My hp1312 is printing a black line on prints. I have checked the cartridge and that is fine. Can I clean the fuser?

If your Toshiba photocopier is not printing in black and white but is printing in color, there are a few possible causes and solutions to try. Here are a few things you can try:

1. Make sure the machine is set to print in black and white. Some photocopiers have a setting that allows you to choose between color and black and white printing. Check the settings on your machine to make sure it is set to print in black and white.
2. Check the toner cartridges. If the black toner cartridge is full but the machine is still not printing in black and white, there may be a problem with the cartridge. Try removing the cartridge and shaking it gently to redistribute the toner inside. Then, clean the contacts on the cartridge and the machine to ensure they are making good contact.
3. Check the fuser unit. The fuser unit is responsible for heating and fusing the toner onto the paper. If the fuser unit is not working properly, it can cause the machine to not print in black and white. Check the fuser unit for any damage or debris, and clean it if necessary.
4. Check for any error messages. If your machine is displaying any error messages, try to troubleshoot the problem based on the specific error message. You may be able to find the meaning of the error message and a solution in the user manual for your machine.
5. If none of these solutions work, you may need to contact Toshiba for technical support or service. They may be able to help you diagnose and fix the problem with your machine.

Black lines on copy come from toner cartridge, or drum unit, or fuser unit which is in the back. check drum and see if you can see line, back of machine with flash light you may be able to see line on fuser roller. Be carefull Fuser is hot.
A copy that is good and then starts to get lines usually the drum unit...

Two thing we have to observe, is it cartridge faulty? or Printer?..
> Replace with another cartridge check the quality. if it rectified replace with another cartridge..faulty cleaning blade in catrdige cause of vertical lines in print outs..
> Might be teflon sleeve got damaged, replace the teflon sleeve if available or else replace fuser assm..

I could be wrong, but I think it's in the toner cartridge. The drum - the roller that the image is formed on - has a soft, plastic blade rubbing against it to clean off excess toner after each print. If a clump of toner gets stuck under the blade, a line is printed down the page where that part of the drum isn't cleaned as well. Between prints, the drum keeps turning, and may be able to clean itself better than in a single revolution. It's a theory, anyway.
Pull out your toner cartridge and look at the drum to see if there's a black line around it at one end. You can't get to the cleaning blade without risking ruining the drum and the cartridge; the cure is just to get a new cartridge. If yours is fairly new, take it back to the store that sold it to you, along with a print sample. They might exchange it.
If the drum doesn't have a line around it, you can test it by deliberately jamming the machine. It's scary, but if you've unjammed jams before, you can do it again. Start a print job, then kill the power when you think the page is right in the middle of the printer. Open the printer and remove the toner cartridge. Look for that black line on the page before it reaches the drum, between the drum and the fuser, and past the fuser. (The fuser is the pair of hot rollers that pinch the page tightly and melt the powdered image into the paper. Any part of the image that hasn't made it into the fuser is still powder and will rub off.)
If the line doesn't show up until after the hot rollers, then I was wrong about the toner cartridge, and you're looking at a fuser problem.

Problem :
Vertical black lines

Cause: Contaminated fuser entrance guide Solution: Clean the guide

Cause: Defective toner cartridge. Solution: Replace the toner cartridge. ( By far the most common cause)

Cause: A "video line" generated by a defective formatter.
Solution: Replace formatter

Cause: Worn fuser film. Solution: Set the fuser to a lower temperature mode. Replace the fuser. Note To prevent the print-quality problem, reduce printing on large volumes of narrow media, such as envelopes. Instead, alternate smaller volumes of narrow media with full-page printing jobs.

Hope this helps.
Good Luck

To tell if it's the fuser you can do a half way test, what you have to do is print a document, and open the front door of the printer to stop the print job half way through, you should see that half of the toner is fused to the paper and half is just applied to the paper, if you see the black lines on the fused side of the page its the fuser if you see it on the entire page it could be the etb or the cartridge.

possible fix:

This is a common issue with laser jet printer,

Try running cleaning modes under the service menu on the printer, run 5 back to back. if the issue is still showing, try using a different cartridge and run the cleaning mode again. If you have an old cartridge even if its close to being empty you can do an override on the printer to test the cartridge:
1.press ok
2.use the arrows and navigate to the system set up menu
3. press ok
4. print quality
5. press ok
6. override out
7.press ok and again ok to set

This could also be a build up of toner in the fuser assembly, and you may have to adjust the fuser temperatures in the embedded web server. You can print a blank word document (20 pages) and see if you still see black dots, if you do it is likely to be the fuser, set the driver and printer settings to card stock or heavy in order to heat the fuser more than the usual temp and print 30 blank pages this should resolve the issue. if this does not there could be damage to the ETB or the fuser assembly and servicing of the printer would be required.

take care,

...maybe its time to replace fuser fixing film!?

You may need to replace the toner cartridge or the fuser assembly.

If you open the toner cartridge door and see a black line on the roller, you will need to replace the cartridge.

it is the problem humadity or laser mirror is dirt clean it and then solve your problem

yes you have to catch printer making the line and then as a page is being printed you need to open door to stop paper after green cylinder(drum) as it is entering fuser, then you need to remove paper from printer without pulling through the fuser, if you see the line then rub your finger across line up and down page, if it smears at all then its the cartridge if not then the fuser
