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

please refer to the link below. I have read up on the cleaning sheets mentioned above and it seems that they either work or they thoroughly jam up your printer


HP LaserJet 1600 Printer Print Quality Defects

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.

Replace the cyan toner.

This is more than likely down to the upper roller in the fuser assembly. It's the heat roller at the back of the printer. The upper roller wears so paper dust and toner stick to the roller which then can get deposited back on to the page.

try performing a hard reset by holding go and turning on the printer.....otherwise you may try to download the current firmware from hp and install...

check your ink levels. if its the ink that came with the printer it is probable running out of ink. they do not give a full cartridge with printers, only about 3rd full. also try cleaning the heads. and try changing your printer settings/prefrences to less ink, more drytime see if that helps.

The streak is most likely the toner or the fuser

This is the test to determine toner or fuser issue.
Print a test page
When you hear the paper feed into the machine open the top or front to stop the machine
Remove the toner cart.
You should be able to see the page with printing on it. (This is before the page hits the fuser)
If you can see the defect on the page the problem is most likely the toner cartridge but NOT the fuser.
If the page is clean the problem is most likely the fuser.
Hope this helps

Most Printers that are laser have a transfer roller or transfer belt. If you have replaced all the drums this can often be the problem.

replace the toner cartridge or get the cartridge refilled as its about to empty .

Check your Toner Carts.
Is the line a certain color?
Black perhaps?

Lift the door of the toner cart.
If you see a streak on your toner drum, you will see a streak on your paperwork.

Look at your fuser as well.
Is there a problem with the big orange roller?
BEWARE! Don't touch the fuser roller its EXTREMELY HOT!
Let the printer cool down before inspecting.
