When printing or copying the ink can be rubbed off, this is usually down the middle of the paper. Any idea which part is at fault, jets, imaging drum ?

There are 2 possible things that could be at fault here. One being the image is'nt fusing to the paper due to faulty operation of the fuser. If any of the toner/image on the paper is easily wiped off the paper then this is more than likely the issue. The second possible issue is that you have a bad drum unit, there is an internal cleaning blade that is used to scrape the excess toner from the last image off before creating another copy. On this particular machine the drum only comes as a unit and would need to be replaced. More than likely you need a new drum unit. P/N- 9630A003AA

You did not say what kind of printer. Laser printers-- Look at the innards (Toner, image drum, fuser,etc) for something in the same location on the various parts. This is kind of general, but the cause is often obvious. Printers can also have this problem if memory locations have failed, or, in the case of some laser printers, the laser unit is malfunctioning.

Ink Jet printers. Usually caused by something in the paper path after the print head, or the print head. Cleaning the surface of the print head with a lint free damp towel may cure the problem. Duplex printers can get crud in the duplex assembly that will cause this symptom.

In other words, it's most likely a hardware related problem, not software

Try a "head-cleaning" cycle -- if the ink inside the cartridges is not getting through the print-head mechanism, then nothing will reach the paper.

Given that a replacement HP printer will be inexpensive, when compared to taking the printer to a qualified service technician, I recommend that you responsibly recycle the printer, and buy a new HP printer that uses the same ink-jet cartridges as your current printer.

Sounds like it will either be the drum/blade or the fuser unit.Try turning the copier off when copying just as the paper reaches the fuser.remove the 'jammed' paper from the copier carefully as the image will rub off.If the lines are there then it is more than likely the drum.

The two problems may not be related. Adding toner should not under most circumstances cause copies to become light, unless the toner you are using is of a poor quality - I hope it is a Canon cartridge or quality generic. It sounds as though your fixing film or drum unit may need replacing, or perhaps you need to perform a install procedure. As the 'install - toner - start' option is free, try it first:

First press the head key and then the number '2' and '8' keys at the same time then press the head key again. This will take you into service mode - select 'copier' then 'install' then 'toner' then 'start'. This will run throught a cycle that takes a little while, I think about 599 seconds (sorry for been so accurate but unhelpful but that's what I remember from the display - never converted into minutes but you're welcome to).

But if you are having blurry or even dirty or light copies it may be the fixing film. When the copies are printed, immediately check if you can rub off the toner at all by rubbing the print with your fingers - if so this indicates that the fixing unit is not hot enough or there is not enough pressure - check that the fuser is in properly and that the jam release lever is not engaged.

Lastly, it could be your drum unit that is faulty or worn. Totest this you will need to try and stop the machine in the middle of printing before it reaches the fuser - open the front cover and latch down the transport bed with the green handle - remove the paper gently so as not to disturb the ink in any way and observe the image quality - if it is displaying the exact same symptoms then it is not your fuser and is probably the drum unit or dodgy toner - most likely the drum. However, if the image is fine, then it most definetely is your fuser film (and or perhaps the cleaning roller that cleans the film).

Good luck

The best way to tell if your problem is clogged jets, or bad maintenance kit, or something blocking jets. Is to look at light stripes test, and see if missing jets are all in a straight row or all over the place. If the missing jets number less that 10 you can use jet substitution to avoid the streaks. If you are using Media Sciences or some other after market ink, check that most of your problems are not in the cyan area. Media Sciences produced a bad batch of cyan which clogged the jets pretty bad. The good news is that if their ink caused the problem they will pay for some one to come out and replace your printhead. If you LST (Light stripes test) has a smear the entire vertical lenght of the page. You have either a bad maintenance kit, or a piece of paper, lable etc..rubbing against the drum while printing

Hi jbasset285: Your printhead may be bad do to third party ink.
Try these steps first.
Diagnosing Print-Quality Problems
The Troubleshooting Print-Quality Page provides a good overview of the most
common print quality problems. To print the Troubleshooting Print-Quality Page,
follow these steps:
1. From the Control Panel, scroll to Troubleshooting, then press OK.
2. Scroll to Print Quality Problems, then press OK.
3. Scroll to Troubleshooting Print Quality Page, then press OK.
The Troubleshooting Print Quality Page includes instructions for printing the
Eliminate Light Stripes test print. These instructions are also provided on the next
page of this manual. The Eliminate Light Stripes test print indicates individual weak
or missing jets or an obstruction in the imaging path that affects a vertical band down
the entire page. Also, you may see color variation from jet to jet on the Eliminate
Light Stripes test print. Some variation is normal, occasionally occurs, and usually
self-corrects within a few printed pages. If a print-quality problem is not resolved
with the information provided in the Diagnosing Print-Quality

You can clean it, thats a good idea but,,(and this is messy) roll back the master.. take out the ink cartridge, use a rod to squeeze some ink onto the area, and smooth it out into the screen with a plastic scraper.. Lay the master back over. Keep scrap paper around and print a big black square and run a couple hundred sheets through.. This will work. Messy but will work. If you don't want to manually put some ink on the area.. Print a large black square and run a couple hundred sheets.. see what that does.

Can only be two things the drum or the fuser. More than likely drum they last about 4 toners i think.

Learn the art of getting a page to stop halfway threw printing, you want to stop the page after the drum has put a image on the paper but before paper has gone threw the fuser (hotbit).

Once you have mastered the position correctly by stopping the printing by opening the door and removing drum/toner cartridge, to reveal the paper that is printed but can be rubbed off, we will know if marks are coming from the drum (you will see them) or from the fuser, if print is fine.

Yes Cartridge problem is what causes double imaging 95 % of the time, there is a rubber blade in the drum unit that wears and doesn't clean off old image from drum. Have known this fault to be fuser at times, the way to tell is to get a print to stop half way threw machine by openning door during print, remove cartridge and look at print, you want it to be stop before the fuser(hot bit) but after the drum, image still rubs off if pre fuser and then you can see if defect is present before paper travels threw the fuser, but in your case I think you will find it is not the fuser it is toner cartridge.
