Streaks & Smears after changing toner cartridge.


Remove all of your toners and clean them off. Replace each one and make sure they are well setted in the unit before going to the next one. Make sure the carosel turns smoothly and nothing is hanging up on the sides. Reboot the whole printer and let it settle for 5 mins before printing. toners come lose sometimes when you turn carosel around. Hope this helps you these printers are a ***** to deal with ,but when they are right there great.

Hp 4550 vertical line down center of page


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.

HP Laserjet IIIP starting printing thin vertical black line


Was this happening before you swapped toner?
Is there toner streaks on the drum? Yes? Defective.
What if you stop the printer (open cover) as it passes through the fuser to determine if image is from drum or fuser?
But really....isn't it time to move on anyway???

Prints black vertical line at bottom of page on every print. HP 8550gn


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)

2 Missing ink black streaks


Check the dev unit for missing lines. Also clean the laser glass with the supplied cleaner pad - though if the problem were caused by toner on the lens, there would be gaps in ALL colours.

Check the dev units first. You can also do a stop test whilst a full colour test image is half way through printing and see if the lines are missing off the image on the PCU as well.

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.
