Images have a streak of color in the middle

If that is the last page that has the streak use a blank page in the original scan as the last page and then the dark line wont cover the image.

Vertical streaks:
Check,which color/s streaks are appearing on print out,remove that cartridge/s check on drum surface for streaks.. if found replace that cartridge/s..check.
Horizontal streaks:
This problem appears when the cartridge/s image drum not rotating properly. Resit the cartridges properly, print 20nos of blank pages, then check.... replace the cartridge..

Replace the magenta image unit. Yellow image unit also and for the white streaks have the glass that cover the laser cleaned.

There is something on your scanner glass. Clean the glass with glass cleaner. If this happens when using the automatic document feeder, open the top side cover where the paper feeds into. There is a narrow glass strip there. Clean that as well.

If this fails, the scanner head has a bad sector on the CCD and will need to be replaced. You will probably find that it will be cheaper to replace the printer entirely if that is the case.

Assuming the document going through the scanner looks normal, there are a few things to check. If you open Capture Perfect, you can adjust the contrast and brightness as well as the thresholds. Sometimes different toners react differently to the scanner...paper is a big thing too. Multi-part forms can be tricky to get the settings adjusted so you pick up enough of the text but not that on the other side. If it's still messing up, you can try and get it serviced.

From the service manual:


Vertical lines or streaks

Check for a leak where light might be entering the printer.

Check for circumferential scars on the photosensitive drum. If scars are present, replace the
drum cartridge if the line goes through all colors.

Check for circumferential scars on the upper fusing roller. If scars are present, replace the upper
fusing roller if the line goes through all colors.

Remove the imaging drum and inspect main charger or imaging drum for a contaminant, such as
a fiber, if the line goes through all colors.
CAUTION Do not expose the imaging drum to light for more than 15 seconds. The drum is light sensitive, and
exposure to light can cause permanent damage.
Vertical black lines

The toner cartridge is defective.

The toner cartridge is not seated properly.

The fuser entrance is dirty.

The fuser has scratches on it.

This might be a repetitive defect. If so, the lines will repeat at a consistent interval down the page.

The printer needs to be cleaned.

There is a problem in the heating element.
Vertical white lines

If white lines or streaks appear only in the black areas of the printed media, print several
configuration pages to clear the anomaly. If this does not clear the problem, check the sleeve
surface to confirm the defect, then replace the black toner cartridge.

If white lines appear only in a particular color, try printing several configuration pages to clear the
error. If the error does not clear, check the sleeve surface to confirm the defect, then replace the
defective toner cartridge.

There is a lack of toner or the toner cartridge is faulty.

There is dirt in the laser path.

The fuser is defective.

A mirror in the laser scanner is dirty.

Is the scanner scanning normally otherwise? Try scanning a printed matter with white background and if it is okay, then the streaking may be because of excess brightness chosen. Check if the paper movement is at constant speed. If it is smooth paper, it may slip and the same area may scanned again, appearing like a streak.

This is going to seem dumb
If the streaks are in the direction of the lens travel
vaccum the thing out
If there is a dust crumb on the lens, it will show as a line, streak

I think your flatbed lamp is damage

if u replace or color it pure white ink

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.
