Gray continuous streaks on lower half of copy using Canon IR 1600

Just changed out the toner with a new cartridge and cleaned the rollers and the top part of the copy is fine, but the bottom half is gray. Any ideas? Thanks.

I assume you had the issue before you changed the toner, If so the problem is either the fuser or the Laser.
Do this:
start a print job and after you hear the paper feed into the machine open the top cover to stop the machine. You want to stop the page before it gets to the fuser. May take a couple tries.
remove the toner cart.
the page should be under the cart with the image on it.
If the line is on the page the problem is image development(toner or laser).
If no lines the problem is likely the fusing assm.

We have installed in our office a Canon MF8330Cdn printer. Every page that is printed now have a vertical line down the entire length of the page about 1" from the left hand edge of the page. Can you...


Her are somethings to try.
  1. Paper jam
  2. Bad toner cartridge or bad toner.
  3. Clean the corona wire (see the manual)
  4. Drum is wearing out and needs to be replaced.
Sometime a small piece of paper can get jammed in the toner cartridge roller and cause this type of problem.
Also, often this seen with after market toner cartridges or refilled cartridges. Poor quality or old toner will clump inside the cartridge roller wiper blade. Just like dirt under the wiper blade on an auto, it will leave streak on the toner roller that are transfered to the print drum.
Take a look at the toner cartridge first and inspect the long black roller. If the streaks are there then you need a new cartridge.
If no on the roller streaks try to clean the corona wires.
Also inspect the drum to see if has streak. Try wiping drum with soft tissue paper to see if it come off or is etched into drum.

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!

Our copies are streaky like the drum is not clean.... help! There is black streaks on the top of all of our copies on our canon imagerunner 3300.


A) Black Streaks, Shadows, And Ghosting
Adjust the printer's lightness/darkness setting to 2-3 different variables and see if problem disappears. Look at the fusing assembly - is the roller torn or does it have any black buildup? Use caution!!! It gets HOT!

Try another toner also.

Half looks great but the other half is gray scaled has been getting worse for about a month


1)So, your copie is half with good black color, and other half light, with possiblle white streaks?

IF YES: you need to clean the laser unit and replace the toner cylinder cleaning blade, also check the drum unit - if it got over 25000 copies change it too.

2)So, your copies are half good and half like no toner is fixated on paper?

If thats the case replace fixing roller and bushings, and check the press. roller bushings.

Try to clean the drum & shake toner & it's nothing to do with transfer roller for sure , it's your drum unit only . Another thing ,was your drum unit exposed to light for more time than normal , in that case try another drum ,try this i think that will solve your problem

Lines down both the left side of the printouts.


good day,

this usually occurs when you print large volume of copies of documents that goes beyond the printable area of the paper, some powders stick in the roller of your printer hence making the gray streak.

you can check if the rollers have accumulated some powder, if so, have the rollers cleaned.

i hope this will help.

2 IN. GRAY AREA DOWN SIDE PAPER


There are several things that can cause this. A worn toner cartridge and/or transfer roller can cause vertical smears, but it may also be a worn fuser assembly. The teflon coating on the fixing (heat) roller wears off, and leaves vertical streaks of varying widths on the pages. Sometimes you may see "ghost" images on the pages for the same reason. Open the back door of the printer, and hold down the exit guide on the fuser (carefull, it may be very hot). There are two long rollers, the lower one is black, the upper roller is either grey or shiny brown. That's the teflon coating. See if it's peeled or damaged. If so, replace the fuser assembly.
