Pull the toner cartridge out of the printer. When you pull it out the cartridge is connected to a case (called the drum). The drum has on it a purple slider that is used to clean off the cartridge. I have personally had problems when I leave the slider in the middle, and get the same results as described. If the slider is not the issue then pull the cartridge out of the drum and clean off the excess toner. This should solve the problem.

The ink where it come out maybe dirty as it usually does when changing
go to the print operation and run a clean up system and see if the colours come up ok
this method may use a bit of your ink but if in business needs this has to be done and proves ok
if problem persists , than take the toner out and with a bit of alcohol wipe and a dry wioe afterwards, clean the outlet

I have an HP Laserjet 4, quite old, and it has developed a very prominent streak almost straight down the middle of the page. Staples told me to clean the drum, but my manual doesn't even seem to mention...


Put paper in the manual feed tray. That's the pull down door in the front.
Print something. As the page gets fed 3/4 of the way into the printer, open the top cover. Pull out the toner. Look down at the paper. If you see the prominent streak, you probably have a bad toner cartridge. If the streak is not there, check the fuser. One of the rollers is bad.

While you have the toner in your hand, you should see a flap that is the entire length of the cartridge.
Put you thumb on the flap and pull it down. You will now be looking at the drum.
If you see the prominent streak, that's your problem. See if you can clean it with a soft lint free dry cloth. If the streak comes back, the rubber cleaning blade is probably bad. Replace the toner cartridge.

I get a dark streak down the left hand side of every page.


It is either toner cartridge or fuser.
Print a few sheets of anything.
While printing, open the cover and pull out the toner.
Look down at the paper. If you see a dark streak, you have to replace the toner.
If the page is streakless, replace the fuser.

I have a one inch streak down the middle of my printed page on my HP laserjet 1600 printer


Streaks (thicker lines) indicate faulty PCR Roller which is located behind the green drum inside the cartridge. As the printer has 4 cartiridges, you have to identify the faulty one. You may replace the cartridge or get the PCR Roller changed by a professional.

Let me know if any further clarification is required. Hope this helps!

What does the streak in the printed sheet mean?


You have to replaise the drum... But before you go out and get a new one cause they can get expencive. Take the toner out of the printer and give it a good shake just to make sure that there isn't any clumps

Printed pages look terrible...


I'm more familiar with HP printers, but it sounds like a fuser is bad. The fuser effects print quality as well. If you've replaced the toner, as you have.

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)

Dark toner streaks


can only be toner, drum or fuser, pull out drum and look at surface are you streaks present? usually drum.

Stop a print half way threw machine and then remove drum and look at print, pre hot bit (fuser) are you marks there? If so it is drum, if not fuser.
