Question about Office Equipment & Supplies
There are two possible solutions. Is the machine sitting on top of metal? The machine will send black pages when there is static charge. You can put a rubber mat under the machine or use a static guard. The second solution is to put the machine in maintenance and reset the scanner. Unplug the machine, put your finger on the menu key first and then re-plug the line while holding the menu key, in about 30 seconds all the lights will flash and the display will say maintenance. Release the menu Key and press 55 and this will reset the scanner; if scanner error comes up the machine will need to be serviced. Press stop and then 99 this will exit you out of maintenance. If the machine does not have an error try making a copy of blank sheet of paper and see if there is any improvement. As a routine clean the scanner glass with soft lint free cloth and isopropyl alcohol also.

SOURCE: problem with images
I found this by searching on the 2050c. I read this and it did not help much but I got to thinking the scanning was done by a narrow slit and my verical lines running the lengh the image had to be dirt on the slit.
I got some very good quality color printer paper not real heavy maybe even 20lb and ran about a hundred pages throught the scanner. Slowly the lines faded to white even at 800x.
I did take a slightly damp soft cloth and wipe the area where I thought the slit might be. We have 2 of these scanners and the other had a faint line too and while I was on a roll I ran pages through it.
Maybe this would work for you. In any event it almost has to be something on the scanning part.

It sounds like the CIS (scanner) has failed in both machines. Its no generally not a common problem. I would change one every six months if I was lucky.
It may point to something in your environment. I have have seen rust build up on the contacts of the scanner cause this problem. So if you have high moisture or are close to the ocean this maybe a problem.

If the print can be rubbed off then this suggests the fuser unit is not working correctly. It could be that the thermistor is covered with toner and making the machine think the fuser is hot enough when it's not.
The black line could also be caused by the fuser if one of the pick off fingers is coated with toner or has worn into the Teflon of the roller.
Does the machine show the lines when you print a page from memory - such as a counter or config page? If not, this would suggest the optical path is dirty. Try cleaning the glass and look at the mirrors inside the scanner to see if they are dirty/dusty.

SOURCE: when the fax machine prints
1-take out cartridge and clean the inside , there may be toner on the lamps
2-take a look at the drum(shiny cylinder) does it have black rings?? replace
3-does it have scratches or grooves? replace
3-could be the lamps (long thin strip of lights) some of the lights are bad
