta and yellow PCUs will more than likely get rid of your streaks.

If you replace the PCUs and one or both of the streaks are still there, you'll need to replace the developer units (EDP #402306) but I'd be very surprised if the new photoconductor units don't get rid of the streaks.

The reason you're not getting a "replace PCU" or "replace developer unit" message is because those messages only come up after a preset number of copies; they have nothing to do with the actual image quality and condition of the units.

If you want to make sure the photoconductor units are the problem, swap the yellow or magenta PCU with the cyan PCU (since that one isn't giving you streaks) temporarily, and see if you start getting cyan streaks instead of the other color. If that happens, you can be sure it's the PCU causing the problem.

It is leaving heavy blue streaks on everything printed


Hey, blue streaks could be a few different things. The first thing I would check is the image unit. Try swapping out the cyan(blue) image unit with another color, such as magenta. If the streaks change from cyan(blue) to magenta in color then you know the image unit is bad and must be replaced (part # 108R00581). If it is not the image unit then it most likely is the developer. The developer takes about 40 minutes to install and really should be done by a service technician.
Here is a video that shows you how to remove the image unit and where you can purchase one.. Just go to 57 seconds in the video. Hope this helps, good luck!

I have a CLC 5100 printer. I just replaced the starter/developer for all four colors. I have pink streaks on the top of every page. Whats wrong?


While replacing starter kits, it is always necessary to replace also the drum and blade for each of the four cartridges that is cyan, magenta, yellow and black. Check the cyan cartridge and make sure the developer on the magnetic roller is well spread and even then check the drum and blade and make sure no line is visible otherwise replace the drum and blade. Good luck.

I have an older Canon clc 900 Error E020 Switch power on and off again"displays when trying to copy. When I turn the copyer off and on again the same message displays.What to do ?


Error :
Intermittent E020 / E061 codes.

Workaround :
It's possible that there is a poor drum ground from the static eliminator brush. You may need to replace the static brush with the drum grounding leaf spring from a CLC 350 (part numberFA5-9308-000). Follow the procedure in technical publication CTP.NO 700/800-69.
Error :
E020 sub code 0440 and light density on all colors

Workaround :
Check the developer assembly movement, i.e. up & down and that the magnetic roller is turning. Check the EPC readings, laser output, fold back mirror, and the connectors for the developer and the developer bias contacts. If all the above checks are good, then the problem can be with the AC voltage output of the developer bias HVT. The DC-voltage for the developer bias is split between two colors ( magenta & yellow ) or ( cyan & black ). The AC voltage is supplied for all four colors and it's loss will be seen in all the colors whereas the loss of the DC voltage would affect only two colors. To fix the problem replace the developer bias HVT part # FG5-3068-060.

Oki 5150 color are not print right


You need to replace the magenta drum. Just because there is life left; it's possible it is scratched. Also, take a cotton ball dip in alcohol and wipe the LED's off when the cover is open; those black things that are hanging down from the cover. Also, make sure your drums are installed in the proper spots (magenta in magenta slot). If the toner "rubs off" after it prints... then the fuser is defective.

Yellow not printing - but only in streaks


Your yellow problem sounds like a bad yellow developer housing. Take the drum out and look at the developer housing, You will need a flash light to do so. See if the roller is solid yellow. Even if it is there may not be any developer left in the housing.
The Cyan sounds like the drum since it gets worse as it prints.
That can also be caused by the transfer belt cleaner. But that normally is the opposite. It has a rainbow sort of streak and it gets better as the machine runs.

Phaser 7700 steaks on Magenta, sometimes yellow.


Each color has its own laser. Use the cleaning wand in the front door to clean the lens covers for each color. You will need to remove the waste toner cartridge in front of the the slots to do this. If that does not cure the problem, you will need to replace the developer housings for the colors that are streaking. The manual can be downloaded at: www.lpscomputer.com/ec/Phaser_7700_Service_Manual.pdf

This should help -

Developer streak
Developer streak is characterized by a line of dark or missing toner
that stretches from the leading edge to the trailing edge. Replace the
toner cartridge corresponding to the color of the developer streak (for
example, if the streak is magenta, replace the magenta toner
cartridge).

Repetitive defects troubleshooting
Repetitive defects are defects that occur in the same vertical position
on the page, but not necessarily on every page. Most repetitive
defects are caused by problems with one of the following, and are
indicated by the positioning of the defect on the page:
 developer roller (at 38 mm)
 charging roller (at 44 mm)—see additional information under
“Charge roller set” on page 454.
 cleaning roller (at 56 mm)
 developer DSD wheels (at 65 mm)
 transfer roller (at 66 mm)
 transfer drum (occurs once per 11-by-17 inch or A3-sized page,
or every other letter- or A4-sized page)
 fuser (at 150.5 mm)
 imaging drum (at 195 mm)
 transfer belt (at 222 mm)
