Question about HP LaserJet 4 plus Printer

2 Answers

Dirty, smuggy, pages

I have replaced the toner cartrige and the drum and added fresh toner. I cleaned the inside under the cartrige because toner had spilled and then cleaned the Transfer Roller. Not sure that was okay to do but I did it anyway. I got a few really good clean copies but after the third one the smuge slowly came back. Back in 2002 I replaced the Fusing Assembly and I suspect this may be the culprit? I am not sure if I should pursue the Fusing Assembly? Could this be the problem or is there another part I am not aware of. Is there anywhere I can buy parts for this printer. I really love it and it has been a great work horse and don't want to give it up. Thanks.

    Tried to rate but did not go thru. sorry. Thank you both. I tried the first option and found the smuge was there. I tried the second option but got lost. When the paper is coming out it is alread in the back and has gone thru. Did not understand where the fused portion is. It seems it is probably the toner cartrige. It is relatively new so I guess I got a bad one. Will buy a new one and try again.

    Thanks a lot for all your help.

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 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 smudge or marks on the page the problem is most likely the cartridge but NOT the fuser.
If the page is clean the problem is most likely the fuser.
To confirm run another test page and open the lid as soon as you see the page start to exit the machine.
Remove the toner and pull the page out from inside the machine.
If the marks are on the fused portion of the page but not the unfused portion the problem is the fuser.
Fuser is readily available.
Hope this helps

It still sounds like a bad toner cartridge.. Try for buying parts. does not sound like a fuser problem.

Toner cartridge drum gets full of toner spreading it all over machine inside

Chances are your waste toner bin is full. Depending on the printer, that will be in the drum unit for printers like a Lexmark. In the printer cartridge for HP, or in the transfer belt for most color printers.

Oki b410d printer has a new toner cartridge however it is still printing inconsistently on the page?

Open the lid. Mounted under the lid you should see a horizontal bar which is actually the laser [LED]. Once your toner cart has emitted, enough loose toner has accumulated on the laser that it can no longer draw on the page correctly. Using something soft and barely dampened with water [use a soft cotton cloth, NO PAPER PRODUCTS, no dirty rags, etc] and wipe gently from L to R to remove the loose toner. Turn to a clean section of the cloth and do it once more. GENTLY! No pressure, do not scrub it, or you can damage the laser. Close the lid and print something. You should be back to good now.

Sharp 1641cs - Dark/black page after replacing drum & toner

Hi you have not said the toner type you replaced with though that will give not completely black copy. The problem may have been the drum unit installation. Make sure the charge unit over the drum service is present ie the one with a mesh wire like grid. If present, clean it or wipe with a soft clean and dry cloth. Clean the saw-tooth like metal plate inside that unit by slow blowing and make sure no toner particles are there. Finally screw the unit properly on the drum unit and your problem is solved.

HP Laserjet P2015 serires Could you advise me on how to get rid of a black line appearing down the centre of the page when I print please? Thank you.

Dirty print out is basically due to cartridge related issues. HP Laserjet P2015 uses HP53A Cartridge.Take out the cartridge and inspect it under torch light. You would notice the line(s) on the green drum. Gently clean its drum/ (green roller) with a dry, soft, lint-free cloth. The drum is located under a cover which can slide with a little push. Checkout for any spilled toner inside the printer and clean it also. Print a few pages so that the parts get further cleaned. I think, this would solve the issue.
Please note that, this step may help temporarily, if the cartridge and its parts are worn out. In that case it is always better to replace the toner cartridge.

Moreover, streaks (thicker lines) and dots etc indicate faulty PCR Roller which is located just behind the green drum inside the cartridge. Try to clean it too. It requires a bit of improvisation because it is difficult to clean it fully. If the problem persists, replace the toner cartridge with a genuine one or get the PCR Roller changed by a professional. If the cartridge is old

Let me know if any further clarification/ assistance is required.

Hope it helps! Good Luck! Thanks for using Fixya!

Printer is leaving yellow streak down right side of paper

That usually happens when a toner cartridge is getting low or old.
Replace the yellow toner cartridge. If you have done that then the other most likely solution is that you need to change the drum.

Dirty Copies are printing

Remove the black cartridge, check the roller in front, does the roller evenly disribute the toner? if not change the cartrige. Do the same for other cartriges.

The printed pages have a black lines that block out words or images printed under the black lines. I am using a friends Brother HL-5270 lazor printer, she has lost the manual. Six months ago, I took the...

The inside could be dirty, blowing it out could help, but first try taking out the toner and drum and cleaning the corona by running the blue tab near the front back and forth about 20 times and then blow out that area with a can of air. If you can see the lines on the drum, you may need a new drum.

Hello, i got toshiba 7660 photocopier. It keeps showing 'adding toner in process' on the screen, and throwing the developer into the waste toner container.

The drum ground circuit is defective, this allows excess charge to build up on the drum surface and "pull" developer material through the cleaning system. This circuit needs to be troubleshot and then replace developer material with fresh devo, then run AT (auto toner)
Also, would recomend cleaning out Drum Cleaning Unit, otherwise the drum will be scratched from devo against drum blade/drum.

Gestetner DSc224 starts to print black strips inside colorpages

the printer in the service program has a option for the printer to do a process control on selected number of copies that number for your machine should be lower because you print about 150 duplex pages an that is 300 single pages so go in the service menu and set the process control on some 30 pages to be done .
Follow the next procedure:
- For to enter the service mode:
1. Press the clear modes key(the yellow key)
2. Type “107” at the numeric keypad.
3. Press the clear/stop key(red key)
and hold it down until the screen
display changes (for about 3 seconds).
4. Touch “Copy Sp” on the touch screen.
In the upper right corner on the touch screen has a key named [Sp Direct],touch that key and enter with the numeric key pad the numbers:3003 and on he screen will appear [Lubricant Interval] set the interval on 30 pages and press the "#" key for to confirm the value. After that for to return to normal mode press the exit key on the touch screen several times.
Also do the [maintenance -clean/adjust] option once after 1000 or 500 pages printed. Because this is a office machine and when you print on her a lot of pages per day the machine start to get dirty.

Toner showing empty

first, if you refilled your toner, the printer will always tell you, that you are not using original toner and red light will blink. second, if printer tell you every time to replace different color, then you need to clean a chip reader and chips on toners. take out all toners and pc drum. under toner rack there is a chip reader, clean it with pressure air and reinstall
